Security Camera Resolution Guide: 1080p, 2K & 4K Explained

When shopping for a security camera, one of the first specifications you’ll notice is the camera resolution. You’ll often see terms like 1080p, 2K, 3MP, 4MP, 5MP, and 4K, but what do they actually mean? More importantly, which resolution is best for your home or business?

4K	8MP	Ultra HD	Large properties & commercial surveillance
