The sensor is used to detect people or vehicles on the driveway and the receiver is the device which alerts the user or owner to this detection. Wireless driveway alarms consist of three components, the sensor, receiver and a transmitter which sends the wireless alert signal to the receiver. [citation needed]
Due to the low range, a tagged entity will be identified by only a few close, networked receivers. An identified tag must be within range of the identifying reader, allowing a rough approximation of the tag location. Advanced systems combine visual coverage with a camera grid with the wireless coverage for the rough location.
Driveway alarm systems can be combined with most security and automation systems. They are designed to alert residents to unexpected visitors, intruders, or deliveries arriving at the property. Types of driveway sensors include magnetic and infrared motion sensors. Driveway alarms can be found in both hard-wired and wireless systems.
Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs). In the most widely used mode, transmission power is limited to 2.5 milliwatts , giving it a very short range of up to 10 metres (33 ft).
Z-Wave is a wireless communications protocol used primarily for residential and commercial building automation. It is a mesh network using low-energy radio waves to communicate from device to device, [2] allowing for wireless control of smart home devices, such as smart lights, security systems, thermostats, sensors, smart door locks, and garage door openers.
Typically, analog wireless has a transmission range of around 300 feet (91 meters) in open space; walls, doors, and furniture will reduce this range. Analog wireless is found in three frequencies: 900 MHz, 2.4 GHz, and 5.8 GHz. Currently, the majority of wireless security cameras operate on the 2.4 GHz frequency. Most household routers ...
