The future outlook for the ip camera soc market is bright for on-device AI processing. Your sensor will feed data to the SoC for processing. The sensor and SoC work together. A good sensor is vital for quality video.

DESIGNING THE IMAGING SYSTEM

Your SoC needs high-quality data to perform well. The imaging system provides this data. It includes the image sensor, lens, and filter. You can build a great imaging system for your AI camera for under $15. Your goal is to capture clear video for the SoC to analyze. A good sensor and lens are crucial for the camera's overall performance. The sensor works directly with the SoC to enable powerful AI features.

Sensor Selection and Trade-offs

You should choose a 2-megapixel (2MP) to 4-megapixel (4MP) image sensor. This resolution gives you a good balance between image detail and cost. Top suppliers like Sony (with their STARVIS line) and OmniVision offer excellent sensor options. You can find a quality sensor from these brands for under $10. This sensor choice directly impacts the AI performance of your camera. The sensor feeds the SoC the visual information it needs for complex image processing.

Note: Your project's needs determine the right sensor. A higher-resolution sensor costs more but is necessary for tasks like reading license plates. Your choice affects the final performance of the AI camera. Consider these factors:

• Camera Resolution: A lower-resolution sensor is fine for general surveillance tasks like counting people. This keeps your sensor cost down.
• Frames Per Second (FPS): A camera for tracking fast objects needs a high FPS sensor, which is more expensive. For most simple surveillance, a standard FPS sensor is enough.
• Specialized Hardware: Some AI tasks need depth information, requiring expensive stereo cameras. Your HiSilicon SoC can estimate depth from a standard sensor, saving you money.

A 2MP-4MP sensor provides enough detail for the SoC to run many AI applications effectively. This sensor choice helps you manage your budget while maintaining strong performance. The sensor is the eye of your camera, and its performance is vital.

Lens and Filter Cost Savings

You can source a quality M12 glass lens and a standard IR-cut filter for about $5 combined. A glass lens gives you a sharper image and better durability than a plastic one. The lens focuses light onto the sensor, so its quality is important for clear video.

For the lens, sample prices are often a few dollars. However, costs drop when you buy more. This makes the camera much cheaper to produce at scale. The SoC relies on the lens and sensor to deliver a clean image.

You also need an IR-cut filter. This small component ensures colors look accurate in daylight. While some high-performance filters cost over $60, you do not need one for this project. You can find a standard filter compatible with your M12 lens for just $1 to $2 from the same suppliers. This keeps your camera affordable without hurting its core performance. The SoC will receive a color-accurate image from the sensor.

OPTIMIZING MEMORY AND STORAGE

You must select the right memory and storage for your AI camera. These components work with the SoC to run the operating system and AI models. Your choices here directly affect the camera's speed and reliability. You can meet your performance needs while keeping the total cost for these parts under $10.

Sizing DDR SDRAM

Your camera needs Random Access Memory (RAM) to function. The SoC uses RAM to temporarily hold data for active tasks, like processing video from the sensor and running AI algorithms. A mid-range SoC requires enough RAM to avoid performance slowdowns.

For this project, you should choose between 512MB and 1GB of LPDDR4X RAM. This type of memory offers a good balance of speed and power efficiency. It provides enough capacity for the SoC to manage its tasks smoothly. You can source this component for about $4 to $6. This amount of RAM ensures your camera has the resources for real-time AI processing, giving you strong performance without a high cost.

Choosing Onboard Storage

Your AI camera also needs permanent storage. This holds the operating system, firmware, and your AI models. For a reliable and cost-effective solution, you should use an 8GB eMMC (embedded MultiMediaCard) module. An 8GB eMMC provides plenty of space and costs only $3 to $4.

Pro Tip: Local storage is key for an edge AI device. While cloud systems can use massive datasets, your camera must work with limited resources. Using smaller, curated datasets on local storage reduces computational needs and improves performance, which is perfect for a resource-constrained device.

You might consider a microSD card, but eMMC is a much better choice for this camera. The eMMC is soldered directly to the board, making it more durable and secure. It also delivers better random read/write performance, which is critical for running an operating system smoothly.

Market prices for 8GB eMMC modules can vary widely depending on the supplier. While some single units cost more, you can find them within your budget, especially when buying in larger quantities.

Choosing eMMC ensures your camera has dependable storage, which is essential for long-term performance. The SoC, sensor, and memory work together to create a powerful system.

CHOOSING PERIPHERALS AND POWER

You must select the right peripherals and power components to complete your camera. These parts support your SoC and sensor, enabling connectivity and ensuring stable operation. You can source these final components for under $20, keeping your total budget in check.

Connectivity Cost Analysis

Your AI camera needs to communicate with other devices. You will add Wi-Fi for wireless data transfer. Your HiSilicon SoC has interfaces like MIPI CSI-2 to connect the sensor and USB for other peripherals. The SoC processes the raw video from the sensor to perform advanced analytics.

For connectivity, you should choose a simple Wi-Fi 4 (802.11n) module. While high-performance Wi-Fi modules can cost over $170, you can find a basic module for just $5 to $7. This provides enough bandwidth for streaming video and sending analytics results for most surveillance applications. This choice is critical for maintaining the low cost of your camera and ensuring good performance. The SoC will manage the data flow, providing the intelligence for your security system.

Pro Tip: Your SoC can support other specialized sensors for advanced AI tasks. You could add thermal imaging or laser-ranging modules to your camera for more complex surveillance and security functions.

Power, PCB, and Thermal Design

The final hardware components are the printed circuit board (PCB), power management, and a cooling solution. Your powerful SoC requires a 4-layer PCB to function correctly.

• PCB Cost: Prototype PCBs can be expensive, sometimes over $50 per board. However, the cost drops significantly when you order in bulk, falling to just a few dollars per unit.
• Power Supply: You can use a simple Power Management IC (PMIC) and a standard 5V/2A power input. This is a cost-effective solution that provides stable power to the SoC and sensor.
• Thermal Management: Your SoC will generate heat while running AI models. You must add a small, low-cost heatsink to prevent overheating. This ensures consistent performance and protects the camera from damage.

These essential parts will cost you around $9 to $10 combined in production volumes. This careful selection ensures your camera has the foundation for reliable performance.
