Hey guys. I'm moving a set of old cameras to a new NVR. It's a mix of many different models and I've so far successfully just connected the cameras to the new switch, found them in SADP and then reconfigured them. I have now, however, ended up with four cameras that I can't reach via SADP. From...

Hey guys. I am about to install a setup with 3 Hik 2142 connected to a switch which in turn is connected via Ubiquiti air bridge to the NVR. I know cabling it would be better but let's leave that for now. I bought a Ubiquiti Toughswitch which is powering the AirMax over PoE and I want to power...

Hey guys. I've crossposted this one from Alarm & Security systems since I believe it fits both places and I haven't got any replies on there yet. I want to build a security system that is possible to move around. Like a temporary CCTV/security system you see on building sites and the like...

Hey guys. I want to build a security system that is possible to move around. Like a temporary CCTV/security system you see on building sites and the like. Needs: - 3-6 cameras - motion sensors (separate of the cameras) - Lights triggered by the motion sensors - A speaker giving a warning...

Hey guys. I've coded an Arduino pro mini 3.3v to look for a broken laser beam. Whenever the beam is broken for more than 5 sec the arduino will set one of it's digital outputs high. My question is if I can use this digital "high" out to trigger the DI on my camera and if I can just wire it...

Hey again! My previous post didn't get much attention so I'm trying to rephrase my thoughts here. I hope some of you can give your thoughts on this setup I want to make my NVR trigger a set of 3 simple LEDs and two more powerful 48W lamps (like these) but I'm unsure how to wire things. I'm...

Hey guys. I've been searching a lot for posts of how to wire anything (sirens, lights, whatever) to the alarm out DO of my NVRs. As far as I can see these outputs differ in type on different NVRs. Some are "open collector" some are relays. My specific NVR's (Vivotek ND8322P and ND9441P) are of...

Hello guys. I have a setup with 10 Hikvision cams (DS-2CD2432F-I and DS-2CD2732F-I) (running 5.4.5) I'm trying to add a Vivotek NVR (ND9441P)instead of the badly functioning Hikvision NVR. The problem is that this Vivotek NVR cannot add those cams. I know mixing brands is not alway a good idea...
