fragmental 0 Posted April 22, 2011 Hi guys, I`m trying to put together a system and I need some help if possible. I have 20 years experience as an electronics tech but the cctv thing is new to me so be gentle lol. I've drawn a rough sketch of layout of the cameras and buildings and I'll try and link it here. http://img638.imageshack.us/i/camsystem.jpg/ I need to add 3 cameras to an existing analog DVR system.These cams are outside and 2 of them will be mounted to the top of 30' telephone poles. Any suggestions on cameras? I'm guessing they will have to be high res to cover the area I need? Can i use the existing 600' of rg59 for one camera? Can I bury my other camera wires along with the AC wires to power the Cams and any suggestions on wire type would be great. I'm guessing twisted pairs with Baluns? Can I transmit the video back to the main building 1200' reliably? I see some 2watt 2.4ghz transceivers on ebay cheap... would they work? Sorry for asking so much, I only have a week or so to let them know if I can put together a system that will work so any help would be appreciated.

Soundy 1 Posted April 22, 2011 I need to add 3 cameras to an existing analog DVR system.These cams are outside and 2 of them will be mounted to the top of 30' telephone poles. Any suggestions on cameras? I'm guessing they will have to be high res to cover the area I need? Depends on the level of detail you need. Can i use the existing 600' of rg59 for one camera? Yes... although 600' is a bit of a long run for analog video over RG59; you may need a booster. Can I bury my other camera wires along with the AC wires to power the Cams Ummm, you CAN... although if you're talking about 120V/240VAC, I would STRONGLY recommend against it. Not only is there a good chance of interference, but it's not very safe, and contrary to just about every electrical code in existence. If you're just talking 24/28VAC, then yes, that's fine. and any suggestions on wire type would be great. I'm guessing twisted pairs with Baluns? That's one option... would make cabling easier in some cases, as you could run up to four video signals over a single Cat5e. Can I transmit the video back to the main building 1200' reliably? I see some 2watt 2.4ghz transceivers on ebay cheap... would they work? Definitely not - you'd be lucky to get a reliable, clean signal at 20', nevermind 1200'. Sorry for asking so much, I only have a week or so to let them know if I can put together a system that will work so any help would be appreciated. Whether you CAN isn't so big a question as how much it will cost - almost anything is possible with the right budget. Share this post Link to post Share on other sites
fragmental 0 Posted April 26, 2011 Thanks for the response. It might be best if I was to contact someone who sells some of this equipment and let them help me put together a package for this. Any suggestion of a good supplier in Canada for cctv stuff. Are there better quality rf video transmitters that would do a decent job over 1200 feet or is it just not happening.

Soundy 1 Posted April 26, 2011 Where in Canada are you? There are RF systems for analog video that will do the job for you, but I don't think you even want to know what they cost. You'd be better off using an IP encoder at the remote end, and using some long-range WiFi products like Ubiquiti (much cheaper). Share this post Link to post Share on other sites
fragmental 0 Posted April 26, 2011 I`m from Nova Scotia. I did check and they have internet at both these buildings. Could IP cams work here I didnt know if I would be able to convert this back into analog video for the existing DVR.... is this an option? My main concern is a reliable system with good performance. If its going to take 2-4k in hardware to make it work right that's fine as long as I know how to bid on it:) Share this post Link to post Share on other sites
Soundy 1 Posted April 26, 2011 If you're going to send video via the internet connection, you'd be better off using a hybrid DVR that can simply record the IP stream, rather than trying to convert it back to analog. Be aware that streaming video this way can be data-intensive and may not work smoothly if the remote location doesn't have sufficient upstream bandwidth, or may cause over-usage charges if the ISP has them. Hmm, Nova Scotia, you're about as far away from me as one can get in Canada (I'm in the Vancouver area)... pity, I'd come take a look at your set if you were on the other coast Share this post Link to post Share on other sites
