I have created an app that supports ONVIF compatible video cameras. The cameras must support the following requirements:
- S and T profiles of the ONVIF specification,
- Provide a snapshot URL to obtain a JPEG snapshot,
- Support Pull points for motion capabilities. (version 0.0.22 adds WS_BasicEvents, also known as Push points, but is not fully tested).
The main differences between this app and the Homey IP camera support are discovery and motion detection.
There are two snapshot views for each camera, the ‘live’ image and one at the point that the last motion was detected (or delayed by a user specified amount after the motion detection). Motion will also generate a trigger for flows and both snapshots are available as tags to be used with other action cards. That allows you to send the image to your phone, etc.
I will attempt to publish it so just need to see if Athom will allow it.
The app is now live. The release version is here:
Sometimes there may be a test version available here:
Not all cameras support motion detection via ONVIF, even if they have motion detection capabilities. Sometimes this is because the manufacture does the motion detection offline rather than in the actual camera. Other times it is just because they have not implemented the Pull Points part of the specification.
Cameras known to be test so far:
- H.View HV-E800
- Unbranded HI3516EV200
- FOSCAM FI9900EP V5 (does not support motion detection via ONVIF)
- DBPOWER hd Cam: Chinese cheap outdoor cam full HD, already included in Homey, immediately recognise and working with your app, I did not test the motion alarm yet
- IMOU IPCG22: new full HD outdoor cam, already included in Homey, IP recognise but it returns the following error - Cannot read property ‘width’ of undefined
- EBITCAM F220: outdoor full HD cam, IP not recognised - I’m sure this cam needs a token to grab a snapshot so it may be not usable with your app
- Dahua DH-SD22204t-GN-W and Dahua HDBW1320E are working with version 0.0.22.
- Neo CoolCam NIP-55 working
- HiKam S6 does not have a still image URL so not possible to show either image in Homey.
- Chinese unbranded DG-MYQ, motion works but no image URL.
- Eminent EM6330 cameras are working but No ONVIF motion detection.
- Milesight 360 panoramatic
- Imou Ranger iq (IPC‑A26HIP) fully working
- Imou Looc (IPC-C26E) fully working
- Imou New Bullet (IPC-G26E) fully working
- Reolink RLC-410W fully working
- Reolink RLC-520 fully working
- HikVision DS-2CD2183G0-I
- Imou bullet lite, not detected.
- Imou cue 2, no snapshot or motion.
- TP-Link C100, no snapshot.
- IMOU Cube 4MP (IPC-K42P) Works in Homey.
If you have experience with other cameras that either fully work, partially work, or don’t work please reply to this topic with the details and I will update the list.
**To add a camera, ** use the standard add device method of Homey.
During the process, the app should discover all the ONVIF cameras on you LAN and present the list to you. This can take about 15 seconds so please be patient.
Version 1.1.18 and later add an entry on the end which is an option to manually add a camera by specifying the IP and port required to connect.
Once the list is displayed you can select one camera to add and then tap Next. You will see the screen to enter the camera login credentials (note some cameras have different credentials for ONVIF and standard access). If you chose the manual entry, then you also enter the IP and port number. Once you have entered the details, select Next. The app will try to login to the camera to verify the credentials and if all goes well the camera will be added.
If the ‘Camera’ is actually an NVR that supports multiple cameras by channel number, you will see an extra list of cameras connected to the NVR. You can then select which of these cameras are added to Homey.
If you have any issues, then the app has a Diagnostics Log feature that can be switched on in the Apps - Configure app section:
Switch the logging on by ticking the LOG ENABLED option. The setting is remembered through app restarts so it can be used to log the complete start up process.
The log is limited to 30kB at which point it will remove the first 5kB to make space for more information.
Note: Logging will add extra load to Homey so it is recommended not to keep it switched on all the time.
You can clear the log if required by taping on Clear Log and you can send the log to me by taping on Send Log. You will see a confirmation message before sending the log. Only the information in the log window is sent and there is no identifiable information included so if you are reporting a problem then please contact me either on here, via a PM or on GitHub to follow up on the problem.
The app looks like this:
Image from the last motion event (drop list set to MOTION EVENT)
Image from last snapshot (drop list set to SNAPSHOT).
This can be refreshed at any time by pressing the round arrows below the image.
It is possible to enable / disable the motion detection here (the image shows motion detection switched off): When the motion is switched off, the trigger will not activate, and the image will not update unless you use a flow card action.
You can view the current state of the alarms, etc:
The OFFLINE alarm is triggered if the app has recently lost communication with the camera. It can take up to 30 seconds to detect. After about 1 to 2 minutes the app shows ‘Not Available’.
This could mean the camera has been disconnected or the IP address has changed. If the IP address has changed you can use the Repair option to redetect the camera or change it manually in the advanced settings (see below).
The CAMERA TIME is the time reported by the camera. However, the Event times are taken from Homey.
Taping on the cog (top right of the images) takes you to the settings screen:
Here are the standard Name and Zone settings plus you can open the Advanced settings:
The Username and Password are the credentials required to log into the camera via ONVIF. Check your camera settings to make sure this has been setup.
Camera Enabled: You can temporarily disable a camera if required. This will halt the online / tamper checks, etc. If you are going to disconnected a camera for any length of time then it will save some processing time if you disable it. Also if you have a problem camera that you want to capture logs for, disabling all the other cameras can reduce the amount of ‘noise’ in the logs and make it easier to debug.
Device Class: If the class is set to Sensor then you will see the red triangle in the tile when motion is detected. If you set it to Camera then it is possible to configure some dashboards to show the camera image on the main display.
Single: when set, this option determines if just one snapshot per new trigger is captured, e.g., the trigger must be cleared by the camera before another image is captured. if it is not set then an image is captured each time a new motion event is triggered even if the last one is still active.
Delay: this is the time before the image is captured after the trigger is enabled. Some cameras are overly sensitive and will trigger before the person has fully entered the image, in which case you might only get the edge of them.
Channel: If the IP is an NVR that supports multiple cameras on channels, this field shows the channel number of the camera and can be changed. Set to -1 to prevent the channel number being changed if it is not an NVR.
Token: If the IP is for an NVR that supports multiple cameras on channels, the event notification will include a Token to identify which camera has sent the notification. This should be filled in during the pairing process, but can be changed or set if required.
Prefer Pull Events: When a camera supports both Pull and Push events, the app will use Push events by default. Switch this option is on to override that and force the app to use Pull events. Push events are more efficient then Pull events but there may be times that they won’t work, such as on different VLANS.
Time format: allows you to choose from a few options for the time and date shown on the alarms view. The default is Short HH:MM DD-MM which is a format that fits the space provided by the view on most phones.
The last section mainly shows information about the camera provided during pairing, but there are a few options that can be changed:
USER Snapshot URL: If you enter a URL in this field, it will override the one returned by the camera.
ONVIF Motion Notification to use: Some cameras support multiple notification events. They are listed in the field above this entry. Even though a particular type is supported, it might not be enabled in the camera, plus some types are more reliable than others. If you are not getting notified for motion then try selecting a different option here. If you are getting false notifications, e.g. events when the light changes or a bush moves in the wind, then try selecting a different option.
Event Object ID: For cameras that support regions of face recognition, etc, they might send an Object ID to identify the region or face. If this field is empty then any ID will generate an event. If an ID is specified then it must match the ID sent in the event notification. You can specify multiple ID’s by separating them with a comma, in which case an event will be generated if any one of the specified ID’s is received.
The Maintenance screen has an option to set the cameras time to the same as Homey and an option to run the repair routine:
Motion image is ready within… flow condition
This Condition card can be added to the AND section of the flows. It allows you to wait for the image to be capture before running the Action cards.
So, to use it you would first trigger the motion capture with the relevant Action card in a flow. This might be in response to an external motion sensor for example. Then in another flow that is triggered by, say, the doorbell button press for example, you would add this card to the And section to make sure the image is ready to send to your phone, etc by the Action cards.
