Compare SD vs HD


The chart below shows the major differences and limitations fo both the SD (Standard Definition) and HD (High Definition) Cameras to assist in your selection.  If you are using your videos in post production processing the HD system would give you the best results because of the higher resolution.  Addtitionally the HD cameras can be controlled via the OSD (On Screen Display); Analog are factory configured for the best overall setting.  We have multiple VIDEOS on our website to aid you in your selection. 

Terminology -

SD - Standard Definition Cameras (Analog) with very good quality and resolution.  This type of camera connects to the AV or Composite connection on a TV or Monitor.  The connection on the TV is normally a YELLOW RCA Type connection. 

HD-SDI - [Serial Digital Interface] -With a frame rate of 60fps this is the highest quality camera with vivid colors and excellent picture quality.  SDI cameras are considered to be "broadcast quality" and are used in production of TV and other professional environments.  We are probably the only manufacture that offers this quality in a system that can be viewed at the surface. Recordings made with this camera are excellent in post production and cable lengths are limited to 150' to maintain quality.

HD-TVI & HD-AHD - [HD Quality] - With a frame rate of 30fps this is considered to be the next best competitor to our highest quality camera while still maintaining very good quality color and functionality while extending the cable length up to 1000'.
