They can easily be relocated without having to rely on nearby power or communication sources. Lux units measure sensitivity, that is, the amount of light per square meter. Low lux units in the camera's specs means it has enhanced ability to operate in poor ambient light conditions. As a rule of thumb, the larger the size, the higher the quality of the image produced and the higher the price. Your decision should take into account the amount of light existing in the camera's environment.
Video from Security recorder could be displayed on a regular TV monitor. Darker environments require 1/3" - 1" sizes.
The basic CCTV system can be divided into three components: The plug and play cables are easy enough to install by non-experienced users. Will you monitor the house 24/7? Or will you simply record using a time lapse VCR and then view the tapes after something happens. WCCTV technology uses microwaves in the form of radar, radio, or lasers to transmit the camera signals to a remote location-a radio receiver, a DVR, your PC or laptop, or wherever else you'd like to view the images.

Black-and-white surveillance cameras are the most IR-sensitive; most color-cameras are equipped with filters that block out infrared light to enhance image quality. Many manufacturers have come out with IR-sensitive dual-mode cameras, which offer color images and can switch from daytime to night vision automatically, but the IR-sensitivity of these, too, varies according to the camera. So if you're investing in a CCTV system and want to incorporate IR illumination, make sure you check the cameras for IR-sensitivity in advance. based on intended implementation and requirements.
