It's good to have the camera mounted as close to face level as possible and no more than 10 feet away from a person's face at the desired point of capture. If the camera is mounted too high on a ceiling or too far away then the feature will not work properly. Furthermore, if you're using this for unique people counting, we generally recommend mounting above an exit door to capture people as they leave a building. Facing inwards often provides the best lighting whereas if you're pointing towards the door their can be bad back-lighting.
To optimize the capture of faces, make sure to adjust the zoom level of the camera. This will help ensure the camera is getting the best views of faces as possible.
This article will give you more details on the max distance your camera can automatically recognize a face.
If you have any question, talk to your Rhombus representative and they will offer a free consultation.
Once facial recognition is enabled, you'll notice a few things. First, you'll see a "Recent Faces" section on the dashboard that is meant to show you recent faces that any camera with facial recognition enabled has seen. If faces are not showing up, ensure the camera positioning is good and that a license is applied.
Saving a face means you are building a face profile for that person. To save a face, you simply have to name it.
Find the person you want to name, and click on the pencil icon.
The you'll be able to enter the name you want.
Once named, the face will appear in the 'Saved Faces' tab.
If you want to unsaved a face, simply erase the name and leave it blank.
Now, if you go into Investigations -> Faces, you'll be able to manage the Face Profiles that are saved for your organization.
With each face there are multiple options you can take. You can choose to "Trust" the face by clicking the Green check under them. This will trust all instances of that person and furthermore you can fill in their name for future reference. You can choose to do nothing which is the middle icon under them, or you can choose to create an alert any time this person is seen anywhere (only on facial recognition enabled cameras). The different states are shown by the orange arrows below.
If you want to see all sightings of a person, simply click on one of their thumbnail icons, and click "Face Details". This will show you all sightings of that person over a specified period of time. If within "Face Details" you see an incorrect match, you can choose the "Incorrect Match" link and that will automatically dismiss that match. The system will learn with each correct and incorrect match and get better at identifying each individual.
If you setup a face alert on any person, any time that face is spotted, an alert (email, push notification, etc) will be sent to all people that are to be notified of alerts. An alert can be removed at any time by either marking the person as Trusted or Ignored (grey icon in middle).
If a face is auto-tagged as the wrong person under the Recent Sighting tab, simply click on the name and name them to the correct person. Furthermore, if you go into the Details of a person and see someone that is incorrectly marked as them, simply click the circle with dots and click "Incorrect Match". With a little bit of teaching, the system will get better at identifying people correctly.
On the Faces tab of the Investigations page, you will see the “Upload Faces” button on the top right of the screen.
To get the best results, please upload 3-10 photos of each person: driver’s license, agency photo, etc.
The file name should be in the following format: First-Last_1.jpg; for example: John-Smith_1.jpg
- The dash between first and last name will be read as a space by the console.
- The 1 after the underscore is the identifier – so 1 is the first photo, 2 would be the second, and so on… they will all index as John Smith.
Once photos are uploaded of John Smith, his face will be recognized as John Smith once seen by the camera. You will not have to re-enter his name.
If John Smith has already been seen by the camera and identified as John Smith, and you would also like to upload images, you can use the image uploader to do so. Capitalization must match – uploading images as John-Smith_1.jpg will index into the pre-named face of John Smith already seen by the camera. Uploading images as john-smith_1.jpg will create another face record for john smith.
