It could be Apache, but I only just built the zm on Ubuntu 7.10, and obviously got the latest Apache. Apache is so widely used I would be surprised if it was allowed to have a memory leak for long. I used a little program to monitor the memory leak, it displays it on screen and writes it to a log fi...

Thanks for the information about authentication breaking the picture. I just built a system the same as you with Ubuntu 7.10. It seemed to be working (albeit with a memory leak) then I could not show the images. (Picture of a broken link). I was about to try and buy a CCTV appliance. You have restor...

Thanks, for the suggestions. I've tried moving the PCI video capture card. I've disabled the Parallel and serial ports. I've tried zmc -d /dev/video0 I've tried PV149 card, PV143 card, a sky card. Two different PCs. The results are the same: ZM looks like it is working except no picture The video in...

Don't worry about extending Ethernet over its section length, If you use the Allied Telesyn AT-MC601 / AT-MC602 it is just VDSL, about half the homes in the UK run DSL over a mile. It wont impair IP performance.

P.S. You dont need to worry about difference in ground potential if you use Video Baluns as they act as a matching transformer.

Whist fibre can go a lot further than copper, Terminating copper cable is less fiddy and less expensive.

Video Baluns should be more reliable than Media converters as they are passive - just a matching transformer with appropriate BNC / RJ45 and Power connectors. The URL: http://www.eql.com.au/cctvbalun.htm gives a graph of volt drop over distance of Cat 5 for several different camera power consumption...

A Video Balun is just a matching transformer with appropriate BNC / RJ45 and Power connectors, if it provides power, it is not strictly just a video Balun. The URL: http://www.eql.com.au/cctvbalun.htm gives a graph of volt drop over distance of Cat 5 for several different camera power consumptions. ...

Hi, I tried the dmesg command, it does look like the PV149 card has detected the card OK and set each chip to 98. If mod probe is not the area I should be looking at, any Ideas where I should be looking? I am worried that it might be videoforlinux configuration, but I looked for documentation on thi...

PoE cameras either have cheap optics or cost a fortune. You might want to look at Video Baluns, quality analogue cameras and analogue video input card in the PC. You can then power the camera and get the video back using Cat 5 rather than Co-ax. The Cat 5 has better performance than Co-ax so goes fu...

Thanks Lee and aot2002 for your interest and replies. When I try to display the picture in zoneminder under ubuntu, I get a white square, in it an icon indicating a broken link to the picture. I tried sudo modprobe bttv card=98,98,98,98 which did not error, but did not seem to help much. I tried the...

Hello I have Ubuntu 7.10 and Zoneminder, installed using a partial set of instructions at: http://docs.google.com/View?docid=dcdq2w5w_0v3s94h The web pages are working OK and I have added a monitor configured as local /dev/video0 but it won't display any images from my shiny new PV149 that I got fro...
