Depending on the type of camera or DVR kit you purchased, you may receive two different types of BNC "Bayonet Neill–Concelman" cables for the cameras. Our BNC or Coaxial cables are color coded based on the camera resolution it's used for. 

Purple - ULC Certified BNC cables for 4K cameras (e.g. PRO-4KMSB).
It can also be used on any cameras below 4K and Analog cameras with BNC connector.

Blue / Light Blue - for TVI and AHD cameras like the PRO-T855 and PRO-1080MSB or those that use pixels (e.g. 720p, 1080p) which determines their resolution (except SDI cameras).
It can also be used on any Analog cameras with BNC connector but not with 4K.
