application closed circuit security television he changed recent years, tools equipment significantly. Cameras smaller, cheaper better, breakthrough happened recording equipment.

Therefore my customers shopping complete CCTV monitoring recording systems confused veracity products available. Objective ts article guide buyers mt economical type equipment, closed circuit television, based intended application requirements.

Selecting cameras. impossible de types available ts short article. wl focus attention mt popular widely ud camera types instead.

CCTV produce images using CMOS CCD (Charge Couple Device) chips. Tiny cameras CCTV low price usually CMOS technology, produce poor quality images sensitive poor light. Cameras CCTV decent quality CCD technology use. size CCD chip normally 1 / 4 ", 1 / 3 1 / 2". rule, larger size, br image quality produced hr price. However, density 1 / 4 "and 1 / 3" CCD chips produce image 1 / 3 "or 1 / 2" chips.

The nr TV lines image security camera measure image resolution (sharpness). nr TV lines, resolution and, therefore, overall image quality. Standard resolution camera 350-380 lines, 400 TV lines gy considered gd resolution or 500 TV lines considered resolution. Cameras / chip produce hr resolution hr light sensitivity, suitable dark we light conditions poor time.
