AXIS P1425-E Network Camera
Technical specifications
•
Digital output
– For connecting external devices such as relays and LEDs. Connected devices can be activated by the
VAPIX® Application Programming Interface, output buttons on the Live View page or by an Action Rule. The output will
show as active (shown under
System Options > Ports & Devices
) if the alarm device is activated.
•
Digital input
– For connecting devices that can toggle between an open and closed circuit, for example: PIRs, door/window
contacts, glass break detectors, etc. When a signal is received the state changes and the input becomes active (shown
under
System Options > Ports & Devices
).

Performance Considerations
When setting up your system, it is important to consider how various settings and situations will affect performance. Some factors
affect the amount of bandwidth (the bit rate) required, others can affect the frame rate, and some affect both. If the load on the
CPU reaches its maximum, this will also affect the frame rate.
The following factors are among the most important to consider:
