NVR Alarm Out/Trigger/GPIO
NVR Alarm Out/Trigger/GPIO
I require a means of triggering a very loud mains voltage siren for a small 4 camera security system, however it appears only the 32 channel NVR provides this functionality.
Are there any other straight forward ways of pulling this off? Perhaps a small stand alone POE GPIO interface could be released to augment the VIGI lineup?
