Pelco IS150 SW1-1:Video Format, SW1-2 Line Sync, SW1-3 Interlaced Scanning/Progressive Scanning

SWITCH SETTINGS

Locate the DIP switch. Then set the switches for your installation.

SW1-1: Video Format

Set to ON for NTSC. Set to OFF for PAL. The default is ON.

SW1-2: Line Sync

When multiple cameras are connected to the same switching device, vertical roll may occur on the monitor. AC line lock eliminates vertical roll by locking the frame rate to the power supply frequency. Each camera output is synchronized to the power supply frequency. (Refer to Vertical Phase Adjustment on page 10 for more information.)

Internal line sync disables line lock and synchronizes cameras internally.

Set to ON to use AC line lock. Set to OFF to use internal line sync. The default is ON.

SW1-3: Interlaced Scanning/Progressive Scanning

Interlaced scanning is the standard for analog recording installations. Each frame contains one odd and one even field, each processed separately.

Progressive scanning is better for digital recording installations. Each frame is processed as a whole, which results in less blurring and cleaner digital conversion. It also saves storage space on digital video recorders.

Set to ON to select interlaced scanning. Set to OFF to select progressive scanning. The default is ON.

SW1-4: AWB (Auto White Balance)/MWB (Manual White Balance)

Auto white balance is enabled by default (ON).

To manually set and lock the white balance:

1.Set SW1-4 to ON.

2.Hold a white background in front of the lens until the video shows all white.

3.While holding the background in place, set SW1-4 to OFF. A green block and a white block alternate briefly on the video image until the manual white balance process is complete.

SW1-5: Fluorescent/General

Enable this option to adjust the camera for best operation under fluorescent lighting.

Set to OFF for fluorescent lighting. Set to ON for general lighting. The default is ON.

NOTE: If you use fluorescent operation, you should use AC line lock for best results.

SW1-6: General WDR/Maximum WDR

Maximum WDR supports about 36 dB of additional dynamic range over a standard camera. Use it for installations that require the maximum WDR.

General WDR supports about 20 dB of additional dynamic range over a standard camera. Use it for installations that do not require the maximum WDR.

Set to ON to select maximum WDR. Set to OFF to select general WDR. The default is ON.
