Have you ever been perplexed when choosing a lens for your security camera? The focal length of the lens, measured in millimeters, directly affects the field of view and the range of your security system. This could make a significant difference depending on the specific surveillance needs of your home or business.
Let’s break it down:
• A 2.8mm lens provides a field of view of approximately 80-90 degrees, with an outdoor infrared distance of about 3 meters and an indoor infrared distance of up to 5 meters.
• A 3.6mm lens offers a field of view of about 70-80 degrees, with both outdoor and indoor infrared distances ranging from 5 to 10 meters.
• A 6mm lens has a 50 degree field of view, with an outdoor and indoor infrared distance of 5-10 and 10-15 meters respectively.
• An 8mm lens shows a 38 degree field of view, and both the outdoor and indoor infrared distance is between 10 and 15 meters.
• A 12mm lens provides a narrower 26 degree field of view, with an outdoor infrared distance of 10-20 meters and an indoor one ranging from 20-30 meters.
• A 16mm lens offers a field of view of 20 degrees, with the outdoor and indoor infrared distance from 20-30 and 30-40 meters respectively.
Lastly, a 25mm lens delivers a 12 degree field of view with an outdoor infrared distance of 30-40 meters and an indoor one reaching up to 40-50 meters.
Choosing the right lens is important as some consumers may require a broader field of view, while others may need a longer infrared distance for larger areas. I hope this information helps in making your next security camera lens choice a more informed one.
Remember, the right lens for your surveillance needs can make all the difference. Stay secure!
