becooler2013 0 Posted March 6, 2013 I'm a computer and electronic technician...Lately, I have been installing analog video camera systems with no problem at all...The last installation I did took place in the building I live in. Fortunately for me, my landlord brought the whole video system...I installed 8 cameras inside and outside the building...Now he asked me if I could install ip video cameras...I do have some knowledge about computer ip address for instance but just a little bit of ip video systems...Some of the questions I have would be the following... 1.- Do I need to configure the ip cameras with ip addresses... 2.- Since this new installation requires at least 500 feet of coax cable, do I need a device to bring the video signal from one end to the other end ?... 3.- How I'm going to power the cameras ? I would like to find a good system for putting all these ip video cameras over coax....Any suggestions ?? Thank you for any help.... Share this post Link to post Share on other sites
SectorSecurity 0 Posted March 7, 2013 Yes your IP cameras will require an IP address to function properly. Next why do you want to run over coax? Why not just run new CAT5e with a POE switch or a POE injector? This will allow you to transmit the video and the power down one cable. Share this post Link to post Share on other sites
GrouchoBoucho 0 Posted March 7, 2013 1.- Do I need to configure the ip cameras with ip addresses... yes; cameras are just like any other network device. 2.- Since this new installation requires at least 500 feet of coax cable, do I need a device to bring the video signal from one end to the other end ?... Next why do you want to run over coax? Why not just run new CAT5e with a POE switch or a POE injector? This will allow you to transmit the video and the power down one cable. you can only run ethernet for 100m/330' over utp. yes, you can use coax, via ethernet-over-coax adapters. there are several different brands out there; i've recently been using altronix ebridge adapters quite successfully. they make a version that will send poe over the coax along with the ethernet. 3.- How I'm going to power the cameras ? if you're replacing existing cameras and re-using their coax, you can use the existing power (usually - check voltage requirements). if you're putting in new runs, you can pull a power cable along with the signal line... or use power-over-ethernet (poe). I would like to find a good system for putting all these ip video cameras over coax....Any suggestions ?? Thank you for any help.... again, eoc adapters... but unless there's some *specific* reason to do this (like the distance factor), stick with cat5e. it's cheaper (*much* cheaper if you factor in the cost of the eoc adapters), and far easier to work with. remember that the cable technically isn't carrying video... it's just data on the network. imagine it like youtube, streaming video to your browser - an ip camera is a similar idea, digitizing the video and sending out a video stream, that the nvr or vms software receives and records.
