Connecting to distant location

[sussexman]

I am looking to put two hikvision cameras on and in a garage approx 40 metres from the house and would prefer not to run cat6 cable across the drive. What would you consider the best way to connect them to the nvr in the house?
Could I use a wireless bridge with a poe switch in the garage or is there a better way or has anyone used a powering connector with a switch at each end.

Any one done this and got it working succesfully?

You've answered your own question - use a wireless bridge in point to point transparent mode. At the house end hardwire it to your router (or directly to a port on the NVR), at the garage end connect it to a PoE switch and connect the two cameras to that. It works fine but to avoid issues, you would manually configure the cameras and the NVR channels to match before connection (don't rely on plug and play). As an example if the bridge was connected to a PoE port on the NVR:

• Power up and activate the two cameras. Address them 192.168.254.10x and 192.168.254.10y (where x and y are the channel numbers. You could use anything but it's easier to remember the addresses that way and they won't interfere with NVR assigned plug and play addresses)
• Manually edit the two channels on the NVR to match the two IP addresses above and enter the password you used in the camera.
• Connect it all up

If it's more convenient to connect the bridge to the router at the house end, it's the same as above but set the camera IP addresses to match your local network rather than 192.168.254.x

If your garage uses the same electrical distribution panel as your house try a powerline adapter first. I’ve used these around the house between NVR and cameras with no problems. 40m to the garage will reduce throughput.

Sometimes wireless bridges can add latency to networks if not planned right. Make sure the antennas can see each other with no large trees or bushes interfering with the antenna direct line of sight.

Results with Powerline can be equally problematic. Even when the devices are connected to circuits on the same distribution board, speed and reliability is best when they're on the same circuit and plugged in directly to the outlet (I've known them not work at all when connected via an extension lead). They're less reliable when on a different circuit, worse still if the two circuits are on a different RCD (on a split load distribution board), or if the two circuits use individual RCBO's for RCD protection.

I've had a couple of installations where the powerline adaptors worked well when initially installed (and speed tested to check speed and latency), only to have issues with the link being lost intermittently requiring the units to be power cycled or factory reset. Part of the issue is that electrical noise affecting the link isn't visible. At least with WiFi, link quality is visible and can be mitigated with channel selection.

I'd maybe attempt to do the link with powerline as it's the cheapest and quickest to deploy, but I'd be prepared to replace it if it didn't turn out to be reliable.

Agreed, both methods have their pros and cons. A lot of wireless bridges are poorly installed because the installation instructions were not read or misunderstood. For wireless links the usual problem I see is a compromised LoS first fresnel zone followed by RF adjacent or co-channel problems.
