    Troubleshooting Short term DC on PoE cameras.

    Another anomaly I discovered: When I am locally connected directly to the camera via ip, and I have a remote client connected over mobile internet - Remote client always sees movement/picture update first. Local image can freeze for minutes while remote client has no issues. (Unless connection drops) The internet connection is mobile/no cable. I use Axis cameras and Milestone VMS
  2. Hello, Hell of a first post incoming. I have total 7 PoE cameras installed in a manufacturing facility. Since i had no experience, i did the best i could while designing the system. I have one camera per PoE switch -> data switch -> PC/Server (Scheme added) I got the system up and working only this way when there were no cameras connected to "Data switch" hence the reason calling it data. So i have an issue where 4 of the cameras are unstable (right side data switch( cabling marked with "?")) Long loading times, connection drops, latency etc. No cable (Cat5e) should be longer than 100m/330ft. Power is supplied from single wall socket to whole system. Switches are 40W maximum output supporting IEEE802.3at, af. 10/100Mbps (up to 150meters) Most powerful/biggest camera max 20W usage. Usually when one camera drops connection, all 4 go down from that side. 5 seconds to couple of minutes. Usually couple of seconds. If it was power requirement, all 7 cameras would drop, same with bandwith limit i guess. The connection drops usually occur when i try to access camera via ip or simply trying to PTZ. I've been thinking about: New/secondary cable from data to data swith as it's been patched couple of times. (Rats bigger than cats, video on request) An PCI-e networking card specifically for cameras? UPS Gigabit data switch Eliminating link between two data switches and bringing two cables to server from each data switch. Any suggestions, troubleshooting/testing ideas welcome. Best Regards, H. PS! There is a router between pc and data switch. Also i have few empty leads for future cameras. Edit// 2 of the cameras on connection drop side are 1080p (one PTZ) and 2 704x576px (both PTZ)
