Won’t it be nice to have paparazzi take care of your home in your absence? Taking clear shots of every ‘star’ that ventures into your apartment? That certainly won’t be a bad idea especially now that almost everyone is under the limelight of an attack!

Home security cameras are such great paparazzi as they tend to unveil events that happened during one’s absence from home. In some cases, they could even deter intruders depending on their location round the house. They come in many sizes and have unique ways of functioning. An example is the motion sensor camera. This triggers an alarm when there is a change in the wavelength of two infrared lights, one of the camera and the other of a living being.

Every living being is said to emit infrared energy and humans emit a wavelength of nine to ten micrometers. The motion sensors of such cameras are set to pick up wavelengths of eight to twelve micrometers. Therefore, the difference causes the sensors to react by triggering off an alarm.

Contrary to the function of the motion sensor camera, night, vision, camera, use infrared emissions to reveal images in the dark.

One of the most common ways of recording crime is by the use of hidden cameras examples of which are pin hole cameras, board cameras, which are made of a small PC board with an in-built mini camera, standard surveillance cameras, water-proof hidden cameras and water resistant cameras.

In a real-life story of a man who tried to kill his wife in order to make claims to her property, the woman installed one of such hidden cameras in a flower vase in her kitchen since she believed that the man added some poisonous substance to her drinks any time he opted to serve her. Luckily, he was found out and arrested.

Hidden cameras do not only check intruders but also insiders in the home such as the nurse caring for the old patient or the babysitter seeing to the child.

One major example of hidden cameras is the standard surveillance system with digital video recorder kit. Often, a total number of eight to thirty two cameras make up the surveillance system in addition, to the digital video recorder. The digital video recorder, also known as the DVR contains a hard disk that captures scenes from the various cameras of the system. This allows an elaborate viewing of events. This surveillance system is popular in high-security areas such as banks or military stations. However, it can be used anywhere, in homes, offices, churches, schools or shops.

The choice of a home security camera depends on one’s personal need and the environment (reference from an article on the VFM store). For instance, in a place of low to little light intensity, using a Black and White camera would be most appropriate. Cameras may also be wireless or wired.

Some of the best camera manufacturers are Bosch, Veilux, Axis, and Hikvision.
