Wireless Home Security Nightvision Cameras Are Your Eyes After Dark
It may come as a surprise to some people that home and business break-ins often occur after dark. While daytime burglaries do happen, the majority of intrusions occur after hours when lighting in and around the target building is minimal. The use of wireless home security nightvision cameras is becoming more popular to provide video evidence of burglaries to aid prosecution of the perpetrators as well as provide insurance companies proof that a crime actually occurred.
While most home and business owners prefer color images to better identify persons caught on video, some of the best wireless home security nightvision cameras offer color during the day but after dark switch to black and white image illuminated by infrared illuminators to be able to see in total darkness. This type of wireless home security nightvision cameras offers the opportunity to actually determine detail, as well as facial recognition in the images captured in the dark.
One of the key advantages of using wireless home security nightvision cameras is that they can be installed without the need to run power and cable lines from the camera to the recording device. Typically, with the newest equipment, the receiver is connected to a digital video recording device and all captured images are stored on a hard drive. Should an image be needed for court appearances, it can be transferred to a digital video disk without any additional loss of quality.
Automatic Apertures Only Provide Needed Light
Many of the wireless home security nightvision cameras are capable of color images during the day and switch to black and white night mode only after dark. Sensors in the camera determine if the lack of light is due to darkness or a cloudy sky. During periods of heavy clouds, the camera will remain in the color mode but at night will switch to black and white with infrared illumination to enable the camera to see in total darkness.
Batteries in many of the wireless home security nightvision cameras will last at least 30 days of normal use, however in night mode when the infrared light is in use, battery drain may be quicker. Most of the cameras can be connected to a power source that recharges the batteries as needed and others will have to replaced on a regular schedule. The use of rechargeable batteries can cut the cost of replacements.
As more home and business owners install security systems, the use of wireless home security nightvision cameras is becoming more popular to provide around the clock surveillance to meet their protection needs.
