The tracker will not send an alert to the control centre and alert you if your particular model of tracker has the facility until the caravan is being towed, if someone enters the van to steal items inside, the tracker will not alert and the crook can also spend time trying to find and disconnect the tracker before towing the caravan, most reputable tracker systems will de activate the tracker signal to the caravan owner and only have the signal sent to themselves so they can update the location to the police, they don’t want owners tracking the caravan due to the unknown person or persons who have stolen it reacting violently should the owner try to stop them, the signal is not sent first hand to the police, it’s location is forwarded by the tracker company, the trackers fitted by Tracker Network is to my knowledge the only system that the police actually track themselves.

If you have the Phantom tracker which is proactive, if any one interferes with the caravan i.e. enters the caravan the call centre will be alerted. If they remove the tracker or the battery the call centre are alerted.
Phantom Tracker work in conjunction with the police like the other Tracker Retrieve as both are recognised by the police.
It would have to be a very foolish persons who tries to apprehend the thieves due to their tracker notifying them only of the theft. Also unlikely the police will respond to such a call from a member of the public using and unrecognised tracker which is fair enough.
