I have just bought a 1080p Annke 8 channel DVR with some cameras. Inside the box is the camera PSU, a four way splitter, extension cables, and then the cameras.
But there is also four others little units/boxes that have a male and female barrel jack on either end and appear to fit inline on the power cable of each camera. But what the hell are they?
My mate thinks they might be a battery backup but they feel very light and don’t feel like they’d have enough cell batteries to make up the power to anything that the camera would need.
I thought it might be some sort of noise filter like this...
Anyone know for sure? And then do you know which end to fit it? Camera, DVR end or don’t matter?
