Megapixels don't tell you whether you'll identify a face at the distance you need — that is a lens and sensor job. This guide explains 4MP versus 5MP versus 4K in practical terms: storage cost per camera, low-light behavior, and what resolution you realistically need for your camera-to-subject distances.
What each resolution resolves
4MP identifies a face at roughly 10 to 12 metres, 5MP stretches that slightly, and 4K buys useful long-range detail plus wider digital zoom.
A top pick in this category is the Uniview UAC-T125-APF28LM 5MP LightHunter PoC Fixed IR Turret Analog Camera, available from $199.00. This model delivers the performance and reliability that Florida installers depend on for consistent, high-quality video surveillance.
The storage cost of more pixels
Doubling the pixel count roughly doubles the bitrate, so a 4K upgrade on a 32-camera system can require a second hard drive for the same retention.

Choosing per camera, not per site
Specify 4MP for general coverage, 5MP for entries, and 4K only where long-range identification or wide-area overview is genuinely required.

Frequently asked questions
Is 4K always better than 4MP?
No. Without enough light and a suitable lens, a 4K camera can look noisier than a 4MP model at night while costing more storage.
How much storage does a 4K camera need?
Plan on roughly 2 to 4 GB per camera per day at continuous 4K, then use a storage calculator to confirm your retention target.
