AXIS M5000-G PTZ CameraThe web interfaceLock aperture : Turn on to keep the aperture size set by the Aperture slider. Turn off to allow the camera to automaticallyadjust the aperture size. You can, for example, lock the aperture for scenes with permanent light conditions.Aperture : Use the slider to adjust the aperture size, that is, how much light passes through the lens. To allow more lightto enter the sensor and thereby produce a brighter image in low-light conditions, move the slider towards Open. An open aperturealso reduces the depth of field, which means that objects close to or far from the camera can appear unfocused. To allow more ofthe image to be in focus, move the slider towards Closed.Exposure level: Use the slider to adjust the image exposure.Defog : Turn on to detect the effects of foggy weather and automatically remove them for a clearer image.NoteWe recommend you not to turn on Defog in scenes with low contrast, large light level variations, or when the autofocus isslightly off. This can affect the image quality, for example, by increasing the contrast. Furthermore, too much light cannegatively impact the image quality when defog is active.GeneralName: Enter a name for the selected camera.StreamGeneralResolution: Select the image resolution suitable for the surveillance scene. A higher resolution increases bandwidth and storage.Frame rate: To avoid bandwidth problems on the network or reduce storage size, you can limit the frame rate to a fixed amount.If you leave the frame rate at zero, the frame rate is kept at the highest possible rate under the current conditions. A higherframe rate requires more bandwidth and storage capacity.Compression: Use the slider to adjust the image compression. High compression results in a lower bitrate and lower image quality.Low compression improves the image quality, but uses more bandwidth and storage when you record.Signed video : Turn on to add the signed video feature to the video. Signed video protects the video from tampering byadding cryptographic signatures to the video.ZipstreamZipstream is a bitrate reduction technology, optimized for video surveillance, that reduces the average bitrate in an H.264 or H.265stream in real time. Axis Zipstream applies a high bitrate in scenes where there are multiple regions of interest, for example, in sceneswith moving objects. When the scene is more static, Zipstream applies a lower bitrate, and thereby reduces the required storage.To learn more, see Reducing the bit rate with Axis Zipstream25
