Hmm, yea the underground blocked signal thing sucks. and i've read some vans have "scramblers/blockers" if that is the correct term.
Yep, that's correct. Most of them are GPS blockers (under $25, just plugs in your cigarette lighter socket

), and I was hoping my device could run on Wind's AWS 1700Mhz network (none of the blockers really do that freq) but no go, none of my peeps in China knew what 1700mhz was, so it'll be using a Rogers sim card ($85/yr for unlimited texting). The device is quad band so I hope that if someone is running a jammer that it at least gets signal from something

If GPS signal is blocked it can use cell tower triangulation to calculate its position. Not SUPER accurate (usually within 300ft depending on how many towers in range).
(maybe even sound, to hear thieves talking, maybe stupid enought to use their names when talking)
Just FYI, you can't record audio without posting lots of signage up (would probably have to be at condo parking entrance and all around your parking spot) and even then the police using it or using it in court is very unlikely
My security device has a high gain microphone for when you tell it to "dial 911". It'll tell the 911 operator "I'm a motorcycle and I've just been stolen. I'm currently on King St. heading east towards Simcoe St. at 67 kph, in the town of Oshawa. The registered vehicle owner is So and So and his phone number is xxx-xxx-xxxx. Please begin tracking this phone and I will now enable the high gain microphone so you can hear the thieves. If you wish to hear my current location and direction hit 2 at any time. Live mic now..."
I tested it with the durham regional police and they were able to track it after only about 10 seconds of it calling 911. I'm not sure they'd ever do anything or if they even care, but heck, it's worth a shot
You can track it live from any smartphone or computer, overlay on google maps including last known location (in the event the device is "disabled").
Works freakin sweet so far, just need some software stuff finished like the GeoFence set up, be able to text it "arm" and "disarm" commands to enable and disable the geo fence and tilt/motion/shock sensors and also get the cameras working (they work when the cable is 1" long, but over 1ft and it gets no signal from the camera

). There's a camera that goes on dash looking back at the "rider", and one under the tail looking to the rear. If you want to get funky you can tell it to record the dash cam in 1080p and the rear cam in 720p at the same time then download the video to a laptop via USB after your track day is done

lol.
