CCTV camera lens guide
If you’re new to security cameras you may think all lenses all the same… but they’re not. This is why choosing the right one is an important consideration, as this impacts your security footage.
There are actually a wide variety of lenses which produce different scenes, known as field of view. CCTV camera lenses are designed to address specific surveillance needs.
Before we delve into your different choices, let’s go back to basics on field of view…
Making sense of the Axis camera naming convention
As the manufacturer of the first network camera, Axis have had a long time to get their naming convention right.
With a wide product range, they’ve adapted their naming for different sets of devices. For example, covert cameras numbering has a different meaning to their full-sized cousins.
Let’s dive into what those letters and numbers mean…
What’s the difference between varifocal and fixed lens CCTV?
One of the most frequent questions we get asked is the reason some cameras are priced differently to others. There’s often a variety of reasons, but one of the main culprits is the lens.
In short, fixed lens cameras give a specific field of view, while the viewing angle of a varifocal is set during installation. The moving parts and lens adjustment required for varifocals increases the price of a camera.
Though, of course, there’s a little more to it than that.

Lightfinder 2.0 – what is it and what difference does it make?
In May this year Axis launched some new cameras which contained Lightfinder 2.0. This was slipped in quietly as a feature, but nevertheless intrigued us. What exactly is it?
Lightfinder technology is geared around providing full colour HD video, even in near darkness. The claims are that Lightfinder 2.0 provides:
- More realistic colours
- Clearer visibility of dark areas
- More details captured
- Sharper images
- Less motion blur
As most cameras now have some way of providing usable night images how impressive is Lightfinder 2.0 in this context?
Axis new chipset – a game changer?
Every 2 years or so, Axis releases a new chip into their cameras, the latest one is ARTPEC-7. While that isn’t newsworthy by itself, what it enables the cameras to do is.

This model is among the first to feature the new ARTPEC-7 chipset and Lightfinder 2.0 to boost low light performance.
Without further ado, let’s find out a bit more about these new models.
