My 4216P NVR has, for the past few years, displayed all 10 cameras (stream S1) on the monitor. But recently one of the camera windows is blank unless I switch the stream to Main. I've fiddled with lots of settings but I'm at a loss to the reason why. I'm sure it's something sinmple. Any...

I can access my NVR web GUI remotely via OpenVPN on my TP Link modem at home and OpenVPN on my laptop (and MS Edge) when I'm away from home. I can view live footage and playback videos but I cannot see how to get a copy of a video clip. So for example, If I'm away from home, use my laptop to...

I have Dahau gear for home but would like to install a 12V system on my motorhome. I figure 8 cameras to cover the outside perimeter and NVR to record and provide intruder alerts. A couple of experiences when remote camping have highlighted the need so I'm keen for suggestions. A 12V system...

I run the same version of Smartpss on two laptops. Both laptops access the same NVR via WIFI. The Smartpss config settings on both laptops are identical. Smartpss on both laptops used to work correctly up until 2 days ago. At that time Smartpss on laptop B suddenly stopped working so I...

In my home office I use a monitor and mouse connected directly to the NVR (a 4216-16P) to manage my CCTV system. It works well for my needs but I need to setup a second location about 10m away (in a separate room) to do the same thing. Can I somehow run a second monitor and second mouse in this...

I use OpenVPN and DMSS on my Samsung android 'phone to remotely (and hopefully securely) view cameras and get intruder alerts via my Dahua 4216 NVR. This system has worked well since I installed it about 1 1/2 years ago. A few days ago DMSS opens but won't allow me to proceed past the home page...

Having trouble locating a <AU$1,000 UPS in Australia that can act as a 24hr backup for my Dahua NVR and cameras. I figure 24 hrs maintaining about 100W would address our infrequent but lengthy power outages. It seems UPSs are only designed to maintain power for a few minutes to allow controlled...

I'm having a lot of trouble getting this camera to set off an intrusion alarm at a 40m range at night. Daytime intrusion detection at this range, and further, works well. The onboard IR is supposed to be good for 50m (yes I know it is probably overstated). Even if I supplement this with a 18W...

I use this camera to monitor some sheds about 50m away. I've zoomed in a little and set the intrusion zone around the perimeter. Daytime intrusion alarms work fine but at night there is too much ghosting of the image for the alarm to function. Bit rate is set at the highest (8192 for mainstream...

I keep my NVR and cameras on a stand alone network. My Dahua 4216 16 PoE port NVR NIC is 192.168.2.108 with gateway 192.168.2.1. The NVR is connected to a 4G wireless modem/router. Several Dahua cameras are connected directly into the PoE ports and the NVR automatically assigned them IPs in the...

The buzzer on my Dahua NVR4216-16P-4KS2 sounds exactly like a local bird so I never know whether its an alarm event on the NVR that has just sounded or if it is a bird. How can I replace the default buzzer (which is more like a "beep, beep") with something more distinct. I can turn the alarm...

At home I have a Dahua 4216-16P NVR, cabled to a TP Link 4G mobile broadband modem, a static/fixed IP address for the modem and running OpenVPN on the modem. Only the NVR is on this mini network. I have OpenVPN installed on my laptop and I can connect to my home NVR with my laptop from outside...

I have eight HDW3641 2.8mm cameras surrounding my house which seem to do a good job of detecting people (I use IVS "intrusion" settings) any closer than 20m to the house. Now I'd like to install a camera on my house which can observe a person snooping around my shed which is 40m away from the...

A couple of queries from a newbie: (1) after I've finished experimenting with camera setups, recording, etc I'd like to delete all the test video clips prior to going "live" so to speak. How can I do this in SmartPSS or the NVR interface? (2) I can locate the camera "overlay" options in the NVR...

Couldn't find anything in the 4216-16P NVR manual I downloaded from Dahua. I'm wondering if in my case it would be easier to mount the NVR vertically against a wall. Air circulation would probably be better but the HDD may not like being vertical. I could also more securely bolt the NVR to the...

Hi all, some newbie questions to get me off to a fast start. I've read dozens of pages but confusion has set in. I'll stick with POE Dahua gear I think and recording to a Dahua NVR in the house. My needs: One camera looking at front of house from 30m away, FOV about 120 degrees, can ID a face...
