📋 目次
1What resolution should I look for in a 4K security camera?
4K resolution typically refers to 3840 x 2160 pixels, offering four times the clarity of 1080p HD. This is ideal for capturing fine details like license plates or facial features, but ensure your camera supports 4K at 30fps for smooth video without lag or motion blur.
2Do I need a camera with night vision, and what type is best?
Yes, for 24/7 coverage, look for infrared (IR) night vision with at least 30 meters of range. Some models use color night vision, which preserves color in low light but may have a shorter range. IR is more reliable for complete darkness but produces black-and-white footage.
3What’s the difference between wired and wireless 4K security cameras?
Wired cameras offer more stable performance, faster data transfer, and are harder to hack, but require drilling and cabling. Wireless models are easier to install and more flexible, but may suffer from interference or lag, especially in large homes with thick walls.
4How important is the field of view for a 4K security camera?
A wide field of view, typically 110-130 degrees, helps cover more area with fewer cameras. Narrower angles (less than 90 degrees) may require more units to monitor the same space, increasing cost and complexity. Look for adjustable lenses if your setup needs flexibility.
5What storage options are best for 4K security cameras?
Local storage via microSD cards (up to 256GB or more) is convenient for short-term use, but cloud storage offers remote access and backup. However, 4K video uses more data, so plan for at least 100GB per month of continuous recording. Hybrid systems offer the best of both worlds.
