October 12, 20223 yr Hello Been lurking here for a while. I'm wondering if anyone has a solution for ip cameras and a 48v switch to get through loadshedding. There's many mounted on poles around my complex Thanks
October 14, 20223 yr Cameras directly you can power using some of the 48v POE capable Micro-UPSes that Uniterm Direct sells https://shop.dbg.co.za/mups45w8-8ahg.html

October 15, 20223 yr I came across this site. They have a 48V DC Mini UPS which could help to power your switch and IP Cameras. They also have some case studies which give different scenarios which might also give you an indication of run time dependent on load. https://tech-buddies.co.za/

Thanks. I missed the 2nd last point and only read the last feature which only lists a 12V and 48V output.

Will read up on them. Would be good if they have replaceable batteries though.
