LoJack used to be the go-to company for this. No more.

Classic LoJack had good privacy. It's a box hidden somewhere in the car, with a connection to vehicle power. It has a transmitter, but normally doesn't transmit. If your car is stolen, you report this to the police, which report it to LoJack. That broadcasts an ID over a subcarrier of some local FM broadcast station. The receiver in the Lojack unit listens for those IDs, and if its own ID comes up, it turns on. It starts loudly transmitting to units in police cars, giving approximate direction and range. If you see a police car with four short whip antennas on the roof in a square pattern, that's a Lojack-equipped vehicle. It's uses radio direction finding. The vehicle box has no idea where it is. It's a totally independent system - no cellular, no GPS.

So this only tracks vehicles which have flagged as stolen. It's not constantly phoning home.

Classic Lojack is a one-time charge, with no annual fees.

The current product, LoJack AnalProbe™, which they call "Connected Car", constantly phones home, reporting your location, battery level, etc. to the mothership. There's an app to review where you've been. And, inevitably, the EULA says that Lojack may "share information with LoJack’s affiliated companies, Service Providers and/or third parties in conjunction with the Software and Services and for the purpose of providing You with any promotional offers and marketing materials as may be permitted by applicable law."

You get to pay a subscription fee for this.

Today you see four antennas on police cars for digital diversity reception, originally desirable for minimizing multipath issues but today just about required for P25 "phase II" operation of multiple repeaters on the same channel. These are usually 900MHz radios, one of the factors in the decline of traditional Lojack was many police departments shifting to 900MHz for P25 and no longer equipping all vehicles with VHF radios. Depending on the department, vehicles may not have any radio capable of receiving Lojack transponders. Whether or not they're programmed for it is also a question.

When direction finding was used Doppler DF based on multiple antennas was rare due to the high cost of the electronics package, which also consumed a lot of trunk space. Most police departments did it the old fashioned way with a handheld log periodic they waved around. Another part of the decline of the original Lojack system was the high price of providing good DF receivers to police departments, so not many had them. LoJack never got big into having their own DF "hunters" on staff like other companies using transponders did.

The issue with the old lowjack is that whilst it was better for privacy it was far worse for actual recovery.

Cars that were outfitted with low jack would have the devices removed or disabled before the tracking could be enabled and as they didn’t report their position the police would have nothing to go by.

Whilst I agree that the information sharing is pretty despicable since you are already paying for that service the new model is more useful at least in a situation where the police actually has resources for recovery instead of doing the bare minimum because most vehicles are insured.

There probably is a market for a solution that would be more reliable than an airtag but one that you can control.

One can probably build one fairly easily with a low power SBC with cellular capability and one of those IOT global sim plans.

I assume the "LoJack Inside" window sticker is the main technology you really want? Suggest the thief go steal a different car?

The first one is... incredibly convoluted. Like reaching your right arm over your head to touch your left esr (try it!). The second one sounds like it sucks.

With the pay-once AirTags you can just find the car thief yourself and shoot them.

Wikipedia:

"In March 2016, the company was acquired for $134 million by CalAmp, an Irvine, California-based provider of Internet of things (IoT) software applications, cloud services, data intelligence and telematics products and services.[4]

In March 2021, the vehicle intelligence company Spireon announced it had acquired the LoJack U.S. Stolen Vehicle Recovery business from CalAmp, joining LoJack users with "nearly 4 million active subscribers from over 20,000 current Spireon customers".[5]

Under Spireon, LoJack technology moved from RF-based location to GPS and cellular-based technology, growing availability of the solution throughout the U.S. and Hawaii and expanding the solution from only stolen vehicle recovery into connected car technology for both dealers and consumers."

> If your car is stolen, you report this to the police, which report it to LoJack.

By which time it is already chopped up for parts or, in the case of places like Phoenix, is already in Mexico.

I used to have a roommate who grew up in NYC, had a somewhat dubious past and was talking about LoJack one day. He claimed it doesn’t work well enough in dense urban areas to get a precise location fix to actually impede theft. IIRC they would have enough time to disable it as long as they stayed around tall buildings. Something like they would park the car in an alley between buildings and find the LoJack before doing whatever with the car.

I’ve known a few youthful car thieves over the years with some interesting stories.

Just a thought here... Why not just write a simple script that collects GPS location, host it on a private server, point an old Android phone at that page, and wire the phone under the dashboard?

do you know if the legacy system is still in use?

my first 'nice' car had lojack installed in it. i remember it was about $200, and that's all, but this was 10+ years ago. i wonder if it's still out there...

Outstanding name! Their marketing team has a wicked sense of humor.

Wow, the police allowed their entire fleet of vehicles to be used by a private company? And taxpayers considered this ok and not blatant corruption?

Capitalism, you scary.
