A security camera with a 3.6mm lens is designed to provide an approximate 78° field of view, making it suitable for most CCTV applications.
2. What lens is used in CCTV cameras?
In CCTV cameras, the lens used depends on the camera’s chip size. For a 1/3-inch format, a wide-angle 2.8mm lens offers a horizontal field-of-view around 74 degrees, a standard 8mm lens offers around 30 degrees, and a telephoto lens of 50mm narrows the field of view to less than 5 degrees.
3. How can I make my CCTV camera better quality?
To enhance the quality of your CCTV footage, choose a camera with the ideal resolution, improve the lighting around the camera, and use infrared illuminators to improve night vision.
4. What is the highest CCTV quality?
Legacy CCTV systems use an analog video signal, and the highest resolution that can be captured and stored is 704 x 480 (NTSC for the United States) and 720 x 576 (PAL for Europe), which is known as D1 resolution.
5. Which is better, a 2.8mm or 4mm lens?
There is about a 20% difference in viewing angle and image quality between a 2.8mm and 4mm lens.
6. How many MP should a security camera have?
Common resolutions for home security cameras include 2MP (1080p), 4MP (1440p), 5MP (1920p), and 8MP (4K/2160p).
7. What is the maximum range of a CCTV camera?
CCTV cameras can detect intruders up to 250-300 meters away and are good in low-light conditions. Thermal radiation can pass through visual barriers.
8. How do you clear blurry CCTV images?
Check the security IP camera lens for dirt, dust, or spiderwebs and clean it with a soft cloth. Avoid using harsh or aerosol cleaners that may damage the lens.
9. Why is my CCTV camera always blurry?
A dirty or watery lens can be the cause of blurry images. Check the camera lenses for dirt, rainwater, or spiderwebs and clean them following the manufacturer’s guidance.
10. Which CCTV camera is best for night vision?
Some top brands known for their night vision capabilities include Blurams, IFITech, Mi, CP PLUS, Cpixen, TECHNOVIEW, IBS, and CFFTED.

4K offers a higher resolution with quadruple the number of pixels compared to 1080p, allowing for better details and visibility, especially for distant objects and faces.
12. How far can a 2.8mm lens see?
A camera with a 2.8mm lens can typically see up to 1.5 meters.

Is 4K better than 1080p for CCTV
4K is defined as a 3840 × 2160 resolution video, with quadruple the number of pixels (detail) compared to full 1080p HD video. In video surveillance, 4K gives you more ability to see details such as faces at a farther distance compared to the same image using a 1080p camera.
How far can a 2.8 mm lens see
| 2.8mm lens | 1.5 metres |
|---|---|
| 6mm lens | 5 metres |
| 9mm lens | 6 metres |
| 12mm lens | 7 metres |
| 22mm lens | 12 metres |
What is the difference between 3.6 mm and 6mm CCTV camera
Lens focal length is measured in millimetres (mm) and the smaller the number is, the wider the viewing angle will be. This means that objects viewed through a 3.6mm lens will appear smaller and farther away than if they were viewed by the same camera using a 6mm lens or larger.
Is 4K or 12MP better
12MP Mega High Definition
Swann's highest resolutions available (yet) is world-leading 12MP Mega HD for security cameras. With 12.6 million pixels, 12MP resolution has around 50% more pixels than 4K. 12MP is formatted in a 4:3 aspect ratio. This sets it apart from 4K and 1080p, which are both in the 16:9 aspect ratio.
Does higher MP mean better camera
It's no longer true that the higher a camera's megapixel count the better. The only thing more megapixels will give you is the ability to enlarge and crop pictures without individual pixels becoming visible. Other factors are much more important in determining overall picture quality.

It actually depends on the size of the screen and where you are sitting. From a distance, it is virtually impossible for someone to tell the difference in quality between a 1080p and 4K screen. However, if you have a big enough screen, in a small enough room the difference is immediately apparent.
What is the difference between 2.8 mm and 4mm camera lens
For fixed lenses, you will often find them in two common varieties; 2.8mm and 4.0mm. In this case, the amount of mm is referring to the focal length of the camera lens. A shorter focal length (2.8mm) results in a wider angle shot, while a longer focal length (4.0mm) results in a narrower shot.
How many megapixels is best for CCTV
2MP cameras are already considered high definition (HD) cameras, while those that reach or exceed 8MP fall into the ultra high definition category (UHD). These are the security camera resolutions that are most widely used as they provide a high level of detail.
