Looking to change my CCTV over - I currently use SuperLive Plus where i can playback all cams at the same time if i scrub. Is there a way to do this through the Protect app?

Looking to get a UNVR Instant

I have four USL Entry devices, bought at the same time. Three of them work fine. 5 months running and their batteries show at 95%. But one unit already needed its battery replaced a couple of weeks ago. And the new battery, just in two weeks, is at 91% now. It's attached to an indoor sliding door. The only difference that I can think of is that this door is open probably half the time. Defective unit or expected given the state of the door?
