General: Includes camera orientation and digital processing settings. The orientation settings allow for 
standard or inverted installation of the camera. The digital processing settings adjust the sharpness, 
saturation, and contrast of the scene.

Exposure: Adjusts scene detail and contrast. A scene with correct exposure settings has adequate detail 
and contrast between white and dark values. An image with too little or too much exposure eliminates 
detail in the scene. The camera features auto and manual exposure settings.

Focus: Includes auto back focus and manual focus settings (refer to Focus in the IX Series Installation/
Operation manual [C2950M] or the IXE Series Installation/Operation manual [C2953M] for detailed 
instructions). If the camera is programmed to automatically back focus, the camera will routinely refocus 
when changes in the scene are detected. The camera will also run a quick autofocus sequence every three 
hours to adjust the center focal point of the scene. This quick autofocus sequence compensates for 
environmental temperature change and maintains optimal focus. If the auto back focus is turned off, the 
autofocus mechanism locks the camera at a user-specified position. The camera will not focus if changes 
in the scene occur. Manual focus is recommended only for indoor applications that have a single, 
unchanging primary light source.

Tone Map: Balances the brightest and darkest sections of an image to produce a picture with more 
balanced lighting and more detail.

White Balance: Defines how the camera processes video images to render true colors in a scene. White 
balance is especially effective in scenes with changing lighting conditions or in scenes with more than one 
type of light source.

Select Preset: Selects preset camera configurations, which include primary and secondary video stream 
settings available for easy setup.

Custom Configuration: Configures custom video stream settings. The camera features dual video 
streams with programmable settings for compression, resolution, and image rate. The default names for 
the streams are Primary and Secondary. Although each stream can be programmed independently, the 
settings of one stream can limit the options available for the other stream depending on the bandwidth 
consumed.

Users: Defines the permissions assigned to individuals logged on to the camera. Use this feature to 
create, modify, or delete user accounts.

Groups: Defines the permissions assigned to users within a group. Use this setting to create, modify, and 
delete groups and permissions. Multiple permissions can be assigned to each group.

General Settings: Changes the way the camera manages the users and groups settings. These settings 
can be managed on a camera-to-camera basis or by using a centralized server to apply changes to multiple 
cameras.

Sources: Defines the camera functions that are automatically triggered by an event source. The camera 
supports alarm, system, and timer event sources.

Handlers: Defines the actions that a camera takes when an event occurs. The camera supports four event 
handlers: Send Email, Write JPEG to SD Card, Upload JPEG to FTP Server, and Open/Close Relay.
