Image

The default image settings can be configured under Video> Video Stream. Select the Image tab.

The following settings are available:

•Resolution. Select the default resolution.

•Compression. The compression level affects the image quality, bandwidth and file size of saved images; the lower the compression, the higher the image quality with higher bandwidth requirements and larger file sizes.

•Rotate image. If required, the image can be rotated.

•Maximum frame rate. To avoid bandwidth problems, the frame rate allowed to each viewer can be Limited to a fixed amount. Alternatively, the frame rate can be set as Unlimited, which means the Axis product always delivers the highest frame rate possible under the current conditions.

•Overlay settings. See Overlay, on page 23.

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 Axis product supports two H.264 profiles. The Main profile provides higher compression than the Baseline profile with the same video quality, but requires more processing power to decode.

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. 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, frame rate and image quality are affected negatively. To partly compensate for this, it is possible to prioritize either frame rate or image quality. Not setting a priority means that frame rate and image quality are equally affected. You must save your settings before they can take effect.

The current bit rate can be set to appear as text overlay. To do this, select the Include text check box option under Overlay Settings 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 38.

•When setting up continuous recording. See Continuous Recording, on page 43.

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

axis q6042s ptz dome network camera specifications

The Axis Q6042-S PTZ Dome Network Camera is a sophisticated device designed for high-performance surveillance in diverse environments. With its robust construction and advanced features, this camera is ideal for use in critical areas such as airports, train stations, and city surveillance, ensuring reliable monitoring and security.

One of the standout features of the Axis Q6042-S is its high-definition image quality. The camera offers a resolution of up to 720p, allowing for clear and detailed video capture. This is further enhanced by its powerful zoom capabilities, featuring a 36x optical zoom lens. This enables users to focus on distant objects without sacrificing image quality, making it easy to identify individuals or objects of interest.

The pan-tilt-zoom (PTZ) functionality of the Axis Q6042-S is another significant characteristic. The camera can pan 360 degrees continuously and tilt from -20 to 90 degrees. This extensive range of motion provides complete coverage of the surveillance area, allowing operators to track fast-moving objects efficiently. Additionally, with preset positions, users can quickly move to key areas of interest, streamlining the monitoring process.

For versatility in different lighting conditions, the camera includes features such as day/night functionality and Axis' Lightfinder technology, which enhances its ability to capture color images in low-light environments. The advanced image processing capabilities ensure that the video remains clear and detailed, regardless of the lighting conditions.

Another technological advantage of the Axis Q6042-S is its advanced compression technologies, including H.264 and Motion JPEG. These technologies allow for efficient video streaming, reducing bandwidth and storage requirements without compromising video quality. The camera also supports Power over Ethernet (PoE), simplifying installation by allowing both power and data to be delivered over a single cable.

Moreover, the Axis Q6042-S is equipped with built-in analytics capabilities, enabling it to detect motion and trigger alerts based on predefined parameters. This intelligent functionality not only enhances security but also reduces the need for constant monitoring, allowing operators to focus on critical events.

In summary, the Axis Q6042-S PTZ Dome Network Camera stands out with its high-definition imaging, extensive PTZ capabilities, low-light performance, advanced compression technologies, and built-in analytics. Its robust design and versatile features make it an excellent choice for any surveillance application requiring precision, reliability, and ease of use.
