This chapter provides information and instructions for managing the Cisco Video Surveillance PTZ IP camera, and includes the following topics:
•Understanding the PTZ IP Camera User Interface
•Powering the PTZ IP Camera On or Off
After you log in to the PTZ IP camera, you can access the windows and perform a variety of administrative and user procedures.
The links and activities that you can see and access in the PTZ IP camera windows depend on your camera privilege level.
•Administrator—Can access all PTZ IP camera windows, features, and functions.
•Viewer—Can access the Camera Video & Control window with limited controls, and can access the Refresh, Logout, About, and Help links from that window.
The PTZ IP camera user interface includes links that you use to access various windows and perform other activities. Table 4-1 describes each link and lists the PTZ IP camera privilege level that you must have to access the link.
The PTZ IP camera user interface includes these main windows:
•Home window—Displays the system information that is described in Table 4-2.

•Camera Video & Control window—Displays live video from the camera and lets you control a variety of camera and display functions.
The PTZ IP camera does not include an on/off switch. You power it on or off by connecting it to or disconnecting it from a power source. When you power off the PTZ IP camera, configuration settings are retained.
To power on the PTZ IP camera, take either of these actions:
•Use an STP (shielded twisted pair) Category 5 or higher network cable to connect the PTZ IP camera to a network switch that provides 802.3af compliant PoE.
•Use an optional AC 24V power adapter to connect the PTZ IP camera to a wall outlet.
To power off the PTZ IP camera, take either of these actions:
•If the PTZ IP camera is receiving PoE, disconnect the network cable.
•If the PTZ IP camera is receiving power through the power adapter, unplug the adapter from the wall or disconnect it from the camera.
You reset the PTZ IP camera by pressing the Reset button on the PTZ IP Camera (see Figure 1-1). There are various reset types, as described in Table 4-3.
You also can also perform these reset operations from the Maintenance Settings window as described in the Cisco Video Surveillance PTZ IP Camera Configuration Guide.

Enable Motion Detection check box |
Enables the motion detection feature and displays a grid over the video image. When motion detection is enabled, the PTZ IP camera monitors activity in regions of the video that you specify. If activity at a defined level occurs in any of these areas, the PTZ IP camera generates an alert and takes the actions that are configured as described in the "Event Notification Window" section on page 4-9. After motion detection has been enabled, you create specific regions that the PTZ IP camera monitors for activity. To create a motion detection region, right-click on the video image, choose Draw Region, and then click and drag across the motion detection grid to draw a green square or rectangle comprised of one or more grid squares. Up to eight of the following regions can be drawn: •Motion inclusion regions—Designate areas to examine for motion. You can draw up to four motion inclusion regions. •Motion Exclusion Regions—Designate areas to ignore for motion. You can draw up to four motion exclusion regions. For each region listed under the Region Properties area, you can configure the following properties: •IsActive—Specifies whether the region is active (enabled) or not active (disabled). Chose true to enable a region; choose False to disable a region. •Location—Specifies the grid coordinate (X, Y) for the upper left corner of the region. •Name—You can enter a name of up to 12 characters for a region. •Region Type—Specifies whether the region is an inclusion or an exclusion region. Choose Inclusion to have the region examine for motion; choose Exclusion to have the region ignore motion. •Sensitivity—Designates the relative amount of activity that the PTZ IP camera must detect in the area before it generates an alert. A lower value means that more, or faster, activity is required to trigger an alert. A higher value means that less, or slower, activity is required. The default value is 80. •Threshold—Designates the percentage of pixels that the PTZ IP camera must identify as changed in the area before it generates an alert. The camera detects pixel changes at the defined sensitivity level. The default threshold value is 10. To reset the sensitivity and threshold to their default values of 80 and 10 respectively, right-click on the region, and choose Restore Values. To remove a region, right-click it, and choose Delete Region. |
