Home Security Cameras Info

Home security cameras with “night vision” or infrared (IR) capabilities are becoming increasingly popular. Crimes often occur in the dark, where thieves and vandals can operate more easily and freely. It’s important that you and your family feel protected when pulling into your dimly lit driveway or entering your darkened garage.

There are several choices when deciding on a home security camera with night vision for your home security surveillance needs. Take the time to explore the many options prior to purchasing.

Certain home security cameras capture color images in the daytime and black and white cameras during the night.

Just like regular home security cameras, night vision home security cameras send security video footage to a VCR or PC, where they play on a monitor and are recorded to either a tape or a targeted hard drive.

How do Night Vision Security Cameras Work?

In order to understand night vision home security security cameras, you’ll need to know the various types that exist and how they work:

Infrared or night vision home security cameras have LEDs (light emitting diodes) in the front that automatically turns on when the level of light drops off. These LEDs produce an infrared light not visible to the human eye but seen by your night vision security camera.

Yes, infrared light is considerably more limited than light visible to the human eye. But it still allows black and white images to be captured, even in pitch black, which can help with any criminal investigation.

Some home security video cameras with night vision possess “image enhancement” which is a technology that grabs limited amounts of light that exist at night. Again, this light is so limited that is impossible for the human eye to detect it. The resulting image on your home security video monitor usually appears greenish.

Other night vision home security cameras utilize “thermal imaging.” This technology uses the emanating heat emitted from objects. Any living object emits a certain amount of heat, whether it’s a person or an animal or a plant. Objects such as trees emit less heat than human bodies, for example.

When deciding on home security video surveillance with night vision, take the time to survey your property and decide on the appropriate location. Home security companies are often more than happy to service you and help with your decision. Once your home is monitored, your sense of security will instantly increase. You don’t have to be “in the dark” as far as your home security needs anymore!
