LOCKING A CAMERA

You can prevent other users or scripts from controlling an ASCII camera by locking the camera. When a camera is locked, only the user or script

that placed the lock can control the camera. If you attempt to control a locked camera, VMX300(-E) will display a message specifying that the

camera is locked and who placed the lock. To lock and control a particular camera, you must belong to, and log in under, a user group that allows

you to lock and control that camera.

Every VMX300(-E) user and script has a priority assigned by the system administrator. VMX300(-E) uses these priorities to resolve situations in

which two or more users or scripts attempt to control a particular device at the same time. The user with the higher priority is given control of the

device.

Depending on your priority, you might be able to take the lock from another user or a script that has locked a camera, giving you control of the

camera. You can take the lock from any user with lower priority than you. You can take the lock from any script with equal or lower priority.

VMX300(-E) automatically unlocks a camera you have locked under the following circumstances:

•If you log off, either by closing the client, or by logging in a new user.

•If you locked the camera from the Control tab of the Device Control dialog box and you close the dialog box.

•If you locked the camera from the gadget in a custom window and you change the content type for that window.

•If you locked the camera from the gadget in a custom window and you clear Visible for that window in the Workspace Properties dialog

box.

Locking has no effect on auxiliaries. Scripts and other users can still control auxiliaries when the camera is locked, regardless of their priority.
