Security alarm systems have evolved over the years from the simple switch-siren setups to the more sophisticated wireless systems of today. From the basic motion-detecting switches attached to doors and windows that were widely used in the past, today’s security systems integrate various self-powered sensors that use infrared, laser, thermal, and other technologies.
One of the major advances in security systems is the use of security cameras (also called video surveillance cameras). Security cameras are staple components in the security protocol of airports, malls, banks, hotels, and convenient stores.
Based on statistics, security cameras help in crime prevention by driving off most burglars and intruders and by gathering solid evidence of an ongoing crime.
In fact, video surveillance cameras have been instrumental in the arrest and eventual conviction of many burglars, armed robbers and other criminals.
With the demand for home security products on the uptrend, domestic use of surveillance cameras and closed-circuit television (CCTV) is also becoming popular among homeowners.
Home security cameras
Security cameras that are integrated in home alarm systems are in common use today. Some video surveillance cameras are wireless, enabling property owners to install them anywhere in the property. This means that cameras for alarm systems may be installed both indoors and outdoors, effectively extending the coverage area of the security system.
Generally, video surveillance consists of small cameras with various features that can be remotely controlled using computers and smart phones. Additionally, home security cameras function as effective monitoring devices that provide real-time glimpses of the property even when property owners are away.
Home security cameras are easily setup and easy to conceal. Hiding security cameras is important since criminals are known to destroy video surveillance equipment first, among the other things they damage when attempting a robbery or other crime.
In order to help property owners conceal security cameras, many manufacturers build the cameras in small packages or disguised as common objects such as circuit breakers, lights, and different home or garden décor.
Features and capabilities
Primarily, cameras used in home alarm systems function as real time monitoring devices. Security cameras can also be configured to record images and video of a particular location in the property 24 hours a day or at any time desired by the homeowner. Some security cameras are equipped with night vision, allowing them to monitor and record even at night.
Most security cameras that are fully integrated in security alarm systems may also be programmed to immediately turn on in order to monitor and record events at specific locations in the property where suspicious motion or heat has been detected.
Advantages
Cameras for security alarm systems can be easily installed since they generally do not require extensive wiring. In addition, security cameras are relatively inexpensive add-ons to an existing home security system considering the whole range of benefits they deliver. Configuring security cameras via software that comes with the package is also easy to accomplish, allowing homeowners to tweak the surveillance features in order to do a number of tasks:
- Focus on locations that have higher security risk
- Save on disk space by setting up how or whether videos are to be recorded
- Save on power by specifying the time cameras are to be turned on
