Recently, this technology has been incorporated into the CCTV industry. According to Dvrunlimited research, The megapixel CCTV cameras advertised by 90% of installers in the USA are IP based computer network cameras, although these cameras give great reproduction, they are limited by the bandwidth, specification of your network equipment and may slow down other users on the network. Another major problem with IP cameras over a network is lagging (not real-time) and frame Judder, when the network catches up.
