Likely, the first thing you will realize when researching CCTV installation for your Southern Colorado business is that there are options galore regarding the type of security camera lenses available. Choosing the right lens for the right application can make all the difference in capturing clear, detailed images that can help protect your business from theft, vandalism, and other security threats.

In this guide, we’ll take a closer look at several types of security camera lenses and how to choose the right one for your Colorado business.

Understanding Security Camera Lenses

The lens is the part of the camera that collects and focuses light onto the sensor, which then converts the light into an image.

Much like any other camera that collects still images, security camera lenses come in various types and sizes, each designed for a specific purpose. Some lenses capture a wide-angle view, while others are designed for long-range viewing or for capturing detailed images of specific areas.

Types of Security Camera Lenses

Now that we have a clear understanding of what the lens does let’s examine four of the most common security camera lenses available, along with some of the benefits and drawbacks of each.

Fixed Lenses

Fixed security camera lenses have a set focal length and cannot be adjusted. They are an excellent option for areas requiring a specific field of view, such as in a small room or hallway.

Cameras with fixed lenses generally cost less than other, more sophisticated cameras, making them an affordable option for businesses on a budget. They also have a simple installation process and are less prone to mechanical failure because of their fixed position.

However, along with a lower price point and simplicity comes a limit in flexibility in terms of zoom and focal length, making adjustments to the field of view difficult. Additionally, they may not capture details in the distance, so you may need to install multiple cameras to monitor large areas.

Varifocal Lenses

Varifocal security camera lenses allow the user to adjust the focal length manually, which means that the user can change the angle of view and the magnification of the lens as needed – offering more control over the image.

The option for manual focus adjustment is one of the most significant benefits of varifocal lenses, along with greater flexibility in placement and coverage. Zooming in or out to get the perfect shot makes these lenses perfect for larger areas that need to be monitored, such as a parking lot or outdoor area.

Additionally, security cameras with varifocal lenses can be more cost-effective than purchasing multiple fixed lenses, as just one can provide the same level of coverage as multiple lenses.

But, because varifocal lenses are more complex than fixed lenses, they can be more challenging to install and require more maintenance over time.

Zoom Lenses

You may see the terms varifocal and zoom used interchangeably when shopping for security cameras, but their functionality differs. While varifocal lenses rely on manual adjustments, zoom lenses allow the user to adjust the lens’s focal length remotely, making them ideal for monitoring large areas from a distance.

Zoom lenses on security cameras offer a range of benefits. The first benefit is the flexibility to change the camera’s field of view without physically moving the camera. This is especially helpful when camera placement is in a hard-to-reach location, or the operator needs to focus on a specific area for surveillance purposes.

Secondly, zoom lenses allow for much more detail in the captured image, allowing security operators to capture more information about a scene. This can be particularly useful when identifying specific individuals or objects, such as the license plate on a vehicle entering your parking lot.

However, one drawback of cameras with zoom lenses is that they may be more expensive and complex to install and maintain than other security cameras.

Fisheye security camera lenses provide a wide-angle view of a scene, providing up to a 180-degree view of the surroundings. Because of that wide-angle, security cameras with these lenses may eliminate the need for multiple cameras, making them cost-effective for many Southern Colorado businesses.

However, the drawback of fisheye lenses is the potential to distort the image, making identifying objects or people at the edges of the image difficult.

Choosing the Right Lens for Your Business

When choosing between security camera lenses for your Colorado business, there are several factors to consider:

Field of View

The field of view is the area that the camera can capture. A wide-angle lens is ideal when you need to capture a large area, while a narrow-angle lens is better for capturing specific details in a smaller area.

Lighting Conditions

The lighting conditions in your business will also impact your choice of lens. If your business is well-lit, a standard lens may be sufficient. However, if your business has poor lighting, you may need a lens with a wider aperture to capture clear images.


The distance between the camera and the area you want to monitor will also impact your lens choice. A zoom lens may be the best choice if you need to monitor a large area from a distance. However, a fixed lens may be sufficient if you only need to monitor a small area.


The resolution of your camera will also impact your choice of lens. A high-resolution camera will require a lens with a higher resolution to capture clear, detailed images.


Finally, your budget will also influence your lens choice. Fixed lenses are typically the most affordable, while zoom and varifocal lenses are more expensive.
