18x PoE Network Camera Features
1. What is a 18x PoE Network Camera?
The 18x PoE Network Camera is a stand-alone system connecting directly to an Ethernet or Fast Ethernet network. The
18x PoE Network Camera differs from a conventional PC Camera because it has an integrated system with built-in CPU
and web-based solutions, providing a low cost solution that can transmit high quality video images for monitoring. The
18x PoE Network Camera can be remotely managed, accessed and controlled using a web browser by any computer
over an Intranet or Internet.
2. What is the maximum number of users that can access DCS-3415 simultaneously?
The maximum number of users that can log onto the 18x PoE Network Camera at the same time is 10. Please keep in
mind the overall performance of the transmission speed will be reduced if many users have logged on to the camera
simultaneously.
There is no limit for the number of users when multicast-enabled router is being used. The multicast protocol helps reduce
network bandwidth consumption. Note that the Network Camera must be configured to enable multicast streaming. For
more information, see RTSP Streaming on page 41.
3. What algorithm is used to compress the digital image?
The 18x PoE Network Camera utilizes MPEG-4 simple profile or MJPEG Mode image compression technology providing
high quality images. MJPEG is a standard for image compression and it can be applied to various web browsers and
application software without installing any extra software
4. Can I capture still images from the 18x PoE Network Camera?
Yes, you can capture still images using the snapshot function.
