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

Varifocal lenses offer greater flexibility, especially when camera placement may change over time.

Choosing the Right Viewing Angle

Every surveillance area requires a different field of view.

Wide-angle lenses cover larger spaces but capture fewer fine details.

Narrow-angle lenses capture greater detail but monitor smaller areas.

For example:

• Living rooms benefit from wider viewing angles.
• Cash counters require more detailed close-up monitoring.
• Gates need balanced coverage with clear identification.
• Corridors typically require medium viewing angles.

Choosing the correct balance between coverage and detail is essential for effective surveillance.

Indoor Lens Selection

Indoor environments generally require wider viewing angles because monitoring distances are shorter.

Recommended areas include:

• Homes
• Offices
• Schools
• Shops
• Reception desks
• Hotel lobbies
