0. features

offline. no internet. local processing. registration. captures 20 face samples. duty mode. continuous surveillance. threat detection. logs unrecognized people. voice override. speak code to authorize. hardware lock. keypad entry. servo control.

1. requirements

python 3.8+ webcam / mic / speakers 2gb disk space

hardware arduino uno servo motor (pin 10) 4x4 keypad (pins 2-9)

2. setup

software

pip install -r requirements.txt

download vosk-model-small-en-us-0.15 -> rename to vosk-model.

hardware

upload ultron arduino/ultron_arduino.ino to arduino. connect:

• servo signal -> pin 10
• keypad rows -> pins 2,3,4,5
• keypad cols -> pins 6,7,8,9

3. usage

start system:

python main.py

[modes]

1 registration -> capture face samples. 2 duty mode -> start surveillance. 3 view users -> list database.

[access]

face unlock -> camera sees authorized user -> door unlocks. keypad unlock -> enter 1234 or # -> door unlocks. voice override -> threat detected? say ultron override -> door unlocks.

4. configuration

edit config.yaml.

face_match_threshold: 0.6
registration_samples: 20
admin_passphrase: "ultron override"
voice_volume: 1.0
camera_index: 0
admin_code_timeout: 10
arduino_port: "COM3"

5. status

vosk model not found -> check folder name vosk-model. arduino missing -> check usb connection + config COM port. no audio -> ensures tts_worker.py exists (subprocess mode).

6. security

data is local. sqlite database. raw images stored. no network. keep config.yaml safe.
