On my equipment trailer and tractor, I have a GPS. I would make these recommendations:
1. Get a tracker that has a reserve battery. One that will preferably last 3 or so days. This is because you want it to track AFTER theives cut the trailer battery source.
2. Get a 12 v system tracker that operates off the tractor or trailer battery.. Then I will tell you if there had been a power change or if the tractor has been started.
3. If it is on a tractor, trickle charge the tractor battery with a maintainer such a tender or Genisus. If a trailer, connect a solar controller and solar panel to maintain trailer battery and gps. If trailer, change brake system battery to good AGM battery - like a motorcycle battery.
4. There is not a good way to Hide a tracker and assume a thief can't find it. Mine is mounted on top of the toolbox with a formed kydex dome covering it secured with security bolts and nylon insert nuts. It is painted the same color as the tool box. Kydex can be heat formed at home and is really tough. This is thick Kydex, 0.1".
5. DO NOT get a tracker which operates on 2G or 3G. Get one that uses 4GLTE. And when they are available, maybe 5G.
6. Make sure the tracker had coverage where you want to use it. Probably the Big three - ATT, Verizon, or Tmobile.
7. If it is a tractor, I would install a ground cut off switch on the battery.
While you cannot prevent theft, you can make it time consuming and too risky to stay working one it. It is kinda like the two guys being chased by a bear. One guy says -you can't outrun that bear. The other guy replies - I don't have to outrun the bear, just have to outrun you. Make your equipment hard to deal with. And then, buy insurance which covers theft.
I use LoneStar tracking. Their software is easy and good, annual cost $49 annual for service. I think that is much higher now. Like everything else.
My trackers have geozone coverage, any movement alert, power change alert. I think mine are Titan wired. Best wishes
