Stream Profiles, Bit Rate Control | Axis Communications M3204-V

AXIS M32 Series

Bit Rate Control

The bit rate can be set as Variable Bit Rate (VBR) or Constant Bit Rate (CBR). VBR adjusts the bit rate according to the image complexity, using up bandwidth for increased activity in the image, and less for lower activity in the monitored area.

CBR allows you to set a fixed Target bit rate that consumes a predictable amount of bandwidth. As the bit rate would usually need to increase for increased image activity, but in this case cannot, the frame rate and image quality are affected negatively. To partly compensate for this, it is possible to prioritize either the frame rate or the image quality whenever the bit rate needs to be increased. Not setting a priority means the frame rate and image quality are equally affected.

Note:

To determine a reasonable bit rate, go to Setup > Video > Video Stream > Image, check the Include checkbox and enter the code #b in the Include text: field. The current bit rate is displayed as a text overlay on the Live View page.

To view the image stream while configuring the GOV settings and Bit rate control, select Open... under Preview.

MJPEG

Sometimes the image size is large due to low light or complex scenery. Adjusting the maximum frame size helps to control the bandwidth and storage used by the Motion JPEG video stream in these situations. Defining the frame size as Default provides consistently good image quality at the expense of increased bandwidth and storage usage during low light. Limiting the frame size optimizes bandwidth and storage usage, but may give poor image quality. To prevent increased bandwidth and storage usage, the maximum frame size should be set to an optimal value.

Stream Profiles

There are 4 pre-programmed stream profiles available for quick set-up. These settings can be adjusted and new customized profiles can be created. Each profile has a descriptive name, describing its usage and/or purpose. The profiles can be accessed from the Live View page.

•To add a new stream profile, click Add to bring up the Stream Profile Settings panel. Choose a descriptive name and enter a description for your profile.

Choose the form of Video encoding you wish to use from the drop-down list:

H.264 - Also known as MPEG-4 Part 10. This is the new generation compression standard for digital video. This function offers higher video resolution than Motion JPEG or MPEG-4 at the same bit rate and bandwidth, or the same quality video at a lower bit rate.

Motion JPEG - Delivers a high quality video stream, from which individual images can be extracted and saved.

•Copy an existing stream profile to your system and rename the copy

•Modify an existing stream profile based on the light situation and motion to be captured by your camera. See Stream Pro- file Settings for more information.

•Highlight the stream profile you wish to remove, then click Remove to remove it from the list.

M3204, M3203, M3203-V, M3204-V specifications

Axis Communications is renowned for its innovative approach to network video technology, and its M3200 series is a testament to this legacy, comprising models such as the M3204-V, M3203-V, M3203, and M3204. These cameras are designed to meet the diverse needs of surveillance applications while maintaining high standards of video quality and performance.

One of the standout features of the M3200 series is its compact and discreet design. The cameras are ideal for indoor use in environments where aesthetics are vital, such as retail stores, hotels, and offices. Their unobtrusive form factor allows them to blend seamlessly into various settings while providing comprehensive monitoring capabilities.

The M3204-V and M3204 models support two-way audio, allowing users to not only monitor but also communicate through the camera. This feature is particularly useful for interactive communication in scenarios like customer service or security personnel directions. Additionally, it supports an audio input for connecting external microphones, which enhances situational awareness.

All models in the series are equipped with Axis’ Lightfinder technology, enabling them to capture high-quality video in low-light conditions. This technology ensures that users receive clear and detailed images even in challenging lighting environments. Furthermore, the M3200 series offers Wide Dynamic Range (WDR) functionality, which helps to enhance the visibility of both dark and bright areas in a scene simultaneously.

With support for1080p resolution at up to 30 frames per second, the M3200 series delivers crisp and detailed video, making identification easier. The cameras also feature H.264 compression technology, which helps optimize bandwidth and storage requirements without sacrificing quality.

For added versatility, the M3200 series includes a wide variety of mounting options, making it easy to install the cameras in various settings. They also come equipped with an IP51 rating for dust and drip protection, ensuring reliable operation even in less-than-ideal conditions.

Moreover, the integration of Axis' Zipstream technology efficiently compresses video, thereby decreasing storage and bandwidth usage while retaining critical forensic details. This is particularly beneficial for long-term archiving of footage without quality loss.

In conclusion, Axis Communications M3200 series models such as the M3204-V, M3203-V, M3203, and M3204 offer advanced features tailored for effective surveillance. The combination of compact design, enhanced low-light capabilities, flexible installation options, and superior image quality positions the M3200 series as a top choice for those seeking reliable and efficient security solutions.
