erictopia512 0 Posted January 7, 2005 how does the whole alarm thing work? a lot of dvr cards say that it notifies you through email when the alarm goes off. do you actually have the set up an alarm system? or is it just used as a term? Share this post Link to post Share on other sites
rory 0 Posted January 7, 2005 Alarm means a zone from an alarm system, or a zone device such as a motion or beam, if just by itself. Some can also send a message on Event or Activity, which basically means motion detection, so no external devices are required. They can differ in their wording of this though.
