CS-Mount Lenses Focal Length Compatibility Differences

1. Short Focal Length (2.8mm-5mm): Wide-Angle Coverage

The core advantage of short focal length lenses is their ultra-wide field of view, achieving wide coverage with a smaller installation space, making them the first choice for indoor wide-area monitoring and close-range scenarios.

• Suitable Scenarios: Smart home security (living room, entryway), access control monitoring, elevator cars, small shop interiors, underground parking garage entrances, and other enclosed/semi-enclosed spaces requiring panoramic coverage.
• Key Features: Field of view up to 90°-131°, no blind spots at close range; large depth of field, clearly displaying both near and distant objects; some models have optimized edge distortion control to avoid image stretching and distortion.
• Applicable Devices: Compact devices such as small home cameras, access control systems, and elevator cameras; compatible with 1/2.7″-1/1.8″ small to medium-sized sensors.
• Precautions: Limited ability to capture details at long distances; unsuitable for scenarios requiring the identification of distant objects (e.g., license plates, close-ups of faces).

2. Mid-range focal length (8mm-16mm): Balanced and adaptable

The mid-range focal length is a “universal focal length” that balances field of view and detail capture. It offers a moderate field of view, ensuring image clarity at medium distances while covering a certain area, making it suitable for the widest range of scenarios.

• Suitable scenarios: Industrial automation inspection (production line parts inspection), community corridor/courtyard monitoring, medium-sized shop cash register monitoring, office security, medical imaging equipment-assisted imaging, and other scenarios requiring both wide coverage and detail.
• Key features: Field of view approximately 30°-60°, low imaging distortion rate (typically ≤1%), high image fidelity; medium depth of field, enabling precise focusing on target areas, suitable for scenarios requiring size measurement or detail recognition.
• Applicable Equipment: Industrial inspection cameras, high-definition surveillance PTZ cameras (fixed focal length), portable medical imaging equipment, commercial security cameras, etc., compatible with 1/1.8″-2/3″ medium to large sensors.
• Notes: Coverage is limited in very large areas; multiple cameras or zoom lenses are required.

3. Telephoto (12mm-50mm+): Detail-Focusing

The core value of telephoto lenses is long-distance detail capture. With a narrow field of view, they can magnify and clearly present distant objects, making them a core choice for long-distance monitoring and precise identification scenarios.

• Suitable Scenarios: Intelligent transportation systems (road license plate recognition), perimeter monitoring of large parks, long-distance monitoring of agricultural pests and diseases, port/airport security, high-precision industrial measurement, and other scenarios requiring long-distance focusing.
• Key Features: Field of view only 8°-33°; zoom and telephoto models allow for flexible focus distance adjustment; some high-end models are equipped with a P-Iris precision aperture, maintaining image stability in varying lighting conditions; shallow depth of field accurately highlights target objects and suppresses background interference.
• Applicable Equipment: Traffic monitoring cameras, long-zoom security PTZ cameras, high-precision industrial measuring cameras, agricultural remote sensing monitoring equipment, etc.; compatible with 2/3″ and larger sensors to ensure image quality.
• Precautions: Requires high installation stability; even slight shaking will cause image blurring; narrow field of view and small coverage area, usually requiring use with a wide-angle lens; some telephoto models are relatively large, requiring sufficient installation space.

CS-Mount Lenses Target Audience

CS-Mount Lenses are not just for professional industrial and security personnel. What truly makes them appealing is their balanced combination of professional performance, scenario adaptability, and high cost-effectiveness. They offer corresponding application scenarios for different user groups. Here’s a table to help you decide if you’re one of them:

FAQs

How to choose CS-Mount Lenses (focal length) for different daily scenarios?

Focal length selection depends on monitoring range and detail needs. Choose 2.8-8mm short/zoom lenses for wide coverage (e.g., smart home, small shops); 8-16mm medium lenses for balanced range and detail (e.g., community, office monitoring); 12-50mm telephoto lenses for long-distance recognition (e.g., license plates, park perimeters).

Why do some CS-Mount Lenses emphasize “infrared correction”?

Infrared correction solves color/clarity issues in day-night monitoring. Ordinary lenses blur and distort colors under nighttime IR lighting, while corrected lenses (via special coatings) handle both visible and IR light for true daytime colors and clear night vision. It’s a must for 24/7 scenarios (e.g., home security, roads) and optional for daytime-only use (e.g., office monitoring).

What key parameters matter for CS-Mount Lenses in home scenarios?

Prioritize compatibility and practicality. 8MP resolution suffices for face/object recognition (no need for excessive pixels); F1.6+ large aperture enhances low-light intake for clear night vision; 20-100g lightweight design fits small home cameras; low power consumption enables non-stop operation; infrared correction is recommended for seamless day-night use.

Does CS-Mount Lens installation require specialized tools?

No professional tools are needed. Most consumer/commercial models have a threaded design—align and hand-tighten with the camera; fine-tune focus/aperture per instructions. Maintenance: Avoid touching lens surfaces; wipe dust gently with a professional cloth. For outdoor use, check waterproof/dustproof seals. If images blur over time, readjust the focus ring; inspect for lens wear/dust if issues persist.
