Asalam-o-Alikum brother,
I have bought the system in 10,000 Rs. It has following functions (which I have explored till now)
1) Notification, if some one hits the ride. A hammer is shown on the screen of remote and it vibrates together with beeps.
2) Notification, when any door or boot is opened. The car represented in the display shows the opened door. It beeps and vibrates.
3) Other things are common like locking/unlocking/muting/location check/clock etc.
4) Display shows the amount of signals received from ride just like a cell phone. More you move away, less are the signals.
5) The range is almost 800 Meters in open atmosphere. In buildings it works around 400 meters, sometimes even less. But the manual shows that it can go up to 3000 meters. It feels like an exaggeration but it also has an extension antenna with it. That antenna may take its range to one Kilometer (might). The installer told me that installation of antenna doesn't make much difference, so I decided not to install it.
Best of luck bro,
regards
