Detecting video tampering

Video tampering, such as moving a camera to a different position, can also be detected

and set to trigger an action on the recorder.

Only IP cameras can be selected. However, not all IP cameras may support this

feature.

Note: It is strongly recommended not to configure for video tampering when using PTZ

dome cameras.

To set up video tampering detection:

1. From the menu toolbar, click Camera Management > Tamper-proof.

2. Select a camera to configure for tamper-proof.

3. Check the Enable Tamper-proof box to enable the feature.

4. Define a tampering area.

The tamper detection area setup interface lets you define an area on screen where

you want camera tampering to be detected. Click and drag the mouse across an

area to mark that area for video tampering. You can only set one tampering area

with the full screen being the maximum area. Click Clear to clear the screen.

5. Select the tamper detection sensitivity level by clicking the sensitivity scroll bar.

Higher sensitivity is to the right of the bar.

6. Select the arming schedules for the tamper.

Click Rule and then select the Arming Schedule tab to select the day of the week

and the time periods during the day when tamper can be detected. You can

schedule up to eight time periods in a day. Default is 24 hours.

Click Apply to save the settings. Click Copy to copy the settings to other days of

the week and holiday period.

Note: The time periods defined cannot overlap.

7. Select the response method to an external alarm.

Click Rule and then select the Rule tab to select the method by which you want the

recorder to notify you of the alarm. Click Apply to save settings and then OK to

return to the previous screen.
