The cameras usually contain a group of infrared Light Emitting Diodes or LEDs that shed infrared light on the target area. However, when there is no longer enough visible light, these cameras switch to infrared mode.

Night vision infrared cameras can produce a high quality color video image when there is enough visible light. 002 lux which is equivalent to the amount of visible light available on a clear, moonless night. These cameras are often rated in “lux ” a unit of measurement of the intensity of light. Wireless security cameras that contain these specialized highly sensitive chips can be either day/night vision cameras or night vision infrared cameras.ĭay/night vision cameras can produce a high quality color video image in conditions with very little visible light. The electronic sensor chips that are used are either a Charge Coupled Device or CCD or a Complimentary Metal Oxide Semiconductor or CMOS. Wireless security cameras that are used with a computer monitor can have highly sensitive image chips that allow it to work in different lighting conditions. If an object is blocking the LOS, the range will usually be reduced, depending on the makeup of the object.

Some wireless cameras may have specified ranges of a mile or two. In other words, the LOS range means the maximum distance the camera can be separated from the receiver provided you could see the camera from the receiver’s position or you could see the receiver from the camera’s position. The camera transmits its image using the 2.4 or 5.8 GHz radio band technology and has a Line Of Sight or LOS range.Ī LOS range means the range listed for the maximum distance between the camera and receiver is if there is nothing blocking the sight between the two. This can be used in offices, retail stores, schools, in the home, as baby cams and so on. Wireless indoor cameras are great for use anywhere that cabling may be difficult or unsightly. Outdoor wireless security cameras are excellent for monitoring area perimeters, driveways, industrial structures, entrances and exits, and many other areas. Outdoor cameras normally provide protection from dust, water, weather and other environmental elements. Outdoor cameras are basically indoor types with a protective cover or case. There are many varieties of wireless digital video cameras. The security system works in the following manner:ġ) The digital video camera captures video images.Ģ) The digital video images are transmitted to the receiver by the camera using the built-in transmitter and on-board antenna.ģ) The receiver accepts the cameras transmission and provides the necessary out connections to a computer monitor.Ĥ) The computer monitor is used to view the images sent to it by the receiver. A typical wireless security camera with computer monitor setup includes three major components:ġ) The wireless digital video camera or cameras How do wireless security cameras used with a computer monitor work? Let’s talk about what it is first, and then we’ll discuss how it works. Thanks to innovative advances in both computing and electronics, wireless security cameras can be used just about anywhere and can be viewed using a standard computer monitor. Wireless security cameras with computer monitor can be used in residential applications as well as business or industrial applications. Wireless security cameras with computer monitor is basically a security monitoring system within itself.
