Everyone is quite clear about the reason for installing a security camera in homes.
They are installed to protect your home from potential burglary and to catch the culprits if such an event occurs.
They are very useful in monitoring and recording almost everything that the person enters your home is doing.
Earlier, security cameras were seen only in banks and department stores.
But now with the improvement in technology it has become very cheap to afford security cameras and recording devices for everyone.
Cameras can be classified into many categories.
Based on their functionality they can be classified into Bullet, dome, c-mount, and infrared cameras.
Each of these cameras differs in their functionality and application.
One should be choosing them based on their needs.
While choosing a camera, one has to take into consideration about factors like where you use the camera i.
e.
inside the building or outdoors, during night, day, or round the clock etc.
Commonly bought security camera unit is the bullet styled ones.
This is provided with all the essential accessories needed for round the clock surveillance.
They come with preinstalled weather shield and wall mount units.
This allows easy installation of the unit in homes.
Most security cameras are having a fixed focus 4 mm lens.
This provides the widest angle of 70 degree view without distorting the picture.
Cameras are available in back/white and color formats.
Higher resolution color pictures will give you a better view and picture.
Another camera to consider for installing in your homes is the infrared camera unit which can capture pictures in dark.
It consists of an infrared sensor surrounded with infrared light.
This gives a clear view of the things at a distance of about 25 meters.
This distance can be further increased if there is a small amount of light available.
Infrared cameras works best in indoor conditions.
For outdoor use we will have to install a day/night camera with a high sensitive sensor capable of capturing light in low lit conditions.
C-mount cameras are those security cameras which provide the option for zooming into the frame.
This will be having changeable lens system and vari-focal lenses allowing us to adjust the focal length.
Dome cameras are some of the most durable cameras available for us to install in our homes.
If you are not capable of buying these high end devices, you can always buy and install dummy cameras which will scare away most burglars.
