H.264

H.264, also known as MPEG-4 Part 10/AVC, is a video compression standard that provides high quality video streams at low bit rates. An H.264 video stream consists of different types of frames such as I-frames and P-frames. An I-frame is a complete image whereas P-frames only contain the differences from previous frames.

The GOV length is the number of frames between two consecutive I-frames. Increasing the GOV length may save considerably on bandwidth requirements in some cases, but may also have an adverse affect on image quality.

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 more bandwidth for increased activity in the image, and less for lower image activity. When the activity in the scene increases, the bit rate would usually increase as well. If there is a surplus in bandwidth, this may not be an issue and selecting Variable bit rate (VBR) will be sufficient. But if bandwidth is limited, it is recommended to control the bit rate by selecting Constant bit rate (CBR). When the activity in the scene increases, VBR adjusts the bit rate according to the complexity, using up more bandwidth for increased activity in the scene, and less for lower scene activity. CBR allows you to set a target bit rate that limits the bandwidth consumption.

The CBR target bit rate works like the ceiling of a tent. It limits the bit rate, while maintaining some flexibility . The bit rate may bounce up and down within the set target but when it nears the set target value, the limitation kicks in. However, because CBR will always prioritize a continuous video stream, it allows temporary overshoots from the target bit rate. Because setting a target value prevents the bit rate from increasing, frame rate and image quality are affected negatively. To partly compensate for this, select which variable shall be prioritized, frame rate or image quality. Not setting a priority means that frame rate and image quality are equally affected.

The current bit rate can be set to appear as text overlay. Under Overlay Settings, select Include text and enter the modifier #b in the field.

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. Setting the frame size to the Default setting provides consistently good image quality at the expense of increased bandwidth and storage usage in 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

A stream profile is a set of predefined stream settings including resolution, compression, frame rate and overlay settings. Stream profiles can be used:

•When setting up recording using action rules. See Events on page 30.

•When setting up continuous recording. See Continuous Recording on page 34.

•In the Live View page – select the stream profile from the Stream profile drop-down list.

For quick setup, use one of the predefined stream profiles. Each predefined profile has a descriptive name, indicating its purpose. If required, the predefined stream profiles can be modified and new customized stream profiles can be created.

To create a new profile or modify an existing profile, go to Setup > Video > Stream Profiles.

To select a default stream profile for the Live View page, go to Setup > Live View Config .

Camera Settings

The Video > Camera Settings page provides access to advanced image settings for the Axis product.

M3204 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.
