Infrared Security Systems

Infrared catches thieves red-handed

When security of a business is at stake, things can't be left to chances and everybody cannot be trusted. In a business house, there is constant movement of people from within or outside. Anyone of these could be a potential threat to the security of the office. It is for this reason that office security systems must be installed including cameras, hidden and visible, and alarm systems be launched for cases of emergency.

The security systems are very scientific and are based on technology brought into form through extensive research and development. Often the security systems employ the use of infrared or IR radiation that is actually an electromagnetic radiation of wavelength longer than the visible light, yet shorter than microwave radiation. So, it proves to be useful but causes no harm to the area or environment in which it has been installed or to the people there. The main use infrared of imaging and photography through infrared ray cameras is to capture miscreants or to protect valuable objects such as those kept in a museum or jeweler's shop.

Besides in homes, or business establishments, largely police and military forces use Infrared security cameras. The edge they have above the regular security cameras is that they can capture a quality frame even in the dark of night preventing robbers from intruding into your house or office to purloin important documents or precious objects.

By capturing the body heat of the visitor to the field infrared cameras are able to capture the image even in the dark. There are also a variety of infrared cameras that are activated automatically on being triggered by heat that their sensors catch and they begin to roll and capture the view. Added features in the system help make the security system even more reliable, for example, on turning on infrared cameras automatically switch on an alarm system and could even wake up like an alarm clock does. They may even automate calling the number of the police station to inform about any trespassing.

Detectives are always using the infrared technology for their investigation and often carry infrared cameras in their pocket.
