1 Product brief
The AXIS 211A is a professional-level network camera from the market leader in
network video. Enhancing the visual communication by adding two-way audio
capabilities to the functionality of the AXIS 211A, it is suitable for surveillance and
remote monitoring applications.
The AXIS 211A offers communication via microphones and speakers along with the
live images over the local area network or across the Internet - no need for dedicated
cable installations. It is an ideal choice for applications in the fields of e.g. education,
transportation, government, retail and healthcare where two-way audio is required.
Connecting directly to IP networks, the built-in Web server, open application interface
and sophisticated networking functions, such as the option to power the camera over the
Ethernet, greatly simplify installation and systems integration.
The summarized key features are:
• DC-Iris lens: featuring a varifocal DC-Iris, which automatically
regulates the amount of light entering the camera. Zoom and focus are
adjusted manually with the aid of the pullers mounted on the lens.
• Power over Ethernet (PoE): supporting network transformers
conforming to IEEE 802.3af, the AXIS 211A can be powered directly
from the network cabling.
•
Two-Way Audio: enhances communication by providing two-way audio
capability. Audio communication can be bidirectional (full duplex), push
to talk (half duplex) or in one direction only (simplex). The AXIS 211A
has an integrated microphone, but there is also an audio input for
connecting an external microphone source producing a line level signal.
An active speaker with a built-in amplifier can be connected to the audio
output to enable two-way communication.
• Progressive Scan CCD: renders moving objects without blur. More
information can be found at:
• Up to 30 frames per second in VGA 640 x 480 resolution
• Simultaneous Motion JPEG and MPEG-4 streams optimize for
quality and bandwidth
• Built-in video motion detection reduces network load and storage needs
by uploading video only when change is detected.
• Pre- and post-alarm image buffering: 9 MB (approx. 5 min. of
320x240 resolution video at 4 frames per second)
• Powerful Application Programming Interface (API), which facilitates
developers in building applications that support Axis products
• Axis Superior Im
