AXIS Introduces Q7401 Series Single-Channel IP Video Servers with H.264/M-JPEG and Audio.
AXIS Communications has launched the Q7401 single-channel IP video server with audio, which for the first time uses not only M-JPEG, but also the most cost-effective H.264 compression format.
Moreover, this video server simultaneously generates three video streams with a resolution of up to 4CIF at a frequency of 25 fps in both Motion JPEG and H.264.
Among the features of AXIS Q7401 are the presence of a channel for two-way audio transmission, special slots for SD/SDHC memory cards, and support for PoE technology.
In addition to this, the new IP video servers are equipped with a 64 MB video buffer, motion and sound detectors, and also support IP network control of PTZ cameras from many well-known manufacturers.
For convenient work with video and control of the device itself, you can use web browsers, AXIS Camera Station or Milestone XProtect software.
AXIS Q7401 is the first video server from AXIS to support the most cost-effective H.264 compression algorithm, which reduces the size of transmitted video files by 50% compared to MPEG-4 and by 80% compared to M-JPEG, without degrading the video image quality.
In addition, IP video servers simultaneously broadcast three video streams over an IP network in H.264 and M-JPEG formats with a resolution of 176×120 to 720×576 pixels at a constant frequency of 25 fps. For each stream, the video server allows you to individually configure the resolution, compression format, and frame rate.
To organize audio communication between the operator and the video surveillance object, IP video servers are equipped with a line output for connecting a speaker and a 3.5 mm jack for a microphone or other sound source.
AXIS Q7401 uses a half-duplex mode for transmitting audio signals over an IP channel, which allows you not only to listen to the sound in real time, but also to record it on a PC synchronously with the video stream.
An additional advantage of the Q7401 is the ability to choose the method of its power supply: locally via an adapter or via Power over Ethernet technology (according to the IEEE 802.3af standard).
In the latter case, IP video servers and analog cameras connected to them will be powered via free wires of the twisted pair, through which the video signal is transmitted.
This method allows you to minimize the costs of components and installation of the IP video surveillance system.
To protect the video server from power surges, you can use an injector (Midspan).
Like many IP video servers for video surveillance systems, AXIS Q7401 connects directly to a 10BaseT/100BaseTX network and is equipped with a web server for remote management.
The video server provides high-quality digital video from a connected analog camera thanks to the latest-generation proprietary AXIS ARTREC-3 processor.
The distinctive feature of the new product from previous IP models is not only the use of the H.264 compression format, but also the ability to record video fragments on SD/SDHC memory cards and a more capacious 64 MB video buffer for temporary storage of pre-alarm video.
Connection of PTZ camera telemetry receivers to the Q7401 is carried out through its RS-485 and RS-422 ports.
Moreover, IP video servers allow you to control PTZ functions of a large number of models of analog PTZ cameras, including those from American Dynamics, Bosch, Panasonic, Pelco, Philips, Samsung and Sony.
The AXIS 295 joystick or dedicated IP video surveillance software can be used to remotely control the pan, tilt and zoom of these cameras.
What's more, the AXIS video server allows you to adjust the brightness, contrast and saturation of the camera image before encoding it, and remove the interlacing effect using a special filter.
The Q7401's security features are based on a built-in motion detector, active notification technology and sound detection.
Like many IP video servers for security video surveillance, AXIS Q7401 has 4 inputs for connecting security sensors and 4 relay outputs to which external actuators can be connected.
For temporary storage of pre- and post-alarm frames, the new video server uses a capacious 64 MB video buffer.
The Q7401 responds to alarms by sending alarm video files to an FTP/HTTP server and/or sending event notifications to e-mail.
To protect video information from unauthorized access, IP video servers use a multi-level password system, IP address filtering, user access log, and HTTPS encryption.
The Q7401's smooth operation is ensured by the HTTP, FTP, SMTP, SNMP, NTP, RTSP, RTP, TCP, UDP, IGMP network protocols, and for integration into other applications, the video server supports an open API interface, including the AXIS VAPIX standard.
You can view video from the Q7401 and control the IP device from any network-connected computer with a standard web browser.
If your IP video surveillance system uses more than 3 IP video servers, we recommend using special software, such as AXIS Camera Station or XProtect Enterprise from Milestone.
These software applications allow you to view video from an IP video server in real time over an IP network, record video data to your computer's HDD, and quickly find and play recordings from your video archive.
The Swedish company AXIS Communications is the world's largest developer and manufacturer of network equipment and software for IP video surveillance systems.
AXIS supplies the world market with fixed network and wireless cameras, high-speed PTZ cameras, IP video servers, and software for creating multi-channel IP video systems based on local networks or the Internet.
Its offices operate in 18 countries worldwide and employ more than 500 people. More than 95% of AXIS products are sold outside Sweden.
