Depending on your needs you can find the camera that is right for you. If you need to identify faces, you’ll need a vastly different security camera from a need to simply monitor crowd traffic patterns. If the area you want to monitor is outdoors, there are requirements such as durability concerns that need to be address unlike an indoor security camera. Your budget and size of your security system, the number of cameras you require, will also affect your final decision.  An additional consideration for outside security cameras is the light source. All cameras require adequate light to properly photograph a subject and video cameras are no exception. This ability to use light is measured as a lux rating. The lower the lux rating of a camera, the less light it needs to deliver a useable image. If you intend to mount your camera in a spot with little or no available light you have to get the lowest lux rated camera you can find that will allow you to see the person in front of the camera. An infrared outdoor security camera is often the clear choice for reliable outdoor surveillance. These cameras capture a high-quality color video in day light and at night-time switches to a black and white with its infrared night vision mode. In low light conditions these infrared cameras can detect movement within 10 to 100 feet depending on the models capabilities. The budget cameras are at the lower end of the scale while the Hi-Res top-of-the-line cameras can offer exceptional night-time vision. If you ever wondered why you’re children are always bruised when left with the nanny, now you can watch your kids get beaten to a pulp while you’re sitting at a cubicle twiddling your thumb. To start, determine if you want a wireless or a wired camera. This is actually an obvious choice for some because wireless just sounds so much cooler. Remember that a wireless security camera still might need to be plugged into the wall socket if that is the cameras power source.

                    In industrial plants, CCTV equipment may be used to observe parts of a process from a central control room; when, for example, the environment is not suitable for humans. CCTV systems may operate continuously or only as required to monitor a particular event. A more advanced form of CCTV, utilizing Digital Video Recorders (DVRs), provides recording for possibly many years, with a variety of quality and performance options and extra features (such as motion-detection and email alerts). The first CCTV cameras used in public spaces were crude, conspicuous, low definition black and white systems without the ability to zoom or pan. Modern CCTV cameras use small high definition colour cameras that can not only focus to resolve minute detail, but by linking the control of the cameras to a computer, objects can be tracked semi-automatically.
