The primary advantage offered by the CCTV Security Cameras is that it will keep a watchful eye round the clock, 24*7 a day. When buying CCTV camera, it is essential to pay special attention to the digital surveillance system. The CCTV system consists of the camera and its lens, a CCD i.e. Charge Couple Device sensor and a monitor.
For that, the cameras will need to be paired with an infrared (IR) unit. As IR requires no light (it ”sees” on a different light wavelength spectrum), it isn’t rated in terms of LUX, because that measure is reserved for measurement of visible light intensity. Any good security camera system is composed of several components but the cameras are the most crucial element because they’re the ”eyes” of the system.
When it comes to a security camera and its LUX, it’s always better to go with one that that has as low a number as possible when it’s important that a camera be able to pick up movement or activity in very dim conditions. For example a camera that’s rated at 1 LUX will usually have no problem “seeing” during the early evening hours or just before dusk.
