Security cameras come in all shapes and sizes, each with its own set of advantages. One popular style is the bullet camera – known for its tough, vandal-resistant cylindrical body that houses the lens, making it ideal for outdoor installation.

However, regular bullet cameras have a fixed focal length, limiting the field of view once mounted. This is where varifocal bullet cameras come in, combining the flexibility of adjustable lenses with the durability of bullet housings.

The Versatility of Varifocal Lenses

Varifocal lenses allow photographers to change the focal length, modifying the camera's field of view and zoom capabilities. This enables adjusting and optimizing the framing of a shot, even after a camera has been installed in a fixed position. Varifocal lenses provide either manual or motorized remote control over focal length adjustments. This brings a new level of versatility to tough and dependable bullet cameras.

Key Benefits of Varifocal Bullet Cams

Varifocal bullet cameras retain all the advantages of standard bullet cams while removing the restrictions of permanent focus and zoom. Instead, security teams can tweak the lens focus and zoom to capture just what they need. Benefits include:

  • Adjusting the field of view without moving the camera
  • Zooming in to see important details from afar
  • Fixing improper initial focus without physical access
  • Meeting changing security needs without added cameras
  • Built-in versatility for evolving spaces and requirements

Choosing and Adjusting Varifocal Bullet Lenses

Varifocal bullet cams are available with a range of motorized and manual zoom lenses. Wider focal ranges allow more versatility. For example, a 2.8–12mm varifocal lens provides far more ability to widen or tighten the shot than a 3–9mm lens. Higher-quality lenses also provide better optical performance.

For manual lenses, adjust zoom and focus by turning rings on the camera housing. Motorized lenses allow remote control of adjustments via software from a central monitoring location. This enables fine-tuning the shot without physical access to cameras.

Top Uses for Varifocal Bullet Cams

Installing varifocal bullet cams allows security teams to optimize the camera framing for:

  • Large areas: Zoom in on specific zones for more detail
  • Changing layouts: Alter focus as needs evolve
  • Point-of-sale: Isolate key areas without moving the camera
  • Parking lots: License plate recognition from a distance
  • Building perimeters: Adjust to cover access points without blindspots

For example, utilizing a 4MP Hikvision varifocal bullet camera allows capturing a large area while also having the flexibility to zoom in and identify specific people or objects more clearly. Similarly, a Hikvision 5MP varifocal bullet camera can provide detailed megapixel video quality with the ability to tweak the field of view for evolving needs.

The Bottom Line

Varifocal bullet cameras provide the perfect combination of bullet cam toughness and adjustable lens versatility. There's no need to choose between durable construction and flexible zooming capability – you get both with varifocal bullet cams.
