$150 including 1 year of service.
That's not bad, for the price, especially with cell service included. For most trackers, you'd have to buy the SIM, plus the plan/package to use it.
Something I forgot to mention earlier was that some companies (Zoombak and Rocky Mountain Tracking are the only two I can think of offhand) operate a subscription service. They provide the trackers, and generally charge a certain amount per month, with the fees based on a maximum number of "locates" per month. I think the customer still gets a visual depiction of where the tracker is, but instead of the customer calling the tracker's SIM to "ask" its location, or setting it to send updates at certain intervals, all location queries are requested through the provider's network.
Maybe i watched too many James bond movies or any of those NCIS, Law and Order Shows seeing those little wireless speakers and tracking devices attached to cars etc. Seems like one of these little tracking devices could be built into the camera and running off the batteries for power , but would stay on even if the cam is off.
Even some of the lower cost ones available to the public have "quiver alarm" (what the manufacturer calls it; vibration sensing) and "electronic lock." The latter detects if the device is removed. Some trackers can be switched between "track" and "monitor," so an attached microphone can pick up sounds near the device. Most of them available now will send a low battery alert, and some of them will send an alert if the external power is disconnected. All of those features could contribute to tamper resistance.
I think a lot of the technology is available now, but as somebody asked in an earlier thread, how much more would we be willing to pay to have it built into a cam? We haven't heard much lately about the "Live" cam (I don't recall now who makes it; Spypoint?), so I have the impression it wasn't exactly the "better mousetrap" a lot of people were looking for. Or maybe it's not on the market yet? It required a subscription, too, if I remember correctly, but it was supposed to be able to send a tamper alarm.
The two companies that make the similar-looking, kinda pager-shaped trackers also have similar model numbers. Sometimes those "102-class" trackers sell for under $100, but that doesn't figure in the cellular charges. And I don't know yet if anyone could really depend on one to help recover an expensive cam if it got stolen.
