Alarm Output Through Camera To Light Up Strobe/Siren Using IVS Tripwire

[McNotty]

Gidday from NZ,

This forum has been amazing, and I've learnt so much scrolling through the seas of information. So thank you all.

I've got a single camera setup for front of house and want to utilise the alarm output on my camera as the NVR doesn't have alarm outputs, only being a reasonably basic model.

The camera is an Empiretch 4K Colour turret and the basic 8 channel NVR with no alarm outputs.

I've got a couple relays that I'll run from the camera alarm output, one standard relay for a strobe and a timed delay relay for siren should the strobe not be enough of a deterrent. Both relays will have 12V power to them from supply on other end to power the external devices.

My question is how in the camera GUI settings via browser do I get the alarm output to power up on activation of the tripwire I've set? Any help would be much appreciated.

If I was to connect the brown alarm output and green ground wire to the low amperage side of relay, should I be able to get it to switch by activating an alarm as a way of testing it?

Cheers

Scott

I should also note, I've ensured that all the camera settings are adjusted via the camera GUI and not the NVR. I only use the NVR for viewing footage.

No normally the Alarm output is mis marked as a Wet contact with 300ma and to be honest from all the devices that I have setup with Alarm outputs this is not a wet contact but is a Dry contact.. So what this means is that if you were to connect your Relay setup with Power and Ground going to relay so the relay is active and then cut the ground wire. Now connect your cameras dry contact between the 2 wires you just made. 1 going to the relay and the ground form your 12v then when your camera relay out engages it will make your ground complete and make your relay active.. Relay in camera off it cuts that 12v ground form your power supply open and doing so will close your relay and turn off what ever you have connected to them..

This is a very rough draft lol.. But the image below shows how it would connect with camera relay contact.. What I didn't put in the image is the output device siren or light.. The NO contact 12v would go to your device and the ground from the power supply goes to the device.

1 standard relay has marks like 85, 86, 87, 87A and 30.. If you have different relay same concept. Some relays will only have 4 pins other can have 5 and if not a common relay it can have as many as the relay will let one have but mine was showing a SPDT setup..
