compliant limited power source (LPS)
with either a rated output power
limited to ≤100 W or a rated output
current limited to ≤5 A.
Important
If a DC power supply is used
to power the product, the low
voltage power cord shall be
equipped with a ferrite core.
DC power input
SD Card Slot
Supports microSD cards with up to 64 GB of storage. For best recording performance, use a microSDHC or microSDXC card with
speed class 10.
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:
• 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 and bandwidth affected.
• Heavy usage of event settings affect the product’s CPU load. Frame rate affected.
• Using HTTPS may reduce frame rate, in particular if streaming Motion JPEG.
• Heavy network utilization due to poor infrastructure. Bandwidth affected.
• Viewing on poorly performing client computers lowers perceived performance. Frame rate affected.
• Running multiple AXIS Camera Application Platform (ACAP) applications simultaneously may affect performance.
• If the product includes several camera units, running applications on multiple cameras may affect the frame rate.
