Sometimes a particular security camera is tasked with covering a large area. Examples of this type of scenario include: Parking lots, walkways, concourses, air port terminals, and so forth. Not only are these areas large, but they also include depth which needs to be accounted for when it comes to security footage. If a criminal is caught on tape, but is too far away, then the footage may not be able to paint a clear picture. This is why it is an excellent idea to equip your security cameras with Auto Iris Varifocal Lenses, which you can find at SpyTown.com.
What are Auto Iris Varifocal Lenses? These are lenses that give you a sense of diversity due to the variable focal lengths of the lenses themselves. This means that if adjusted properly, your cameras will always be able to give you the footage you need to guarantee the proper security coverage. The unique feature about this type of lens is that they have the ability to adjust automatically as they start to pick up movement in the area that they cover. If any object or change in the intensity of light should occur within sight of these lenses, then they have the ability to change their own settings so that your footage remains clear.
