3RDIGLBL 0 Posted May 31, 2008 Looking for some advice here. We have a potential customer that called me today looking for a replacement system to his Digiview DVR that he is having endless problems with. This is an auto auction place so they have a large yard with 6 cameras currently. He wants a 16 channel DVR so I am looking at a Geovision system. Combo card 16 channel 480fps with PTZ control and alarm connectivity. They want to have a sensor setup across there entrance which will trigger an email to be sent to there cell phone or the alarm trigger. I believe the Geovision system can do this. Now the issue we have is locating a sensor that will work over an entrance span of 170'. I think to find something that will span 170' we will need somekind of laser beam with maybe a reflector on the other end?? I've never done anything of this width before so I am really uncertain of the required equipment. I will also need to get some additional cameras to cover this wide of a spread maybe 2 cameras focused on the entrance alone? Thanks Share this post Link to post Share on other sites
alanjh1965 0 Posted June 5, 2008 I can't comment on Geovision, I haven't used it. But take a look at Optex they have Dual Infra Red Beams which can cover up to 500ft ! Very reliable if set up correctly. Only problem they need 12volt power both ends which could be a problem on some properties althought they have a solar powered version. They have a clean relay alarm ouput so you have options were to send the alarm to. If Geovision has alarm inputs you could use that or you could buy a Speech/Text unit from Texacom which could send a SMS text message or pre recorded message to several cell phone numbers. Have you thought about how to turn the beams on and off ? You could put a keyswitch in a waterproof box outside the area of the beams. Just a few ideas for to think about !

3RDIGLBL 0 Posted June 6, 2008 Thanks for the reply and ideas. I'm going to check out Optex I appreciate that. As far as turning the beams of and on I figured I would just setup a schedule of when to use the alarm within the DVR. That's the idea anyhow. Using a switch is a great idea as well I guess I could put it in somekind of weatherproof lockbox. Share this post Link to post Share on other sites
