Camera without moving parts in a dome-shaped housing.
Flash Memory
See CF Card.
fps
Abbreviation for frames per second. See Frame Rate.
Frame rate
The frame rate specifies how many frames per second (fps) are generated and sent by the
camera. The human eye perceives movement as a fluid video sequence when more than
12 image per second are produced.
HDTV
Abbreviation for High Definition TV.
HiRes
Abbreviation for High Resolution. Refers to high-resolution images (above 1megapixel).
Image compression
Image compression reduces the file size of an image. This is particularly important when
transferring and saving files.
Image processing
Digital image processing. The goal is to correct errors made during image generation (caused
by overexposure, underexposure, blurring, weak contrast, image noise, etc.) in order to
create a “better” image.
IP Network
Data network based on the Internet protocol (TCP/IP).
IP Telephone
See VoIP.
JPEG
Abbreviation for Joint Photographic Experts Group. Responsible for the development of the
JPEG standard method for image compression. JPEG is the most common lossy image format
for photos on the Internet. Loss in image quality is barely noticeable at compression rates
lying between 60 and 99 percent.
Latency
Time interval elapsed between the time an image is captured by a camera and when that
same image is displayed on the monitor.
