Security monitoring lenses are getting more advanced with the addition of remote monitoring and cloud storage. You now have lenses that are capable of capturing high-resolution images in pitch black conditions. However, to get all these features, you will need to spend a considerable amount of money. The expense of purchasing and installing advanced lenses is profitable for large-scale industries. However, the case is completely opposite for personal and small-scale commercial properties. You do not need high-tech surveillance for your small residential areas or your garage parking. In such scenarios, using a fixed focal length lens eases the burden on your pocket and helps you with security and surveillance.
Why is a Fixed Focal Length Lens Used in CCTV Cameras?
A lens with a fixed focal length has a limited and constant field of view. Therefore, you cannot change the field of view (FOV) with a fixed focal length lens without repositioning the camera. The fixed focal length enables you to maintain a consistent view, making it suitable for high-security areas. But this lens can be, and is, popularly used in personal security and monitoring. Here are some practical applications that will explain why fixed focal length lenses are used.
1. Monitoring Personal Property
Fixed focal length lenses have limited application, but they are one of the popular lenses when it comes to monitoring small-scale properties. Therefore, these lenses are popularly used in residential areas. People use these lenses to monitor their homes or corporate offices. Fixed focal length lenses are ideal when you need to capture a constant field of view.
2. Easily Available
Another reason why you should use these lenses is their easy availability. As these are the most common types of lenses used, they are readily available. Consequently, you save a lot of your searching time.
3. To Reduce Security Cost
Choosing a fixed focal length lens results in a significant reduction in security cost. For example, instead of hiring multiple security guards, you can use multiple cameras with a fixed focal length. This way, you can monitor the property at a significantly reduced cost. The affordability of these lenses plays a significant role in reducing security costs.
4. High-image Quality
Given their affordable price, lenses with a fixed focal length provide surprisingly high-quality images. High-quality images are the primary requirement for CCTV cameras or security lenses. It helps in better culprit identification by capturing the essential details. That is why using these lenses as a security camera lens enhances security and surveillance.
5. Easy Installation and operation
Lenses with a fixed focal length are straightforward and easy to use. Their installation also takes little time and costs less, too. These lenses are versatile and can be adjusted in compact spaces. However, you should place the camera carefully, as you cannot change the focal length or field of view.
When To Use and When To Avoid Using a Fixed Focal Length Lens?
The efficiency of CCTV cameras’ coverage depends on the situation, camera placement, and the type of lens. Similarly, with a fixed focal length lens, it is essential to determine whether to use it or not. The following points will help you with this.
When to Use?
1. The ideal situation to use this lens for security is when you only need to cover a small area. Using an expensive lens to do simple monitoring is not productive. Fixed focal length lenses have a constant field of view that is ideal for monitoring compact spaces.
2. You should also turn to fixed focal length lenses when you have budget constraints. These lenses are more affordable but capture high-quality images. Being budget-friendly is a prominent reason behind the popularity of these lenses.
3. You can also use lenses with fixed focal length to monitor industrial assembly lines and production. These lenses have a constant field of view, allowing them to monitor assembly lines effectively. Industries use these lenses to reduce production errors and enhance their quality control.
4. When compared to other CCTV lenses, fixed focal length lenses are smaller and more compact. Due to this quality, you can install these lenses in crammed spaces where installing other lenses is not possible.
When to Avoid?
1. You should avoid fixed focal length lenses when you need zooming capabilities. These lenses come with a fixed focal length, which means that you cannot zoom into distant objects. That is why you should avoid using this lens in long hallways or large fields.
2. High-security areas demand flexible cameras and lenses. Using fixed focal length lenses in such places can compromise security and leave blind spots. You can use a CCTV camera varifocal lens instead when you need highly advanced security solutions.
3. A significant reason to avoid using a lens with a fixed focal length is when you need to capture moving objects. Once the lens and camera are installed, you cannot change the field of view that it captures without physically moving the camera. Hence, you can opt for other lenses that come with adjustable focal lengths.
