Understanding the Lock Button
The Lock button is used to lock and unlock the camera, and also provides information on whether the camera is currently locked, whether you can
take the lock, and whether you can control the camera. The Lock button is located in the ASCII camera gadget and on the Control tab of the
camera’s Device Control dialog box.
Figure 78. Lock Button Locations
The color of the padlock in the Lock button indicates whether you can control the camera. When the padlock is green, you can control the camera.
When the padlock is yellow or red, you cannot control the camera. To control a particular camera, you must belong to, and log in under, a user
group that allows you to control that camera. If you do not have permission to control the camera, the padlock will always be red or yellow.
The state of the Lock button indicates whether or not you can lock the camera. When the button is out, the camera either isn’t locked, or it is
locked, but you can take the lock from the user or script that placed the lock. When the Lock button is in, the camera is locked and you cannot take
the lock from the user or script that placed the lock. To lock a particular camera, you must belong to, and log in under, a user group that allows you
to lock that camera. If you don’t have permission to lock the camera, the Lock button will always be in.
Permissions override priority. No matter how high your priority, you will never be able to lock or control a camera unless you have the necessary
permissions.
If you have permission to lock and control a camera and a user with lower priority than you has the camera locked, your Lock buttons are red/out,
indicating that you cannot control the camera, but you can take the lock from the other user and subsequently control the camera.
When another user with the same or higher priority than you has the camera locked, your Lock buttons are red/in, indicating that you cannot
control the camera and you cannot take the lock from the other user.
When a script with equal or lower priority than you has the camera locked, your Lock buttons are yellow/out, indicating that you cannot control
the camera, but you can take the lock from the script and subsequently control the camera.
When a script with higher priority than you has the camera locked, your Lock buttons are yellow/in, indicating that you cannot control the camera
and you cannot take the lock from the script.
If you have the Control tab and the camera gadget open at the same time, you see two different instances of the Lock button. These two Lock
buttons are independent of each other:
•If you locked the camera from the gadget, the Lock button on the Control tab is red/in, indicating that you cannot take the lock or control the
camera from the Control tab. The Lock button on the gadget is green/in, indicating that you have locked the camera and can control it using
keyboard controls or by clicking a custom window.
•If you locked the camera from the Control tab, the Lock button in the gadget is red/in, indicating that you cannot take the lock through the
gadget or control the camera using keyboard controls or by clicking a custom window. The Lock button on the Control tab is green/in,
indicating that you have locked the camera and can control it through the Control tab.
When you do not have the lock, the different instances of the Lock button are always in the same state.
