How to Build a Smart CCTV Camera with Raspberry Pi 4 and High Quality Camera

Smart CCTV cameras are becoming increasingly popular in home automation, providing enhanced surveillance and security for your valuable assets. With the new Raspberry Pi High Quality Camera, you can now make the most of face recognition technology to know who's at your door and add multiple profiles for friends and strangers. This camera can be placed indoors or on your front porch, allowing you to Interact with visitors using a dedicated monitor. Additionally, you can control home appliances, keep an eye on blind spots, and access the live stream from anywhere, receiving notifications when someone turns up at your door. In this article, we will guide you on how to build your own smart CCTV camera using the Raspberry Pi 4 and the new high quality camera.

The Benefits of Smart CCTV Camera

Smart CCTV cameras offer several advantages over traditional surveillance systems. Here are some of the key benefits:

  1. Enhanced Security: Smart CCTV cameras provide an added layer of security to your home, allowing you to monitor your surroundings and deter potential intruders.
  2. Face Recognition: With the integration of face recognition technology, smart CCTV cameras can identify familiar faces and notify You when someone unfamiliar approaches.
  3. Interact with Visitors: A dedicated monitor connected to the smart CCTV camera enables you to interact with visitors at your door, making it convenient for Package deliveries or greeting guests.
  4. Remote Access: You can remotely view the live stream from the camera on your mobile devices or other connected devices, keeping you updated on your home's security even when you're not there.
  5. Home Automation Integration: Smart CCTV cameras can be integrated with home automation systems, allowing you to control appliances and monitor blind spots within your property.

Components for Building a Smart CCTV Camera

To build your own smart CCTV camera, you will need the following components:

  • Raspberry Pi 4: The Raspberry Pi 4, preferably the 4GB version, serves as the Core component for running the CCTV camera software.
  • Camera Enclosure: A plastic CCTV camera enclosure can be repurposed to house the Raspberry Pi, camera module, and other components securely.
  • Micro SD Card: A micro SD card is required to store the operating system and software required for the CCTV camera.
  • Raspberry Pi 4 Charger: Make sure to use a USB-C charger compatible with the Raspberry Pi 4 for reliable power supply.
  • Raspberry Pi High Quality Camera: The new Raspberry Pi High Quality Camera provides improved image quality and flexibility with interchangeable lenses.
  • Six Millimeter Lens: Select a lens suitable for your monitoring needs, such as a six millimeter lens for capturing a wide viewing angle.
  • Raspberry Pi 3: A Raspberry Pi 3 is required for the dedicated touch screen monitor to interact with visitors.
  • 7 Inch Touch Screen Display: The 7 inch touch screen display allows you to view the live stream and control the smart CCTV camera's functions.
  • HDMI Cable: An HDMI cable is needed to connect the Raspberry Pi 3 to the touch screen display.
  • Micro USB Cable: A micro USB cable is used to power the 7 inch display, which is connected to the Raspberry Pi 3.

How the Smart CCTV Camera Works

The smart CCTV camera build revolves around the camera module and the Raspberry Pi. Simply insert the camera module into the camera port of the Raspberry Pi to complete the basic setup. The camera captures live footage, which can be accessed through a web stream. By using Flask, a micro web framework, the live stream can be served to client devices, including both Raspberry Pi and mobile phones, connected to the same network as the camera. This allows you to view the live footage of the stream from anywhere within the network. Compared to a traditional CCTV camera, the smart CCTV camera with its web streaming capability provides greater accessibility.

Viewing the Live Stream on Other Devices

Unlike normal CCTV cameras, the smart CCTV camera allows you to view the live stream on other devices. By capturing the live footage from the camera build and utilizing Flask, you can Create a live stream accessible on client devices, such as Raspberry Pi or mobile phones, connected to the same network. Simply visit the designated URL on the client device to see the live footage of the stream. This feature provides convenience and flexibility by enabling you to monitor your property even when you're not physically present.
