What Is A Varifocal Security Camera?
One of the best values in security cameras are those equipped with a varifocal lens. These lenses come for a variety of camera styles with the two most popular choices being very-focal lenses on dome cameras and box cameras.
Varifocal Lenses Are Great For Businesses That Plan to Expand
These lenses are perfect in many situations. The first situation is a business that plans to expand to a new location someday. When a camera is equipped with a varifocal lens, then the business owner can easily move the camera to a new location. Adjusting the camera at the new location can easily be accomplished just by adjusting the focal length of the lens.

Many people find night vision security cameras to be the answer to their home and business needs. If you are considering a purchase of a night vision security camera there are several factors to keep in mind.
Factor 1 Image Enhancement
Night vision security cameras work in two ways. The first is by image enhancement. The security camera collects very minuscular amounts of light that are present in the environment and amplifies them so that the viewer of security camera footage can see the image.

IR Security Cameras See What No One Else Can
A common misconception about IR security cameras is that they somehow send out infrared scanning waves. Thermographic cameras work on essentially the same principle as traditional photographic cameras. This means that IR security cameras are every bit as flexible as regular CCTV surveillance cameras. Generally, they’re used to extend the range of surveillance equipment in low light areas. There are countless models available, and each of these is best suited for use in a particular type of installation. That being said, they still use a type of photography, so IR security cameras are just as safe to use as any other type of surveillance camera.

A wireless night vision outdoor security camera is a digital video camera with highly specialized features. Modern technological advancements have made these specialized features available at a very affordable price while offering high quality video images.
Outdoor security cameras differ from their counterparts the indoor security cameras, in that they are enclosed in a case that protects them from weather and environmental elements. Wireless night vision outdoor security cameras are often rated according to the protection that they offer. This protection is often described using an International Electrical Code standard called an Ingress Protection rating, International Protection Rating, or IP code. Most wireless night vision outdoor security cameras have an IP code of IP66 or IP67. IP66 means that the camera is dust tight and that water from powerful jets in any direction will have no harmful effects on the camera. IP67 means that the camera is dust tight and can withstand being submerged in water up to 1 meter in depth.

Thanks to relatively recent technological advances in electronic imaging, night vision security cameras are becoming one of the most popular types of security/surveillance cameras for businesses and residences alike. Before purchasing a night vision security camera it’s important that you are familiar with some of the terminology and functions associated with this specialized type of security system.
Most Closed Circuit Television or CCTV cameras today are digital cameras. Basically, they take pictures or video much the same way as a personal digital camera or camcorder. These cameras operate by allowing light to penetrate through an iris or variable opening, a lens, and then strike a charged coupled device or CCD.
