The PoC connector on the rear of the injectors provides a maximum voltage of 23V DC to the camera and also received video signals.
Ensure that all coax cables use are to a high enough standard to support high-voltage power and video signals. The slightest wiring mistake may indirectly cause damage to the camera, PoC injector and other connected equipment.
Also misuse/low grade cables may cause fire and other accidents. Please ensure care is taken.
When installing, make sure that all coaxial cables are specifically labelled with clear marker signs so that cameras video cable and the PoC injector cables cannot be confused.
Always be careful to check the wiring to avoid mistakes.
