Four versions
, with different output video signals:
- KTi-3 composite video output
- KTi-3m composite video output and TV modulator
- KTi-3sw composite video output and multimode,
fibre-optic output
- KTi-3sj composite video output and single-mode,
fibre-optic output.

Intrinsically safe CCTV camera used for real-time colour video transmitting from methane and/or coal-dust explosion-risk areas, through various transmitting media, to surface or underground video viewing stations.
The "composite video" output is used for transmission via an unbalanced concentric 75Ω line or balanced 110Ω impedance line (twisted pair).
The KTi-3m camera is equipped with a modulator, so the image can be transferred on separated channels in the frequency range from 25MHz to 120MHz.

The KTi-3msw and KTi-3sj versions are adapted to connect with fibre-optics. Depending on the version, the image can be transmitted over a distance from several hundred meters to several kilometres.

The camera has a lens with automatically adjustable aperture depending on light intensity. At very low light intensities the sensor automatically switches to black and white.

All connections of electrical signals (power, "composite video" signal) are located on the camera's body via connectors with screw clamps. The "composite video" signal can also be connected via hermetic BNC connectors on the camera's body (custom made). The optical fibre enters the socket inside the body through the M16 or M20 cable gland.
