Safety precautions:
a) When the SPD box is installed in final system, it must achieve all the requirements of GB4943 (EN60950, IEC60950) standard;
b) The equipment has to be installed by authorized professional person, before installation, to cut off power supply,
and prohibit hot-line work from accidents
Function and theory
AJ3 type 3 in 1 surveillance SPD, integrated by Power SPD, video signal SPD and control signal SPD, is used to
protect surveillance system sensitive to electromagnetic interference, from damaging by lightning induced voltage,
power interference and electrostatic discharge.
Application
1) The device (power cable, PTZ cable, video cable) of surveillance system
2) Bank surveillance system and housing district safety system
3) School, enterprise and road safety protection
