2 cameras are showing in SADP but only one has video

[tonie]

Hi, I would appreciate if someone could help me out.

I connected 2 cameras and SADP detected them both, but I only get video from one of them.
Edit: Now no video on both cameras.

This is my NVR Camera Management screen:

This one is my SADP:

Faulty cabling is a common cause of being unable to stream video.
SADP only needs a handful of packets to figure out a device. Video streaming needs reliable communications for a few thousand packets per second.
Suggestion:
If feasible, try hooking the camera up with a short, pre-made length of cable.

Thanks. I did and no avail. I don't think it's the cable because they all used to work when I tested them.

The .9 camera has an incorrect default gateway.
And is the .3 camera connected in to channel 15?

*edit* And the POE interface IP address at .99 has been changed - should usually be .1 if it's to be referenced as a default gateway.

192.168.254.9 has ccch. In its serial number indicates it’s a full Chinese camera v 5.2.5 is this causing you a language miss match issues?
Alastair will be able to point you in the right direction to fix that

What do you mean it has incorrect default gateway? What should it be?
.3 camera isn't connected to channel 15. I can't seem to delete all the inactive cameras.

These are Chinese cameras but all of them are in english so no language miss match issue.

I can't just get these to work even though they did.

I can't seem to delete all the inactive cameras.

That's because they are pre-defined and fixed - each one is associated with a POE channel.

What do you mean it has incorrect default gateway? What should it be?

The .9 camera has it's own IP address (.9) as it's default gateway.

.3 camera isn't connected to channel 15.

But you've got the .3 address assigned to channel 15. Plug the camera in there and it will work.

Your NVR IP addresses are a bit mixed up too - it looks like you have been changing them.
What's the IP address of your LAN router?
Do you have a cable hooked up from an NVR POE port to the LAN router/switch?

I just noticed that the .3 camera now has it's own IP address as it's default gateway.
You really should not just randomly change these things - set them up as follows:

The camera IP address should match the IP address that is assigned to the POE channel you want to connect it to.
The camera default gateway should be set to the IP address of the NVR POE interface.
The camera DNS should be set to the IP address of your LAN router, or 8.8.8.8

I just plugged .3 to channel 15 and still no video. I should rename them as 192.168.254.1, .2, and so on...
IP Address of my LAN Router = 192.168.1.254
Yes. I do have a cable hooked up from NVR POE port to LAN router.

I just changed the camera .3 Gateway to 192.168.254.1. THANK YOU

Can you elaborate on these two and perhaps could provide me with an example for each?

The camera default gateway should be set to the IP address of the NVR POE interface.
The camera DNS should be set to the IP address of your LAN router, or 8.8.8.8

Yes. I do have a cable hooked up from NVR POE port to LAN router.

Unhook the cable between the router and the NVR POE channel.
Connect the PC to the NVR POE channel.
Run SADP.
Note down the IP address of the NVR. That's the 'NVR POE interface IP address'.
Normally it would be 192.168.254.1 but I suspect you have customised it.

The camera default gateway should be set to the IP address of the NVR POE interface.

That's the IP address that should be used as default gateway for cameras connected to the NVR POE ports.

The camera DNS should be set to the IP address of your LAN router, or 8.8.8.8

Your router IP address should normally be used for the DNS setting, but it's quite common to use Google's DNS of 8.8.8.8 instead.

Thank you. I will have to take a look at it again this weekend.
