The CCTV Resolution vs Distance Simulator helps you compare how 2MP, 4MP, 6MP and 8MP cameras perform at different distances and lens focal lengths. Instantly see the difference between wide-angle overview coverage and zoom lenses for identification, recognition and detection — making it easier to choose the right camera for your site.

CCTV Resolution vs Distance Simulator (2MP vs 4MP vs 6MP vs 8MP)
Choosing the right CCTV camera isn’t just about megapixels — it’s about how many pixels actually land on the target at the distance you need.
The SecurityWholesalers CCTV Resolution vs Distance Simulator is a practical visual tool designed to show exactly how camera clarity changes depending on:
- Camera resolution (2MP, 4MP, 6MP, 8MP)
- Lens focal length (2.8mm wide vs 12mm zoom)
- Real-world distance from the camera to the subject
This is one of the most common points of confusion in CCTV planning:
a camera that looks excellent at 5–10 metres may become unusable for identification at 30–60 metres, even if it’s still recording in full HD.
Why Distance Matters in CCTV
As the subject moves further away, they occupy fewer pixels on the camera sensor. That means:
- Faces become harder to identify
- Number plates lose readable detail
- Footage becomes useful only for detection or overview
This simulator demonstrates that effect clearly, using realistic sensor-based modelling rather than artificial blur.
Lens Angle Makes a Huge Difference
A wide lens such as 2.8mm captures more area, making it ideal for general coverage.
A zoom lens such as 6mm or 12mm narrows the field of view, placing more pixels on the target at the same distance — improving recognition and identification.
The tool helps you understand why lens selection is just as important as megapixel count.
Identification vs Recognition vs Detection Rules
The simulator also references standard pixel density guidelines used by security professionals:
- Detection (~25 px/m): movement only
- Recognition (~125 px/m): familiar person
- Identification (~250 px/m): clear facial detail
This makes it easier to match camera specifications to your actual security goal.
Who This Tool Is For
This simulator is ideal for:
- Driveway and entrance camera planning
- Rural property and long-range coverage
- Retail shop surveillance layouts
- Warehouse perimeter monitoring
- Anyone comparing 2MP vs 4MP vs 8MP cameras
- NOTE THAT THIS TOOL IS VERY ROUGH- IT SHOULD ONLY SERVE AS A GUIDE ONLY
