Video Anti-interference Device /Video camera Jammer( Video Anti-jamming Device )
Function
Video Anti-interference Device keeps video signals from strong electromagnetic interference during video transmission, to ensure video signals transmitted to be true, stable, clear and without distortion. It helps effectively solve the problems of image floating, distortion, ghosting, etc..
Features
- Keep video signals from external electromagnetic interference by adjusting signal frequencies;
- High level of integration, small in size;
- SMT Integrated Circuit, low power consumption, use 12V power supply as cameras do;
- of Aluminum Alloy Shell, durable and good at heat dissipation;
- Lengthen the transmission distance up to 1.2km.
Application Fields
Around elevators, electric motors, high-tension electricity lines, production lines, radio launching towers, frequency conversion equipments, other strong interfering environments, etc.
