  2. If the device doesn’t have automatic rotation of the view, log in to the webpage and go to Settings > System > Orientation.

  3. Click .

  4. Rotate the view 90° or 270°.

Find out more at axis.com/axis-corridor-format.

Verify the pixel resolution

To verify that a defined part of the image contains enough pixels to, for example, recognize license plates, you can use the pixel counter.

  1. Go to Settings > System > Orientation.

  2. Click .

  3. In the camera’s live view, adjust the size and position of the rectangle around the area of interest, for example where you expect license plates to appear.

    You can see the number of pixels for each of the rectangle’s sides (X and Y), and decide if the values are enough for your needs.

View area

A view area is a cropped part of the full view. You can stream and store view areas instead of the full view to minimize bandwidth and storage needs. If you enable PTZ for a view area, you can pan, tilt and zoom within it. By using view areas you can remove parts of the full view, for example, the sky.

When you set up a view area, we recommend you to set the video stream resolution to the same size as or smaller than the view area size. If you set the video stream resolution larger than the view area size it implies digitally scaled up video after sensor capture, which requires more bandwidth without adding image information.

Handle scenes with strong backlight

Dynamic range is the difference in light levels in an image. In some cases the difference between the darkest and the brightest areas can be significant. The result is often an image where either the dark or the bright areas are visible. Wide dynamic range (WDR) makes both dark and bright areas of the image visible.

Image without WDR.
Image with WDR.
Note
  • WDR can cause artifacts in the image.
  • WDR may not be available for all capture modes.
  1. Go to Settings > Image > Wide dynamic range.

  2. Turn on WDR.

  3. Use the Local contrast slider to adjust the amount of WDR.

  4. If you still have problems, go to Exposure and adjust the Exposure zone to cover the area of interest.

Find out more about WDR and how to use it at axis.com/web-articles/wdr.

Overlays are superimposed over the video stream. They are used to provide extra information during recordings, such as a timestamp, or during product installation and configuration. You can add either text or an image.

Show a text overlay in the video stream when the device detects motion

This example explains how to display the text “Motion detected” when the device detects motion.

How to show text overlay when the camera detects motion

Make sure that AXIS Video Motion Detection is running:

  1. Go to Settings > Apps > AXIS Video Motion Detection.

  2. Start the application if it is not already running.

  3. Make sure you have set up the application according to your needs.

  15. Set the duration.

  16. Click Save.

Bitrate control

Bitrate control helps you to manage the bandwidth consumption of your video stream.

Variable bitrate (VBR)Variable bitrate allows the bandwidth consumption to vary depending on the level of activity in the scene. The more activity, the more bandwidth you need. With variable bitrate you are guaranteed constant image quality, but you need to make sure you have storage margins.

Maximum bitrate (MBR)Maximum bitrate lets you set a target bitrate to handle bitrate limitations in your system. You might see a decline in image quality or frame rate as the instantaneous bitrate is kept below the specified target bitrate. You can choose to prioritize either image quality or frame rate. We recommend that you configure the target bitrate to a higher value than the expected bitrate. This gives you a margin in case there is a high level of activity in the scene.

  1. Target bitrate

Average bitrate (ABR)With average bitrate, the bitrate is automatically adjusted over a longer period of time. This is so you can meet the specified target and provide the best video quality based on your available storage. Bitrate is higher in scenes with a lot of activity, compared to static scenes. You are more likely to get better image quality when in scenes with a lot of activity if you use the average bitrate option. You can define the total storage required to store the video stream for a specified amount of time (retention time) when image quality is adjusted to meet the specified target bitrate. Specify the average bitrate settings in one of the following ways:

  • To calculate the estimated storage need, set the target bitrate and the retention time.

  • To calculate the average bitrate, based on available storage and required retention time, use the target bitrate calculator.

    1. Target bitrate
    2. Actual average bitrate
  • You can also turn on maximum bitrate and specify a target bitrate within the average bitrate option.
    1. Target bitrate
    2. Actual average bitrate

Video compression formats

Decide which compression method to use based on your viewing requirements, and on the properties of your network. The available options are:

Motion JPEG

Motion JPEG, or MJPEG, is a digital video sequence that is made up of a series of individual JPEG images. These images are then displayed and updated at a rate sufficient to create a stream that shows constantly updated motion. For the viewer to perceive motion video the rate must be at least 16 image frames per second. Full motion video is perceived at 30 (NTSC) or 25 (PAL) frames per second.

The Motion JPEG stream uses considerable amounts of bandwidth, but provides excellent image quality and access to every image contained in the stream.

H.264 or MPEG-4 Part 10/AVC

Note

H.264 is a licensed technology. The Axis product includes one H.264 viewing client license. To install additional unlicensed copies of the client is prohibited. To purchase additional licenses, contact your Axis reseller.

H.264 can, without compromising image quality, reduce the size of a digital video file by more than 80% compared to the Motion JPEG format and by as much as 50% compared to older MPEG formats. This means that less network bandwidth and storage space are required for a video file. Or seen another way, higher video quality can be achieved for a given bitrate.

Reduce bandwidth and storage

Important

If you reduce the bandwidth it can result in loss of details in the picture.

  1. Go to live view and select H.264.

  2. Go to Settings > Stream.

  3. Do one or more of the following:

    • Turn on the Zipstream functionality and select the desired level.

    • Turn on dynamic GOP and set a high GOP length value.

    • Increase the compression.

    • Turn on dynamic FPS.

Set up network storage

  1. To store recordings on the network, you need to set up your network storage.
  2. Go to Settings > System > Storage.

  3. Click Setup under Network storage.

  4. Enter the IP address of the host server.

  5. Enter the name of the shared location on the host server.

  6. Move the switch if the share requires a login, and enter username and password.

  7. Click Connect.

Add audio to your recording

  1. Turn on audio:
  2. Go to Settings > Audio and turn on Allow audio.

  3. Go to Input > Type and select your audio source.

  4. Edit the stream profile which is used for the recording:
  5. Go to Settings > Stream and click Stream profiles.

  6. Select the stream profile and click Audio.

  7. Select the checkbox and select Include.

  8. Click Save.

  9. Click Close.

Set up rules for events

You can create rules to make your device perform an action when certain events occur. A rule consists of conditions and actions. The conditions can be used to trigger the actions. For example, the device can start a recording or send an email when it detects motion, or show an overlay text while the device is recording.

To learn more, check out our guide Get started with rules for events.

Trigger an action

  1. Go to Settings > System > Events to set up a rule. The rule defines when the device will perform certain actions. Rules can be setup as scheduled, recurring, or for example, triggered by motion detection.

  2. Select the Condition that must be met to trigger the action. If you specify more than one condition for the rule, all of the conditions must be met to trigger the action.

  3. Select which Action the device should perform when the conditions are met.

Note

If you make changes to an active rule, you have to restart the rule for the changes to take effect.

Note

If you change the definition of a stream profile that is used in a rule, you have to to restart all the rules that use that stream profile.

Technical issues, clues and solutions

If you can’t find what you’re looking for here, try the troubleshooting section at axis.com/support.

Problems upgrading the firmware

Firmware upgrade failure

If the firmware upgrade fails, the device reloads the previous firmware. The most common reason is that the wrong firmware file has been uploaded. Check that the name of the firmware file corresponds to your device and try again.

Problems setting the IP address

The device is located on a different subnet

If the IP address intended for the device and the IP address of the computer used to access the device are located on different subnets, you cannot set the IP address. Contact your network administrator to obtain an IP address.

The IP address is being used by another device

Disconnect the Axis device from the network. Run the ping command (in a Command/DOS window, type ping and the IP address of the device):

  • If you receive: Reply from <IP address>: bytes=32; time=10... this means that the IP address may already be in use by another device on the network. Obtain a new IP address from the network administrator and reinstall the device.

  • If you receive: Request timed out, this means that the IP address is available for use with the Axis device. Check all cabling and reinstall the device.

Possible IP address conflict with another device on the same subnet

The static IP address in the Axis device is used before the DHCP server sets a dynamic address. This means that if the same default static IP address is also used by another device, there may be problems accessing the device.

The device cannot be accessed from a browser

Cannot log in

When HTTPS is enabled, ensure that the correct protocol (HTTP or HTTPS) is used when attempting to log in. You may need to manually type http or https in the browser’s address field.

If the password for the user root is lost, the device must be reset to the factory default settings. See Reset to factory default settings.

The IP address has been changed by DHCP

IP addresses obtained from a DHCP server are dynamic and may change. If the IP address has been changed, use AXIS IP Utility or AXIS Device Manager to locate the device on the network. Identify the device using its model or serial number, or by the DNS name (if the name has been configured).

If required, a static IP address can be assigned manually. For instructions, go to axis.com/support.

Certificate error when using IEEE 802.1X

For authentication to work properly, the date and time settings in the Axis device must be synchronized with an NTP server. Go to Settings > System > Date and time.

The device is accessible locally but not externally

To access the device externally, we recommend using one of the following applications for Windows®:

  • AXIS Companion: free of charge, ideal for small systems with basic surveillance needs.

  • AXIS Camera Station: 30-day trial version free of charge, ideal for small to mid-size systems.

For instructions and download, go to axis.com/vms.

Problems with streaming

Multicast H.264 only accessible by local clients

Check if your router supports multicasting, or if the router settings between the client and the device need to be configured. The TTL (Time To Live) value may need to be increased.

No multicast H.264 displayed in the client

Check with your network administrator that the multicast addresses used by the Axis device are valid for your network.

Check with your network administrator to see if there is a firewall preventing viewing.

Poor rendering of H.264 images

Ensure that your graphics card is using the latest driver. The latest drivers can usually be downloaded from the manufacturer’s website.

Color saturation is different in H.264 and Motion JPEG

Modify the settings for your graphics adapter. Go to the adapter’s documentation for more information.

Lower frame rate than expected

  • See Performance considerations.

  • Reduce the number of applications running on the client computer.

  • Limit the number of simultaneous viewers.

  • Check with the network administrator that there is enough bandwidth available.

  • Lower the image resolution.

  • The maximum frames per second is dependent on the utility frequency (60/50 Hz) of the Axis device.

Performance considerations

When setting up your system, it is important to consider how various settings and situations affect the performance. Some factors affect the amount of bandwidth (the bitrate) required, others can affect the frame rate, and some affect both. If the load on the CPU reaches its maximum, this also affects the frame rate.

The following factors are the most important to consider:

  • High image resolution or lower compression levels result in images containing more data which in turn affects the bandwidth.

  • Rotating the image in the GUI will increase the product's CPU load.

  • Access by large numbers of Motion JPEG or unicast H.264 clients affects the bandwidth.

  • Simultaneous viewing of different streams (resolution, compression) by different clients affects both frame rate and bandwidth.

    Use identical streams wherever possible to maintain a high frame rate. Stream profiles can be used to ensure that streams are identical.

  • Accessing Motion JPEG and H.264 video streams simultaneously affects both frame rate and bandwidth.

  • Heavy usage of event settings affects the product’s CPU load which in turn affects the frame rate.

  • Using HTTPS may reduce frame rate, in particular if streaming Motion JPEG.

  • Heavy network utilization due to poor infrastructure affects the bandwidth.

  • Viewing on poorly performing client computers lowers perceived performance and affects frame rate.

  • Running multiple AXIS Camera Application Platform (ACAP) applications simultaneously may affect the frame rate and the general performance.
