"Unrecongnised request" error

jlbrown

One camera often gives this error:

Error communicating with network device "Packing Benches". 5.3.4b2,80210,404 Error from network device. Unrecognised request (resource not found on server).

I have replaced the camera and still get the error.

The company that put in the new (and original) camera said they tested the cable and it was fine. Updating its firmware didn't fix things either.

Any way to find out what resource it can't find? Eg to turn on more debug info? Any other suggestions?

Camera Profile is 'Hikvision Camera', format is RTSP (video and audio)

This means that the camera is returning a 404 "not found" error when SecuritySpy is requesting the video stream. Under the Hikvision profile, the request that SecuritySpy sends is identical each time. Are you saying that sometimes it works, but other times you get this error? If so, then this points to a camera problem - the camera is actually responding, so you know the network is fine, but it's responding with an error message.

What make/model is this camera?

Thanks Ben. It's a DS-2CD2T65G1-I5

It also gives:
Error communicating with network device "Packing Benches". 5.3.4b2,70900,800 Error from network device. The operation timed out.

sometimes.

Think we'll replace the ethernet cable.

Ben

This is quite surprising, normally Hikvision cameras are very reliable.

Changing the Ethernet cable is worth a try. Can you confirm you are using a high-quality gigabit Ethernet hub, with the Mac also connected to this hub via wired Ethernet?

Ben, finally managed to get to the bottom of this. We changed the camera with another one that was working (ie in a different location). It still had the problems - so must be the camera, nothing to do with the cable or network connection.

So replaced the camera with new one from Hikvision. Same problem!!

Could not figure it out.

Then the installer just, as a long shot, to change the camera IP.

After that, not a single problem!

Must have been a conflict, but I have no idea what else is using that IP, or how to find out.

Anyway, all good now - finally!

Hope this helps someone else.

Hi James,

Good to hear you found the problem! Yes, an IP conflict could cause this - either it's another device set to the same static IP, or it's an IP that the router has distributed to a device via DHCP. Any manual IP address you assign to a device should be outside the range that the router uses for DHCP, to avoid this sort of problem.
