"RAVEN" - A DEVICE FOR DETECTING HIDDEN VIDEO CAMERAS
Designed to quickly detect and locate hidden (camouflaged in various interior items and clothing) micro-video cameras, including those with "Pin-hole" lenses.
Designed to quickly detect and locate hidden (camouflaged in various interior items and clothing) micro-video cameras, including those with "Pin-hole" lenses.
The principle of detecting video cameras is based on the effect of retroreflection or "reverse glare", when a beam from a light source located on the optical axis of the video camera is reflected by the lens and the photodetector of the video camera, like a mirror, and is directed back to the light source. Therefore, if a hidden target is detected, a bright spot of red color is observed in the field of view of the device (reflection from the camera lens).
The detection range of Pin-Hole hidden camera lenses (ø 1 mm) ranges from 1 to 20 meters, depending on the application conditions.
"RAVEN" uses LED illumination of targets, which guarantees the safety of operation and the absence of harmful effects on humans (unlike laser illumination).
The operation of the device in the optical, rather than radio frequency range, allows you to detect any optical devices (including video cameras), regardless of their state (on/off) and the type of information transmission (via radio channel or cable). Radio-electronic interference, electromagnetic shielding, masking nets and lens hoods also do not prevent the detection of video cameras.
The technical solutions used in the device (the prismatic wrapping system" with a roof " Roof prism and multi-layer illumination of all optics) made it possible to develop a compact design with excellent optical characteristics, including high magnification, a wide field of view and exceptionally high image quality, which can significantly increase the speed of inspection of the room and reduce the likelihood of missing the target.
A high-efficiency switching power supply provides a long - term operation of the device from a single publicly available and cheap alkaline element of the standard size " AA " with a voltage of 1.5 V.
"RAVEN" is placed in a strong and comfortable case made of light aluminum alloys with a wrist strap and a soft rubber eyecup.
The device is extremely easy to operate, no special professional knowledge is required for its use.
