OKA-1/C - Flameproof digital camera
The OKA-1 / C flameproof digital camera is designed for real-time color video transmission and recording. The transmission of the optical fiber digital video signal is based on a Ethernet 100Base-FX protocol. The construction of mechanical connections (number of inlets) and the communication protocol (built-in Ethernet switch) enable cascade connection of subsequent cameras. The transmission of the analog video signal can take place via a coaxial cable, a symmetrical cable (copper twisted pair), optical fiber cable. The camera is equipped with a lens with an automatically adjusted iris. Additionally, the camera is equipped with its own IRLED light source to ensure work in areas without an external light source. The use of the power supply enables power supply from 42VAC, 127VAC and 230VAC. It has a 32x zoom function (adjustable remotely) for finetuning the focus in difficult lighting conditions. IN-built SD card slot enables recording of a real-time image.
