Connect Cameras

Configure Gatherer ACAP to publish detections into this platform over MQTT.

ACAP MQTT Settings

  1. On the camera, open Apps and launch Gatherer.
  2. Go to the MQTT tab.
  3. Enter these values and click Connect.
Address
Port
1883
Connection mode
Direct (or Tailscale (SOCKS5) if your camera uses Prudscale/Tailscale userspace networking)
User
(blank) unless you configured auth
Password
(blank) unless you configured auth
TLS
No TLS (default)
Pre-topic
prudencia/dataset
Tip: If you are using Tailscale, set Address to the platform server's Tailscale IP (usually 100.x.y.z).
If your camera is on Tailnet via Prudscale/Tailscale userspace networking, set Connection mode to Tailscale (SOCKS5) in the ACAP UI so it can route to 100.x brokers.
Important: Address must be a bare IP/hostname only (no http:// and no :1883).
Optional: set Name and Location in the ACAP UI so the platform can show human-friendly camera info.

Topic Format

Gatherer ACAP prepends Pre-topic automatically. Your code should publish to:
prudencia/dataset/<camera_serial>/<class_label>
Example: publish <camera_serial>/person and set Pre-topic to prudencia/dataset.

Payload Contract

Single JSON message per detection. Images are base64-encoded JPEGs.

              
After the first message arrives, the camera will appear under Cameras.

Model Inspector

Upload a YOLOv5 .tflite and the platform will extract the quantization values you must enter in the Gatherer ACAP (Model tab). This avoids running any inspection on the camera.

Upload

Tip: If you have two exports (ARTPEC-8 per-tensor and ARTPEC-9 per-channel), analyze both and save the values per camera.

Deploy ACAP Package

Uses camera HTTP API (`/axis-cgi/applications/upload.cgi`). Set per-camera credentials in the Target cameras list (cogwheel). Optional post-install bootstrap can install a license key file and configure MQTT.
