Application Scope of IP camera surge protector
For the AC220V, AC24V and DC12V power supply HD security camera/ CCTV camera/ IP camera, and it’s transmission lightning protection is suitable for the RJ45 connector net work.
Brief Introduction of CCTV & CATV
DK-DW/m Two in One Combined Surge Protective Device is designed according to IEC standard. It is easy installation, simple maintenance and can work stably under severe environment.
It is suitable for HD security camera, CCTV camera and IP camera. Installed in the fore-end of the cameras, it can protect them from the permanent damage or wink out caused by induced over-voltage, over current, and other induced surge voltage.

Installation and Cautions of lightning and surge protection
1) Connected this SPD in series between the circuit and the equipment.
2) Adopt connecting terminal as the power connector, RJ45 as the signal connector. Input terminal connect with the power and signal line. Output terminal connect with the equipment connector.
3) Grounding connection terminal connect the grounding line, and it shall connected firmly. The Grounding line shall be as short and thick as possible (the sectional surface shall be no less than 4 square mm) . And the earth impedance shall less than 10Ω. Please pay attention to check the grounding system to avoid the SPD loss protection function because of the open circuit or too high earth impedance.
