OS 2.0.3 release notes
Our OS is a standardized operating system for IP cameras that include a supported system on a chip (SoC). It is based on the Android Open Source Project (AOSP) and has been customized for use in embedded devices by our hardware partners. It includes our APIs and OS components.
Our new release OS 2.0.3 comes with a number of new features, improvements and fixes.
- Azena OS now supports MediaTek MTK8192 SoC.
- Azena OS supports AOSP 10 (API level 29).
- Hardware acceleration of Machine learning models via Neural Networks API (NNAPI) is now available across supported devices.
- Video-FeedIn enables testing and benchmarking by injecting external test streams.
- New version of the WebHelpers Library released
- Added Message Ports as a device capability
- Fixed strange colors on Altek RefCam due to faulty IR setting
- ADB is available in developer mode, after reboot
- Fixed loosing the deviceId after factory reset
- Fix boot fail for headless system.
- Camera calibration data can now be used by Apps from an OS-defined Calibration Service.
Apps can now relate pixel data to physical dimensions on a calibrated camera. The Calibration Service was introduced to make calibration data accessible. Some of the calibration data, such as horizontal and vertical pixel pitch, principal point, skew factor and distortion coefficients should be provided by the manufacturer.
- Introduced Intrinsic Calibration Tool, for optional use by the user to (re)calibrate the camera.
- Introduced Calibration WebUI to access the Intrinsic Calibration Tool and status of the calibration, for both intrinsic and extrinsic calibration.
- New Coordinate system API to support multi-camera object tracking.
Easy mapping of points, lines, planes etc. between 2D and 3D space and exchanging real-world locations between Apps and cameras is now available by using the new Coordinate System API. Apps can use that API on calibrated cameras to enable object tracking over different cameras.
FrameMetadataclass is extended with lens
DevicePropertiesclass which contains device-related information has been introduced. For now it provides the device ID through the
WebServerManager.setActiveCertificateForHostnameshas been introduced to add server name indication mappings between the hostnames of a certificate and the alias of that certificate itself. The
CN fieldand/or the subject alternative names of a certificate are used as hostnames. The
WebServerManager.removeActiveCertificateForHostnameshas been introduced to remove all server name indications mappings to the specified certificate.
- Backing up and restoring App configuration is now supported by REST APIs.
To perform application data backups and restores, a set of APIs was introduced which can be used by Video Management Systems, the Device Management Tool (DMT), and other external clients.
- Fixed race-condition that could cause the first application backup/restore after booting the device to fail.
- Based on AOSP 10.
- Supports networking for Apps.
- Boot animation update.
- Fixed high CPU usage when booting on emulator.
- Introduced APIs in Event service to set/get/remove
- APK snatch event is logged on IDS page.
- New I/O Commander enables you to assign control over external devices connected to the camera.
I/O Commander selection is now enabled. Applications that need to control I/O devices must register themselves as I/O Commanders. Users can choose among the registered commanders to grant control over the I/O devices in the camera. The default Commander is ONVIF. Calls made to the I/O devices from any application other than the selected I/O Commander will fail.
com.securityandsafetythings.iointroduces a new interface,
IController. Manufacturer-owned system services can implement this interface to make their I/O HAL implementations available to the
IoService. By doing this, all calls from the
IoServiceto the lower layers are sent to the external system service, instead of the default (internal) GPIO HAL.
- Introduced GPIO HAL3.0 that makes use of xsd template and xml file instead of
- Delay field in action is shown and configurable only for activating relays in Monostable mode.
- Delay field in relay configuration is not applicable for I/O Switchboard and it is thus hidden from the user interface.
- Relay state is ensured to be deactivated when moving the mode of the relay from bistable to monostable.
- The device and action list immediately auto-refreshes after changing the configurations using I/O Switchboard user interface.
- Stabilized IO Service database initialization with more exception handling.
- Additional HTTP capabilities are now available to the IoT Gateway
REST IoT Gateway now supports custom HTTP headers and payload overriding. Users can specify their own HTTP headers while creating or updating the REST connection. Furthermore, users have the freedom to override the message payload before sending it out.
- QoS capabilities are now available to the IoT Gateway
MQTT IoT Gateway now support payload overriding and QoS selection. Users can override the message payload and specify MQTT Quality of Service (QoS - QoS2 is the default) while creating or updating the MQTT connection.
- Topic mapping to translate topic of the Outgoing/Incoming message to a new topic.
- In REST IoT Gateway, on server mode, returns an empty response for the Outgoing Topics that do not have a corresponding message published yet.
- Mqtt Gateway Delete requires disconnecting to be clicked when auto-reconnect is set to false.
- In MQTT IoT Gateway, connections with auto-reconnect disabled can now be deleted when the connection with the MQTT broker is lost and the connection is in the disconnected state.
- Added Stream Provider.
- Added Streaming from Virtual Base Cameras.
- Live 555 Update.
- Stream Configuration is changed to contain the UUID of the associated Video Capture.
- Fix for MediaService Crash Metadata Stream.
- Make RTSP server wait streaming until stream info is available.
- New Message Ports API for enhanced inter App communication.
Introduced Message Ports for inter App communication. Message Ports provides interfaces to
InPortenabling applications to send and receive messages.
- New AppGraphBuilder to manage information flow between Message Ports.
Introduced AppGraphBuilder to manage and control information flow between message ports registered in the device. Apps on the device can now easily be connected.
- Introduced APIs in Message class to get/set the timestamp for a message.
- Fix for sporadic Messaging Service crash on app stop from the overview page.
- Comments in MessagingManifest.xml causes no errors.
- Factory default IP address added for improved camera setup.
Introduced a static IP fallback mechanism to make sure that the wired network interface has always an IP address on the first boot of the camera after a factory reset. If no IP address is assigned within 1 minute from booting, static IP address 192.168.0.111/16 is assigned. To later switch to a newly available DHCP service, modify the network settings via the WebUI and switch the IP assignment to 'automatic'.
- ONVIF Profile S and T are displayed by default.
- ONVIF Media2, Imaging, DeviceIO and AdvancedSecurity services displayed by default.

- Announce only default VideoSourceConfigurations.
- Add default `tt` namespace prefix for datatype values, which are defined with no namespaces, in the Type field in event messages.
- Support for Fisheye cameras with multiple dewarped sub-streams:
Feature ‘Virtual Base Cameras’ has been added, which allows splitting the sensor video feed into multiple streams that can be transformed through a pluggable Shader module. This feature is mainly intended for Fisheye type sensors that require the extraction of a region of interest and subsequent transformation before further processing.
- Added support for Virtual Base Camera Shader Modules.
- Added System API for Virtual Base Camera creation and mapping to installed Apps.
- Added new System permission to access Virtual Base Cameras.

/device/securityandsafetythings/base/configstogether with a validation schema and further information.
- The WebServer now supports SNI (server name indication). New generated or imported certificates are automatically used for the hostnames if there is no active mapping for any of the given hostnames. The
CN fieldand/or the subject alternative names from the certificate’s extensions are used as hostnames. To create or modify mappings, WebServer offers
- Certificate Management: SNI and Custom Certificate Uploads extensions.
