Dive into the world of imaging with our latest article comparing the Night Stalker 4K and DS35 (2K) cameras! Discover how each resolution excels in clarity and detail capture, and see which one truly stands out in various scenarios. Whether you're a photography enthusiast or a seasoned pro, understanding the differences between these sensors is key to elevating your visuals.

Resolutions

1. Definition

Resolution refers to the number of pixels in an image or display, typically expressed as width x height. It directly impacts image clarity and detail. Higher resolution means more pixels, resulting in finer and more detailed images.

2. Definitions of 2K and 4K Resolution

· 2K Resolution: Around 2,000 horizontal pixels, typically referring to 1920x1080, 2048x1080 (rarely used), or 2560x1440.

· 4K Resolution: Around 4,000 horizontal pixels, specifically 3840x2160, delivering higher clarity and richer details.

Note: The 2K and 4K designations for sensors, displays, photos, and videos all refer to pixel count.

3. Detector Resolution Comparison

Feature	DS35 (2K)	Night Stalker 4K
Resolution	2560x1440	3840x2160
Image Quality	Lacking in detail and clarity.	Greater detail

Pixel Size

1. Definition

Pixel size refers to the physical size of a single pixel in an image sensor, typically measured in micrometers (μm). It affects the sensor's light sensitivity and image quality.

2. Difference in the size of 2.9μm & 2μm pixel

Pixel size	2.9μm	2μm
Light Sensitivity	Higher, ideal for low-light conditions	Lower, suited for well-lit conditions
Image Quality	Less noise, higher brightness	Potentially more noise, lower brightness

3. Imaging Comparison：DS35 vs. Night Stalker 4K

	DS35	Night Stalker 4K
Resolution	2560*1440	3840*2160
μm Pixel Size (μm)	2.9	2
Magnification	4/5.6	4/5.6/8
Digital Zoom	2	2/3/4

Summary

· DS35 (2K): Features 2K resolution (2560x1440) and a 2.9μm pixel sensor, excelling in low-light environments with stable image quality.

· Night Stalker 4K: Features 4K resolution (3840x2160) and a 2μm pixel sensor, offering higher resolution and detail, though it may underperform in low-light conditions compared to the DS35.
