How to Choose a Security Camera Lens
Selecting the right security camera lens is essential for achieving optimal image quality, object recognition accuracy, and monitoring coverage. Follow these steps to choose the best lens for your surveillance application.
Step 1: Determine Sensor Size
The lens image circle must match or exceed the camera sensor size. Using an incompatible lens may cause vignetting or image degradation.
- 1/4" sensor
- 1/3" sensor
- 1/2.8" sensor
- 1/1.8" sensor
Learn more in our Sensor Guide.
Step 2: Calculate the Required Field of View
Field of view (FOV) determines how much area a camera can monitor. Wider angles capture larger scenes, while narrower angles provide greater detail at longer distances.
Use our FOV Calculator to estimate the ideal focal length for your installation.
- Entrance monitoring
- Parking lot surveillance
- Perimeter security
- License plate recognition
Step 3: Select the Appropriate Focal Length
| Focal Length | Typical Use Case |
|---|---|
| 2.8mm | Wide-angle indoor monitoring |
| 4mm | General-purpose surveillance cameras |
| 6–8mm | Facial recognition and longer-distance monitoring |
| 12mm+ | License plate recognition and traffic monitoring |
Step 4: Consider Low-Light and IR Performance
Many surveillance systems operate day and night. IR-corrected lenses maintain focus under both visible and infrared light, ensuring reliable imaging in low-light environments.
Low distortion and high sensitivity are especially important for AI surveillance and facial recognition systems.
Step 5: Match the Lens to Your Application
- Smart City Monitoring – Wide-angle, high-resolution lenses
- Facial Recognition – Low-distortion lenses with high sharpness
- Traffic Monitoring – Telephoto lenses for long-distance capture
- AI Surveillance Cameras – IR-corrected lenses for 24/7 operation
