Using such homemade You can secretly record video and sound. This will be possible thanks to a miniature camera and microphone, which are built into sunglasses. To buy such glasses in the store, you have to give an amount of about $ 300, so it makes sense to tinker a bit and collect spy glasses do it yourself.
In the video below you can see how such glasses work in practice.
Brief characteristics of the device:
The camera has a resolution: 380 TV Lines
Used Video System: NTSC
Minimum Illumination Level: 2 LUX
Total effective pixels: 510x492
The camera has a viewing angle: 30-35 degrees
You can shoot at a distance of 50 mm and infinitely far
The camera shoots without delay, in real time.
There is an automatic iris, as well as an adjustable focus.
A 9V battery or an adapter with parameters AC 220 V-DC> 8 V 200 mA can act as a power source.
With a good battery, the camera can take up to 10 hours.
Materials and tools for assembling homemade products:
1. First of all, you need a good miniature camera, which has the ability to record video. Such a camera can be bought on the Internet, for example. A connector for a “Krona” battery is also included with such a camera.
2. The power source. Battery "Krone".
3. Polarized sunglasses.
4. Now about the tools. Here you will need a soldering station, a glue gun, heat shrink, scissors or another tool for stripping the insulation on the wires.
Getting started with spy glasses
Step one. Start with wires
First of all, you need to figure out how to connect the camera and microphone. To do this, remove the insulation from the cable, the author's cable consists of four wires. Video is transmitted through one wire, one sound at a time, and the other two are needed for power, that is, grounding and plus. At the end of the cable is a connector type "tulip".
The author cut the wire from the camera, deviating from it a distance of 10 cm. It is important to remember that the length of the wires on the cut cable must be such that they can be soldered.
Once the wires are sorted out, they now need to be lengthened. For such purposes, a cable length of approximately 1 meter will be required. Instead of a cable, the author used separate wires. The joints must be soldered so that the contact is reliable. After this, the solders are insulated with a heat shrink tube at both ends. The wires must be of different colors or they must be marked so as not to be mixed up later.
Step Two Preparing glasses and installing the camera
Now you can start installing the camera in glasses. It all depends on how much space is inside the glasses. The larger it is, the easier and more inconspicuous you can install the camera. To install the camera, the author uses a glue gun. Before sticking the camera, the glass of the glasses must be thoroughly wiped, as there will no longer be access here.
Step Three The final stage. Connect glasses to the camcorder
To covertly conduct wires, you need a shrink tubing. She puts on the temple of the glasses, and the wire extends from the inside. Well, then you only need to connect the camera with glasses to the camcorder to record video. This is done using connectors.
For such purposes, the author used the Sony DCR-H32 camcorder. It is great in size, has an AV input, and also records on MiniDV.
To hide the wires, they need to be stretched along the back of the neck, then a shirt is put on top. Well, the wire itself under the shirt goes into the pants pocket. After connecting the connector and the 9V power supply, you can proceed to covert video shooting.
Despite the simplicity and low cost, video and sound are recorded pretty well. As an addition to this scheme, you can also connect a lapel microphone that attaches to clothing. According to the author, this home-made cost him only $ 40.
