There are several types of security cameras available in the market today. Several retailers like Ryalex offer cameras that fulfill multiple purposes. Some of them are as follows:
A single view
Before you set up this type of home security camera, ask yourself what you want your security camera to see. This will help you determine how many cameras you want to get, and where you want them positions.

If you decide to get just one camera, for example, you might install a place outside but is projected onto the front of your house, so you can see who is coming in the front door in an instant. This particular camera should have a broader view, and approximately 3.6 mm lens.
Coverage location of some
Home security cameras come with several different types of lenses. If you want a camera with a wide scope, a 3.6 mm lens is a good, basic lens to begin with. However, they will not give the details of a good face on someone who is more than about 25 feet away.
For that, you need a larger lens, either 6 mm or 8 mm, which will give you more detail from afar. You can also get more than one camera if you want both more detail and a wider area of coverage, simultaneously.
Every good security camera will provide good image quality during the day, but for the protection of the night, the infrared camera is a good choice. These cameras do "double duty," in that they take clear color images during the day, and then switch to black and white images with infrared illumination at night.
