Thanks for all your replies! I managed to find the IP-addresses of the four cameras through the old NVR and log in to them. It seems they were not Hikvision! Their webpage didn't disclose much information about the brand or model number, but by googling the firmware version I discovered that...

It COULD be that they're not Hikvision but I don't think so. They're from a company that sells Hikvision OEM product (custom stickers and a skin on top of Hikvision firmware). But since I haven't yet had physical access to them I don't know for sure. The cameras were all connected to a...

You are mostly correct. I cannot, however, ping the four troublesome cameras because i don't know their IP. I tried running an Nmap scan on the subnet I expected to find them on (192.168.0.x) but with no luck. It's a Vivotek ND9424P But the problem has not been concerning the NVR as such. I...

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...

Thanks. That's what i feared. I'm going to buy another PoE-switch then. Is there a PoE-switch that can supply both 24V for the AirBridge and 12V for the cameras or should I just have two separate power sources?

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...

Ahh. Cliff notes. Thanks. And thanks for the elaboration. It makes sense.

I'm happy with my Vivotek NVRs. Maybe Fenderman can elaborate about why you don't want the domes? I can't seem to find anything about it in the wiki

I will look into the Barix products together with DSC motion detectors. How will I go about having the sensors/Barix NOT wired to the Milestone PC? I want to be able to place the sensors on the other side of a building site without breaking the cable every other week. Also, what version of...

Thanks Fenderman. But. . If pir sensors can be integrated with BI why would I need a separate alarm system? And which one?

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...

Not much yet. So far I've ordered at set of these photoelectric infrared sensors. I'm not absolutely sure if their range is good enough nor how to wire them and code the Arduino. I've heard that the Vivotek cameras will trigger their DI if you connect 3.3V to them in reverse polarity. No idea...

Awesome. That's great info. Then I will try and wire it and see if it can pull the DI high.

The output on the Arduino is 3.3v, I've measured it. I was thinking about wiring the Arduino GND and say PIN 8 to the camera DI- and DI+. Will this count as common ground? Or should I pull another wire from Arduino GND to the camera and in that case where to? I've attached a screenshot of the...
