27X Optical Zoom
The 27X optical zoom block offers an extensive zoom range from 5.56mm to 150.29mm starting at 60° all the way out to 3.2° horizontal angle-of-view for maintaining image crispness from ultra-wide to long telephoto shots.

IP (HEVC/SRT) Workflow
SRT stands for Secure Reliable Transport. SRT is an open-source video transport protocol and technology stack that optimizes video streaming performance across unpredictable networks. With secure streams and simplified firewall traversal, SRT delivers the best quality video over the worst networks.

Low-light Sensitivity
The CV420-27X operates with exceptional low-light sensitivity, ensuring a clear picture in variable and challenging lighting conditions, including live events, houses of worship, indoor or outdoor sporting events, and other dynamic lighting environments.

P (HEVC) Convenience
One cable to camera provides up to UHD video, audio, control, and power (PoE) over one cable with IP (HEVC) and HDMI simultaneous outputs with stereo audio embedding.

CV420-27X Applications:
The CV420-27X is suitable for use in networked HD and 4K (UHD) workflows where image quality and versatility are of utmost concern, including live broadcast productions, courtroom capture, corporate video, government assembly, sportscast, newscast, reality television, concerts, house of worship and many more.
