परिचय: Is 4K Worth It?
4K security cameras deliver four times as many pixels as 1080p. That means you can read license plates from 50 feet away, identify faces without doubt, and recognize fine details that remain blurry at lower resolutions.
However: 4K requires more bandwidth, more storage, and better lighting. Not every situation calls for 4K. We tested the best 4K cameras for various use cases.

4K Storage and Bandwidth Calculator
With 4K, you should calculate storage requirements before purchasing:
- 1080p: ~2-4 GB per day per camera (24/7)
- 2K: ~5-8 GB per day per camera (24/7)
- 4K: ~15-25 GB per day per camera (24/7)
A 4TB hard drive stores about 160-270 days of 4K footage – per camera. Plan accordingly.
Bandwidth: 4K requires about 8-12 Mbps upload per camera. Make sure your network supports it.
हमारा फैसला
The Amcrest IP8M-2496B is the best 4K camera for most applications. For ultra-wide angle coverage, we recommend the Reolink RLC-822A, and for tighter budgets, the Reolink RLC-520A.
