# ONVIF-Java --- [  ](https://bintray.com/tomasverhelst/ONVIF-Java/ONVIF-Java/_latestVersion)

ONVIF is an open industry forum that provides and promotes standardized interfaces for effective interoperability of IP-based physical security products. ONVIF was created to make a standard way of how IP products within CCTV and other security areas can communicate with each other. ## Features - **ONVIF & UPnP discovery** - ONVIF device management (Services, device information, media profiles, raw media stream uri) - UPnP device information - Easily extendable with your own requests - **Android supported!** ## Discovery --- The OnvifDiscovery class uses the **Web Services Dynamic Discovery (WS-Discovery)**. This is a technical specification that defines a multicast discovery protocol to locate services on a local network. It operates over TCP and UDP port ```3702``` and uses IP multicast address ```239.255.255.250```. As the name suggests, the actual communication between nodes is done using web services standards, notably **SOAP-over-UDP**. With WS-Discovery, the discovery tool puts SSDP queries on the network from its unicast address to ```239.255.255.250``` multicast address, sending them to the well-known UDP port 3702. The device receives the query, and answers to the discovery tool's unicast IP address from its unicast IP address. The reply contains information about the Web Services (WS) available on the device. **UPnP** works in a very similar way, but on a different UDP port (```1900```). Compared to the WS-Discovery, the UPnP is intended for a general use (data sharing, communication, entertainment). ```java DiscoveryManager manager = new DiscoveryManager(); manager.setDiscoveryTimeout(10000); manager.discover(new DiscoveryListener() { @Override public void onDiscoveryStarted() { System.out.println("Discovery started"); } @Override public void onDevicesFound(List devices) { for (Device device : devices) System.out.println("Devices found: " + device.getHostName()); } }); ``` ## ONVIF --- With the ```OnvifManager``` class it is possible to send requests to an ONVIF-supported device. All requests are sent asynchronously and you can use the ```OnvifResponseListener``` for errors and custom response handling. It is possible to create your own ```OnvifDevice``` or retrieve a list from the ```discover``` method in the ```DiscoveryManager``` ```java onvifManager = new OnvifManager(); onvifManager.setOnvifResponseListener(this); OnvifDevice device = new OnvifDevice("192.168.0.131", "username", "password"); ``` ### Services Returns information about services on the device. ```java onvifManager.getServices(device, new OnvifServicesListener() { @Override public void onServicesReceived(@Nonnull OnvifDevice onvifDevice, OnvifServices services) { } }); ``` ### Device information Returns basic device information from the device. This includes the manufacturer, serial number, hardwareId, ... ```java onvifManager.getDeviceInformation(device, new OnvifDeviceInformationListener() { @Override public void onDeviceInformationReceived(@Nonnull OnvifDevice device, @Nonnull OnvifDeviceInformation deviceInformation) { } }); ``` ### Media Profiles Returns pre-configured or dynamically configured profiles. This command lists all configured profiles in a device. The client does not need to know the media profile in order to use the command. ```java onvifManager.getMediaProfiles(device, new OnvifMediaProfilesListener() { @Override public void onMediaProfilesReceived(@Nonnull OnvifDevice device, @Nonnull List mediaProfiles) { } }); ``` ### Media Stream URI Returns a raw media stream URI that remains valid indefinitely even if the profile is changed. ```java onvifManager.getMediaStreamURI(device, mediaProfiles.get(0), new OnvifMediaStreamURIListener() { @Override public void onMediaStreamURIReceived(@Nonnull OnvifDevice device, @Nonnull OnvifMediaProfile profile, @Nonnull String uri) { } }); ``` ## UPnP --- With the ```UPnPManager``` it is possible to retrieve device information from a locally connected UPnP device. A ```UPnPDevice``` can be created manually or discovered from the ```DiscoveryManager``` using ```discovery.discover(DiscoveryMode.UPNP)``` ```java UPnPDevice device = new UPnPDevice("192.168.0.160"); device.setLocation("http://192.168.0.160:49152/rootdesc1.xml"); UPnPManager uPnPManager = new UPnPManager(); uPnPManager.getDeviceInformation(device, new UPnPDeviceInformationListener() { @Override public void onDeviceInformationReceived(@Nonnull UPnPDevice device, @Nonnull UPnPDeviceInformation information) { Log.i(TAG, device.getHostName() + ": " + information.getFriendlyName()); } @Override public void onError(@Nonnull UPnPDevice onvifDevice, int errorCode, String errorMessage) { Log.e(TAG, "Error: " + errorMessage); } }); ``` ## Custom requests --- It is possible to implement your custom ONVIF request by creating a new class and implementing the ```OnvifRequest``` interface and overriding the ```getXml()``` and ```getType()``` methods. ```java public class PTZRequest implements OnvifRequest { @Override public String getXml() { return "" + "false" + ""; } @Override public OnvifType getType() { return OnvifType.CUSTOM; } } ``` and send it to the appropriate ```OnvifDevice```: ```java onvifManager.sendOnvifRequest(device, new PTZRequest()); ``` Use the ```OnvifResponseListener``` to receive responses from your custom requests. ## Android --- In order to receive multicasts packets on your Android device, you'll have to acquire a lock on your WifiManager before making a discovery. Make sure to release the lock once the discovery is completed. More information can be found here: https://developer.android.com/reference/android/net/wifi/WifiManager.MulticastLock ```java private void lockMulticast() { WifiManager wifi = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE); if (wifi == null) return; WifiManager.MulticastLock lock = wifi.createMulticastLock("ONVIF"); lock.acquire(); } ``` Download -------- Download [the latest JAR][2] or grab via Maven: ```xml be.teletask.onvif onvif 1.0.0 ``` or Gradle: ```groovy compile 'be.teletask.onvif:onvif:1.0.0' ``` ## Todos - Implementation ONVIF version management - Implementation PTZ ## Pull Requests --- Feel free to send pull requests.
