• Desktop PC/Server: A dedicated desktop PC or server offers the most processing power and storage capacity, ideal for handling multiple high-resolution cameras.
• Important Considerations: The CPU on your dedicated device is important, as object detection is CPU intensive. RAM also plays a significant role.

Storage:

• Hard Drive (HDD) or Solid State Drive (SSD): Frigate stores video recordings on a local storage device. An HDD offers more storage capacity at a lower cost, while an SSD provides faster read/write speeds and improved performance.
• Storage Capacity: The required storage capacity depends on the number of cameras, resolution, frame rate, and retention period. Calculate the storage needs based on your specific requirements. Consider using a dedicated external hard drive for storing recordings.
• Network Attached Storage (NAS): A NAS device provides centralized storage for multiple devices on your network. Frigate can be configured to store recordings on a NAS.
• Recommendations: A 1TB or 2TB HDD is a good starting point for a typical home surveillance system. If you prioritize performance, consider using an SSD for the Frigate operating system and a separate HDD for recordings.

Networking:

• Ethernet Cable (Recommended): Wired connections provide greater stability and bandwidth compared to Wi-Fi.
• Wi-Fi Router: If using wireless cameras, ensure a strong and stable Wi-Fi signal in the camera’s location. Consider using a mesh Wi-Fi system for better coverage.
• Power over Ethernet (PoE) Switch (Optional): PoE switches provide power and network connectivity to cameras over a single Ethernet cable, simplifying installation.
