AXIS M3007–PVideo• Baseline. The Baseline profile is recommended for clients that don’t support CABAC entropy coding.• Main. The Main profile provides higher compression with maintained video quality compared to the Baseline profile butrequires 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 imagecomplexity, using up more bandwidth for increased activity in the image, and less for lower image activity. When the activity inthe scene increases, the bit rate would usually increase as well. If there is a surplus in bandwidth, this may not be an issue andselecting Variable bit rate (VBR) will be sufficient. But if bandwidth is limited, it is recommended to control the bit rate by selectingConstant bit rate (CBR). When the activity in the scene increases, VBR adjusts the bit rate according to the complexity, using upmore bandwidth for increased activity in the scene, and less for lower scene activity. CBR allows you to set a target bit rate thatlimits 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 bounceup and down within the set target but when it nears the set target value, the limitation kicks in. However, because CBR will alwaysprioritize a continuous video stream, it allows temporary overshoots from the target bit rate. Because setting a target value preventsthe bit rate from increasing, frame rate and image quality are affected negatively. To partly compensate for this, select which variableshall 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.To apply the settings, click Save.MJPEGSometimes the image size is large due to low light or complex scenery. Adjusting the maximum frame size helps to control thebandwidth and storage used by the Motion JPEG video stream in these situations. Setting the frame size to the Default settingprovides consistently good image quality at the expense of increased bandwidth and storage usage in low light. Limiting the framesize 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 ProfilesA stream profile is a set of predefined stream settings including resolution, compression, frame rate and overlay settings. Streamprofiles can be used:• When setting up recording using action rules. See Events on page 34.• When setting up continuous recording. See Continuous Recording on page 39.• 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. Ifrequired, 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 SettingsThe Video > Camera Settings page provides access to advanced image settings for the Axis product.Image AppearanceIncreasing the Color level increases the color saturation. The value 100 gives maximum color saturation. The value 0 gives ablack and white image.The image Brightness can be adjusted in the range 0–100, where a higher value produces a brighter image.20
