NVR Alarm Out Connection

Recommended Posts

I have a Hikvision NVR system that I am trying to utilize the alarm out contacts into a controllers contacts. The NVR has one pair of outputs which I have confirmed are ground and normally open (NO). I have tried connecting to the controller on the contacts 12+ & SIG but it is unable to trip the sensor. Any thoughts on how I can acomplish this? 

My goal here is to be able to when line crossed or motion on security cameras is triggered I want an output from NVR into C4 so that I can have an announcement (already configured) and have any TV that is on display NVR (also configured but need the trigger). Currently I am using an IFTTT trigger to accomplish everything but it has about an 8-10+ sec delay which I would like to reduce if possible. 

Any help would be greatly appreciated

Depending on the dvr model and driver there might be alarm out in the programming section.

 

If not try a 12v external power supply, wiring the + to the 12v in on the controller, - to the ground of the dvr, then dvr out to controller signal input. Also you need to have a contact driver in the project bound to the controllers contact input

Thanks Sonic, I have the contact setup and I wasn't sure if a 12v source would be needed. Ill have to give that a go.

That connection is a sensor INPUT - allowing the NVR to use an external sensor to trigger alarm recording (ie if security system is in alarm, trigger recording or higher quality recording) - not to allow the NVR to TRIGGER an alarm

The NVR I have has 4 inputs and 1 output. I can set triggers on the NVR  to activate alarm out under certain conditions. I can confirm when the alarm out is triggered it goes from normally open to closed.

If that doesn't work you'll have to use an external relay (as in not a C4 relay!) - tie the NVR output to the relay to close it, then tie a C4 sensor to the relay using +12 and sig
