HDMI Extenders and Splitters for CCTV Monitors

An HDMI extender carries a picture to a monitor further away than a standard HDMI lead can manage. Most here send the signal over Cat5e or Cat6 cable using a transmitter and receiver pair, in Full HD and 4K versions with different maximum distances, and some add USB for a keyboard and mouse. There are also splitters that feed one source to two or four screens. Check the distance and resolution before you buy.
