A burglary alarm system can help protect your home against break-ins. Alarm systems typically use motion detectors and other sensors to detect intruders. The system may also include a recording of a pre-recorded message that can be played over and over again. If an intruder is not able to contact the property owner, the system can call the police for assistance.
Some high-end alarm systems connect to a central monitoring station through a wireless phone line or radio. This provides the fastest possible response to an alarm. Direct connections to the emergency service are not allowed in the UK, but they are common in school campuses that have dedicated fire and security departments.
When an alarm goes off, a digital cellular communication unit sends a signal to the central monitoring station. Once the signal has reached the receiving center, operators will verify the alarm, check the nature of the case, and dispatch the appropriate authorities. In some cases, the operator may call the homeowner directly. These types of systems are useful for medical emergencies and break-ins.
During commissioning of detection devices, the installer will set the sensitivity of the alarm. Some systems are capable of changing the sensitivity of the alarm depending on the area the sensor is placed in. They can also change the sensitivity of the alarm after the installation of the devices is complete.
A dual signaling system is a more affordable way to raise an alarm. Dual element sensors analyze signals from two different types of sensors, and then send an alarm signal when they reach a preset threshold. These sensors must be resistant to tampering.
Another type of alarm system is a “all-in-one” panel. It is an ideal choice for light commercial settings. An all-in-one system can have a siren, keypad, and other electronics included on one single unit. However, it is recommended to contact a reputable security professional to install the system and to ensure that all the required equipment is installed properly.
Alarm systems are based on the electro-magnetic field disturbance principle. They are based on the premise that a pre-set threshold causes an increase in the field strength. This is usually done by using two coaxial cables buried at the same depth.
A typical alarm system can provide protection for assets that need special attention. Examples of these assets include valuable art objects, jewelry, safes, and vaults. Other assets include filing cabinets and firearms. Security systems can be configured to automatically call the homeowner, notify the central monitoring station, or even dial the police on their own.
Burglar alarm systems can be activated by a person walking into the building, or by a loud sound. They can also be connected to external security cameras to alert the homeowner of a break-in.
In most cases, the alarm will be cut off once the user enters a security code. Alternatively, the user can contact a security company for specific information about the intrusion. In addition, the system may have a speaker phone that allows the central monitoring station to contact the homeowner to inform them of the intruder’s presence.
