If you are planning to protect your home or business, it can be difficult to choose the right camera for you as there are massive collections of CCTV surveillance cameras offered by manufactures.
CCTV Cameras have become much more affordable and improved these days. With the growing needs of surveillance from security point it is very important to install the right quality camera that will ensure 100% security of your business with improving the efficiency of business.
Here are a few suggestions without getting too much technical, as you would have to write a book if looking for full explanation. Of course by the time it’s written, it will become out dated as technology in the CCTV industry changes rapidly. For these reasons, it is sensible to ask an expert to help design and install your system.
Why you need a surveillance camera? – Detection, Recognition or Identification. Detecting a person walking across a parking lot may be done with a wide angle camera. Recognition of a person vandalizing a car might require a closer zoom, higher resolution camera or additional camera. Identification, especially facial recognition, becomes a little trickier. In most applications you will need a specific camera aimed at a known area or a person, in order to capture a face shot. For most places this would be an entry door or sidewalk path.
Night vision is a must as many crimes occur under the cover of darkness. Two main technologies are used to capture a picture: IR (infrared) or Sense-Up (starlight technology). IR technology uses infrared illuminators (little red lights surrounding the camera lens) to produce a black and white picture in darkness. Sense-up technology uses the shutter speed of the camera to produce a color picture in very low light settings. If you have a very dark area at night with tree canopies or an unlit pathway, you would need to use an IR camera.
Placement and vandalism should be considered before choosing a camera. It is best to select a camera that gives you a video clarity for recognition and identification. For this reason, you must use a vandal resistant dome or turret camera that cannot be easily vandalized.
