Field Of Vision
Both 2.8mm and 3.6mm are very similar in most cases. But their biggest difference lies in the field of vision of both lenses.
2.8 mm Lens
The 2.8mm lens has a very larger field of view compared to 3.6mm. Its field of view is approximately 110 degrees. Which makes it a very common option for static camera surveillance. Even with only one sensor, it can cover a large area.
It’s great for monitoring the overall view. However, it can’t capture any detailed image or data if it’s far away. Like- car number plates.
3.6 mm Lens
The 3.6mm lens produces a scene that is identical to the 2.8mm lens. But they show more detail at a greater distance. The most noticeable change is the narrower field of vision. This gives the impression that objects are much closer to the camera. Its field of view is approximately 78 degrees.
This is why 3.6mm is also very useful when it comes to detection and recognition.
Both the lenses are considered wide-angle. Yet they differ from one another when it comes to distance coverage.
2.8 mm Lens
The 2.8 mm lens covers a total distance of 1.5 meters. Which is half less than 3.6mm. But that doesn’t mean it doesn’t provide more coverage. In fact, a 2.8 mm lens provides more coverage as it has a larger view of angle.
3.6 mm Lens
The 3.6 mm lens covers a total distance of 3 meters. Its wide distance coverage along with its narrower field of view makes it perfect for grabbing details.
Placement of Camera
The placement of your CCTV camera is very crucial. It makes sure that it works with the highest efficiency and effectiveness.
2.8 mm Lens
When it comes to the indoors, the 2.8mm lens is a very common option amongst most CCTV users. In order to monitor an entire room, you’ll only need one camera mounted at the corner. So it’s great for overview shots.
3.6 mm Lens
Due to their field of vision, they’re frequently used in areas where detail is important. It’s usually placed in front of doors. It’s also useful when you need a narrower view to avoid inspecting unnecessary scenery.
Thus, they’re placed conspicuously around these areas.
Depending on their attributes both of the lenses are used for different purposes. This ensures the best results.
2.8 mm Lens
It’s perfect for covering the top of your house. Or to get a bird’s-eye view of your whole backyard. You can keep an eye on your kids or pets while you’re in the kitchen preparing dinner.
They’re also useful for outdoor places like train station platforms.
3.6 mm lens
A 3.6 mm lens is usually used for surveillance in front of doors. Especially to catch and identify someone stealing your packages or attempting to break-in.
In that case, 3.6mm is the perfect choice for security concerns.
Which Lens Should You Go For?
There is no one fixed choice between both the lenses.
The reason being, everyone’s requirements are different. Your lens preference depends on the placement of the camera, coverage angle, etc. For example – your front porch and someone else’s front porch aren’t the same. This is why we cannot give you an absolute answer.
However, we can help you understand which is best suited based on your requirements and landscape.
If you’re looking for a lens to overlook a wide area without any details, go for a 2.8mm lens. This kind of lens is perfect for indoors, backyard coverage, etc.
