AXIS M1143–L
Technical Specifications
Digital Input 3Connect to GND to activate, or leave floating (unconnected)
to deactivate.
0to+40VDC
Digital Output 4Internal connection to ground when activated, floating
(unconnected) when deactivated. If used with an inductive
load, e.g. a relay, a diode must be connected in parallel with
the load, for protection against voltage transients.
Max load =100 mA
Max voltage = +40 V DC
3.3 V max 50 mA

Performance Considerations
When settings 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:
• High image resolution and/or lower compression levels result in images containing more data. Bandwidth affected.
• Access by large numbers of Motion JPEG and/or unicast H.264 clients. Bandwidth affected.
• Simultaneous viewing of different streams (resolution, compression) by different clients. Effect on frame rate and bandwidth.
• Accessing Motion JPEG and H.264 video streams simultaneously. Frame rate a nd bandwidth affected.
• Heavy usage of event settings affect the product’s CPU load. Frame rate affected.
• Heavy network utilization due to poor infrastructure. Bandwidth affe cted.
• Viewing on poorly performing client computers lowers perceived performance. Frame rate affected.
