10-6. BW

This function lets you switch from colour to black-and- white picture automatically in low light conditions such as at night.

1.Move the cursor to BW.

2.Select AUTO1, AUTO2, EXT, ON or OFF using [Left] or [Right].

The factory default setting is OFF.

AUTO1: The camera selects black and white mode if the picture is dark, or colour mode if the picture is bright enough.

AUTO2: Applying AUTO1 may cause malfunction when using a source of near-infrared light at night because the illuminance changes signifi- cantly when switching between the colour pic- ture and a black-and-white picture. This can be prevented by using the AUTO2 setting to detect the type of light source.

Notes:

Because the type of light source is detected based on information received from the CCD image pickup element, an object that is con- stantly moving or has the same colour as its background may not always be properly recog- nized. When choosing the AUTO2 mode, make sure to use a light source having a wavelength of 800 nm or more.

The object may be out of focus when using a source of near-infrared light than using the visi- ble light.

EXT: Colour picture reverts to black-and-white pic- ture when an external day/night switching signal is received (refer to alarm connections).

ON: Black-and-white mode enabled.

OFF: Colour mode enabled.

3.Select AUTO1 or AUTO2 using [Left] or [Right].

4.Press [SET].

The AUTO1 or AUTO2 menu appears on the monitor screen.

5.Move the "I" cursor to LEVEL to select the illumi- nance level using [Left] or [Right].

The factory default setting is HIGH.

LOW: Colour picture switches to black-and-white picture at approx.2 lx.

HIGH: Colour picture switches to black-and-white picture at approx.5 lx.
