Need some assistance please.
Complex has cameras at different locations and we are looking at some options to power them during outages. Eskom’s new truck is they claim to have 2.5 hour outages but these generally last much more than that.
So the NVR sits in the guardhouse but the problem is link to the cameras around the complex is over fiber and then there’s an Ont in each pole box with a poe switch and then 2 cameras. Poe runs off 48-57v so those router backup things will not work. It’s on a pole so there’s the space / weight limit. Cameras require around 7-10 w so that’s a total of 20w. Switch should use another 10-20w max including the Ont.
Any ideas for a cheap and efficient solution?
I was thinking of using some old 105A lead acid batteries but can’t find anything to mount these onto the pole and then there’s an inverter / charger that also needs to go somewhere.
