as a suggestion why not pull in another cat 6 and feed the forth camera off this ? If its only a 20mtr run in tube it shouldn't be too bad to install (Just watch the new burning against the existing cable if you do it )

Analog CCTV systems have been in use for many years and their popularity among many homeowners and business people is impeccable. Analog systems are widely preferred because they transmit the video signal obtained in form of electrical signals.

Analog CCTV cameras use coaxial cables, especially the Siamese cable for the wiring. Their videos are recorded via a DVR, which is a Digital Video Recorder where every single camera in a building is connected to the DVR.
