Hi, i'm interested i securing my flat. After buy and try with some cheap and easy DVR / NVR i bought DAHUA 5216-4KS2 (V1?).
I added an DAHUA ARB1606 (AlarmBox). First it worked fine but due to some loose contacts during installation i destroyed the RS485 input chip? from the NVR,
the alarm box (even an additional buyed one) will not berecognized any more.
Now i buyed a additional NVR 5208-4KS2 (V1) with low Firmware version, no alarm boxes!!
