the control center computer fails, MOBOTIX cameras are still capable of placing
alarm phone calls autonomously, for example.
If the Time Tables are engaged for activating and deactivating the camera's event
control (or parts thereof) according to opening hours and vacation times, for exam-
ple, the resulting video surveillance system is easily adapted to the requirements of
the installation.
Internal Sensors: Complete, Yet Expandable
Besides the image sensors and the integrated video motion detection, MOBOTIX
cameras feature other physical sensors (PIR sensor, microphone, internal tempera-
ture, etc.), which can trigger events. The camera's
logical
sensors round off the pic-
ture as they can be used for further detection tasks: Hence, the camera can send
an e-mail with an attached live image for testing purposes if the illumination falls
below a certain level or it may call you if an event recording has been completed.
The integrated signal input lines further extend these capabilities as these inputs
can be used to integrate external sensors (light barriers, external PIR sensors,
switches, etc.).
Actions and Messages: Reacting Flexibly to Events
If the MOBOTIX camera detects an event, it can execute actions and send mes-
sages. In order to react differently when detecting different events, you can set sev-
eral message paths for the camera, for instance. This could mean that the PIR sen-
sor switches on the lamps using the signal output, while the alert message via
email or phone call is only sent if the video motion windows detect movements
within the illuminated scene.
Actions and messages can also be controlled using Time Tables; this allows adjust-
ing the action and messaging features to the application tasks at hand.
Event Logic and Event Counter: Filtering Events
The event counter is an event filter that prevents the camera from immediately
executing an action or sending a message; it will only do so if a certain number of
the selected events occur within the specified timeframe.
The event logic allows combining actions and messages and will only execute
alarm actions or send messages if two events occur in a specific order. For
instance, when using two different video motion windows, these would only trigger
an event if a person would walk through the detection windows from right to left
but not vice versa. Combining these features with the signal inputs and external
sensors will cover nearly any kind of application scenario.
