Hi group, I'm after some advice on a replacement psu for my swann cctv unit (SRNVR-87285H) its a 48v 2a power supply which I've already replaced twice in less than 2 years (3rd party ones purchased from amazon). the original one lasted 5 years so I'm wondering is there a manufacturer out there that sells reliable high quality ones not cheap rubbish available online that i can only find so far. Swann isn't interested in any after sales support, any help would be appreciated. il upload a picture of the last one that failed.
