I need help with truvision NVR 21S

Recommended Posts

I bought a Truvision DVR from a local thrift store, I was trying to swap a 1TB WD Purple Hard Drive with a 512GB Seagate drive. When I try to bang the front panel to put it back, it triggers an alarm, can anyone figure out a solution to this problem?

Yes, because I can only seen the unit with no cameras in the thrift store.

Is the unit beeping but is running…. As in you can see the menu screen
