The need for security systems has increased rapidly with the increasing number of criminal activities at various places including homes, workplaces and public spaces. Whether yours is a small business, federal office, school, shopping mall or a home, you need to protect it from harmful groups like robbers, vandals, burglars, etc. Moreover, you also need to monitor the movements of employees, children, visitors and trespassers alike. If you have a plan to install surveillance cameras, consider the following points before investing in them.
Camera for indoors or outdoors
The first thing you need to consider is whether the cameras will be used indoors, outdoors or at both places. Indoor cameras are useful for surveillance of the inner space in a facility. You can install these cameras even for a single room depending upon the need like monitoring the valuables, inventory, people, etc.
Outdoor cameras are installed at the points of entry and exit, all around the buildings, on the streets, etc. Cameras designed for indoor use may not work for outdoors. You should choose cameras that are weather-proof and vandal-proof if they are to be used outdoors as there will be high risk of damage.
Day or night use
When choosing a surveillance camera, you need to consider the camera’s sensitivity along with the amount of light reaching the surveillance location. If the sensitivity of the camera is high, it requires less light to produce clear images.
If you are planning to use the cameras during night, you need to make sure that the sensitivity of camera is high enough to produce images with recognizable details even if the amount of light available at the scene is less. For surveillance at night, you can use infrared cameras. These cameras can work even in poorly lit conditions. The camera works like an ordinary camera during the day and at night, it uses infrared light (which cannot be seen by human eye) to illuminate the place.
Install a camera with good resolving power. If the resolution of the camera is low, the image given by the camera is not distinct enough and is thus, blurred, making the image hard to identify. The greater the resolution, the distinct and clearer the image is.
Determine the amount of area that you are planning to put under surveillance. The number of cameras you need for a particular area depends on this factor. Thus, if it is for a huge parking space, then the camera should have high coverage and greater resolution (the resolution power of a camera decreases as the extent of area covered increases).
