Which Camera Will You Choose?
When it comes to protecting your home or business, security cameras are one of the most powerful tools available. But with so many options—varifocal, dome, turret, bullet, PTZ, panoramic and more—it can be overwhelming to figure out what’s right for your space.
Here’s a breakdown of the 6 most common security cameras, what they do, and how to choose the best system for your needs.
What Is a Varifocal Security Camera?
Varifocal – A varifocal camera is a type of security camera with an adjustable lens that allows you to manually or remotely zoom in and out without losing focus. Unlike fixed-lens cameras, varifocal models give you flexibility in how much area you want to cover and the level of detail you need.
Key Features of Varifocal Cameras
🔭 Adjustable Zoom and Focus
- Zoom range is usually something like 2.8mm–12mm or wider.
- Zoom in for close-up detail (like a face or license plate).
- Zoom out for a wider field of view (like a parking lot or backyard).
🎯 Better Scene Customization
- Ideal for areas where the camera’s position may change or where you want to fine-tune your coverage later.
- Great for entrances, gates, loading docks, or long driveways.
🌙 Infrared Night Vision
- Most varifocal cameras include IR LEDs for clear images in low light or total darkness.
💾 HD or 4K Resolution
- Often come in high-definition (1080p, 4MP, 5MP, or even 4K) to ensure you don’t lose clarity when zooming.
🔒 Weatherproof & Vandal-Resistant Options
- Available in dome or bullet housings for indoor or outdoor use.
- Many models are IP66/IP67 rated for harsh weather and built with metal casings to prevent tampering.
🔌 Wired (PoE) or Hybrid
- Typically used in professional-grade systems, often powered via Ethernet (PoE) for both video and power.
What Are Varifocal Cameras Used For?
- Commercial entrances – zoom in on visitors or license plates.
- Warehouses & loading docks – adjust view as your layout changes.
- Driveways or alleyways – monitor a narrow, long path.
- Retail stores – focus in on a register or merchandise.
- Ranches & acreage – get detailed views of gates or barn entrances.
✅ Why Choose a Varifocal Camera?
If you need flexibility, precision, and long-term control over your surveillance view, varifocal cameras are a smart choice. They’re more versatile than fixed cameras and give you the power to adapt your system as your security needs evolve
