Glossary of Terms
Active X: Active X is Microsoft software component technology which facilitates sharing of information between
differing applications. Video recorders (NVRs and HVRs) utilize Active X to remotely view security cameras online.
Compression: Compression Techniques are used in Digital CCTV to reduce the file sizes of recorded video
images. Typical compression formats used for video are: MJPEG, MPEG-4, H.264 & H.265.
PAL (Phase Alternate Line): This is the Video encoding standard for Europe.
NTSC (National Television Systems Committee): A committee that worked with the FCC in formulating
standards for the present day United States color television system and is their video encoding standard.
Iris: This parameter enables the user to set the degree to which the aperture opens or closes to maintain proper
light levels on the security camera sensor. Works similar to the iris on the human eye to adjust for light.
Zoom: To enlarge or reduce, on a continuously variable basis, the size of a televised image primarily by varying
lens focal length.
Resolution: The number of horizontal lines a system can display.
Digital Resolution (e.g. 720 x 576)
720 = number of points in each row that make up the picture
576 = number of rows
Frame Rate: The quality of a Digital Surveillance Systems is often determined by the Total Frame Rate it can
record at. The higher the Frame Rate, the higher the quality of recording and the more Real Time your CCTV
recording will be - Real Time recording for 1 camera is 25 Frames Per Second (PAL).
Motion Detection: Recording method for digital surveillance systems. When someone walks in front of a camera,
the pixels change and the SATATYA device defines this as motion. The surveillance system will then record these
images to the hard disk. This is a popular recording setup as every event recorded is actually motion driven as
opposed to a static image if the system was set to record 'round-the-clock'.
Sensitivity: The sensitivity of a camera is configured on the digital surveillance system. Motion Detection based
recording uses relies on the sensitivity of the cameras to trigger recording.
Hue: Corresponds to colors such as red, blue, etcetera.
