How Do Alarm Sensors Communicate?
Alarm sensors communicate with security panels using a variety of different methods. The method that is used will depend upon the type of sensor. Some are wireless, while others must be hardwired directly. Most sensors use wireless RF signals, a hardwired connection or WIFI connectivity.
Today, many users prefer the simplicity and convenience of wireless security sensors. These devices communicate primarily using RF signals. The frequency that is used will depend largely on the company that made the sensor. For example, most Honeywell 5800 Series Sensors communicate at a frequency of 345MHz. This allows them to be readily used with both wireless Honeywell systems and 2GIG panels. However, since Qolsys systems communicate at a frequency of 319.5MHz, they will be unable to work with these systems. Luckily, Qolsys makes their own lineup of wireless sensors that work at the 319.5MHz frequency. Most hardwired systems, such as Honeywell Vista Panels, can also interact with wireless sensors, but a wireless receiver will be needed.
There are also wireless sensors that connect with a panel using WIFI. The Honeywell SiX Series of sensors is known for using this type of connectivity. These sensors are exclusively for use with the Honeywell Lyric Controller, making them an excellent complement to this top-quality security system. One of the best aspects of these sensors is their incredible range, which allows them to operate at a distance of up to 300 feet away from the Lyric Controller.
Some wireless sensors feature methods of encryption to help prevent them from being taken over by hackers. Encrypted wireless sensors require the security system to send a signal back to the sensor in order for any command sent by the sensor to go through. By using these methods of encryption, these sensors are very secure, making it incredibly difficult for tech-savvy intruders to take over the sensors and cause serious problems. Both the Honeywell SiX Series Sensors and the Qolsys S-Line of sensors use some type of encryption.
Finally, there are also wired sensors that communicate using a hardwired connection. While they offer great performance once they have been set up, fishing the wires through the wall to the panel can be inconvenient or challenging. However, if they are already installed and in place, they can usually be carried over to a new security system when an upgrade is being made. Hardwired sensors are usually hardwired directly onto the circuit board of a hardwired system. They can also connect with a wireless system by using a hardwired to wireless converter, such as the Honeywell 5800C2W.
