Top Things to Consider

When it comes to security cameras, understanding the differences between 4K, 1440p, 1080p, and 720p resolutions in terms of image quality, field of view, storage consumption, compatibility, cost, and future-proofing is critical to choosing the most suitable resolution.

1. Image Quality: The higher the resolution, the better the image quality and the more vivid the details. 4K and 1440p resolutions provide superior image quality with enhanced clarity and finer details compared to the lower 1080p and 720p resolutions. For instance, if capturing license plate numbers is your objective, 4K and 1440p cameras effectively recognize the numbers from a distance, while the chances are slimmer for 1080p and 720p cameras.
2. Field of View: Megapixel security cameras often feature wider-angle lenses, offering a broader field of view. 4K cameras have a wider field of view than 1440p, 1080p, and 720p surveillance cameras, enabling them to monitor large areas in a single shot, leaving no blind spots and reducing the number of required cameras.
3. Bandwidth & Storage Consumption: Higher resolution cameras require more bandwidth and storage consumption, but H.265 high-efficiency coding in 4K cameras can reduce bandwidth utilization and storage consumption by up to 50% without compromising image quality.
