This blog details why SD cards are essential for security cameras, provides key tips on choosing the right one (speed class, endurance, compatibility, protection, anti-counterfeiting), and recommends optimal SD card sizes for different recording scenarios, helping you select a reliable storage solution.
SD cards and SIM cards, though similar in size, serve distinct roles—especially in surveillance cameras. SD cards are removable storage devices that save video footage locally, ideal for offline backup or avoiding cloud fees. SIM cards, tiny chips tied to cellular networks, enable cameras to connect wirelessly in Wi-Fi-free areas, supporting live streaming and alerts via mobile data. They can work together for both local storage and remote access.
