Device lost on cameras, no debug logs

[roydonaldson11]

I have 5 Cisco 6630 IP cameras all setup and working, 3 work perfectly, the other 2 continually disconnect. The log files show 'Device lost' and no more information than that.

Try to run Wireshark to see tcpdump or udp. Maybe there are a network problems.

It's 4 and 0 I'm having issues with:

if I drop the video quality on the camera from 'Very High'to 'Low' it seems to hold the connection much better. The camera is set at 720 resolution.

run "netstat -e" - maybe you have a errors on Interface. If they, its a link problem in cable/router/switch on the way.

Wireshark will show you why connections lost (retransmission, maybe).

RTSP Not Implemented errors being sent from iSpy

.99 is iSpy

.104 is camera

Check the firmware versions on the cameras. Possibly the ones that don't work have older or newer firmwares that have an issue.

Firmware / model / configs are identical. It kinda looks like iSpy is not processing the data it is receiving fast enough. I see TCP zero windows being sent from iSpy and then the RTSP 501 Not Implemented is sent. I've attached a completely clean trace from turning the camera on, to the first fail. You can see it failing at Packet: 4030

CPU is at 7% RAM 50Mb.

Are the 3 that are working always the same 3? If you disconnect one does another one start working? If it does then it'll be an issue either with the network traffic load (wifi? lan?) or with the cpu load on your PC. If it doesn't then it'll be an issue with the network connection to the camera or with a firewall/ antivirus or with the camera itself.
