However, the total amount of energy produced by the tungsten lamp over the entire spectrum is comparable to that of the other lamps. Figure 3-8 shows the human eye response and spectral sensitivity of standard CCTV camera sensors. 2 Tungsten-Halogen Lamps The discovery of the tungsten-halogen cycle significantly increased the operating life of the tungsten lamp. Tungsten-halogen lamps, like conventional incandescent lamps, use a tungsten filament in a gas-filled light-transmitting envelope and emit light with a spectral distribution similar to that of a tungsten lamp.
The only improve ment to be made, assuming that the camera has good resolu tion, is to choose a monitor having resolution equal to or better than the camera or transmission link bandwidth. Chap ter 7 gives more detailed characteristics of monochrome and color monitors used in the security industry. 1 Monochrome By far the most popular monitor used in CCTV systems is the monochrome monitor, which comes in sizes ranging from viewfinder size, which has a 1-inch-diagonal CRT, up to a large display monitor, which has a 27-inch-diagonal (or larger) CRT.
Lamps come in two types: tungsten or tungsten-halogen lamps, which have solid filaments, and gaseous or arc lamps, which contain low- or high-pressure gas in an enclosed envelope. Arc lamps can be further classified into HID, low-pressure, and high-pressure short-arc types. HID lamps are used most extensively because of their high efficacy and long life. Low-pressure arc lamps include fluorescent and low-pressure sodium types, which are used 48 CCTV Surveillance in many indoor and outdoor installations.
