AXIS Q7401 Video Encoder

Video and Audio

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.

To apply the settings, click Save.

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 36.

•When setting up continuous recording. See Continuous Recording on page 41.

•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 & Audio > Stream Profiles.

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

Camera Settings

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

Image Appearance

Increasing the Color level increases the color saturation. The value 100 gives maximum color saturation. The value 0 gives a black and white image.

The image Brightness can be adjusted in the range 0–100, where a higher value produces a brighter image.

The Contrast changes the relative difference between light and dark. It can be adjusted using the slidebar.

Video input

•Enter a descriptive name for your video source in the Video source name field.

•The values in the Offset Adjustments fields affect the horizontal and vertical synchronization for the image. This can be used to eliminate any black border surrounding the image. High values, both negative and positive can put the image out of sync.

•De-interlacing - is used to improve video stream image quality from analog devices. Select any of the following options from the De-interlacingdrop-down list. Select None if de-interlacing is not necessary; Blending for improved image quality that is not as processor intensive; Adaptive Interpolation performs de-interlacing of the video stream by applying different filters on the image. This may give a better result than Motion Adaptive Interpolation in rare cases; Motion Adaptive Interpolation performs de-interlacing of the video stream by applying different filters depending on the motion in different parts of the image. This will in most cases result in the best image quality.

•Antialiasing will minimize distortion known as aliasing, which happens when a high-resolution image is represented at a lower resolution.

The H.264 compression, in particular, provides a significant reduction in bandwidth and storage requirements while maintaining exceptional video quality, making it an ideal choice for environments where efficiency is crucial.

Equipped with a two-way audio feature, the Q7401 enables real-time communication between the camera and the control center, enhancing situational awareness and response capabilities. This feature is increasingly valuable in security applications, allowing operators to interact proactively with on-site personnel or potential intruders.

The Q7401 also includes advanced features such as video motion detection, which allows the user to set up alerts based on detected motion within predefined areas. This capability reduces the need for constant monitoring, automatically notifying users of potential security breaches or events of interest.

In terms of connectivity, the Axis Q7401 is designed to integrate seamlessly with Axis' network video products. Its compatibility with various Axis applications enhances its functionality, allowing for advanced analytics and intelligent features that can further enhance security measures.

The robust design of the Q7401 ensures reliability in various environments. Its compact form factor allows for easy installation in space-constrained locations, and it operates efficiently in temperature variations, making it suitable for both indoor and outdoor use.

Additionally, the device supports Power over Ethernet (PoE), simplifying the installation process by allowing both power and data transmission through a single cable, thus reducing the amount of wiring required.

Overall, the Axis Communications Q7401 is an excellent choice for organizations looking to upgrade their surveillance systems to meet modern security demands while benefiting from advanced features and reliable performance.
