Metering Zone

The Metering Zone adjustment forces the IP camera to use the

brightness level in a specific area of an image to determine the

appropriate exposure. Exposure, defined as the amount of light

the sensor gets, will determine the brightness of captured

video.

If images are too dark, try adjusting the Metering Zone, which

has two settings: Normal, for most lighting conditions, and

Backlight, for when objects are illuminated from the back. For

each, the following settings are available:

• Safe Area (Averaging): Measures the light evenly from

all areas in the frame and sets the exposure to suit the

average light value.

• Center Spot (Center Weighted): The meter will use a concentrated region around the center of

the focused image. This type of metering technique works well for close-ups of buildings and

people, but poorly for landscapes and in the vicinity of the light source.

• Custom (Spot): If not used properly, this setting can result in the metered area being well

exposed while the rest of the frame is either underexposed or overexposed. For example, if

the main subject fills only a relatively small portion of a frame and/or reflects significantly

more or less light than the surrounding area — a black cat on a bright white sheet, for

instance — the average exposure for the whole frame may not be ideal.

The Custom Metering Zone is defined as a set of four coordinates (in pixels, always an even number)

representing a rectangle and using the following format:

Coordinate Description Range (in pixels)

X The x coordinate of the upper right corner 0–704

Y The y coordinate of the upper right corner 0–524

W The width of the rectangle 16–720

H The height of the rectangle 16–540

determine the appropriate exposure.
