crazythunder 0 Posted February 21, 2008 i'm purchasing a dvr as soon as my tax refund gets here. i have a couple of questions regarding the alarm input\output on dvr's. can someone give a quick reference guide on how these work? what can i plug into the inputs\outputs? i'm somewhat aware that you can install motion sensors,sirens etc. but i'd just like a little more info. such as what are voltage requirements etc. can i simply plug in something like this strobe into one of the inputs?{SLC Strobe 60,000 candle power output, 180ma current draw, Two wire connection, Operates on 12VDC) or would that be output? and how would this strobe be activated? through the dvr motion detect or from another external motion sensor? this is where i need info. thanks in advance for anyones reply.

bike_rider 0 Posted February 23, 2008 Lot's of "it depends" answers in there. Alarm Inputs send info to the DVR. For example, that is where motion detector would connect. What the DVR can do based on that input depends on the brand of DVR. Outputs of course go the other way, they trigger an external action. Generally these are ultra low power setups. For example one set of Geovision outputs is limited to 2A at 30V DC or .5A at 120V AC. Outputs are not power sources, they are only switches. They idea is that they would close an external relay, which in turn would power a device. Share this post Link to post Share on other sites
