IP cameras, much like any other product on the market, have their intricacies. For example, when choosing an IP camera, you not only look at the maximum supported resolution of the product but you also have to look at the other things as well.
Not all IP cameras are suitable for everybody as every IP camera is different to suit the individual needs of the consumer.
In today’s article, I want to talk about the lens of the IP camera. How exactly do you choose the right lens for you?
Well, I am going to talk about the basics of the lens so that you can gauge which one you want that suits your very needs.
Now, when looking at IP cameras, you might see that they have lenses that have different sizes (denoted by mm). It is quite easy to discern which focal length you need for your needs.
The idea is this: if you want a wider viewing angle, select the lens with the lower number (like below 8). If you want a narrower angle but can zoom in on far places, then choose a lens with 12mm and above.
In most cases, you want to have an IP camera that has a 4mm to 8mm lens because this provides you with a lot of coverage area.
Do remember that these lenses do not have a lot of zooming capabilities compared to other focal lens, so that is something to keep in mind.
Another thing you want to consider when looking at the lens of the IP camera is the approximate field of view.
Each size of the lens will have different fields of view. As previously mentioned, the smaller the lens, the wider the coverage area.
For example, if your lens has an 8mm focal length, it can approximately cover 40-degree of an area. In other words, it has a 40-degree field of view.
Another example would be a lens with a focal length of 25mm. This type of lens will have a 12.5-degree angle coverage which, for the most part, is suitable if you want to have a lens that can zoom in on specific places.
And lastly, if your budget permits it, get a varifocal lens. Varifocal or otherwise known as the Variable Focus lens will adjust itself depending on your needs. This can be done using the IP camera’s video management software.
While this is a great thing, IP cameras that have a varifocal lens are much more expensive than their fixed focal length lens counterparts.
Now that you know the different IP Camera lens terminologies and what they mean, the next thing you should do now is think about what you need the IP camera for?
Do you want the IP camera to do surveillance work at a specific area? Or do you want an IP camera that can zoom in if needed?
That all depends on you. At least now, you’re equipped with the right knowledge so that you can make an educated purchase.
