| How to select the correct lens? | |||||||||||||||||
| Lens option | Refer to below picture and select the most suitable lens | ||||||||||||||||
| Remarks 1 | The larger the number of millimeters (mm) of the lens, the farther the view, the smaller the monitoring Angle at the same distance; On the other hand, the smaller the number of millimeters, the closer the view, the greater the monitoring Angle at the same distance. With mainstream 1/2.8 "CCD refer to the following figure: | ||||||||||||||||
| Focal length of lens (distortionless) | 1.4mm panorama | 1.8mm wide angle | 2.2mm | 2.4mm | 2.7mm | 2.8mm | 3.0mm | 3.5mm | 4.3mm | 4.2mm | 5.0mm | 6.0mm | 8.0mm | 12.0mm | 16mm | 25mm | 35mm |
| Monitoring angle | 220° | 160° | 140° | 130° | 120° | 110° | 95° | 90° | 75° | 70° | 60° | 55° | 45° | 30° | 20° | 15° | 10° |
| Monitoring distance | 0-2 meters | 0-2 meters | 0-3 meters | 0-3 meters | 0-4 meters | 0-4 meters | 0-5 meters | 0-5 meters | 0-6 meters | 0-6 meters | 0-8 meters | 0-10 meters | 5-20 meters | 5-35 meters | 10-50 meters | 20-80 meters | 30-100 meters |
| Remarks 2 | 1. For example, for a lens with a focal length of 2.4mm, its monitoring Angle is 130° and its effective monitoring distance is 0-3 meters, which means that the clearest effect is within 3 meters. | ||||||||||||||||
| 2. Similarly, for a 16mm focal length lens, its monitoring Angle is 20°, and the effective monitoring distance is 10-50 meters, that is to say, the clearest effect is within 50 meters. | |||||||||||||||||
