Buying Guide
Key considerations when selecting an SD card for surveillance cameras include endurance, capacity, and write stability. Endurance ratings indicate how many hours of continuous recording a card can sustain; higher is better for 24/7 monitoring. Capacity matters for longer retention periods; larger cards reduce the need for frequent offloads. Write speeds and class ratings (U3, V30) affect real-time recording quality, especially for 4K footage. Device compatibility is essential—ensure your camera supports the card’s format (microSDXC, SDXC) and speed class. Heat, moisture, and shock resistance are important for outdoor or unheated installations. For multi-camera systems, consider packs or multi-card options to simplify expansion and backups.
In summary, prioritize high-endurance cards such as SanDisk High Endurance lines for long-term security deployment, and pair with cards offering reliable write performance (U3/V30) to maintain smooth recording without data gaps. If you need more space, consider higher-capacity options or multi-pack sets, especially for systems with several cameras or extended retention policies.
