Secure passwords Important Axis devices send the initially set password in clear text over the network. To protect your device after the first login, set up a secure and encrypted HTTPS connection and then change the password. The device password is the primary protection for your data and services. Axis devices do not impose a password policy as they may be used in various types of installations.

RSA is the preferred method during negotiation, followed by ECDSA, ED25519, and DSA. Make sure to enter the right MD5 host key that is used by your SFTP server. While the Axis device supports both MD5 and SHA-256 hash keys, we recommend using SHA-256 due to stronger security over MD5. For more information on how to configure an SFTP server with an Axis device, go to the AXIS OS Portal.

The image shows how the field of view and aspect ratio can change between two different capture modes. What capture mode to choose depends on the requirements for the frame rate and resolution of the specific surveillance setup. For specifications about available capture modes, see the product’s datasheet at axis.com.
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.

AXIS Q3538–SLVE Dome Camera Learn more 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.
Actual average bitrate Applications AXIS Camera Application Platform (ACAP) is an open platform that enables third parties to develop analytics and other applications for Axis products. To find out more about available applications, downloads, trials and licenses, go to axis.com/applications.
AXIS Object Analytics AXIS Object Analytics is an analytic application that comes preinstalled on the camera. It detects objects that move in the scene and classifies them as, for example, humans or vehicles. You can set up the application to send alarms for different types of objects. To find out more about how the application works, see the user manual.

AXIS Q3538–SLVE Dome Camera Cleaning recommendations Cleaning recommendations NOTICE TICE TICE Never use harsh detergent, for example gasoline, benzene, or acetone. 1. Use a can of compressed air to remove any dust or loose dirt from the device. 2. If necessary, clean the lens with a soft cloth dampened with lukewarm water.
Using firmware from the active track is recommended if you want to access the newest features, or if you use Axis end-to-end system offerings. The LTS tracks are recommended if you use third-party integrations, which are not continuously validated against the latest active track.
3. Go to Maintenance > Firmware upgrade and click Upgrade. When the upgrade has finished, the product restarts automatically. You can use AXIS Device Manager to upgrade multiple devices at the same time. Find out more at axis.com/products/axis-device-manager. Technical issues, clues, and solutions If you can’t find what you’re looking for here, try the troubleshooting section at axis.com/support.
IP addresses obtained from a DHCP server are dynamic and may change. If the IP address has been changed by DHCP 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).
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.
