What is Automatic Driver Recognition?
The Vodafone Automotive 4822 supports ADR card security
The new ADR Card from Vodafone Automotive is designed to work with the 482X series of alarms. It has a amber LED so it is easy to tell the difference over the old ones.
Built-in Motion Detection
The first notable difference over the previous ADR card is that it now has motion detection and a sleep mode. If the card is left motionless for 60 seconds it will turn off until it moves again. This is to help protect against relay attacks.
How does the ADR Card work?
When the alarm is disarmed with the remote the alarm will look for the ADR card. Once detected it will disable the following features depending on which are programmed to be active:
- Passive Crank Immobilisation
- High Security System
- Anti Hijack
The ADR Card can also arm or disarm the alarm by pressing the button, but under normal circumstances the card does not have to be accessed as the arm/disarm commands are set via the vehicle remote/keyless entry system.,
What sort of range does the ADR card have?
Normally about 3 to 5 meters, but I have had over 10 meters on the test bench. It really does depend on how where the alarm is installed in the vehicle and how many obstructions are in the way.
How long to the batteries last for?
The ADR card uses a CR2032 battery. It is recommended that the battery is changed every 12 months.
