What’s the Best Lens for Parking Lot Cameras?

When it comes to parking lot security, having the right camera lens is crucial. The lens you choose for your parking lot cameras can make a big difference in the quality and effectiveness of your surveillance system. With so many options available, it can be difficult to know which lens is the best choice for your specific needs.

Types of Security Camera Lenses

To get started, we will discuss the four most common types of lenses for parking lot cameras – fixed lens, varifocal lens, motorized zoom lens, and fisheye lens – and explain which parts of parking lots they are best suited for.

1.Fixed Lens

A fixed lens is a lens with a focal length that cannot be adjusted. It offers a fixed field of view, which means that the camera will always capture the same amount of the scene regardless of the distance to the subject. Fixed lenses are usually more affordable and easy to install, making them a popular choice for parking lot cameras. They are ideal for capturing a specific area of the parking lot, such as entry gates, exits, or specific parking spaces.

2.Varifocal Lens

A varifocal lens is a type of lens that allows the user to manually adjust the focal length, enabling them to change the field of view without changing the position of the camera. Varifocal lenses are ideal for capturing different areas of a parking lot, such as parking spaces, entrances, and exits, without the need for multiple cameras. They are also useful for adjusting the field of view to focus on specific areas of interest, such as license plates or faces.

3.Motorized Zoom Lens

A motorized zoom lens allows the user to remotely adjust the focal length and field of view of the camera. They are ideal for parking lot cameras that require frequent changes in the field of view or zoom level, such as monitoring entry and exit points, monitoring traffic flow or tracking suspicious activity. These lenses can be remotely adjusted without the need for manual intervention.

4.Fisheye Lens

A fisheye lens is a type of ultra-wide-angle lens that captures a 360-degree field of view, allowing the camera to see in all directions at once. Fisheye lenses are ideal for parking lot cameras that require maximum coverage and a panoramic view of the area, such as large parking lots or open spaces. They can capture more of the scene in a single frame, reducing the need for multiple cameras to cover the entire parking lot. However, fisheye lenses may distort the image and require specialized software to correct the distortion.

Other Factors to Consider

Here are some of the key factors to consider when selecting a lens for your parking lot camera, which include:

Focal Length

The focal length of a lens determines how much of the scene can be captured and how distant objects will appear in the footage. A shorter focal length provides a wider field of view, capturing more of the scene but potentially sacrificing detail in distant objects. On the other hand, a longer focal length provides a narrower field of view but allows for greater detail in distant objects. A focal length of 2.8mm to 12mm is generally recommended as it strikes a good balance between capturing a wide area while still providing detailed images of distant objects.


The aperture refers to the size of the opening that allows light to pass through to the camera sensor. A larger aperture allows more light to enter the camera, resulting in brighter and clearer images, especially in low-light conditions. A smaller aperture, on the other hand, may be preferable in situations where too much light can cause glare or wash out the image. A lens with a wide aperture (f/1.4 or lower) enables you to capture clear and detailed footage even in poorly lit environments.

Image Sensor Size

The image sensor size of a camera plays a significant role in determining the quality of the footage it captures. Larger image sensors are generally better at capturing more light and detail, resulting in clearer and more detailed images. For parking lot cameras, image sensors with a size of 1/2.8″ or larger are recommended as they offer better performance in low-light conditions and provide higher resolution footage.

Night Vision

Many parking lots are poorly lit or completely dark during the night, so cameras with low-light performance are essential for capturing clear footage in low-light conditions. Look for a lens that has built-in infrared illuminators because IR light is invisible to the human eye but is detected by the camera’s sensor, allowing for clear imaging in complete darkness, which enables you to identify any suspicious person or vehicle more effectively. Make sure it has a wide aperture (low f-stop) to allow more light to enter the camera, as well as features such as infrared cut filters and a wide dynamic range to improve visibility in low-light conditions.
