ljarrald 0 Posted June 9, 2012 i have a few cameras in places with a high risk of attack. one of them has actually been attacked with a brick in the past. i bought some shock detectors off ebay. they are usually used on door and window frames in burglar alarm systems. i have mounted one inside each camera that risks being attacked. because i have run cat5 to each camera, i just used a spare pair for the alarm contacts. and then conneced them to the relevant alarm input on the DVR... as i say in the video, nobody has attacked the cameras since i've made these modifications. but my dad dropped a brick on one of the cameras the other day and sure enough, the sounder screamed its head off! i took the dome off and flicked the sensor in the video because i don't want to hit the camera in case i damaged it. sChpgl2GXfg if the video doesn't load, use this link.

EarlT 0 Posted June 10, 2012 Great idea. I am putting some cameras up well in reach of people and this seems like a good tamper monitor. Share this post Link to post Share on other sites

vector18 1 Posted July 6, 2012 Nice idea, but you might you want to invest in a tripod or cut down on the coffee..... Have you thought about having an email sent to your cell phone upon an alarm through the DVR? Share this post Link to post Share on other sites
ljarrald 0 Posted July 6, 2012 Have you thought about having an email sent to your cell phone upon an alarm through the DVR? yes i'm working on a system that will send my phone a text if the cctv does anything like an alarm, or if the fire alarm activates and stuff.
