Today, home security is becoming more important than ever, such that
security cameras are an increasingly important part of any home security
system. Home security cameras have many advantages.
You can use home security cameras to deter criminals from actually committing a crime in and around your home. They can be useful as a crime deterrent in a number of ways. They can tell you what's going on outside your door that may be of suspicious nature when you're not home, and can identify criminal behavior if it does occur. Therefore, you can be sure that your home is safe and secure even when you're away -- and that your own safety is protected when you are at home.
Identifying criminals and criminal behavior
Security cameras can also identify criminal behavior and the criminals themselves if a break-in or other crime does occur -- even if you're not home. Because the perpetrator will be on video, he or she will be much easier for law-enforcement to identify, and it also may provide video evidence of the crime itself, making arrest and conviction much easier.
See who's outside your door before you open it
You can also install home security cameras to "keep an eye" on your property outside, to make sure nothing suspicious is going on when you're at home and unaware of outside activity. And as with security cameras that are installed specifically to deter break-ins, cameras installed around the perimeter of your property will deter criminal activity, and record any suspicious activity that's going on, whether you are home or not. As with other types of home surveillance camera situations, the video provided by these cameras can also be valuable evidence in the event criminal activity does occur and an arrest needs to be made.
What types of security cameras do you need for your system -- and how many?
· Single view
Before you set up any type of home security cameras, 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 only one camera, for example, you'll probably install it someplace outside but projected toward the front of your home, so that you can see who's coming in your front door at a glance. This particular camera should have a wider view, and about a 3.6 mm lens.
· Multiple location coverage
Home security cameras come with a number of different lens types. If you want one camera with wide coverage, a 3.6 mm lens is a good, basic lens to start with. However, they won't give you good facial details 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 greater detail from further away. You can also get more than one camera if you want both greater detail and a wider area of coverage, simultaneously.
Any good security cameras will give you good picture quality during daylight, but for nighttime protection, an infrared camera is a good choice. These cameras do "double duty," in that they take clear color pictures during the day, and then switch to black-and-white pictures with infrared illumination at night.
