How to Choose the Right CCTV Lenses in 2026

Key Factors to Consider

• Sensor size matching
  • Lens image format ≥ camera sensor size to avoid vignetting and dark edges.
• Mount type
  • C‑mount: industrial, traffic, machine vision
  • M12/S‑mount: compact PCB, mini cameras, home security
• Focal length & FOV
  • Short focal = wide view (rooms, entrances)
  • Long focal = narrow view (details, distance)
  • Varifocal = adjustable for multi‑purpose
• Aperture (F‑number)
  • F1.0–F1.4: best night vision
  • F2.0–F2.8: balanced day/night
  • Fixed iris: simple, cost‑effective
  • Auto iris: stable in changing light
• IR correction
  • Must for 24/7 day/night surveillance
• Distortion
  • Low distortion (<1%) for recognition tasks
• Resolution
  • Match lens MP to camera MP for full clarity
