![]() I had been dropping signals on just one camera of 16 total no POE 24 VAC Power. I had a similar issue with GeoVision VMS and a new camera. I don't or won't know if this helps or not but you can see you're not alone. ![]() We found that the POE switch had unstable power, and replacing the switch solved the problem. If you have Axis cameras, do you see anything unusual in the System Report? Depending upon what the cause of the problem is, you may get some insight if you set up a syslog server and enable syslog on the cameras.Īt the same site we also had an outdoor Axis P1347 that would go offline every few weeks. It's now been a year since we had the issues, and no problems. we fixed some bugs related to the camera going offline. We upgraded to the latest version of firmware at the time, because per the release notes there were "improvements to camera robustness" - which we interpreted to mean. (3) We went months without an issue, then a camera went offline. The server names were no longer reachable, and this was the source of the link errors. It turned out that these cameras had not been reset back to factory defaults for the VMS change, and the previous VMS software had created settings inside the camera that were visible in the System Report, but were seen in the camera's setup pages unless you knew where to look for them or caught them in the System Report. (2) The system was originally running one VMS, and when the company was bought out their service dropped to zero, and we switched to Axis Camera Station software (it's a 50-camera system, no moitoring, just infrequent review of recorded video). The client software would connect, but getting recorded video from the server was slow as molasses in January. It may have been that the cable problems caused the connections to degrade to 10 Mbits from 1Gbits, as we experience that with some other workstation connections that had bad cable. That was replaced and the packet issue cleared up. (1) Some of the cable was bad when we re-tested it with a cable tester. It turned out to be a combination of three problems. Plus for some of the cameras packets were getting dropped but not consistently. Network monitoring showed a really high rate of link errors for the four cameras, like 1,000 per day when we should have seen zero or one per week. Usually they would not respond to ping when offline, but sometimes they would even though the web interface was down. Cycling the port would restart the camera and get it back online. Over a 2 to 3 week period, one would go offline, sometimes two. Four of eight M1054 cameras would go offline, same symptoms as you describe. I ran into this issue last year with a set of Axis M1054 cameras. The most recent episode happened yesterday (after a week of having no issues) and in the past 24 hours it has happened twice. The camera cable lengths vary between 50 to 250 feet but cameras on short cable runs will go down as well. I also connected one of the cameras to an Axis midspan POE injector but even that camera at one point went down as well. I have spoken with Digital Watchdog technical support people on several occasions and most recently they suggested to me that it may be a power issue so I replaced the switches. The only way that I can put the camera back on line is to power cycle it by shutting down the POE switch or unplugging the camera's ethernet cable. The camera that falls off line can be pinged but the you can not access the camera's web browser. It is not always the same camera and it is not always a camera on the same switch. ![]() ![]() Periodically (every three to seven days) one of the cameras falls off line. All of the cameras have been assigned static IP addresses that I was given by the IT people that manage their network. The system is installed in a small commercial environment and is connected to their network for internet access and local viewing. ![]() I'm using outdoor CAT5E cable to all of the cameras with the exception of two which have standard CAT5E. I am using two Trendnet eight port gigabit POE switches. The system consists of a Digital Watchdog NVR (Blackjack Blade - Spectrum) with eight Digital Watchdog DWC-MV421D 2.1 MP outdoor cameras. I am having an ongoing technical issue with an installation that I did a few months back. ![]()
