Sunba IP Network Camera: Underpower Issue

Typical Symptoms 

A. Camera reboots repetitively during night time with the following cycle:

low light environment detected -> infrared on -> not enough power -> reboot -> low light environment detected -> infrared on -> not enough power -> reboot …… (cycling)

B. Camera panning by itself without gaining control over PTZ.

Why will this happen? 

A. PoE Camera

Wrong PoE+ Injector: The PoE injector/switch must be able to deliver at least 30W for an individual port! Must be 802.3at standard but NOT 802.3af, which is for bullet camera and can only deliver 15.4W.

Long Distance of Travel: PoE will also drop power along the Ethernet cable. If you are using a 300 ft long Ethernet cable, you may be at risk. Please try using the Ethernet cable less than 200 ft. The maximum travel distance also depends on the quality of the cable but generally it should not exceed 200 ft for the 30W power. If you increase the distance, the corresponding watts of the injector should increase as well to 48W or 60W.

B. Non-PoE Camera:

Long Distance of Travel with thin AWG power extension cord.

For over 50 ft of travel distance, please try using the AWG 18 standard or thicker (the smaller the AWG, the thicker the wire).

A quick test to perform is to plug the camera directly to the wall power (for power adapter) without any forms of extension.
