I am looking for a locating/tracking product which can be used to disable and then recover an asset which has been lost/stolen.



So for example, if the asset goes outside a geo-fence then I can disable it. I considered using a vehicle tracker here as it has an engine cut-off function and I maybe able to use this.

But I also want to locate it to the nearest meter, so will GPS and GSM take me to a certain radius of the asset such as 10m/20m radius or will it pinpoint to the nearest meter? And if it's not to the nearest meter then what other product could be used to locate it to the nearest meter? If the asset is stolen then I want to be able to find it in a way which does not alert the thief. And if lost then I know there are key locating products which could be used.
