One of the best methods for being able to maintain your home’s security and safety involve the use of an outdoor security camera. It may be enough to deter a crime from happening in your home just by having a security system in place. There is not thief that wants to be caught on video tape during the middle of the crime, so they will choose to avoid any place that is going to be able to record their actions. They will tend to flock toward a home that is not protected and they can easily get in and out of the home without having to worry about being detected. Outdoor wireless security cameras will provide you with the most inexpensive way to be able to protect your home against any potential crime or vandalism from occurring.

Like any other Digital Video Reorder (DVR), a 16 channel digital video recorder uses a computer hard drive to compress and store video images using various compression techniques. (Incidentally, “16 channel” means the DVR can work with up to 16 cameras simultaneously.)
The compression techniques include JPEG, MPEG, Wavelet and a host of proprietary methods. Images can be stored at a rate of just a few frames per second (fps) to as many as 400fps depending on the software features offered by the manufacturer. This is the latest in CCTV DVR Video Surveillance technology, eliminating the use of tape recorders.
What exactly is a 640 x 480 infrared camera? This can be a complicated answer for many reasons. In the following article we will attempt to address some of the characteristics that can make this seemingly simple question so complicated. Specifically, we will briefly discuss infrared technology and the reference to display resolution and how they relate to a 640 x 480 infrared camera.
First lets discuss the meaning of “infrared” when we talk about a 640 x 480 infrared camera. The term “infrared” refers to the wavelength of electromagnetic radiation. The wavelength of infrared radiation generally ranges between 0.7 and 300 micrometers abbreviated as “µm.” The exact range and categories defined may vary slightly depending on the scale that is used to describe the radiation.
