LumiCenter Facial Recognition Channel

This add-on module enables LumiCenter Plus and Max to perform real-time facial recognition from any surveillance camera, instantly matching faces against a watchlist. When a match is found from the positive lists or negative lists, the system can send alerts via UI, text, email, or API.
The watchlist database has no license-based size limit and can be synced with the cloud. The module can also trigger actions like door access or automated tasks through macros.

Features:

• Enables LumiCenter Plus and Max to run facial recognition in real time from any surveillance cameras and instantly match them against a watchlist of individuals
• Facial recognition module can send notification alert (UI, Text, Email, API) when a certain person matched the positive/negative lists
• Enrolling watchlist database size is not limited by license and can be synchronized in the cloud
• The module can initiate opening a door or other actions running a macro to automate tasks.
• A LumiCenter video license is required for each camera in addition to this add-on module

Key Technologies:

LumiCenter detects faces in video feeds and uses an AI facial recognition algorithm to generate and store vector-based mathematical representations. These vectors contain no personal identifying information and are used solely for finding similar faces in recorded footage. Face search allows rapid comparison of a person's photo against video archives, including footage from multiple cameras, significantly speeding up investigations.

Key Features:

• Search faces across multiple cameras
• Verify a person's identity using their face
• Save time during investigations
• Get alerts when a face is recognized
• Match faces and compare to positive lists and negative lists
• Initiate an action like unlocking a door based on a face

Certifications and Compliance:

• NDAA Compliant

Applications:

• Monitor a person's activity in a secured area
• Find a lost child at a shopping center
• Search for suspects and witnesses during investigations

Supported by LumiCenter:

• Plus
• Max

Face Lists

• When a recognized face is found in a specific list
• When a recognized face is not found in a specific list
• When the system needs to confirm the presence of a specific face from a list
• When the system needs to confirm the absence of a specific face from a list
• When a recognized face is not found in any list

Face Detector Functions

The Face Detector triggers an event whenever a face appears in the frame. LumiCenter stores all captured faces in binary format within its database. It is
recommended to use LumiCenter Net for each camera channel.

Face Detector Requirements

Cameras

• The camera's video stream must have a frame rate of at least 12 fps to handle standard tasks effectively. If used at turnstiles, there must be a minimum frame rate of 6 fps.
• Distortion of the face from the camera lens must be minimal, particularly at the center of the frame.

Lighting

• Faces must be evenly illuminated with diffused light of at least 200 lux. Directional side lighting cannot be used. The detector will not work if lighting is excessive or insufficient.
• Contrast of the captured faces must be over 64 grayscale.
• Backlighting and sharp gradients of light and shade cannot be present.

Scene and Camera Angle

• The maximum allowed frontal angle for captured face images is ±15° from the camera.
• Minimize overlap between faces in the frame.
• For best results, position faces near the center of the frame, where image distortion is lowest.

Object Images

• Captured face images must be clear with no motion blur.
• For creating a face vector, the distance between the pupils must be at least 32 pixels.
• For generating face tracks, the face width must be a minimum of 16 pixels.

Server Hardware:

• The Face Detector and its sub-detectors require a CPU with support for SSE4.2, FMA3, or AVX2.0 instruction sets
• If running on a GPU, the following requirements must be met:

1. The detector can only run on Nvidia devices with at least 6 GB of video memory.
2. Nvidia driver version 418.39 or higher is required.
3. Compute Capability 6.0 or higher is necessary.
