Providing your own home security in the form of digital video camera systems is becoming one of the most popular methods of residential security and monitoring. In addition, wireless home security cameras and monitors are become increasingly popular as well because of their versatility in application, ease of installation and operation, and reasonable pricing that makes them affordable for almost any budget.
What is the difference between “wired” and wireless home security cameras and monitors? Basically, “wired” digital video home security cameras use some sort of cable, usually an RG-59 coaxial cable to transmit their video signals to the monitors and/or Digital Video Recorders or DVRs. This cable is similar to the same cable used by most cable television companies. Although professional installers normally mount the cameras and run the cables using the least obvious arrangements, some homeowners may find the cables a bit too obtrusive, especially if they install the cameras themselves and use a different method.

Visibility of the cable isn’t the only reason for using wireless home security cameras and monitors. Sometimes it may be necessary to mount digital video security cameras in locations that may be difficult to provide cable to or in areas that are so far apart that it is easier to use a wireless system instead. For example, many complete home camera systems are used in rural homes that may contain lots of acreage and additional detached buildings such as garages, shops, or barns. If these buildings are located a significant distance from the home, cabling may seem impractical so a wire home security digital video camera is used instead.
One specific application of wireless security cameras and monitors is when they are used as baby monitors. Wireless digital video cameras can provide you with the peace of mind of monitoring your baby 24/7 and make great baby monitors. The digital video camera that is used for this purpose is usually a wireless night vision infrared camera and monitor system.
Infrared cameras used as wireless home security cameras and monitors, especially as baby monitors, are extremely popular and useful. The camera contains one of two special electronic sensor chips, known as a Charged Coupled Device or CCD or a Complimentary Metal Oxide Semiconductor or CMOS. These chips are sensitive to infrared radiation in the near infrared spectrum. This infrared radiation or “light” can be seen by the sensor chip (and therefore the camera) but cannot be seen by human eyes. That’s why infrared digital video cameras make great baby cams!
Infrared wireless home security cameras normally have an array of infrared Light Emitting Diodes or LEDs that surround the camera lens or are located somewhere near the camera lens and are pointed in the same direction. These LEDs bathe the target area with infrared light (in this case a baby crib for example) but this light does not disturb the baby because the baby cannot see it.
Often times these baby monitor systems are wireless home security cameras and monitors. The signal is sent using by the camera using radio waves to the monitor. Since the monitor is not connected by any type of cable it can be conveniently moved from room to room to maintain surveillance of the baby.
Remember, wireless home security cameras and monitors are not restricted to use as baby monitors only. These cameras and monitors are great for many different types of applications where a wireless camera and monitor would by useful.
Wireless home security cameras can be purchased with almost any feature or additional option that is available for their “wired” counterparts. Some of these features include: cameras for outdoor use or indoor use; cameras that can record audio as well as video; cameras that have Pan-Tilt-Zoom or PTZ functions to increase their field of view; day/night vision cameras; several different camera types or shapes such as box, bullet, and dome cameras; and even cameras that can be networked using the internet (called Internet Protocol ready or IP ready cameras).
