AXIS 2411:
Questions & Answers

Q: What is a video server?

A: A video server is a unit, which allows connection of conventional analog CCTV products onto an Ethernet network. It will act as a gateway/converter between analog video systems and network systems. Viewing, and with some versions of video servers also control of, connected cameras can be done from anywhere on the network or even via Internet using a standard web browser or software application. Some applications will also provide storage of video for later review, alarm management and other additional features.


Q: When should I use the AXIS 2411 Video Server?

A: The AXIS 2411 is the perfect choice when you need to stream one channel of analog video over an IP network, without the need for any additional functions, such as alarm/event management or dome/PTZ control. The unit’s small casing requires minimal installation space, and it is a very cost effective solution for larger installations, whereby a low cost per channel can be achieved.


Q: Does AXIS 2411 Video Server support Power-over-Ethernet?

A: No, the AXIS 2411 does not contain built-in support for Power-over-Ethernet.


Q: Does AXIS Video Server support Wireless LAN’s?

A: Yes. AXIS 2411 Video Server works fine over wireless networks based on 802.11a,b or g standards. But it will require an external device point connected to it.


Q: What are the benefits of M-JPEG versus MPEG-4?

A: M-JPEG is the compression of choice for video surveillance as it prioritizes image quality over frame rate, has low latency (delay between actual activity and the presented video) and shows graceful degradation at bandwidth constraints and packet loss. The usage of M-JPEG guarantees a defined level of picture quality, which is vital in most security applications. As M-JPEG is also a less complicated compression, the number of available third party applications available is much higher. In contrast, MPEG-4 is more suited for applications where full frame rate and synchronized sound are more important than image quality, latency and resilience.


Q: What is the difference between AXIS 2411 and AXIS 2401+?

A: Both have the same video functionality, but the AXIS 2401+ also have support for serial devices such as modems, PTZ cameras and AXIS 2191 Audio Module. The AXIS 2401+ also contain alarm input / control outputs, event management, pre/post alarm buffers for video and support for scripts.


Q: Does AXIS 2411 support audio?

A: No, to benefit from audio, you would have to use AXIS 2400+ or 2401+ in conjunction with the AXIS 2191 Audio Module.


Q: Can I use dome cameras or conventional Pan/Tilt/Zoom cameras with my AXIS 2411?

A: No. The unit’s main focus is to provide high quality video. Therefore, it does not contain any serial ports which are required to control the dome or PTZ camera.


Q: Do I need any software? 

A: Although Axis video products are compatible with a wide range of professional software applications, such as AXIS Camera Recorder, you do not need any custom software in order to access the web-based configuration pages or view the images.

The Axis Video Servers uses the TCP/IP suite of protocols. All transportation of data is done through HTTP (the format used on the Internet) or FTP. Axis video products generate JPEG images, which are native to standard web browsers such as: Netscape Navigator 4.x. and MS Internet Explorer version 4.x or higher
