lilinyn 0 Posted May 6, 2008 Hi guys, How can i change cpcam cpd560 dvr alarm duration to 1 sec only. The minimum now is 5 sec . Need any firmware update ? Share this post Link to post Share on other sites
scorpion 0 Posted May 6, 2008 There are no changes that I am aware of. You can put a piece of tape over the piezo device, just do not cover it up 100%. Let it "breath". Then again if your are using alarm then that is what it is supposed to do. It is supposed to wake up the night securtiy guard so that he can take action! Opps! Did I type that? I take that back! Most security guards are professional, and they are alway on their toes. There are the 1% who ruin it for everyone else! Share this post Link to post Share on other sites
lilinyn 0 Posted May 6, 2008 yes, thought of that also. actually i make motion alarm for my front door at my shop as i'm always at the back. but 5sec sometimes not very comfortable. if can make 1 sec it will be great. just "beep" 1 times and i will alert there are customer at the front.

scorpion 0 Posted May 6, 2008 I wonder if you can cut the piezo and put in a "flip flop" circuit, and a way to reset it. This way you only get one beep. Share this post Link to post Share on other sites
Kiwi 0 Posted May 7, 2008 The alarm output connection triggering a beeper via a common 555 timer circuit would work just fine. You should be able to buy a suitable kit at Radio Shack. Share this post Link to post Share on other sites
