S7 is the standard requirement for a Thatcham approved tracker. With 24/7 monitoring from an approved control room, staff are ready and able to direct Police or other recovery agents to the location of the stolen vehicle. Utilising real time tracking showing a minute by minute location of the vehicle.
S5 has all of the benefits of the S7 systems, with the addition of ADR (Automatic Driver Recognition) by the use of a small fob that can be attached to the keys of a vehicle. If the ignition is started without this fob present a notification will be sent to a control room and staff will work to identify whether the vehicle has been stolen and will work directly with the police to allow recovery of the vehicle.
The S5 Deadlock is the top end of tracking, with the additional ability for the vehicle to be remotely disabled and immobilised. Whether this be not allowing the vehicle to start due to the lack of fob being present, or through an app whereby the engine can be remotely immobilised until a second command is issued to allow the vehicle to start.
As above with the Deadlock pro, but with the addition of OBD blocking too, so that the vehicle cannot be remotely accessed and have new keys paired to the vehicle without the owners knowledge.
