Gemini have released an ADR alarm very simular to the Cobra 4600 series. The ADR card which sits on your vehicles key is a little more secure in the way it shuts down after 5 mins of no movement, this means there is no way the signal could be amplified or changed in order to trick the alarm to disarm. The Gemini is very universal due to it having an onboard full can-bus index meaning it can be programmed to many different vehicles made after 2005.
The alarm will arm and disarm from the original remote control meaning you lock the vehicle and the alarm will fully arm and unlocking will make the arm go into a pre-disarm state until the secure ADR card is in range. The alarm also features 1 touch key which allows the user of the vehicle to disarm the system in the event of the ADR card battery going flat.
The siren is very effective sounding at 118DB when triggered. The system also flashes indercators on alarm sounding for a visual warning.
