Create a Smart Security and Surveillance System using MQTT Communication

10.12.2024 - Engine: Gemini

Building a Security and Surveillance System with MQTT Communication

Components Required:

• Motion sensors
• Cameras with motion detection
• MQTT broker
• Raspberry Pi or similar microcontroller
• SD card

Steps:

1. Hardware Setup:

• Install motion sensors and cameras at strategic points.
• Connect the devices to the Raspberry Pi or microcontroller.

2. Software Installation:

• Install Raspbian or another compatible OS on the Raspberry Pi.
• Install MQTT clients and libraries.

3. MQTT Broker Setup:

• Install an MQTT broker like Mosquitto on a server or separate device.
• Configure the broker and create a topic for sensor data.

4. Python Script Creation:

• Create a Python script that receives input from the sensors and publishes to the MQTT broker.
• Use the following code as a template:

import paho.mqtt.client as mqtt
import RPi.GPIO as GPIO

# MQTT Broker Configuration
broker_address = "mqtt-broker-address"
broker_port = 1883
topic = "sensor-data"

# Hardware Configuration
motion_sensor_pin = 4
camera_motion_detection_pin = 17

# Initialize MQTT Client
client = mqtt.Client()
client.connect(broker_address, broker_port)

# Setup GPIO
GPIO.setmode(GPIO.BCM)
GPIO.setup(motion_sensor_pin, GPIO.IN)
GPIO.setup(camera_motion_detection_pin, GPIO.IN)

# Receive Sensor Data and Publish to MQTT
while True:
    if GPIO.input(motion_sensor_pin):
        client.publish(topic, "Motion detected")

    if GPIO.input(camera_motion_detection_pin):
        client.publish(topic, "Camera motion detected")

5. Camera Configuration:

• Configure the cameras to detect motion and send a notification to the MQTT broker.

6. Notification Service Setup:

• Subscribe to the MQTT topic and set up a notification service like Pushover or Telegram to receive alerts.

7. Testing:

• Trigger the motion sensor and verify that a notification is received.
• Move in front of the camera and check if camera movement is detected and a notification is sent.

Additional Features:

• Automated Lighting: Configure the system to turn on lights when motion is detected.
• Cloud Storage: Integrate cloud services like AWS S3 to store video footage.
• Web Interface: Create a web interface to monitor the system and configure settings.
