The CV-2000 was developed by Sony engineer Nobutoshi Kihara. It used 1⁄2-inch-wide (13 mm) video tape in a reel-to-reel format, meaning the tape had to be manually threaded around the helical scan video head drum. The CV-2000 was one-tenth the weight and price of other analog video recording products of its era.[5] It recorded television programs in black and white using the skip field process, which produced a maximum 200-lines resolution. 

en models were developed in the CV series: CV-2000, TCV-2010, TCV-2020, CV-2100, TCV-2110, TCV-2120, CV-2200, DV-2400, CV-2600 and CV-5100.[2] Sony also sold an optional 'Video Camera Ensemble', known as the VCK-2000. This add-on kit contained a separate video camera, a microphone, and a tripod.[6]

One of its shortcomings as a format was the omission of the ability to adjust tracking, which made interchangeability of tapes between different machines almost impossible. Sony's later AV series machines included this feature.[8] The CV video recorders fell into disuse with the arrival of the EIAJ type 1 standard that was used by many companies, including Sony with their AV series machines.

This video recorder is from before the development of multichannel rotary air-gap transformers, which were commonly used for the spinning heads of VHS recorders, to pass analog video signals across the gap from the spinning upper half to the stationary lower half of the head assembly. This recorder instead uses an earlier slip-ring and brush contact system for the spinning heads, with two sets of brushes to increase signal reliability. However it can still experience video signal quality problems if the metal of the brushes or rings become oxidized / corroded, or coated with dust.
