Manual Aperture 6-60mm CS Mount CCTV Lens with F1.6 Maximum Aperture for Security Camera Systems

Designed for surveillance and monitoring applications, this manual aperture CS mount camera lens provides optical versatility through its 6-60mm focal length range. The lens covers angular fields of view from 44° at its widest setting to 4.58° at maximum telephoto, allowing operators to frame both expansive areas and distant details without changing equipment. With a maximum aperture of F1.6, it maintains light-gathering capability in various lighting conditions, while its manual focus and aperture controls offer precise adjustment for specific monitoring requirements. The lens is engineered for 1/3" image sensors, maintaining compatibility with numerous CCTV camera bodies commonly used in security installations.

Optical Specifications and Performance

The lens delivers 10x optical versatility through its 6-60mm focal range, translating to significant framing flexibility for surveillance operators. This range eliminates the need for multiple fixed-focal-length lenses in many applications, providing both wide-area monitoring and detailed observation capability.

Focal Length and Field of View

At its 6mm setting, the lens provides a 44° angular field of view suitable for monitoring open areas, entranceways, or large rooms. When adjusted to 60mm, the field narrows to 4.58°, allowing operators to focus on specific details, facial recognition, or license plate reading at greater distances. The continuous adjustment between these extremes enables operators to frame scenes precisely according to changing security needs without physical camera repositioning.

Aperture and Low-Light Performance

The F1.6 maximum aperture represents a relatively wide opening that admits more light than typical security lenses with smaller apertures. This characteristic supports clearer imaging in dimly lit environments where supplementary lighting may be limited or undesirable. The manual aperture control allows operators to balance depth of field and exposure according to specific scene requirements, though automated exposure systems in compatible cameras will typically manage this adjustment in practice.

Minimum Focus Distance

With a 0.3 metre minimum object distance, the lens can focus on subjects relatively close to the camera position. This capability supports applications requiring detailed inspection of nearby objects or documents, though most security installations will utilise greater working distances. The manual focus mechanism enables precise adjustment throughout the entire focus range.

Physical Construction and Compatibility

The lens features a compact form factor designed for integration with various CCTV camera systems. Its construction prioritises functional durability while maintaining the optical precision required for surveillance applications.

Mount Interface and Sensor Format

The CS mount interface represents an industry-standard connection method for CCTV lenses, ensuring compatibility with numerous security camera bodies. This mount type typically provides secure mechanical attachment and proper flange focal distance for accurate focusing. The lens is designed specifically for 1/3" image sensors, matching the format commonly found in surveillance cameras and ensuring the entire image circle is properly utilised without vignetting.

Dimensions and Weight

Measuring 37mm in diameter with a 68.7mm length and 34mm height, the lens maintains a compact profile suitable for discreet installations or systems with spatial constraints. At 118 grams, it adds minimal weight to camera assemblies, supporting mounting on various brackets and fixtures without excessive load. These dimensions represent the lens body measurements excluding any protruding controls or mounting hardware.

Manual Control Mechanism

Both aperture and focus are manually controlled through dedicated rings on the lens barrel. This design provides tactile feedback and precise adjustment capability, though it requires initial setup and occasional readjustment rather than automated operation. The manual controls are particularly valuable in fixed installations where lighting conditions and focus distances remain relatively constant once optimised.

Application Scenarios and Practical Use

The lens's specifications support various surveillance and monitoring applications where optical versatility and manual control are advantageous. Its combination of wide to telephoto capability in a single unit simplifies system design and reduces equipment requirements.

Commercial and Institutional Security

In retail environments, the lens can monitor both wide store areas at 6mm and specific high-value merchandise or transaction points at longer focal lengths. Educational institutions benefit from the ability to frame expansive corridors or playgrounds while retaining the option to focus on specific access points or gathering areas. Office buildings can utilise the lens for both general monitoring and detailed observation of reception areas or secure zones.

Industrial and Perimeter Monitoring

Manufacturing facilities can employ the lens for both overall process monitoring and detailed equipment inspection. The 0.3m minimum focus distance supports close-up examination of components or quality control checks when cameras are positioned appropriately. Perimeter security applications benefit from the telephoto capability for identifying individuals or vehicles at distance, while retaining wide-angle coverage for general area surveillance.

Residential and Small Business Security

For residential installations, the lens provides comprehensive coverage of properties without requiring multiple cameras or frequent adjustments. Small businesses appreciate the ability to monitor both customer areas and transaction points with a single camera system. The manual controls allow property owners to optimise the lens for their specific layout and lighting conditions during initial setup.
