C-mount and S-mount lenses are two completely different lenses, with distinct sensor sizes, mount types, and industrial applications. An S-mount lens is a compact and affordable lens series used in CCTV cameras with smaller sensors. This makes them an ideal choice for residential security monitoring services, where standard resolution is sufficient and budgets are limited. Another benefit of using S-mount or M12 lenses is their interchangeability. It allows you to use different lenses with the same camera, as long as you have the appropriate mount type or adapter.
On the contrary, c-mount lenses are primarily used in industrial applications with cameras that have a larger sensor size. They provide high-resolution images and can capture greater details than s-mount lenses. That is precisely why industrial manufacturers use a C mount telecentric lens for a machine vision system, where high-resolution imaging is a critical requirement.
Further in this blog, we will understand the technical difference between C and S-mount lenses and learn about the characteristics of S-mount lenses in detail.
Technical Differences Between C-Mount and S-Mount Lenses
The following section compares C-mount and S-mount lenses, on technical and other parameters. Understanding the difference is crucial to choosing the right lens for your particular applications. Let’s go through the technical differences one by one:
1. Thread Size
The thread size of a lens is essential for attaching accessories and using adapters. An S-mount lens features a 12mm thread diameter and a 0.5mm thread pitch. Due to their standard 12mm pitch size, S-mount lenses are also commonly referred to as M12 lenses. Meanwhile, a C-mount lens is equipped with a 1-inch (25mm) diameter, which is significantly larger compared to the thread size of S-mount lenses.
2. Physical Dimensions
As discussed in the above section, S-mount lenses feature a smaller thread size. As a result, they are more compact and smaller in size than C-mount lenses. Due to its smaller size, an S-mount or an M12 CCTV lens is much more suitable for tight space installations. However, when it comes to high-level security monitoring, without placement constraints, c-mount CCTV lenses are preferred over s-mount lenses.
3. Sensor Size Compatibility
C-mount lenses are designed for large sensors of the standard 1-inch format. Meanwhile, M12 or S-mount lenses are compatible with much smaller censors up to ⅔ inches. The sensor size governs the image quality and low-light performance of the lens. Therefore, c-mount lenses with larger sensors are the optimal solution for high-level security monitoring around the clock.
4. Focus
S-mount lenses typically have a fixed focal length, meaning they can only capture a fixed field of view. On the other hand, c-mount lenses are more versatile and come with adjustable focal lengths. Therefore, it allows you to capture the preferred field of view without changing the lens or camera location. Even with a constant field of view, an S-mount lens proves to be quite helpful in smaller spaces, such as residential areas and corporate offices.
5. Image Quality
There is a significant difference in the quality of images captured by these two lenses. S-mount lenses, due to a shorter sensor size, capture low-quality pictures and videos. That is why, in industries and applications where higher resolution is required, the C-mount lenses are the prominent choice.
6. Installation and Operational Cost
When it comes to cost-efficiency and budget-friendly security solutions, S-mount or M12 lenses are a better choice. These are affordable lenses that deliver the job done and provide excellent coverage for the budget range. Additionally, compact size and simple working make them easy to install around the property.
In the case of a C mount telecentric lens or installing a C-mount CCTV lens, the process is more costly and complex due to the technical requirements. Multiple factors contribute to this higher price, including professional assistance, specialized equipment requirements, and expensive lenses, among others. However, you can cut this cost down with the right CCTV lens manufacturers. For example, with SuperiorCCTV, you can get a wide range of lenses for security monitoring at the right price. We also provide free consultation regarding lenses and other optical components.
