Sensor units that incorporate two different type of sensors are called dual technology
sensors or dual techs. These home security sensors are an increasingly popular
type of sensor that combines the penetration capabilities of microwave sensors
and the heat sensing capabilities of infrared sensors in one unit. Some units
can be adjusted to tailor the security coverage to what's required in a home
installation. There are many technological solutions being introduced all the
time including digital security. Also, check out digital motion sensors. |
