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 H.264 stream settings can be configured from the Video > Video Stream page. Select the H.264 tab. The settings defined in this page will apply to all H.264 streams that do not use a stream profile.

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 Axis product supports the following H.264 profiles:

•Baseline. The Baseline profile is recommended for clients that don’t support CABAC entropy coding.

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 dynamic 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 dynamic. 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 31.

•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.

Q1932E specifications

Axis Communications, a leading provider of network video solutions, offers a range of advanced surveillance cameras designed to meet the needs of various security applications. Among their innovative products is the Axis Q1932E, a robust thermal network camera that excels in challenging environments where visibility is compromised.

The Q1932E is particularly valued for its ability to detect and monitor objects and people in complete darkness, smoke, fog, or adverse weather conditions. This capability stems from its thermal imaging technology, which detects heat emitted by objects rather than relying on visible light. As a result, users can achieve reliable surveillance across different lighting conditions, making it ideal for critical applications like perimeter security, transportation, and infrastructure monitoring.

One of the main features of the Axis Q1932E is its resolution. The camera offers a thermal resolution of 384x288 pixels, allowing for detailed thermal imaging. This resolution is crucial for identifying potential threats even from a distance. The built-in digital Pan-Tilt-Zoom (dPTZ) capability allows users to zoom in on specific areas of interest, enhancing monitoring efficiency without losing sight of the broader scene.

Durability is another key characteristic of the Q1932E. It is designed with a weatherproof casing, complying with the IP66 standard, ensuring it can withstand harsh weather conditions such as rain, wind, and fluctuating temperatures. This rugged design makes it suitable for outdoor installations in various environments.

The camera also features Axis' advanced video analytics capabilities, enabling motion detection and edge analytics. These functionalities allow users to receive real-time alerts and notifications when unusual activity is detected, enhancing response times to potential security threats. The integration of Axis’ Zipstream technology further optimizes bandwidth and storage usage, reducing costs while maintaining high-quality video streams.

Installation is made convenient with Power over Ethernet (PoE) support, which allows both data and power to be delivered through a single cable, simplifying the setup process. Additionally, the camera supports various mounting options, providing flexibility to adapt to different surveillance needs.

In summary, the Axis Q1932E thermal network camera is a powerful tool for security professionals seeking to enhance their surveillance capabilities. With its superior thermal imaging, durability, advanced analytics, and ease of installation, it is an excellent choice for ensuring safety and security in any environment, regardless of the lighting conditions.
