Alarms
There are generally two types of alarms:
* Audio-only alarms, making a loud noise when activated;
* Monitoring Systems – when activated the alarms to notify a remote monitoring station, or monitoring station. ” The monitoring station then notify a person who has been nominated by the head of the family and possibly the police. Naturally, these systems are more expensive because, in addition to the installation and maintenance, there will be a fee for the monitoring service.
audio-only alarms will have a strong deterrent effect – a thief is less likely to enter a house with an alarm and is unlikely to remain if the alarm is sounding. However, the false alarm is a common feature of modern life that could be ignored when there is a real incident.
monitored alarms offer an additional level of security, attendance will be sent to the property. The police just monitor alarms are installed by a company that complies with the Association of the security policy of Chiefs of Police “- and there are very few companies that meet the rigorous standards established by the police. The police, however, still respond when notified that the alarm is sounding for someone who has heard.
Installation
Many of the most sophisticated systems will be installed and maintained by a specialized company. Before choosing a business, householders should check the credentials of the company and ensure that the equipment installed meets British or European standards. Families should never agree to have a security system installed by a company that uses cold calling or canvassing techniques.
The company installing the system – or simply provide a quote – should carry out a full risk assessment before recommending a system adapted to the needs of the household head. In some cases, insurers require a particular type of security system and the company to carry out risk assessment must incorporate these requirements in their recommendations. Even if an insurance company has demanded that a security system installed, sits on is likely to result in lower insurance premiums.
Some types of alarm can be installed by households. However, police do not recommend it as the head of household is unlikely to have any real knowledge of their security needs and can not set the alarm properly.
Alarm sensors
Alarms depend on sensors to activate audible or remote system:
* Motion sensors – are usually passive infrared devices that activate an alarm when motion is detected in the area they cover. They may also be ultrasound or microwave devices;
* Magnetic sensors – these are activated when the magnetic field between the devices is broken by someone or something moving through it;
* The perimeter devices – these devices can be left on when people are using the room or area they cover and activate the alarm if, for example, the glass is broken.
CCTV
Housing and its environment can be monitored by CCTV. The warning signs currently in use may be sufficient to deter opportunist thieves who prefer not to have his face on camera. These systems can be controlled from inside the home or remotely by a security service.
Electronic Entry Systems
These are most likely to be used on floors where residents will have to open the door to people that are not visible to the occupant. These may be just voice or video, and give the family an opportunity to verify the credentials of the person calling before deciding whether to let them people living in houses with large gardens may find that an electronic gate combined with a control system remote entry will give a sense of security.
