Chapter 10: Camera setup 
80  TruVision NVR 11 User Manual 
There may be occasions when you want to control who can see a camera image on a 
local monitor, such as if there is a camera located in a changing room. The recorder 
lets you select which camera (or cameras) is not displayed on the local monitor unless 
the user is logged in and has permission to view the camera images. A restricted 
access camera is not displayed on screen when no user is logged in. Instead a person 
walking by sees a black screen. See Figure 25 below. 
Figure 25: Example of a restricted access camera image 
 
To set up a camera for a restricted access view: 
1.  From the menu toolbar, click Camera Setup > Restricted Access Camera. 
2.  Select which cameras you want to have restricted access and click Apply. 
3.  Click Exit to return to live view. 
VCA setup 
The configuration of each individual VCA (Video Content Analysis) event is done in the 
camera browser. Within the recorder you can link actions to a VCA alarm from IP 
cameras that support this feature. 
There are several types of VCA events to select, depending on the camera model. A 
series of linkage methods can be triggered if a VCA event is detected. See Table 12 
below. 
Note: VCA events trigger recordings; they are marked in the recorder and allow you to 
easily find the assisted video.

VCA event types  Description 
Face Detection  When this function is enabled, the camera can detect a moving 
object that is moving towards it, triggering a configurable response. 
The camera can only detect a face looking directly into the camera, 
not side views. This feature is best suited when the camera is in 
front of a door or is located in a narrow corridor.
