Yes. The Goobuy 4.5–148.5mm 33X lens provides stable long-range zoom and precise motorized focus, making it ideal for PTZ domes and high-speed IP cameras.

 

2. Can Goobuy 33X motorized zoom lens be used in LPR/ANPR highway systems?

Absolutely. The narrow 2.36° horizontal FOV at telephoto allows accurate long-distance license plate capture on highways and bridges.

 

3. What sensor size is this lens optimized for?

It is engineered for 1/2.7’’ 2MP/4MP sensors and supports 2688×1520 resolution with excellent clarity.

 

4. Does this lens support day/night and IR-assisted monitoring?

Yes. The lens is IR-corrected and works well with IR illumination for night surveillance.

 

5. What type of motor is used for zoom and focus?

It uses a stepper motor for zoom and a step motor for focus, enabling smooth and stable long-range adjustments.

 

6. What is the minimum object distance (MOD)?

MOD is 2m at wide angle and 30m–∞ at telephoto, suitable for long-range tower and perimeter monitoring.

 

7: "What is the aperture at full telephoto (148.5mm)?"

The aperture ramps from F1.4 (Wide) to F4.2 (Tele). This ensures good light intake at the wide end, while providing sufficient depth of field at the telephoto end.

 

8,  "What type of motors are used for Zoom and Focus?"

The lens uses precision Stepper Motors (2-phase) for both Zoom and Focus elements, allowing for accurate digital preset positions in PTZ systems.
