R
Region of Interest
The defining of a specific area within a field of view to be used by the motion detection algorithm to only look for motion within this region.
Resolution
The measure of the fine detail that can be seen in an image. For analog systems this is typically measured in Television Lines or TVL. The higher the TVL rating, the higher the resolution.
RS232/485
A communication interface for third party control and firmware upgrades to the AutoDome products.
Rule
AutoDome’s alarm management subsystem that uses “if this, do that” rules to perform specific actions when an event occurs.
S
Sector Blanking

SensUp
Increases camera sensitivity by increasing the integration time on the CCD. This is accomplished by integrating the signal from a number of consecutive video frames to reduce signal noise.
Singlemode Fiber
An optical fiber with a silica (e.g. glass) core with a diameter of less than 10 microns. Used for
Spot Focus
Activates Auto Focus for three seconds after camera movement.
Subnet Mask
Subnetting is a method that allows one large network to be broken down into several smaller ones. Depending on the network class (A, B, or C), some number of IP address bits are reserved for the network address (subnet) and some for the host address. For example, Class A addresses use 8 bits for the subnet address and 24 bits for the host portion of the address. Class A subnet masks are denoted 255.0.0.0. Class B addresses (16 bits for both the subnet and host address) use a 255.255.0.0 subnet mask. Class C addresses (8 bits for the subnet and 24 bits for the host address) use a subnet mask of 255.255.255.0.
