The phrase PTZ Camera has two uses within the video security and
surveillance products industries.
First, PTZ is an acronym for pan, tilt, and zoom and may refer merely
to features of specific surveillance cameras. Second, PTZ Cameras may
also be used to describe an entire category of cameras where a
combination of sound and/or motion and/or change in heat signature may
enable the camera to activate, focus and track suspected changes in the
video field.
By activating only during times of change, systems can notify human
monitors and minimize storage requirements.
In the March 2009 edition of "Security Products" magazine, Keith
Jentoft notes the continuing problems organizations have with outdoor
PTZ cameras during thunderstorms. Despite continuing improvements in PTZ
software, problems with continual activation during thunderstorms have
led some organizations to completely disable these types of cameras
during the duration of thunderstorms. This translates to continuing
challenges in trying to monitor and protect facilities from crime and
terrorism during inclement weather. [edit] Auto tracking
A new innovation to the PTZ camera is a built-in firmware program
that monitors the change of pixels generated by the video chip in the
camera. When the pixels change due to movement within the cameras field
of view, the camera can actually focus on the pixel variation and move
the camera in an attempt to center the pixel fluctuation on the video
chip. This process results in the camera following movement. The program
allows the camera to estimate the size of the object which is moving and
distance of the movement from the camera. With this estimate the camera
can adjust the cameras optical lens in and out in an attempt to
stabilize the size of pixel fluctuation as a percentage of total viewing
area. Once the movement exits the cameras field of view the camera
automatically returns to a pre-programmed or "parked" position until it
senses pixel variation and the process starts over again.
This process is remarkably reliable and proven to enhance the overall
effectiveness of PTZ cameras.
