Wireless PTZ Network Camera Features
1. What is a Wireless PTZ Network Camera ?
The Wireless PTZ Network Camera is a stand-alone system connecting directly to an Ethernet or Fast Ethernet network. The Wireless
PTZ 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 Wireless PTZ Network Camera can
be remotely managed, accessed and controlled using a web browser from any computer over an Intranet or Internet.
2. What is the maximum number of users that can access DCS-5220 simultaneously?
The maximum number of users that can log onto the Wireless PTZ 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 on the number of users when a multicast-enabled router is being used. The multicast protocol helps reduce the network
bandwidth consumption.
Note that the Network Camera must be congured to enable multicast streaming. For more information, see RTSP Streaming on page
41.
3. What algorithm is used to compress the digital image?
The Wireless PTZ Network Camera utilizes MPEG-4 simple prole 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 Wireless PTZ Network Camera?
Yes, you can capture still images using the snapshot function.
