1080P HD Pro Grade WiFi Streaming Mini DIY Pinhole Hidden Camera Kit
Q. How easy is it to set up this hidden camera?
Setting up the HC100w is simple and takes about 5-10 minutes. Just download the streaming/setup app, charge the camera kit’s battery (or plug into AC power), and configure using the app on your smartphone.
Q. How is the pinhole spy camera kit powered?
The camera kit can be either battery or AC powered, depending on your specific recording needs. In battery power, the camera can operate up to 4-5 hours on a single charge. For longer term use we recommend using AC power for 24/7 operation with no battery life concerns to worry about.
Q. Are there any fees to view, stream, or record my video?
No there are not – all you need is your existing wireless internet connection.
Q. Can I add multiple cameras to monitor different areas of my home or business?
Yes you can – you can view as many cameras via the app so you can monitor multiple rooms or areas. You can even have cameras in different locations (ie. one at home and one at your office) and monitor them all from the app at once, assuming each is connected to a WiFi signal at their respective locations.
Q. How do I watch my live streaming video?
To watch your live streaming video, you simply need to open the app on your iPhone or Android device and click on the camera you want to view.
Q. What are motion detection/activity alets?
Motion detection alerts are handy because they allow you to get instantly notified if your camera detects movement or activity, which meakes it ideal for home security or office security when you aren’t around.
Q. Can I record my video too?
Yes you can – in addition to live streaming, you can also record video to a micro SD card hidden inside the camera kit. The HC100w accepts up to a 64GB memory card, which can store dozens of hours of video.
Q. Can I adjust different camera settings?
Yes you can – via the app you can adjust over a dozen different camera settings including video resolution, streaming quality, time/date stamp, motion sensitivity, contrast, and many more. This allows you to customize the streaming and recording to your exact needs.
Q. Can multiple people watch the stream at once (such as my spouse or partner)?
Yes you can have multiple people able to watch the live stream at once, so for example, if you wanted to install the streaming app on your spouse’s phone so you can both watch your cameras at home, would just need to enter the camera ID and password in the app on the second phone so you can both watch it.
Q. Do I need any special WiFi network or router for this camera?
The HC100w is compatible with most wireless networks. A 2.4GHz signal is needed, which most routers have. Some networks may have additional layers of security (such as public WiFi networks like a coffee shop or business) that may need additional steps to connect properly, so if you are unsure of the security requirements for your specific network make sure to contact your network administrator to ensure compatibility.
Q. How do I watch my recorded video files?
There are two ways to view your videos recorded on the memory card. The first is to remove the memory card and insert into the card reader in your computer (PC or Mac) and double click on the files to play. We recommend VLC Media Player for playback for best performance. You can also remotely download the videos to your smartphone to view, however this can be time consuming since the files can be large and depends on your connection speed.
Q. What if I don’t have a WiFi network in my house? Can the camera operate in P2P mode?
This camera is primarily designed as a WiFi streaming camera, however you can operate it in P2P mode if you prefer. P2P mode allows you to stream to a smartphone nearby using short-range P2P connection, which allows you to monitor the camera feed from up to 15-20 feet away.
Q. Can I live stream to a PC or Macintosh desktop computer or laptop?
The camera streams to an iPhone or Android device only, it doesn’t stream to PC or Mac computers.
Q. Can the HC100w be used outdoors?
The HC100w is not a weather resistant camera, it is designed for indoor use only.
Mini Pinhole Camera, Cone Lens, Analog CCTV, 1080p AHD, HD-TVI, HD-CVI
The MINI-CN4 is a pinhole camera with mini cone lens that can be used in security call box, ATM, and hidden spy surveillance installations. The only part of this security camera that needs to be exposed is the very end of the cone shaped pinhole lens. The rest of the camera housing can be completely hidden / concealed inside of any object. Some CCTV Camera Pros customers hide these cameras inside of walls, clocks, and toys. Custom hidden spy cameras can be fabricated from just about anything to conceal these mini CCTV cameras.
Tiny-Sized Pinhole Camera
Here is a picture of the MINI-CN4 next to a US Quarter coin to show the tiny size. The camera is enclosed in a square case that measures 25mm(w) x 25mm(h) x 18mm(d). The u-shaped bracket swivels and allows for simple installations inside of ATMs and gate call boxes. Celling and wall mount installation is also supported.
This camera is hybrid analog CCTV / 1080p HD-over-Coax. It supports analog 960H resolution and 2 megapixel / 1080p video resolution via AHD, HD-TVI, HD-CVI formats. This means that it can be used with legacy analog CCTV DVRs and the latest HD security camera DVRs. The video modes can easily be switched using the video format selector joystick.
The camera has an advanced OSD menu that can be accessed using a small push-button joystick located on the video cable that can adjust settings such as backlight compensation, day/night mode, color, contrast, sharpness, hue, gain, and more. For most users, the factory default settings work great and the camera simply needs to be powered on and connected to a video output.
This camera comes with a 4.3mm cone-style pinhole lens which provides a fairly wide angle of view (about 63 degrees). You can see the angle of view and excellent video quality this camera captures in this sample
surveillance video and these
sample snapshot images.
This camera is typically connected to a
CCTV DVR to record video surveillance. However, if you would like to connect this security camera to a TV instead of recording, please refer to this BNC to HDMI converter add-on. You can select it from the options drop-down above.

If you’re hoping to keep tabs on your home but don’t like the look of unsightly security cameras, a hidden camera might be the perfect home security solution. These compact cameras are much easier to incorporate into your decor, giving you peace of mind without announcing their presence.
Hidden cameras come in many shapes and sizes. Some resemble miniature security cameras, while others are incorporated into phone chargers, clocks, or other household fixtures, allowing them to hide in plain sight. When selecting the best product for your needs, consider the camera’s battery life, where it stores footage, and whether it has features like Wi-Fi connectivity or motion detection.
With these considerations in mind, here are the best hidden cameras to keep your home secure.
Our top pick is the Blink Indoor Camera (view at Amazon), which is easy to conceal in your home and can even be monitored via your smartphone. For an even smaller camera, consider the Sirgawain Mini Spy Camera (view at Amazon) which records footage on a memory card and boasts 1080p HD clarity.
The Spruce / Sage McHugh
The location where you plan to use your hidden camera will determine the best product for your needs. Think about: Will the camera be outside or exposed to the weather? Does it need a wide-angle view to capture the whole room? If it’s motion-activated, does it need technology to rule out false alarms? You’ll be able to narrow down your selection as you define which features you need.
Another important consideration is the quality of the video. Since hidden cameras are tiny, the quality may not be as good as a standard camera. Get a product with at least 720 pixels; otherwise, you may not be able to make out the details in the footage.
Some hidden cameras only capture motion-activated clips, while others record continuously. Look into which method your camera uses, as well as whether the video footage is stored on a memory card or uploaded to the cloud. If it goes to a memory card, most cameras rewrite over existing files once full, so make sure you check footage regularly or risk losing it.

10 types of spy cameras that could be watching you now, #6 is shocking
Camera technology has advanced a lot the past few years. They keep getting smaller and smaller, making it possible to conceal them any which way.
Spy cam manufacturers have been creative in producing some of the most cleverly disguised (and tiny) camera/DVR systems, complete with HD video, motion detection, large storage card support and remote controls.
So here are 10 spy cameras you’d never expect!
USB flash drive spy cameras
These cameras look like your regular USB storage sticks, but think again. They have a hidden camera inside! It’s not unusual these days for someone to be carrying USB sticks around so spotting them can be a bit challenging.
Tech news that matters to you, daily
Privacy, security, the latest trends and the info you need to live your best digital life.
So how can you tell? The camera lens for these USB stick cameras is usually located on the posterior end of the stick, opposite the USB plug. With this form factor, this spy cam will blend seamlessly in an office or classroom.
The product shown here is a U-Disk Nanny Cam Video Recorder USB Flash Drive Hidden Camera from Amazon.
2. Men’s shower gel spy cameras
As creepy as it sounds, they actually sell these now. They’re cameras disguised as shampoo or body wash bottles. The top half of these sneaky little spy cams is actually a refillable container for legitimate shower gel and the bottom half houses the camera circuitry. They are also advertised as water-resistant, equipped with motion detection and a remote.
This type of spy cam makes sure it will record only what you want to record, but it’s also something you should watch out for when you’re staying at someone’s house, or in a rental.
The product shown here is an Adidas Men’s Shower Gel Bathroom Spy Camera from Mejo.com.
3. Wi-Fi AC adapter spy cameras
Now, these cameras are disguised as your regular power brick/AC power supply. They plug into the wall like any run-of-the-mill wall wart and they look unassuming enough to be mistaken for anything else. They even come with their own wire that apparently powers nothing. But they hide a deep, dark secret. They are actually fully functional camera/DVR systems.
The lens for this spy cam is usually hidden in a tiny hole between the + and – polarity symbols. Some models also have built-in Wi-Fi so you could live stream the footage to your phone or tablet via app as it happens. If live streaming is not your thing, it also saves on a Micro SD under a hidden compartment on the unit.
The product shown here is a Focuslife HD Hidden Home Security Surveillance Camera Nanny Camp P2P Wireless Spy Camera, available at Amazon.
4. Bathroom tissue box spy cameras
These spy cams look like normal tissue paper boxes or toilet roll dispensers but look again! Many manufacturers of some of these contraptions advertise them as pinhole free so they are harder to detect. They’re a bit bulkier than the other spy cams but blend seamlessly into a home setting. Just plop them down on a table or dresser and no one would suspect a thing.
The product shown here is a Tissue Box Portable Hidden Camera from Amazon.
5. Electrical outlet spy cameras
See that wall outlet face that almost always resembles a startled emoji? Well, it might just be a camera in disguise. The tiny cameras for these units are hidden within the normal electrical sockets’ holes.
The rechargeable ones have sticky adhesive backs so they could be positioned anywhere there is a wall to cling to. But other models actually plug in and go on top of an existing wall outlet.
The product shown here is a Spy-MAX security Products Hidden Camera Outlet from Amazon.
6. Toilet brush spy cameras
Who would ever think this lowly toilet sanitation device could be anything else? Well, no one… except the guys who thought of the toilet brush spy camera, of course. And there lies the charm of this little gizmo. Who would ever want to mess with a filthy toilet brush in a stranger’s house? Exactly.
Most of these units come with a remote control and motion detection, too, so covert surveillance is entirely possible with these deceptive little things. These spy cameras aren’t found in many of your typical retail stores, but there are online shops that are dedicated to selling them.
This product is the Pinhole Spy Toilet Brush from SpyCameraBathroom. com.
7. Smoke detector spy cameras
Smoke detectors may just be the perfect hiding spot for hidden cameras because they are usually installed higher up in a room (say, the ceiling). These smoke detector spy cams also use wide angle lenses and this, combined with elevated placement, could provide full room surveillance and maximum privacy invasion.
It’s important to note that most of these are not working smoke detectors. So, if you’re in a location that seems to have more smoke detectors than necessary, it may be a sign that some of them are hidden cameras.
This product is the PalmVID DVR PRO Smoke Detector Hidden Camera Spy Camera with Adjustable View from Amazon.
8. Clock radio spy cameras
These cameras come in different shapes and sizes and they do play media files and have FM radios built in. You won’t suspect a thing if you are jamming to your favorite tunes, right? Clock radios usually have busy user interfaces with knobs, labels and sensors so the pinhole lens for these spy cams will be harder to spot.
Some models can even shoot in low-light conditions and loop recordings on a large capacity micro SD card. This means that all-day, all-night coverage is certainly possible.
The product shown here is the Jumbl Mini Hidden Spy Camera Radio Clock from Amazon.
9. Cellphone charger spy cameras
Similar to the power adapter spy camera, this device is plugged in to the wall, pretending to be a regular USB charger. But it’s really a fully functional USB phone charger – with a few extras, like a mini camera and a fully functional DVR!
These types of spy cams actually do double as real chargers too, so they’re difficult to spot.
The product shown here is the Hidden Spy Camera 1080P HD USB Cube Surveillance Wall Charger Cam with Motion Detection at Amazon.
10. Sports shoes hidden spy camera
Sneakers are probably one of the last places you’d think to look for a spy camera, but these stealthy cameras exist. They look like regular shoes, but have a tiny camera embedded in one of the tongues. The camera points upward, giving the spy a bottom up perspective of the surroundings.
The product shown here is the Men Sports Shoes Pinhole Spy Camera from SpyCameraBathroom.com.
As you can see, spy cameras now come in the most unexpected forms! If you’re a bit wary that there may be incognito cameras around you, there are tools that could help you detect them. Click here to learn how to spot them now.

Floating sauna obscura in Finland – eFinland.com
22 august 2019
Reading time: 1 min
In Finland, there has recently been a fashion for an unusual sauna – an obscura sauna, which, among other things, is also floating! EFinland explains what it is.
Two ancient inventions in one
The essence of such a sauna is that it works not only as a sauna, but also as a camera obscura, that is, it gives an inverted all-round view inside itself.
Recall that the camera obscura was invented before our era and it is designed very simply: it is just a light-tight box with a small hole in one of the walls and a screen on the opposite wall.Rays of light pass through the hole and, depending on the focal length, create an inverted picture on the screen. We can say that the camera obscura is one of the earliest and most primitive photographic devices.
Photo: Yle / Rasmus Tåg
Finnish artist Heidi Lunabba, who had to work with photographic equipment for a long time, came up with the idea to combine two old inventions – a sauna and a camera obscura. Before that, Heidi, together with her friends, made a camera obscura in the form of a small house. The sauna was the next step. The result is a small miracle.
Inside and outside at the same time
The interior of the sauna serves as the very box on the walls of which the screen is placed. Well, so that there was something to see in the sauna obscura, Heidi made her floating! The idea is brilliant, because from the middle of a lake or bay the view is always wider than from someone’s yard. Well, since the walls and benches in the sauna are white, you can see everything very well.
Photo: Yle / Rasmus Tåg
Inside, the camera reflects the landscape outside.It turns out that you are, as it were, on the border between the inner and outer space. The wall of the sauna reflects the water and the coastline, while the paddle boat you sailed on sways from the ceiling. No wonder – everything should be upside down in the Obscura camera.
From Loviisa and back
Heidi Lunabba launched her brainchild into the water for the first time in her hometown of Loviisa, which is located on the seashore, or rather, on the shore of a small calm bay. It happened in 2004.
From Loviisa, the sauna traveled all over Finland: visited Vaasa, Kirkkonummi, Rauma, Raseborg, Helsinki, Turku and other places. Soon, her counterparts began to appear in different parts of the country. They are seen both in the north of the country and near the capital, in Espoo.

This year Heidi’s sauna obscura is swimming in his native Loviisa until the end of August. You can still have time to visit it. You just need to agree with Heidi. To do this, she needs to write to Heidi @ lunabba.com.
By the way, usually in Finnish saunas it is either forbidden to take pictures, or it is not accepted – photography is welcome in this sauna!

Film camera from Lego / Habr
I really like Lego constructor, cameras and programming. I decided to combine these three hobbies and build an automatic film camera from Lego. I wanted the camera to do everything by itself: all the user had to do was insert the film, aim at the target, and press a button.
In this post I would like to talk about how I made an automatic camera from Lego, how I programmed it and what came of it.
I started from the very beginning, with a pinhole camera. This is the basis of any camera: light enters the film (or sensor) through a hole and leaves an image there.I decided to make a hole in a piece of foil. With the help of one of the mini drills, I made a hole with a diameter of about 0.3 mm.
Now it was necessary to assemble an opaque camera, in which the film would be located. Calculators from Mr. Pinhole. They made it possible to calculate the optimal dimensions of the chamber. It’s very simple: with a hole size of 0.3 mm, the distance from the hole to the film should be somewhere around 60 mm.
The principle of operation is very simple: the user inserts a new film cassette, the film is immediately rewound onto a free reel.With each new frame, the tape is wound back into the cassette. When all the frames are snapped off, you just need to get the used cassette. Here are a couple of snapshots of the assembly process:
I wanted the pinhole camera to provide three interfaces: control of the main spool (which the user supplied), control of the free spool (where the film is unwound), and control of the shutter. It looks like this:
In the future, the motors of the automation module will turn these three gears. In the meantime, I needed to make sure the camera was blocking out light.I took my design to the darkroom. I decided to use photographic paper to find light holes. Photo paper is sensitive to light: where light hits, a black spot appears. I stuffed photographic paper into my camera obscura, brought it out into the light, waited a few minutes and developed the paper. The entire surface was covered with black scars. It took me several hours to find all the holes and cover them with duct tape. Here’s what happened:
The camera obscura was completed. To be honest, many amateurs assembled such devices themselves.So while I was on a relatively well-trodden path. However, I did not find a single amateur project that went further and decided to automate my camera.
I had Lego bricks as a child. However, the set
I bought only recently. The kit contains three motors, a pair of buttons, a light sensor and a programmable module. Everything you need for a modern camera.
The automation module should contain three motors – two for rewinding and one for controlling the shutter, – a release button, a light sensor and a sensor that determines if a pinhole camera is inserted.The last sensor is quite important: it is he who determines the moment when the camera is just inserted and it is necessary to unwind the film. It should have turned out something like this:
Specific details were constantly lacking. The BrickLink website came to the rescue. On it, I found absolutely all the details and was able to buy them through PayPal. It must be said that the prices were very reasonable. Soon the automation module was assembled. The camera obscura was neatly inserted into the automation module:
Iron, or rather, plastic was ready.It remains only to program this matter.
The programmable module (controller) is controlled by the operating system from Lego. The module can be programmed in a visual development environment: drag bricks-operators, make blocks-cycles, etc. I really did not like this shit. So, the first thing I did was flip the module with the Lejos system. Programs for it can be written in a somewhat truncated Java. What we need for our adventure.
I posted the camera code on http: // code.google.com/p/legocamera/.
The program contains several interesting features:
Logic for calculating the film rewinding angle
It turned out to be much more difficult to rewind the tape than it seemed to me at first. Film spools are very similar to a spiral. That is, the angle to which the spool must be turned to wind 40mm of film depends on the amount of film already wound. To make the calculation, I had to use an equation of the second order. You don’t code that every day. Who cares to see – the logic in the file
Calculation of valve speed
And then a trap awaited: the Lego sensor returns the illumination level with a number from 0 to 1023. I was not able to find out how this number relates to any physical values. So I had to build a correspondence using the scientific poke method. I rented a light meter and went for a walk. I took a measurement with a Lego sensor, wrote down the reading, then measured it with a device. The result is a fairly passable correspondence table. It seems to me that it can be clarified, but it will do for beta.Who cares to see – welcome to
I really wanted to dynamically update the information about the camera: whether a pinhole camera was inserted, the exposure meter value, the number of frames, the current task, etc. Additional thread, a little magic, and, it seems to me, it turned out almost like an adult:
Everything was ready. Here is a video demonstrating how the camera works:
And here are the resulting photos.Hydrant:
I will continue to shoot with my camera: it’s so simple, I press the button – and you’re done!
Camara Obscura – DEVice KIngdoms
Camara pinhole (lat. Camara obscūra – “seòmar dorcha”) – an seòrsa inneal as sìmplidh a leigeas leat ìomhaigh optigeach de nithean fhaighinn.
Is e bogsa teann aotrom a th ‘ann le toll ann an aon de na ballachan agus scrion (glainne reothadh no pàipear tana geal) air a’ bhalla mu choinneimh.Bidh ghathan solais a ’dol tro tholl beag (tha an trast-thomhas aige an urra ri“ fad fòcas ”a’ chamara, timcheall air 0.1-5 mm), a ’cruthachadh ìomhaigh invert air an sgrion.
Air bunait a ‘chamara obscura, chaidh cuid de chamarathan a dhèanamh, ris an canar Stenop.
Tha camara toll-giuthais na chùis shònraichte de dh ’inneal le fosgladh còdaidh.
Air sgàth nach eil eileamaidean optigeach ann an camara toll-giuthais a bheir buaidh dhìreach air solas (ach a-mhàin oir an toll), tha e freagarrach airson ìomhaighean a chruthachadh ann an linnean làn.
Chan urrainn dha camara toll a bhith a ‘toirt ìomhaigh àrd don ìomhaigh. Nuair a lùghdaicheas trast-thomhas an toll, chan eil an ìre biorach a ‘dol ach gu ìre shònraichte, ma tha an toll ro bheag, bidh buaidh sgaoilidh solais air an toll a’ tòiseachadh a ‘toirt buaidh an geom chan eì …
Tha am pròiseas airson ìomhaigh a shoilleireachadh na dhearbhadh matamataigeach. Tha an ìomhaigh air an sgrion na dhearbhadh dà-thaobhach den nì a tha san dealbh le àite sgapte de stòr solais puing (eng.gnìomh sgaoileadh puing), tha cumadh ìomhaigh stòr solais puing ann an cùis optics geoimeatrach a ’co-fhreagairt ri cumadh leudaichte an toll (ma nì sinn dearmad air eadar-dhealachadh agile sgaraidhean e Mar eisimpleir, ma tha an toll ann an cruth slit, an uairsin bidh ìomhaigh stòr puing mar loidhne dhìreach agus bidh ìomhaigh an t-seallaidh neo-shoilleir loidhneach; ma nì thu grunn thuill, thèid an ìomhaigh “iomadachadh” (faic cuideachd Encode Aperture).
Tha Obscura air a chomharrachadh le doimhneachd mòr neo-chrìochnach.Tha e comasach bruidhinn mu fhad fòcas an toll-giuthais a-mhàin le cumhachan. Mar as trice thathas a ‘tuigsinn an fhaid fòcas co-ionann de chamara mar an astar bhon toll chun sgrion. f … Co-mheas f / D. canar, mar anns an lens, an àireamh-F. Camara le f = 100 mm agus trast-thomhas toll D = Tha luach fosglaidh f / 0.5 aig 200 mm. Tha àrdachadh an fhosglaidh (fosgladh) gu 1mm (dà stad) a ’lughdachadh na h-àireimh gu f / 100. Mar sin tha an ùine nochdaidh air a lùghdachadh gu 25 latha.
Bha a ‘chiad camarathan toll-giuthais nan seòmraichean dorcha (no bogsaichean mòra) le toll ann an aon de na ballachan. Thathas a ‘toirt iomradh air an obscura camara cho tràth ris a’ XNUMXmh-XNUMXmh linn RC. e. – thug luchd-leantainn an fheallsanaiche Sìneach Mo-tzu (Moists) cunntas air coltas ìomhaigh invert air balla seòmar dorcha. Is dòcha gu bheil iomradh air obscura camara ri fhaighinn ann an Aristotle, a bha a ’faighneachd ciamar a dh’ fhaodadh ìomhaigh cruinn den Ghrèin èirigh nuair a tha e a ’deàrrsadh tro tholl ceàrnagach.
Anns an linn XI, chleachd an neach-saidheans Arabach Ibn al-Haytham (Alhazen) à Basra teantaichean sònraichte gus sùil a thoirt air eclipses na grèine. A ’faighinn eòlas air cho cronail’ s a tha e sùil a thoirt air a ’ghrèin leis an t-sùil rùisgte, rinn e toll beag ann an canopy a’ teanta agus rinn e sgrùdadh air ìomhaighean naèine choine muin ’im bhalla. B ’e Alhazen a’ chiad fhear a mhìnich prionnsapal an obscura camara, stèidhichte air prionnsapal iomadachadh solais dìreach.Aig an aon àm, cho-dhùin e nach eil an teòiridh ris an robhar a ‘gabhail san fharsaingeachd mu iomadachadh solais anns na bliadhnaichean sin (a rèir dè na ghathan solais a’ tighinn bho na sùilean agus, “mar gum ‘ faireachdainn ”an nì) nach eil a ‘freagairt ri fìrinn.
Anns na meadhan-aoisean, chaidh an obscura camara a chleachdadh a-rithist agus a-rithist airson beachdan speurail. Mar sin, anns an XNUMXmh linn, chleachd am feallsanaiche Sasannach Roger Bacon agus an speuradair Frangach Guillaume de Saint-Cloud e gus sùil a thoirt air eclipses grèine, chleachd speuradairean XNUMXmh linn Levi ben cam gershom-agus ceàrnach na h-Alba a thomhas. a ‘ghrian (Levi ben Gershom – cuideachd planaidean).
A rèir coltais, b ’esan a’ chiad fhear a chleachd obscura camara airson sgeidsichean bho bheatha le Leonardo da Vinci. Thug e cunntas mionaideach air cuideachd anns an Treatise on Painting aige. Ann an 1686, dhealbhaich Johann Zahn camara obscura so-ghiùlain le sgàthan 45 ° a dhealbh ìomhaigh air a ’bhalla chòmhnard as àirde ann am bogsa. Chaidh am pàipear a chuir gu còmhnard air uinneag glainne sa bhalla, agus cha deach an ìomhaigh air a thionndadh bun os cionn, a ’dèanamh dealbh nas fhasa.
Chleachd cuid de luchd-ealain (mar eisimpleir, Vermeer) obscura camara gus an cuid obrach a chruthachadh – cruthan-tìre, dealbhan, sgeidsichean làitheil. B’e bogsaichean mòra a bh ‘ann an camarathan obscura aig na h-amannan sin le siostam de sgathanan airson solas a leigeil seachad.
Tha Isaac Newton anns a ‘chlàr aige’ Optics ‘a’ toirt cunntas air prionnsapal obrachaidh uidheamachd coltach ri obscura camara, ach le inneal eadar-dhealaichte.
Anns an Ruis, ann am meadhan an XNUMXmh linn, bha an obscura camara, ris an canar “colossus airson dealbhan a thogail,” farsaing.Shoirbhich leis an fhideag Makhaev, le cuideachadh bhon “colossus airson toirt air falbh ro-shealladh St. Petersburg”, a rinn am preantas de “ealain ionnsramaid” Tiryutin ann an seòmar ionnsramaid St. bailtean-mòra Ruiseanach eile.
Gu tric, an àite toll sìmplidh, chaidh lionsa (mar as trice aon lionsa) a chleachdadh, a mheudaich gu mòr soilleireachd agus soilleireachd an ìomhaigh. Le leasachadh optics, dh ’fhàs lionsan nas toinnte, agus às deidh innleachdas stuthan a bha mothachail air solas, thàinig camarathan toll-giuthais gu bhith nan ciad chamarathan.
Ach, eadhon a-nis bidh cuid de dhealbhadairean a ’cleachdadh na“ stenoops ”ris an canar – camarathan le fosgladh beag an àite lionsa. Tha ìomhaighean a chaidh an glacadh le camarathan mar sin air an aithneachadh le pàtran bog sònraichte, sealladh sreathach air leth agus doimhneachd achaidh gu math mòr.
Anns an àm ro-dhealbh, chaidh camara-lucida a chleachdadh cuideachd, a chaidh a chruthachadh ann an 1807 leis an eòlaiche fiosaig Sasannach Wollaston – priosam ceithir-thahobhach, aig ceighàrn de sòothra sheìrì -tìre le duilleag pàipeir air a tha sgeidse air a dhèanamh.
