Hello everybody! In the summer I decided to upgrade my surveillance system and my home network. Until then, I had 4 wireless Foscam cameras with a Foscam NVR and the quality was terrible especially at night. I am an IT professional, but I haven’t dealt with CCTV systems in the past, so that was my first installation.

That was my rack cabinet before the upgrade:

After some research I decided to go with Dahua IP Cameras with an NVR. I wanted to build something that will last so I chose 8MP Cameras supporting 4K resolutions, especially:
  • 3x IPC-HFW4831E-SE (Bullet) – 2.8mm Focal length
  • 2x IPC-HDW4831EM-ASE (Dome) – 2.8mm Focal length
  • 1x IPC-HFW5831E-ZE (Bullet) -Varifocal (2.8mm-12mm)
  • 1x NVR5208-4KS2 (With 2x2TB WD Purple Disks)

I have Cat6 cables running through the house, but I had to install new cables from inside to the garden and that was the hardest part as the house is surrounded by tiles. So, I chose the shortest corridor and I cut the tiles in order to install a tube under the ground:

After that, the remaining installation was easy. I buried the cables underground and led them to the Camera positions. I installed a small 10” rack in the boiler room where all the camera cables terminate and installed a D-Link POE managed switch. Also, I left 4 cables inside the garden junction box for future use and I installed the Cameras:

Now it was the time for the Rack cabinet. I decided to put the NVR inside the cabinet and distribute the signal through a DVB-T Modulator. Since I was out of slots in the rack, I installed a 6U short rack and placed another patch panel in the side to hide all the cables for the cabinet devices.

The chaos during the cable patching:

Did the required testing:

And the final result with a small 8” monitor that I installed for some basic NVR configuration:

And that was my setup. It took me almost 1,5 months working only on the weekends.

Now I have a question, I want to create an automation so when someone hits the doorbell the camera with the varifocal lens zooms in and the NVR switches to 1 full screen view of this camera. I found the Dahua HTTP API and I was able to Zoom In and Out programmatically through a node.js server running on a raspberry pi but I couldn’t instruct the NVR to switch to 1 full screen view. Is there any way to do this? Or perhaps using the RS485 interface of the NVR?

You could do this using one of the alarm inputs on the NVR.

By selecting Tour and set only the current channel? I will try that! But I think the only downside is that the screen flashes every time it goes to the "next" channel (same channel).

Also I ordered an RS232/RS485 to Ethernet adapter to play around with PELCO commands.
