CCTV, or closed-circuit television, is a security device that allows you to monitor your personal, commercial, and industrial property. Initially, the installation and maintenance of CCTV cameras were costly. Therefore, they are only used for military and commercial purposes. However, modern technology has made CCTVs more user-friendly and affordable. You can now see CCTV cameras at every commercial location, and their popularity for personal use is also growing significantly. The major credit for the popularity of CCTV cameras goes to the flexibility and availability of multiple lenses. A CCTV camera wide angle lens is one such lens that offers benefits for personal as well as commercial use.
Benefits of Using a Wide-Angle Camera Lens for Security and Surveillance
A wide-angle lens has a shorter focal length, and hence it offers a broader field of view. As a result, these lenses let you cover a wider area with a single lens. It would take multiple standard focal length lenses to cover the area, whereas a single wide-angle camera lens can cover the same location. Therefore, it offers you a significant advantage when you need to cover a larger area and have a low budget. Using a wide-angle camera lens can save you from the expenses of installing and maintaining multiple cameras. While a wide-angle CCTV camera lens can cover a larger field of view, it cannot capture detailed images. In this blog, we will explore where to use and how to efficiently use wide-angle lenses for security and surveillance.
Where to Use Wide-Angle Lenses for Security Purposes?
Wide-angle lenses are excellent at capturing a broader field of view. However, it is essential to know how and where to use these lenses to get better coverage. Here are some crucial points to keep in mind:
1. To Capture a Wide Field of View
This is the primary benefit of using a wide-angle camera lens. Due to their shorter focal length, these lenses can capture a broader field of view. Consequently, using a wide-angle lens is beneficial if you need to cover a larger area efficiently. You will mostly see these lenses at industrial and commercial sites, where standard lenses can cover the whole area. Large warehouses, retail stores, public parking areas, fields, and industrial facilities are some common locations where wide-angle security cameras are commonly used.
2. Capturing Multiple Spaces at Once
Due to their wide field of view, a CCTV camera wide angle lens is used to cover multiple spaces at the same time. Therefore, you will commonly observe wide-angle cameras being used in places like banks and stadiums. You can use a wide-angle lens CCTV to monitor multiple doors simultaneously. Similarly, wide-angle lenses can capture different angles and perspectives of a stadium, which helps with crowd control.
3. To replace the Multi-camera System
The only way to capture a larger field of view with standard lenses is to use a multiple-camera system. However, there are multiple problems with using this multi-camera system. It can significantly increase the cost as you will need to install various cameras. On the other hand, a multi-camera system can compromise the coverage by creating blind spots. Therefore, in such cases, it is wise to choose a wide-angle CCTV lens. It can easily replace the multi-camera system while providing the equivalent coverage.
4. When Details are Not Important
This is a crucial point to keep in mind if you are picking a wide-angle lens for security and monitoring purposes. Wide-angle lenses are excellent at capturing large areas. However, they produce a slightly distorted image that lacks details. Therefore, it is not wise to use these lenses for facial or vehicle recognition purposes. Use them to capture large areas and monitor the movements of people or large machinery.
5. Budget Constraints
Wide-angle lenses are also considered to be budget-friendly. You should consider these lenses when you have a tight security budget. With wide-angle lenses, there is no need to buy and install multiple cameras. As a result, you save a lot on installation and maintenance costs.
Other Common Security and Surveillance Lenses
Technological advancements in the field of optics have led to the development of various lenses with distinct qualities and specifications. These lenses come with distinct specifications and usage areas. Some of these lenses have the ideal attributes for security and surveillance purposes. Here are some popular lenses that are used for security and monitoring:
1. Varifocal lens
As the name suggests, a CCTV camera varifocal lens has an adjustable focal length. In simple words, you can change the focal length of these lenses according to your needs and requirements. These lenses offer you the ability to capture a wider field of view, and at the same time, they can capture details too. You can increase the focal length of these CCTV cameras and zoom in on distant objects. Due to this dual ability, varifocal lenses are used in high-security areas. The traffic control system also uses these lenses to capture detailed images of vehicles and their license plate.
2. Fisheye lens
Although fisheye lenses are generally not suitable for surveillance, as they produce a highly distorted image. However, there are exceptional cases where using CCTV fisheye lenses can provide better coverage. They can capture a wider field of view than wide-angle lenses. Fisheye lenses can capture from 100 to 180 degrees. Although they have limited and specific areas of use, fisheye lenses can prove to be very beneficial when capturing crowded places.
3. Fixed Focal length lens
A fixed focal length lens is a straightforward lens used to capture objects at a constant distance from the camera. Fixed focal length lenses are a cost-effective security solution commonly used in public places for surveillance purposes. In addition to this, these lenses are used to monitor assembly lines in various industries. They play a crucial role in industrial quality control.
