ATTENTION: 

It is recommended to connect the camera to the NVR or an external PoE 

switch. If using a DC power adapter (not included) with the camera, a 

REGULATED power supply is REQUIRED for use with this camera. Use of 

a non-regulated, non-conforming power supply can damage this product 

and voids the warranty.

• You can use a RJ45 coupler or switch (not included) to connect male 

ends of Ethernet cable together.

• To extend the cable run beyond 300ft (92m), a switch will be required 

(sold separately).

• Read this guide carefully and keep it for future reference.

• Follow all instructions for safe use of the product and handle with care.

• Use the camera within given temperature, humidity and voltage levels noted in the 

camera’s specifications.

• Do not disassemble the camera.

• Do not point the camera directly towards the sun or a source of intense light.

chemical-based cleaners.
