Exposure Compensation - Lorex LZV1722 Instruction Manual

1 Using the On-Screen Display (OSD) Menu
To configure the camera's exposure mode:
1. Use the on-screen arrow keys to navigate to CAMERA SETTING and click Enter.
2. Select EXPOSURE SETTING and click Enter.
3. Under AE MODE, click the left / right arrow keys to select one of the following exposure
modes:
• AUTO: The settings for gain, iris, and shutter are determined automatically by the
software.
• IRIS PRIORITY: Configure iris settings only. Gain and shutter settings are deter-
mined automatically by the software.
• SHUTTER PRIORITY: Configure shutter settings only. Gain and iris settings are de-
termined automatically by the software.
• MANUAL: Advanced users only — this mode requires you to configure the settings
for gain, iris, and shutter to achieve proper exposure.
4. Under GAIN SETTING, click the left / right arrow keys to set the gain value (1–16). Set-
ting the gain manually allows you to artificially create a brighter (high gain) or darker
(low gain) image. The AE MODE must be set to MANUAL to configure the gain value.
5. Under SHUTTER, click the left / right arrow keys to set the shutter speed (1/4 – 1/
30,000). Setting the shutter speed manually determines how long the camera shutter
remains open when capturing an image. It is recommended to keep shutter speed set
to 1/60 to ensure smooth video. The AE MODE must be set to MANUAL or SHUTTER
PRIO to configure the shutter speed.
6. Under IRIS, click the left / right arrow keys to adjust the iris (1–18). Setting the iris man-
ually determines how much light comes through the lens. The AE MODE must be set
to MANUAL or IRIS PRIO to configure the iris setting.
