When investing in a CCTV camera, most buyers focus on resolution—HD, Full HD, or 4K. However, the lens is equally critical. The right CCTV lens determines field of view, clarity, depth, and identification accuracy. A wrong lens can result in blind spots, blurred faces, or wasted storage. At GoLive eTechnologies India Private Limited, we help customers choose not just cameras, but complete surveillance and smart infrastructure solutions—from Evota PTZ cameras, Evota 4K camera systems, to interactive digital boards and online class studio setups for schools, offices, and institutions across India. This guide explains how to choose the perfect CCTV lens based on your use case, budget, and location.

1. Understanding CCTV Lens Types

A fixed lens offers a constant focal length, commonly 2.8mm, 3.6mm, or 6mm.

Best for:

• Homes & small offices

• Corridors, classrooms, entry points

Benefits:

• Cost-effective

• Low maintenance

• Ideal for budget CCTV setups

GoLive eTechnologies offers fixed-lens CCTV solutions often paired with Evota camera price ranges that suit Indian schools and SMEs.

Varifocal Lens Cameras

A varifocal lens allows manual or motorized zoom adjustment, typically 2.8–12mm.

Best for:

• Retail shops

• Parking areas

• Warehouses

Advantages:

• Reduces need for multiple cameras

Many customers combine varifocal CCTV with Evota digital board or interactive panel board installations for unified smart infrastructure.

PTZ Camera Lenses (Pan-Tilt-Zoom)

PTZ cameras come with motorized optical zoom (10x, 20x or more).

3. Indoor vs Outdoor Lens Selection

Indoor CCTV Lens
