The Vanguard alarm can integrate with your vehicles own remote. It also comes with an extra remote fob which can be used as a spare and it is used for the Night / Pet mode features. 
Pet Mode/Night Mode
Pet mode, or Night Mode, allows you to keep your door and window sensors armed whilst deactivating the motion detectors. This allows your vehicle to remain secure whilst preventing accidental alarm activations during the night or when you leave your pet unattended.
Wireless Sensors/Door Sensors
Your vehicle will be protected by a series of sensors around the key weak points on your vehicle, or the most common entry points for thieves, such as windows and doors. More PIR or wireless mag door switches can be easily added for extra security. The alarm will accept up to 55 additional sensors.
