How to Choose a CCTV Lens – From Resolution to Viewing Angle

• 1. Resolution: Prioritize 1080P and above high-definition specifications. 4K image quality is suitable for scenarios requiring high detail (such as shop cash registers).
• 2. Viewing Angle Coverage: A true panoramic lens should achieve a 360° horizontal viewing angle, avoiding “pseudo-panoramic” lenses (actual viewing angle <180°).
• 3. Night Vision Capability: Supports infrared night vision or starlight night vision. A night vision distance of ≥10 meters is more practical. Image clarity is crucial in low-light environments.

FAQs

Why is the resolution of a CCTV lens important?

Resolution directly affects the clarity of the surveillance footage. High-resolution lenses (such as 1080P and above) can capture more details, suitable for scenes requiring precise identification, such as faces, license plates, etc. Especially in shops and important areas, choosing ultra-high resolution lenses such as 48 megapixels ensures that key details remain clearly visible even after magnification.

What is a panoramic CCTV lens, and what are its advantages?

Panoramic CCTV lenses typically feature a wide-angle or fisheye design, covering a larger field of view. A horizontal viewing angle of 220° or higher enables monitoring without blind spots, reducing blind areas. This is especially important for large spaces (such as shop lobbies or warehouses), avoiding the complexity and cost of stitching together multiple cameras.

How does night vision affect surveillance performance?

Night vision allows surveillance equipment to maintain good image quality in low-light environments. Lenses supporting infrared night vision or starlight night vision can capture clear images in complete darkness. Choosing a lens with a night vision range greater than 10 meters provides more reliable monitoring at night, ensuring security without time constraints.

What special features do outdoor CCTV lenses need?

Outdoor CCTV lenses need to be waterproof, dustproof, and have a wide operating temperature range. An IP69K protection rating ensures the device operates normally in harsh weather conditions (such as heavy rain and sandstorms). Simultaneously, the lens must be able to withstand extreme temperature changes (e.g., -40°C to +85°C) to guarantee stable monitoring around the clock.
