SureVeillance 0 Posted July 6, 2007 Looking to improve alarming and coverage for a residential system by adding 1 or more PIR. What should I consider when deciding whether to wire the PIR to the PTZ (Pelco Spectra - coaxitron) or to the DVR? Camera has 7 alarm inputs and DVR has 16, none of which are currently in use. Appreciate any insight or experience. Thanks! Andy Share this post Link to post Share on other sites
kensplace 0 Posted July 6, 2007 If the camera is not near the dvr, then its less wiring to wire the PIR to the camera, and let the camera zoom to a preset alarm position when the pir triggers. Otherwise, its a extra cable for the pir near the camera all the way back to the dvr. Share this post Link to post Share on other sites
CollinR 0 Posted July 6, 2007 Wiring it to the DVR allows you to move multiple cameras. I also suggest you use a dual technology motion rather then PIR. Share this post Link to post Share on other sites
