AXIS 2110 User’s Manual Choosing Your Application 27Image frequency for Networking ApplicationsWhen used in a TCP/IP networking environment, the AXIS 2110 delivers up to 15images/second; where the actual image frequency is typically limited by:• your browser/computer• the image size• the lighting conditions at the point of installation.• the available network bandwidth• complexity of detail and color variation within the imageImage Compression RatiosThe file size of a JPEG-compressed image depends upon the actual content of the image.Images containing a lot of detail will generate larger files. Image quality is controlled bythe level of compression; high compression yields small files, while low compressionmaintains higher image quality at the expense of larger files. The table below containsaverage file sizes in kilobytes, derived from real-life tests:Note: Using a modern computer will avoid introducing any unnecessary bottleneck when view-ing the images.Lighting ConditionsJust like any camera, the shutter time of the AXIS2110 increases in low light conditions to guaranteeoptimal image quality.The actual frame rate for your images is affected bythe prevailing light conditions in your applicationenvironment. Although the AXIS 2110 will producegood quality images right down to 3 Lux, locallighting should ideally be stable at 40 Lux or more toachieve optimal image frequency. Consequently, youcan expect a reduced frame rate under low lightconditions in your application environment, as shownin the diagram (right).Typical File Sizes (kbytes)ResolutionAt lowestcompressionAt lowcompressionAt mediumcompressionAt highcompression640 x 480 250 kb 20 kb 13 kb 8 kb320 x 240 70 kb 8 kb 5 kb 3 kbImages / sec.Lux2153 40More light = better frame rate
