AXIS 214 PTZ 11

Video and Audio Streams

The AXIS 214 PTZ provides several different image and video formats. The type to use depends on your requirements and on the properties of your network.

The Live View page in the AXIS 214 PTZ provides access to Motion JPEG and MPEG-4 video streams, as well as to single JPEG images. Other applications and clients can also access these video and audio streams/images directly, without going via the Live View page.

Video Stream Types

Motion JPEG

This format uses standard JPEG still images in the video stream. These images are then displayed and updated at a rate sufficient to create a stream that shows constantly updated motion.

The Motion JPEG stream uses considerable amounts of bandwidth, but also provides excellent image quality and access to each and every individual image contained in the stream.

Note also that multiple clients accessing Motion JPEG streams can use different image settings.

MPEG-4

This is a video compression standard that makes good use of bandwidth, and which can provide high-quality video streams at less than 1 Mbit/s.

The MPEG-4 standard provides scope for a large range of different coding tools for use by various applications in different situations, and the AXIS 214 PTZ provides certain subsets of these tools. These are represented as Video object types, which are selected for use with different viewing clients. The supported video object types are:

•Simple - sets the coding type to H.263, as used by e.g. QuickTime™

•Advanced Simple - sets the coding type to MPEG-4 Part 2, as used by AMC (AXIS Media Control)

When using MPEG-4 it is also possible to control the bit rate, which in turn allows the amount of bandwidth usage to be controlled. CBR (constant bit rate) is used to achieve a specific bit rate by varying the quality of the MPEG-4 stream. When using VBR (variable bit rate), the quality of the video stream is kept as constant as possible, at the cost of a varying bit rate.

Notes:

•MPEG-4 is licensed technology. The AXIS 214 PTZ includes one viewing client license. Installing additional unlicensed copies of the viewing client is prohibited. To purchase additional licenses, contact your Axis reseller.

•All clients viewing the MPEG-4 stream must use the same image settings.

Audio Stream Types

The audio stream types for audio are:

•G.711 - International standard for encoding wired-telephone audio. Uses PCM samples to compress audio where higher signal values are compressed more than lower values. In Axis products, this sets the coding type to μ-law 64 kbit/s.

•G.726 - Uses PCM samples to code the difference between samples (ADPCM). Reduces bandwidth without losing too much useful audio. In Axis products, this sets the coded bit rate to 24 or 32 kbit/s.

All stream types are ITU-T standards and operate on frequencies of up to 4 kHz.

214 PTZ specifications

The Axis Communications 214 PTZ is a sophisticated network camera designed for surveillance and security applications. This camera is equipped with advanced features that allow for flexible monitoring and exceptional image quality, making it a preferred choice for various environments including retail, transportation, and public spaces.

One of the standout features of the Axis 214 PTZ is its Pan-Tilt-Zoom capabilities. The camera can pan 360 degrees continuously and has a tilt range of 90 degrees, providing users with the ability to cover large areas. With its powerful zoom function, the camera can magnify subjects up to 36 times, making it easier to identify details from a distance. This is particularly useful for applications requiring detailed observation, such as monitoring entrances or tracking vehicles in a parking lot.

The 214 PTZ also boasts impressive image quality, supporting up to 4CIF resolution at full frame rate. It employs progressive scan technology and delivers clear images, even in challenging lighting conditions. This is further enhanced by features such as day/night functionality, which allows the camera to switch to infrared mode for low-light environments. The built-in wide dynamic range (WDR) capability helps to balance scenes with high contrast lighting, ensuring that both bright and dark areas are visible.

In terms of connectivity, the Axis 214 PTZ utilizes Power over Ethernet (PoE), simplifying installation and reducing cable clutter by allowing the camera to receive power and data through a single Ethernet cable. This enhances flexibility in camera placement as it eliminates the need for separate power supplies. Additionally, the camera supports various video compression formats, including H.264 and Motion JPEG, optimizing bandwidth usage while maintaining high-quality video streams.

Security is paramount in surveillance applications, and the Axis 214 PTZ is equipped with robust security features. It supports HTTPS encryption, ensuring that video feeds are secure from unauthorized access. The camera also includes tampering alarms and a secure access control system that can restrict user access based on specific permissions.

Lastly, the user-friendly interface and compatibility with various Axis Video Management Software solutions allow for seamless integration into existing security systems. The camera's robust construction ensures reliability in diverse weather conditions, making it an ideal choice for both indoor and outdoor applications. Overall, the Axis Communications 214 PTZ camera combines advanced surveillance technology with user-centric design to deliver a versatile and dependable security solution.
