A security camera’s most important part is the security camera lens. The lens is what determines how sharp and clear the images on a CCTV camera can be. It also decides how much or how little the security administrators will be able to view at any given time.
There are some lenses that are capable of giving a better, clearer look. Some lenses have special zoom functions that give the user a chance to zero in on an item or detail being captured at that place. A CCTV camera can use a telescopic lens to investigate far side of a room or area. It gives the clearest image over different distances from the camera.
Another aspect of the CCTV security camera lens is its use indoors or outdoors. Many cameras that are to be installed outdoors will demand a different set of features to suit different environments. To keep a camera fully functional outdoors, it must be able to keep running despite shifts in temperature, humidity and light. A shift from day to night can cause glass to fog, or resolutions to drop. For this, there are some lenses that adapt to the environment. These cameras have lenses that keep moisture from sticking to the glass. This ensures that it will not be susceptible to a certain threshold of frost and condensation, which would cause it to lose image clarity.
This need not cost a lot of money. Instead of buying new expensive cameras for a system, most opt to upgrade the camera lens and attach it to a simple CCTV camera.[ad_2]
