Hi all, I am looking to get 4 of the new Dahua TIOC version 2.0 cameras (DH-IPC-HDW3849HP-AS-PV-0280B-S3) and pairing it with a basic 4ch NVR (NVR4104HS-p-4KS2). The shop tells me while the NVR4104HS-p-4KS2 supports receiving notification and viewing live footage and replay from mobile phone on DMSS, it does not support arming or disarming. If I want to arm or disarm from phone I need to upgrade to the pro version of the NVR. Is this correct? I have been searching online but can't find anywhere that says anything about that. Hoping one of you knowledgeable people can shed a little light on this. Thanks!
