Varifocal lenses allow you to change focal length, field of view, and zooming level according to the requirement. This provides maximum coverage with a significant reduction in blind spots. The ability to adjust the focal length as needed makes them perfect for security monitoring. Because it allows the user to adjust the CCTVs according to the surroundings and what they need to capture. This is precisely why varifocal lenses are used in CCTVs to monitor different places including airports, hospitals, traffic systems, and government buildings. The reason to use varifocal lenses in such high-security areas is their ability to adapt to the environment. With these lenses, you can capture objects at a distance. Also, you can change the focal length to capture a wider area without repositioning the camera or changing the lens.
The significant benefit of using a varifocal lens is that it minimizes the need for multiple cameras. Having a CCTV camera varifocal lens can perform the tasks of both a fixed focal length and wide-angle lens camera. As a result, it helps to save money and offers better coverage with a significant reduction in blind spots. A varifocal lens may cost more than a standard lens but provides benefits worth the price.
What Makes Varifocal Lens a Better Option for Security and Surveillance?
CCTV cameras are used in a variety of places like corporate offices, warehouses, airports, retail stores, and parking. Whether covering a wider area or zooming on specific objects, each space has certain specifications and requirements. Varifocal lenses let you fulfill most of these requirements without needing extra cameras. A varifocal lens can improve security monitoring in the following ways:
- Adjustable zoom and field of view
- The adjustable field of view and zoom level are the key benefits of a varifocal lens. You can change the focal length of a varifocal lens and adjust it according to the view you need to capture. For example, you can increase the lens’s focal length to capture objects placed at a distance from the camera. Also, you can decrease the focal length to monitor a wider area. This offers a huge help in capturing different fields of view without changing the lens or the camera placement.
- Better Recognition with Optical Zoom
- Varifocal lenses are ideal for security monitoring because of their ability to provide better magnification with optical zoom. This helps to capture the details of objects placed at a distance from the camera. The magnification capability of varifocal lenses has various applications including better facial recognition which significantly increases the chances of culprit identification. Also, traffic security systems use a CCTV camera varifocal lens to identify the license plates of vehicles under suspicion or those who break traffic laws. This is all possible because varifocal lenses use optical zoom instead of digital zoom which preserves the quality while magnifying.
- Remove Blind Spots
- Varifocal lenses can cover multiple viewing angles with their adjustable focal length. That is how they can capture the field of view equivalent to the view captured by a multiple-camera setup with standard lenses. Therefore, you can replace the multiple-camera setup with a varifocal lens CCTV. As a result, this eliminates the blind spots for better and more efficient coverage.
- Save Cost
- Although varifocal lenses cost more than standard lenses, investing in them will help you save a lot in the future. These lenses eliminate the need for multiple CCTVs so that you can avoid the cost of installing and maintaining different cameras.
How Do Modern CCTV Cameras Enhance Security?
CCTV cameras are now becoming a necessity as a security solution. They help to identify suspects, collect evidence, and prevent crimes. Modern optical technology is adding more benefits to these security surveillance devices. These CCTVs are now capable of night vision, motion detection, remote monitoring, high-resolution imaging, and efficient storage facilities. Because of the aforementioned benefits, CCTVs are used at almost every place that requires security monitoring. You can also choose a C Mount CCTV Lens which allows you to use multiple lenses with a single camera interchangeably.
Modern CCTV cameras enhance the security of personal, commercial, and industrial spaces by:
- Preventing Theft and Burglary Attempts
- Multiple studies have shown that the presence of CCTV cameras puts pressure on the culprit’s mental state significantly reducing the number of theft attempts. CCTVs induce a fear of getting identified or caught in the minds of culprits. That is precisely why they avoid places with CCTV cameras.
- Better Night Vision Capacity
- Modern CCTV cameras can equip specific night vision lenses that capture clear footage at night. This is also very important because the general attempts of invasion and burglaries are high during the night when it is completely dark. Even without any special lens, modern CCTV can capture better low-light images all thanks to high-resolution lenses.
- Providing Remote Monitoring Services
- You can check live and recorded footage of CCTVs from virtually anywhere on your smart devices and monitors. This is possible as long as your smart device and the CCTV are connected to the internet.
Choosing the Right Lens and Placement
In order to fully utilize the benefits of a CCTV camera choosing the correct placement and CCTV camera lens can make a huge difference. You need to pick the right height and corner to ensure the camera captures the area effectively. Another factor that plays an important role in improving coverage is the lens choice. If you find it difficult to find the correct lens or proper lens placement or have any other questions, the team of SuperiorCCTV is here for you. We offer free consultation regarding lenses and other optical components.
Varifocal Lens or Fixed Focal Length Lens – Choose Appropriate Lens for CCTVs
Varifocal, wide-angle and fixed focal length lenses are some of the most popular lenses used in CCTV cameras. You need to remember your requirements while picking the lens to ensure better coverage. The following points will help you find the right lens:
- Limited Budget
- Varifocal lenses are more expensive than fixed focal length lenses due to adjustability and optical zoom factor. Therefore, if you have a limited budget for security, you should choose a fixed focal length lens for your CCTV cameras.
- Monitoring Objects at a Fixed Distance
- Fixed focal length lenses are great when it comes to monitoring objects placed at a fixed distance. Due to this, these lenses are mainly used in industries to monitor assembly lines or in the surveillance of hallways or small spaces.
- High-level Security
- Varifocal lenses are used in places that require high-level security and monitoring. Their ability to zoom into details and change focal length makes varifocal lenses a perfect choice for security and surveillance. These lenses allow the user to capture different fields of view without repositioning the camera or changing the lens.
- Cover a Wider Area with a Single Camera
- When it comes to covering a wide area with a single lens you can either opt for a varifocal lens or choose a CCTV camera wide angle lens. The choice depends on the further requirements and budget constraints. If you just need to capture a wide field of view and have no concern about the details, in that case you can choose a wide-angle lens. On the other hand, if you need to cover a wider area and also need zooming capabilities then a varifocal lens is a better option.
