Many people put cameras in their homes for a variety of reasons. The most popular of these reasons is for the security of the home and the family within it.

Home cameras allow a family to view possible threats before becoming involved in the situation. A camera installed over the front door, for example, allows someone to see who is at the door when the bell rings without even having to be anywhere near the door.

Cameras are also used to watch over a particular area of the household or to keep an eye on a certain person to ensure his or her safety.

A camera placed in view of a swimming pool can keep swimmers safe or catch someone who causes damage to the area when the family isn’t around.

Cameras can be used to record all activity in the home or place of business with the purpose of preventing people from doing anything improper.

When people are aware that there’s a camera in a particular area, their behavior will change. This works even if the camera is a fake intended to simply deter individuals from committing acts that would get them in trouble were they recorded on tape.

Cameras can be found in many varieties, including wireless cameras as well as those that are connected directly to a computer. When choosing a camera, your choice should depend on the needs of you particular situation and your budget.

You should also consider the location of the computer on which your recordings will be stored as well as the type of things that you want to protect when choosing a security camera.

You have a lot of options, so do some research and don’t be afraid to ask questions if you’re not sure about what kind of camera would be best for you.

It is essential to know what resolution means after shopping for a surveillance camera. CCTV cameras have a resolution series from 330 TVL (television lines) to 600 TVL. For color resolution, CCTV cameras max out at 560 lines, however you can obtain black and white CCTV surveillance cameras in 600 TVL.

IP security cameras are only offered in much higher resolution, up to 5 megapixels. In the United States, automatic TV transmission (not high definition) displays 480 lines of resolution. Obviously the higher the resolution of the camera that you choose, the more detail you will see in your surveillance video.

High definition television (HDTV) displays either 1080 or 720 lines of resolution depending on the channel and the type of HDTV that you have. In order to obtain higher resolution from surveillance cameras, the now option is IP based megapixel cameras, which join over an IP network instead of a closed circuit.

Generally, IP mega-pixel cameras are much additional expensive than CCTV cameras. For high end applications that demand ultra-high resolution, megapixel cameras can denote surveillance video at additional than twice the resolution of high definition television.

About public that are shopping for a security camera are unrealistic (as of their lack of knowledge) about what a surveillance camera can describe (especially CCTV cameras). Certain community consider that if you obtain a 480 lines of resolution camera by a 3.6mm lens that you will be able to get a clear picture both of an object that is 20 feet away with an object that is 80 feet away.

Although the 3.6mm lens will certainly pick up the object in detail at 20 feet away, it cannot pick it up at 80 feet away too using the same 3.6mm lens. Digital zoom is potential by high end megapixel cameras, but not using common resolution CCTV cameras. Because of the huge price discrepancy between CCTV with IP mega-pixel cameras, a lot of times it makes sense to add more CCTV cameras instead of upgrading to megapixel cameras. This will lead us into the next article which will be particular understanding plus choosing the right camera lens.
