AXIS M3005-V Network CameraVideoImageThe 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 thecompression, 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.• Overlay settings. SeeOverlay on page 18.Click Save to apply the new settings.H.264H.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 whereasP-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 onbandwidth 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 imagecomplexity, using up more bandwidth for increased activity in the image, and less for lower image activity. CBR allows you to set afixed Target bit rate that consumes a predictable amount of bandwidth. As the bit rate would usually need to increase for increasedimage activity, but in this case cannot, frame rate and image quality are affected negatively. To partly compensate for this, it ispossible to prioritize either frame rate or image quality. Not setting a priority means that frame rate and image quality are equallyaffected. 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 OverlaySettings and enter the modifier #b in the field.Stream ProfilesA stream profile is a set of pre-configured stream settings including resolution, compression, frame rate and overlay settings.Stream profiles can be used:• When setting up recording using action rules, seeEvents on page 28.• When setting up a continuous recording, seeContinuous Recording on page 31.• In the Live View page — select the stream profile from the Stream profile drop-down list.Four pre-programmed stream profiles are available for quick set up. Each pre-programmed profile has a descriptive name, indicatingits purpose. If required, the pre-programmed 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.16
