Which security cameras are right for your system depends on your individual needs and budget; are you placing them indoors or outdoors? Is 1080P a large enough resolution? Will they be able to see and record video efficiently in low-lighting? Are they placed with adequate field of view, or will a PTZ (Pan Tilt Zoom) camera be necessary? These are all important questions to be considered when choosing security cameras for your CCTV camera installation project.
