Burglar Alarms in Coventry

Coventry Business finder

Burglar (or intrusion), fire, and safety alarms are electronic alarms designed to alert the user to a specific danger. Sensors are connected to a control unit via low-voltage wiring or a narrowband RF signal which is used to interact with a response device. The most common security sensors are used to indicate the opening of a door or window or detect motion via passive infrared (PIR). New construction systems are predominately hardwired for economy. Retrofit installations often use wireless systems for a faster, more economical installation. Some systems serve a single purpose of burglar or fire protection. Combination systems provide both fire and intrusion protection. Systems range from small, self-contained noisemakers, to complicated, multi-zoned systems with color-coded computer monitor outputs. Many of these concepts also apply to portable alarms for protecting cars, trucks or other vehicles and their contents (i.e., "car alarms"). In Coventry burglar alarms are sometimes referred to as alarm systems.


Burglar alarms (or perimeter security systems, perimeter detection systems, Perimeter protection, intrusion detection systems and many more terms for the same thing) are divided to two main fields: home burglar alarms and industrial burglar and perimeter intrusion detection.


In the field of industrial security systems, the methodology of protection is quite different. First is to detect, second to delay, and third to alarm. Industrial alarm systems are designed as an integration of several sensor systems. The most important for big facilities would be the outer fence on which a sensor is placed. It would detect and delay the intruders before they even reach the building itself. As described below, there are a number of different fence mounted sensors, each with its own pros and cons. Other than the fence mounted sensors, there are also buried perimeter sensors that can be put on top of a wall or buried underground to create a hidden defense line. This only allows the security system to detect an intruder, but does not delay them. Another choice for detecting is Closed Circuit Television (CCTV). A guard can watch the screens or video motion detection software act the part. In any case CCTV is ineffective as a standalone sensor because it’s affected by weather conditions as cameras cannot see in heavy fog, rain and snow. The last line of protection is theCoventry building itself. It can be protected by infrared sensors, microwave sensors, smart locks and magnetic door sensors.
