outputs are rated at 500 mA. They are provided in both the normally open (N/O) and normally
closed (N/C) configuration on the rear panel of the unit, and are isolated.
The two relays can be activated by activity detection, by active alarms, video loss or by Macro
functions. There are four choices on relay output for ACTIVITY on each camera:
q
None – no relay is activated
q
Relay 1
q
Relay 2
q
Relay 1&2.
The factory default setting for Alarm Output Relays is as follows:
q
q
All Alarm Inputs will activate
Relay 1
q
q
All Activity Detection will activate Relay 2
q

All Video Loss will activate
None
INTRUSION PARAMETERS SETUP
NOTE:
Settings of INTRUSION parameters are very important for correct detection by the system.
Read the following section carefully.
The menu for INTRUSION PARAMETERS SETUP appears as:
Intrusion Parameters Setup
Camera : 01
Sensitivity : 05
Rejection : LOW
Target Size : 001
Link to Alarm : 01
[CANCEL] [OK]
Sensitivity:
Refer to instructions above for ACTIVITY.
Recommendations:
When choosing sensitivity, choose the highest setting that does not result in very frequent ‘false’
motion detections, while the FALSE ALARM REJECTION setting is on ‘LOW’, and the TARGET
SIZE is set correctly. (See below). The higher the sensitivity, the more likely it is that incidental
movement will be detected as motion, so if motion is indicated without apparent cause, reduce the
sensitivity. Do no use sensitivity level 10 with INTRUSION, and use level 9 carefully.
When setting high sensitivity, such as 8, 9 or 10, it is very important to ensure that sources of false
motion, such as trees and bushes which may move in the wind, or windows which can reflect
flashes of light, are eliminated from detection if possible. To do this, DISABLE the corresponding
zones as described above in SETUP ACTIVE ZONES. Only after the sensitivity is set to its
reasonable maximum should the programmer adjust the False Alarm Rejection as needed.
Rejection (False Alarm):
(This setup is only
used for INTRUSION detection.) Motion detection and false alarms will vary
from scene to scene, but processing to reduce false alarms can often result in reduced motion
