LoJack

[David_Kb7uns]

Another problem with LoJack is the law enforcement agencies in your area need to have cars with the LoJack receivers in them and not every agency has them.

Look with police cars that have 4 18 inch antennas in a square pattern on the roof.
If they have 3 13 inch antennas in a triangle that is for the ETS Pronet bank robbery systems.

LoJack FAQ:

It is based on wireless Radio Frequency technology. From ground or air, police can track the silent signal from your LoJack whether it is in a garage, an underground parking facility, or in a warehouse. This differs from most GPS-based tracking systems, which require direct line-of-sight to the sky.

Frequently Asked Questions about the LoJack Stolen Vehicle Recovery System

That was what I thought too. I'm inclined to still get the LoJack.

Not to confuse anybody, but if a thief has any idea about LoJack, he would quickly move it to a building built like a Faraday cage. We used a cage like this in the Navy to repair and tune navigation equipment. No signals in or out. He could then go inside the cage and seek out the LoJack. He would look for a frequency around 173.075 MHz. VHF band.

The thief's other option would be to leave the machine at another location that he could watch.

Probably should do both, use LoJack and disable the engine from starting.

Did you know that if you put your cell phone in one of those silver metal foil bags, you can not receive calls or be tracked by GPS.

That assumes the thief is smart. Seeing as how he's already decided to steal something instead of work for it, we can generally eliminate that possibility. LoJack claims a 98% recovery rate, so we can start with the assumption that only 1 out of 50 thieves have a clue.

I get the exact same results by turning it off. Cheaper, too.

It's not the smart one's I'm worried about, that's what my insurance is for. It's all the others. I do think that if I decide to get it, placement will be of importance so that it's not found either quickly if at all. I have an email into them to ask how it is wired into the system, suggested locations etc.

Auto theft detectives like Lojak. Good enough for me.

That explains why I can't make or receive calls in my house - it has foil faced foam on the inside as a vapor barrier.

this is not accurate

phones like iPhones still connect to the network when they are powered off. This is considered a "Feature" so that when you power the phone on the system already knows what tower to connect to and has messages already downloaded to the phone makeing access times quicker.

because of this your phone is still "tracked" when it is "off". You can remove the battery from the phone, but alas iPhones (and most other "smart" phones) do not allow this.

So thus the foil bags are the best way to keep "them" from spying on you as it does block all signals.

It's entirely accurate. I don't have an iPhone.
