Analog upgrade to IP cameras with cable length/camera distance issues

[vhp]

We have an existing 8 camera system with a DVR installed to cover multiple properties on acreage.
Cameras are located many hundreds of feet apart from the DVR, and use passive baluns on each end to send each video signal over a single pair in underground CAT5 cables that carry multiple camera feeds.

For the furthest distance cameras, there are extra, unused coax cables I can use. For some others, there are empty conduits I can use, and for some, I may have to pull new coax to replace the CAT5.
I want to upgrade to 10 or 11 IP cameras, and probably use multiple Highwire pairs to push the camera feeds over the longer distances.
Power is available for locally sourced PoE near the furthest distance cameras. All camera feeds run to the shop building, and then on to the main house where the NVR will reside.
The shop has a LAN connection to the main house and spare CAT5 and coax cables to the main house as well.
Here's one possible layout. Will it work? Are there better options?

You possibly could employ Ubiquiti Wireless transmitters( other brands available as well) for the really long runs @ 500-600& 800 feet.
I ran 2 IP cameras and a pair of Ubiquiti Loco Nano wireless bridges with a POE switch to a remote building to monitor a parking lot. which worked fantastically.

This distance and the terrain ( A pond, an underground Natural gas line, and Underground 220VAC run, and asphalt) made wireless a good option. Working to this day. Installed about 4.5 years ago.

this guy @ TRLcam has some really big distances covered with versions of wireless transmitters.

If you don't mind answering one more question, how are you powering the Unifi equipment and the camera? The Dahua is standard 802.3af (48v) while the UBNT stuff is passive 24v.

Good question. On this installation I power the IP camera using the 12vdc input connector and the Ubiquiti airGRID M and NanoStation M wifi equipment with 12vdc. With the Ubiquiti, if you took a 300' run of cat 5 and put a couple Ubiquiti access points on the end and measured the voltage at the far end, it would be quite a bit below 24volts. So, in this application where the total length of cat 5 is...

I presume the above wireless recommendations are for some sort of dedicated directional point to point signal transmission.
I'm not a fan of wireless, and at least one family is very much against adding any more EMF to our crowded spectrum, even going so far as to revert to manually read electric and gas meters and not using WiFi in the house.
We have hundreds of trees all over the site, too.
WiFi itself has inadequate bandwidth. We had that at one installation with just four (1080?) IP cameras, and had to reduce the resolution to get it to work at all.
And we already have miles of conduit going in every direction we need, that we can leverage.
My questions have more to do with whether the HighWire arrangement will work, especially when combined with camera feeds from multiple directions, going through an intermediate building, etc.
We already use HighWire at another site to run two IP cameras at the gate about 800 feet to an NVR in the house, and that seems to work well.

You could use ip to coax converters for pushing ip over existing coax. I think a lot of those can push a reasonable amount of power over the coax also, as long as it is copper coax.

You can also push 90w from a POE injector over CAT5/6 and send it to a POE powered (called a "passthrough") switch that can supply 66watts for 4 ports. I have had good success with this model with 4 POE outputs, though I used it with only two cameras and fed it 60w, which outputs 40 or do watts. It foesn't matter since most ip cams max out around 10w with illuminator on.

TP-Link TL-SG1005P-PD is what I have used.​

If you have conduit, you could pull fiber. It is pretty inexpensive to use premade OM3 fiber with SFP port switches and SFP converters. I've used Cable Matters brand converters with good success. Note that many of the smaller 4&8 port switches with SFP ports only support 1 Gigabit, so you cannot use SFP+ modules and must use SFP modules, even if you have a 2.5G or 10G capable fiber. Fiber is my favorite method for longer distances if I have power on both ends. You can even get dielectric versions so there is no continuity between buildings.

I always recommend fiber, but if copper has been working without going bad on its own (getting interference from water inside) or getting hit by lightning or power surges, I don't push people to change it out. Now if you are on a mountain 2/3 of the way to the top and keep getting lightning issues, then it becomes interesting and fiber can really help, especially if you can get most of the hit to ground at the gate or outbuilding and not come up low voltage stuff to the house.

I would replace the 600' & 800' coax runs with fiber, if you can. If you can't, use coax/ip converters.

With the cost of the highwires, you could probably do the "new camera north" with fiber for a very similar price.

If I were doing it and did not have any highwires purchased, I'd also replace the 600' and 800' with fiber. You can get premade fiber on amazon. I've bought several different brands and all have worked fine for me. No issues.
