Analog Camera Lens Selection Guide: Choosing the Right Lens for Better CCTV Performance

• Narrow viewing angles
• Greater image detail
• Better long-distance monitoring
• Suitable for parking lots, gates, and warehouses

Before selecting any analog CCTV camera, identify what needs to be monitored rather than simply choosing the widest available lens.

Fixed Lens vs. Varifocal Lens

Most surveillance cameras use either fixed or varifocal lenses.

Fixed Lens

A fixed lens offers a permanent viewing angle. It is easy to install, requires minimal adjustments, and is generally more affordable.

Best applications include:

• Small offices
• Residential rooms
• Reception areas
• Indoor hallways

Varifocal Lens

A varifocal lens allows installers to manually adjust the zoom level and viewing angle after installation.

It is ideal for:

• Parking areas
• Building entrances
• Warehouses
• Commercial properties
• Large outdoor spaces
