9.4 Alarms

9.4.1 Activity Detection

Activity detection zones may be set for each camera.

Use the UP and DOWN keys to highlight different rows.

If you select the top (text) row, the sensitivity and pixel count can be set.

The sensitivity affects all selected pixels (zones). The higher this setting, the more sensitive

the activity detection is.

• Use the NUMBER keys 1-4 to set sensitivity (Sen)

The pixel count specifies the number of zones that have to be simultaneously active in order

to trigger an activity alarm (i.e. the higher the pixel count, the lower the chance of triggering)

• Use the NUMBER keys 5-9 to set the number of pixels (Pix)

As you select the various rows over the image, the NUMBER keys turn the zones across

the line on and off. If a zone is turned on, it will be sensitive to changes in the image.

The DEF key may be used to toggle all zones one or off.

Following an activity or alarm contact event, the relay is operated and held for a

programmable number of seconds.

9.4.3 Video Loss Alert

Set the cameras here that you wish to monitor for video loss (i.e. camera failure). The

simplest method is to press the DEF key. This will automatically check all the currently

connected cameras.
