Varifocal lenses are specialized and advanced lenses with an adjustable focal length. It allows you to capture multiple fields of view without changing the lens or the camera position. This lens will enable you to monitor a larger area and provide you with zooming capabilities. The zooming capabilities prove to be highly beneficial in identifying faces and vehicles. Due to these qualities, a CCTV camera varifocal lens is used in high-security areas. Airports, government buildings, industrial areas, and traffic surveillance are among the central locations that are monitored using varifocal lenses. Using a varifocal lens for security and monitoring can significantly increase the security, offering you peace of mind.
Varifocal lenses offer much better security than standard lenses as they are more versatile. It means that you can use these lenses to monitor different places. You can use them to capture footage of long halls, wider areas, or crowded places. In each case, a varifocal lens will provide you with effective coverage, which is essential for high security. A varifocal lens is comparatively more expensive than any other standard security camera lens. However, they can prove to be a cost-effective security solution in the long run. They can capture multiple fields of view without needing to change the lens or camera position. As a result, you do not need various security cameras, and you can avoid installation and maintenance costs.
Why Do You Need a Security Camera with a Varifocal Lens?
The primary reason to use a varifocal lens for security is its adjustable focal length. It allows you to choose what you want to capture. You can shorten the focal length to cover a broader area. On the other hand, you can use the varifocal lens’s zooming capabilities. As a result, a CCTV camera varifocal lens provides you with the freedom to capture what is required.
Their ability to identify faces and vehicles is essential for monitoring sensitive and high-security areas. Consequently, it facilitates the process of identifying the culprit. Another striking feature of varifocal lenses is their high-quality imaging. Due to the enhanced image quality and zooming capabilities, these lenses are also used in industries. Varifocal lenses are used in industrial machine vision systems and to monitor the manufacturing process.
Situation and Places Where Varifocal Lenses are Beneficial
Due to the versatility of a varifocal lens, these lenses can be used in multiple places and situations. The following points will help if you are also planning to use it as a security camera lens for your private or commercial property:
1. Identification and Capturing Close-Up Details
These lenses are designed so that you can adjust their focal length and zoom into distant objects. Varifocal lenses are an ideal option for capturing detailed images for verification and identification purposes.
2. Replacing Multiple Cameras
A varifocal lens can capture multiple fields of view. On the other hand, you will need to install a multi-camera setup to capture different fields of view. As a result, it will increase the installation and maintenance costs. You can avoid these unnecessary expenses by replacing the multi-camera setup with a CCTV camera varifocal lens. It will also help you eliminate blind spots in the coverage.
3. Monitoring High-Security Regions
Trusting standard lenses to monitor high-security regions is not recommended. As it can generate blind spots, the image quality is also relatively low. Using a varifocal lens addresses these issues and provides additional security benefits. Therefore, you will generally see varifocal lenses being used in government offices, where high-level monitoring is required.
4. Additional Uses
Varifocal lenses are primarily used for security and monitoring purposes. However, these advanced lenses have other uses in industries. Varifocal lenses are popularly used in industrial machine vision systems for automation tasks. Additionally, you can use these lenses to monitor production and assembly lines accurately.
When to Avoid Using CCTV Camera Varifocal Lens?
Choosing the right security camera lens is crucial for achieving better coverage and enhancing surveillance. While varifocal lenses are more advanced, they may not be a good fit for certain situations. Some of those situations are listed below to give you a better idea:
1. Budget Constraints
Varifocal lenses are more expensive than standard lenses. Although their price comes with more benefits, you can consider other options. For example, it is better to use a fixed focal length lens when you need to capture a constant field of view. Lenses with a fixed focal length are considerably cheaper than varifocal lenses.
2. Budget Constraints
The adjustable focal length and the ability to capture multiple fields of view are not required everywhere. Monitoring small spaces and private properties does not require capturing multiple fields of view (FOVs). Alternatively, you can use other specialized lenses, such as a zoom lens, a wide-angle lens, or a fisheye lens.
3. Budget Constraints
While varifocal lenses can capture a wider field of view, there are other lenses that can do it better. Instead of a varifocal lens, you can opt for a CCTV camera wide angle lens. It will allow you to capture an ultra-wide field of view at a considerably reduced cost.
