IP video server Axis Q7406 blade .
Axis Communications has released the first 6-channel IP video server Axis Q7406 blade, which uses the highly efficient H.264 compression format and traditional M-JPEG.
The new product is made in the form of a board (blade), which must be installed in a special Axis rack. It converts the analog video signal from connected cameras to digital, with subsequent transmission of digital video streams over an IP network.
Up to 6 analog cameras can be connected to one Q7406, and the video is “digitized” for each channel using a separate ARTREC-3 processor of the latest generation with its own RAM and flash memory of 128 MB.
The use of the H.264 compression format in the Axis Q7406 allows the “weight” of the video image to be reduced by 80% compared to the Motion JPEG format and by 50% compared to MPEG-4 with the same video quality, which allows you to create more capacious video archives and reduce the requirements for the IP network bandwidth.
Therefore, using an IP video server with an economical H.264 compression algorithm, you can double the video archive with the same image resolution and frame rate without increasing the size of the disk array.
IP video servers are mounted in an Axis Q7900 4U rack, which is designed for 14 devices of this model and allows you to service IP video surveillance systems that combine up to 84 analog cameras.
In addition to the Axis Q7900, the new IP video server can be installed in the AXIS 291 1U rack, which can accommodate three Q7406 devices or other Axis blade models.
Axis IP video servers provide the ability to generate up to three individually configured video streams and transmit them simultaneously over a TCP/IP network. For each video stream, the Q7406 allows you to select any of the H.264 or M-JPEG compression formats and transmit video with a resolution of 176×120 to 720×576 pixels at a speed of 25 fps.
In addition, before encoding the video, the user can adjust the brightness, saturation and contrast of the image, and, if necessary, rotate it by 90°, 180° or 270°, overlay titles or a protective mask on the image.
Moreover, the new IP video server has a special filter for removing the «comb» at the edges of the image of moving objects, which usually comes from analog cameras with a CCD matrix with interlaced scanning.
The ability to control 25 models of analog PTZ cameras from American Dynamics, Bosch, Panasonic, Pelco, Philips, Samsung, Sony allows integrating Axis IP video servers into existing video surveillance systems. Connection of analog PTZ camera telemetry receivers to the Q7406 is carried out via its RS-485 interface. For remote control of pan, tilt and zoom of cameras, the video server supports the Axis 295 joystick with 12 programmable buttons and a USB interface. In addition, using specialized software, you can set the patrol mode and the sequence of control of PTZ functions of cameras.
Thanks to the open API architecture, the new IP video server can be integrated into various software applications. Quick installation and reliable operation of Q7406 in an IP network is ensured by support for various network protocols: HTTP, FTP, SMTP, SNMP, UPnP, NTP, RTSP, TCP, UDP, RTP, IGMP, etc. At the same time, the video servers support a password system, IP address filtering, and encryption via the HTTPS protocol to protect video information from unauthorized access.
When creating multi-channel IP video surveillance systems based on Axis Q7406, it is recommended to use specialized software, such as Axis Camera Management or Axis Camera Station. With this software, you can access all IP video servers from any network PC and manage video from Q7406, including viewing video streams in real time, recording them to your computer's hard drive, and finding and playing archived video files.
The built-in motion detector, which Q7406 IP video servers are equipped with, records all changes in the field of view of video surveillance cameras.
Via the Q7406 alarm inputs and outputs for each channel, you can connect external security sensors and control the operation of lighting or sound (light) alarms.
When an alarm signal is received from a sensor or detector, the IP video server can automatically activate video recording of the alarm event on a remote computer, record all alarm frames to its 64 MB video buffer, and send alarm video to pre-specified e-mail addresses.
