Option C: ethernet over power lines

Original post 11/26/2018:
Been awhile since I tried one of these (and was very disappointed back then) but given the fun keeping cams down at the creek has been I thought I'd try it again. I bought one of the TP-Link AV1300 / AC1350 Gigabit Powerline Wi-Fi Adapter Kit | HomePlug AV2 Technology w/Beamforming | Plug, Pair, and Play (TL-WPA8630 KIT V2) because it had 3 ports plus WiFi AP built in. I should mention this is in a heavily wooded area outside my fenced in area. The cams are also close to the creek and I've had a couple cams near the creek stolen and wires cut. I was getting OK reliability  with a serious outdoor AP. A Unifi Outdoor+ with Ubiquiti Airmax Omni AMO-2G10 10Dbi 2.4 GHz Rocket Kit which could cover an acre without all the trees. I also tried putting an Unifi Outdoor+ down in the trees but since it was mounted in a tree the connection was flaky plus I was not happy with the idea vandals could get to a cable wired directly into my network and could fry some hardware. With the power line option they might destroy equipment outside the fence but not inside. So far it is working great which is kind of surprising on a couple levels. First from my previous disappointing experience. Then there is the whole AC noise issue that made me move from X10 to Z-wave a few years back. And I did not make it easy. The connections goes from the switch, to the inside adapter, to a 75 foot extension cord with neon power indicators in it (it was in place already), to and outside plug, through a Z-wave power switch, down a line about 55 feet to a breaker box, down another line to and outdoor outlet about 60 feet from the breaker and then lastly another 50 foot extension cord to a waterproof box where the receiver and POE injectors are. Despite that AP being in a box on the ground the WiFi seems to work pretty good too. This comes in real handy for adjusting the cams out there where getting between the tablet and the AP can be enough to lose a large percent of frames if not the connection.

Note I had bought a couple CelerCable CAT7 Slim Flat Ethernet Patch Cable with Snagless RJ45 Connectors, 50 Feet - Black with the though they might be harder to see laying flat against the trucks of the trees but be warned these cables got hot running 12 volt POE through them. Using the Huacam HCP05 Passive PoE Injector/Splitters of course. The resistance in the cable was so bad the Amcrest IP4M-1026B would drop offline when the IR LEDs kicked on. I ended up routing the power through the old power cables till I receive replacement cables.

Update 7/25/2019:

The install down by the creek has been working well so I started thinking of doing similar out by the gate. This involved running about 300 feet of armored 120 VAC cable through the trees from the house breaker box and putting the home end on a different circuit, though on the same phase on the main. This would seem to be well beyond the specs but it appears to be working fine at an average of 230 kB/s. Note the price might be a bit daunting though. By the time you add in the cable, breaker, connectors, GFI outlet, boxes and such it came out to almost a $1/foot. With the Ethernet of Power being the first $100 of that. But it is handling 30fps of 720p just fine across the built in WiFi which is much better than the 1-3 I was getting before and should let me upgrade to cams with better data rates without worrying about how well their WiFi is.

So far the only downside seems to be that I'm not getting traffic status in the network monitor anymore since a Unifi port or AP is not the first contact point for the clients. Though I can get the traffic stats on the Unifi port the home end to plugged into.

Next I want to swap out that old Foscam FI9804P 720P Outdoor HD Wireless IP Camera with a Wyze cam with sensor hub in an outdoor case. And probably another wide angle cam to watch the street. I'll have to see how it handles the load.

Added filterable sheet to camera compare

On my Camera spec compare sheet I added a transposed version of the HD cams sheet called HD filterable. It is not as readable as the other given it is over 200 columns by almost 30 rows but it had the advantage of being able to filter the camera models by all the features you are interested in. Just go to the HD filterable sheet and create a temporary filter

Then click on the down arrow of each column you want to filter.
For instance here I selected Brand, Color and Viewing Angle such as

What is the best camera for X?

I see that question posted a lot. Often just "What is the best camera?".

Answer

It really depends on what you are monitoring and the features you need to do that. Things to take into account:

  • Need audio recorded?
  • Do you need to be able to talk back?
  • Distance to main target area?
  • What level of recognition are you looking to get? Motion, face or plate at 3 feet or 200?
  • Wide, average or narrow view angle?
  • Is a wired ethernet possible there?
  • Is power available there?
  • Is night vision required and if so to what distance?
  • How weather / theft proof is needed?
  • Is zoom wanted? If so auto or manual?
  • Is pan / tilt wanted, if so should it track objects automatically?
  • Are you going to use a DVR? If so do you have one or are you looking?
  • If thinking cloud recording do you have the upload bandwidth for the number of cams you want? What length of storage are you expecting?
  • Do you want continuous recording (the answer to this one ought to be yes somewhere if only on the camera or DVR.) 


This why the 40 I currently have online are a mixture of brands and models. See my compare sheet.

To find the best camera you need to first gather the answers to most of the above then ask that question again.
