Hide parts of the image with privacy masks

What is a privacy mask?

A privacy mask is a user-defined area that covers a part of the monitored area. In the video stream, privacy masks appear either as blocks of solid color or with a mosaic pattern.
You’ll see the privacy mask on all snapshots, recorded video, and live streams. You can use the VAPIX® application programming interface (API) to turn off the privacy masks.

Important

Using multiple privacy masks may affect the product’s performance. Create a privacy mask To create a privacy mask, go to Settings > Privacy mask .

Select exposure mode

There are different exposure mode options in the camera that adjusts aperture, shutter speed, and gain to improve image quality for specific surveillance scenes. Go to Settings > Image > Exposure and select between the following exposure modes:

  • For most use cases, select Automatic exposure.
  • For environments with certain artificial lighting, for example fluorescent lighting, select Flicker-free. Select the same frequency as the power line frequency.
  • For environments with certain artificial light and bright light, for example outdoors with fluorescent lighting at night and sun during daytime, select Flicker-reduced. Select the same frequency as the power line frequency.

Maximize details in an image

Important
If you maximize details in an image, the bitrate will probably increase and you might get a reduced frame rate.

  • Set the compression as low as possible.
  • Select MJPEG streaming.
  • Turn off Zipstream functionality.

Monitor long and narrow areas
Use corridor format to better utilize the full field of view in a long and narrow area, for example a staircase, hallway, road, or tunnel.

Improve license plate recognition

To better recognize the license plate of a car passing by the camera, you can apply and adjust a number of things.
One option is to use the pixel counter in your camera to set the optimal pixel resolution:

  1. Go to Settings > System > Orientation and click
  2. Adjust the size and placement of the rectangle in the camera’s live view around the area of interest, for example where the license plates of passing cars are expected to appear. You can then see the number of pixels represented by the sides of the rectangle

Note
You can use an object of a known size in the view as a reference to decide how much resolution is needed for recognition. In addition, you can try to adjust the following to optimize license plate recognition:

  • Shutter speed
  • Gain
  • Zoom

About 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.

  1. Go to Settings > Image.
  2. If required, turn on WDR under Wide dynamic range.
  3. Use the Local contrast slider to adjust the amount of WDR.

Note
WDR may cause artifacts in the image. Find out more about WDR and how to use it at axis.com/web-articles/wdr

About overlays

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.

Make the camera show a text overlay when it detects motion

This example explains how to display the text “Motion detected” when the camera detects motion: Make sure the AXIS Video Motion Detection application 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.
    Add the overlay text:

  4. Go to Settings > Overlay.

  5. Select Create overlay and select Text overlay.

  6. Enter #D in the text field.

  7. Choose text size and appearance.

  8. To position the text overlay, choose Custom or one of the presets.
    Create an action rule:

  9. Go to System > Events > Action rules.

  10. Create an action rule with AXIS Video Motion Detection as trigger.

  11. From the list of actions, select Overlay text.

  12. Type “Motion detected”.

  13. Set the duration.

Note
If you update the overlay text it will be automatically updated on all video streams dynamically

Choose video compression format
Decide which compression method to use based on your viewing requirements, and on the properties of your network. The
available options are: Motion JPEG
Note
To ensure support for the Opus audio codec, the Motion JPEG stream is always sent over RTP. 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. Installing 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 the MPEG-4 standard. 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. H.265 or MPEG-H Part 2/HEVC
Note
H.265 is licensed technology. The Axis product includes one H.265 viewing client license. Installing additional unlicensed copies of the client is prohibited. To purchase additional licenses, contact your Axis reseller.

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.
    Note
    The zipstream settings are used for both H.264 and H.265.
    – Turn on dynamic GOP and set a high GOP length value.
    – Increase the compression.
    – Turn on dynamic FPS.

Note
Web browsers do not support H.265 decoding. Use a video management system or application supporting H.265 decoding.

    To watch your recording:

  3. Click on Storage > Go to recordings.

  4. Select your recording in the list and it will play automatically.

Rules and alerts

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 when it records.

Trigger an action

  1. Go to Settings > System > Events to set up an action rule. The action rule defines when the camera will perform certain actions. Action rules can be setup as scheduled, recurring, or for example, triggered by motion detection.
  2. Select what Trigger must be met to trigger the action. If you specify more than one trigger for the action rule, all of them must be met to trigger the action.
  3. Select which Action the camera should perform when the conditions are met.
    Note
    If you make changes to an active action rule, the action rule needs to be restarted for the changes to take effect.

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 after firmware
upgrade
If you experience problems after a firmware upgrade, roll back to the previously installed version
from the Maintenance page.
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 : 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 on page 15.
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/products/axis-companion
    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 on page 17.

  • 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.
    Can’t select H.265 encoding
    in live view
    Web browsers do not support H.265 decoding. Use a video management system or application
    supporting H.265 decoding.

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.

Troubleshooting

  • Rotating the lens manually will result in better performance compared to rotating the image from the GUI.
  • 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
