Frequently Loosing Signal

Maybe my answer wasn't clear but

  • I did connect the camera with a short 3' cable to the PoE switch (and I also tried a non PoE switch with a PoE injector)
  • I did a hard reset on the cam. I know it worked because the IP changed back to 192.168.1.108
  • I have no other device at .108. I checked the device list in my router before resetting the cam. Plus this is in my static IP pool and I have a list of all devices with a static IP. There is none with .108. Also arp -g reports the correct MAC address.
  • I initialized the cam with the ConfigTool
  • IP = 192.168.1.108, subnet = 255.255.255.0 (which matches with my router), Gateway = 192.168.1.1 (which is my router).
  • In the ConfigTool I hit refresh. Even after waiting for a while, quite often the camera doesn't show up. I have one other non-Dahua camera showing up consistently. That one is on a different IP address.
  • I closed the ConfigTool, opened Edge and entered 192.168.1.108. Sometimes the web portal doesn't pull up, sometimes it does. But it always just shows the rotating circle for Main Stream, Sub Stream 1 and Sub Stream 2,

The reason I mentioned BI is just to check another program besides ConfigTool to see how that behaves. But it's consistent, i.e. sometimes when setting up a new cam it sees the cam, sometimes it doesn't. I did do that about 3-4 times without actually adding the camera. After that I added it incl. entering the user=admin, pwd=my new password set in ConfigTool. The camera showed up as generic. I tried that first and then also changed it to all options of Empire and all options of Dahua, Nothing gave me an image.

Now maybe some of my settings in BI are wrong but the point is that even with a camera set to factory settings ConfigTool only sees the came sometimes, the web portal only comes up sometimes and when I get in the web portal using Edge I never see a video signal. That same behavior was observed both at the location where my old Hikvision camera used to be (which I now installed again) and with a short cable to my PoE switch and a two short cables using my non PoE switch with a PoE injector I bought.
 
Well it is possible that you have a bad cam. While it is rarely reported here that a Dahua or Hik cam is bad, it could happen. I don't know how many cams Andy sells, especially of that model, hundreds? I suggest you contact him about this if you bought it from him.

PS Have you any other Dahua cams that work?
 
This is my first Dahua cam. I want to replace my HikVision cams with better ones so I was trying out this Dahua. My HikVision cams were easy and quick to set up.
 
What exact model # of cam?
With the camera connected with a short premade cable to a switch, reset the camera to factory defaults once again.
Once it boots back up, open IE, not edge, Internet Explorer.
Point IE to the 192.168.1.108 address.
See if you get a prompt to initialize the camera. Follow the prompts.
When it asks to download the plugin, do so.

I reason I mention this, I just started a review of a new Dahua cam, and the IPconfig current version of IP config will NOT intialize the new cam. But using IE it initialize's fine. Also, I have 11 Dahua cams, the IP config tool is now only finding 5 of them. When it used to find them all no problem.

This did get me a little bit further but I am still having issues. When I used IE to set the time of the cam as part of the first log in I got the error "Save config failed!". It worked the second time. Then I installed the IE plugin. However, on the main stream I am getting "Resource is limited, open video failed!". I closed all IE instances/tabs and tried again with the same resource error. I did shut down BI as this one uses quite a bit of resources on my PC but even after that when CPU time was about 10-15% and memory about 35% I still got the same error.
 
FWIW I dont use the Config tool regardless of whether I'm using a PoE NVR or regular Non-switch NVR or stand alone camera.

I simply plug the camera into the same network as my laptop, hit the web GUI at 192.168.1.108 and activate it by the prompts the camera takes you through. Time zone, date, where you want P2P or Automatic udates, and log in. Takes 60 seconds.

Clear the IE cache files.
Restart the computer.
What else do you have running on that computer.
Again, what model camera are you working with?
What processor do you have in that computer?

I don't either for my own cams, but I at least try it with the test cams.

The Resource limited I get a lot with various IE versions.

Try Pale Moon

And really try SmartPSS. Once you have the camera activated, I use SmartPSS to view. I have alwyas had problems with the live view on any given browser any given day, on any given camera firmware.

I've stuck with Chrome with the IE tab extension installed, and rarely have any issue. YMMV

I have never been able to get SmartPSS to find a cam. I must be doing something wrong.

I've never used auto search. I just add the camera or NVR manually using the "Add" link.

NOTE: I dont use SmartPSS as a VMS. I dont even install the VMS portion I just use it as a viewer and for downloading footage. Works great across many different Dahua NVR's and every one of the Dahua cameras Ive installed. I'm looking at 36 from 5 different NVR's right now, 4 remote.

It's a EmpireTech IPC-T5442T-ZE. I cleared the cache and restarted the computer. Then I used IE to get to the camera. The first two time didn't work. The third time I got to the web portal. I still got the same error. Also with Edge. My computer is a i7-9700K with 32GB of RAM, 2TB SSD and running Win 10 with the latest updates installed. After restarting only a few programs are running (they automatically start). Used CPU time is between 12-20% with IE using about half of that.
 
I downloaded SmartPSS and added my camera. For the first minute it showed the camera is offline. Then it came online. I wanted to look at the live feed but after a while SmartPSS said the camera is offline. But even when the camera shows online I can't see any live feed.
 
Is this camera on the same local network as the machine running SmartPSS?

I would take every piece of equipment out of the equation. Connect the camera to a port on your router. Assume its DHCP and the IP of the camera would remain 192.168.1.108 and try reaching it directly in a browser and/or smartpss. If it still does it, its a bad camera.
 
The camera is on the same network (at some point I will put them on a VLAN, just didn't get around doing it yet). I tried two different switches and it didn't work with either of them.
 
I returned the cam today. My HikVision cams just take a few minutes to set up. I spent so many hours on this EmpireTech/Dahua cam including spending money on a PoE injector just to check if my PoE switch is at fault.
 
I’ve bought and installed well over 100 Dahua cameras and a dozen NVRs. They too just take a few minutes to setup. Not had any problems (other than firmware feature issues now and then). Sorry we werent able to figure out your problem.
