Users have the flexibility to choose between 24/7 recording or motion-triggered recording based on their specific needs, making it a versatile option for various security requirements. ... Duo 3 PoE is a powerful and reliable PoE security camera. It offers 16MP Ultra HD video quality, which is more than exceptional. It unveils intricate details and offers an immersive visual experience. Its dual-lens covers 180⁰ panoramic view to capture every moment and cover a wider area. This means that the image frame has 2048 pixels in each row and 1536 pixels in each column. The total number of pixels in a frame would be 3,145,728, approximately 3 million pixels. The word "MP" refers to one million pixels, which is why the resolution is called 3MP. An IP camera with a resolution of 2048 x 1536 pixels or 3MP total pixels is referred to as a 3 Megapixel camera. Its camera sensor is capable of recording videos at this resolution. If you want better quality, features, and future-proofing, you can go with our shared 4K video cameras. ...

What does a megapixel designation on a lens actually mean? - ...

And I get 1/3 inch lens, 1/2.5 inch and so on. But I see many lenses which say 2 mega pixel lens on them (like in this aliexpress listing). What does this actually mean? ... Both Samsung and Edmund Optics use the name "Megapixel" or "MegaPixel" to describe lenses they sell for C-mount and CS-mount cameras, but in both cases the term is used like a brand name rather than a description of any technical aspect of the lens. There's also a perceptual megapixel concept developed by DxOMark to describe lens sharpness in a way that's supposed to be more accessible than traditional MTF charts. As far as I can tell, this "P-MPix" rating hasn't really caught on yet even though it was introduced a few years ago. The example you cited is a very small, very cheap (under $6!) lens meant for a closed-circuit TV camera. It's hard to tell exactly what the "3 mega pixel" descriptor really means, and in fact it may not mean much of anything. \$\begingroup\$ Or that if you use it with anything more dense than 3MP you're only going to see results as sharp as a 3MP sensor could deliver. \$\endgroup\$ ... \$\begingroup\$ @MichaelClark Exactly -- I didn't mean to imply a real prohibition, just a lack of benefit. \$\endgroup\$ ... Sensors are manufactured to have a certain number of megapixels. Each photosite on a sensor, either CCD or CMOS, is used to generate a pixel based on the charge accumulated as a result of light falling on the corresponding light-sensitive area. A lens is made of continuous transparent material like glass, ceramic or plastic. \$\begingroup\$ Megapixel ratings on lenses are a thing with utility video cameras (CCTV, industrial...) ... and that's just where the lens in question appears to be from.

Misconceptions of Megapixel Machine Vision Camera Lenses

As much as I detest the nomenclature of “5MP lens” etc., I do appreciate what Fuji does; as they will state, “…. This series of high-resolution lenses deliver 3.45um pixel pitch (equivalent to 5MP) on a 2/3″ sensor”. Now this make more sense! In turn, if you see a lens stated as a “Megapixel Machine vision” lens, question this! It really needs to be stated in terms of its capability to resolve the pixel size in LP/mm! 1stVision has a staff of machine vision veterans who are happy to explain this in more detail and help you specify the best lens for your application! Blog post: Demystifying Lens performance specifications · Blog post: Learn about FUJI’s HF-XA-5M (5 Megapixel) lens series which resolves 3.45um pixel pitch sensors! What does this mean? As an example, Sony has recently introduced a new line of image sensors which have 5MP, 9MP and 12MP sensors. Many clients have called and said, “I want to use the 12MP sensor, so please spec a lens that can do 12MP.” Unfortunately, this isn’t correct as each of these sensors uses a 3.45um pixel. There has been a lot written about the ratings of machine vision lenses. 1stVision had created white papers that describe this in detail. However, the lens industry continues to use the marketing term, Megapixel Machine Vision Camera Lenses.

While the LP/MM lens rating was not generally provided by lens manufacturers in the past, it is becoming more common with the adoption of megapixel technology and can be useful in specifying a lens today. However many manufacturers will use a simplified lens rating for the megapixel specification (e.g. 1.3 or 3 MP) and standard sensor size (e.g.1/2 or 1/3 inch). Theia Technologies' is a leading seller of multi megapixel industrial lenses integrated in CCTV, Surveillance, Security, Machine Vision, Trafffic industries With today’s high-resolution, megapixel cameras the lens might be the most important accessory to specify with each megapixel camera. After all, if the lens doesn’t provide the resolution that the camera is capable of producing, you’ve simply wasted your investment on a higher resolution camera. By Mark Peterson, Theia Technologies, Vice President Advanced Technology Mark S. It’s true. Many manufacturers refer to their products as a “megapixel lens” but they seldom define what the adjective “megapixel” means. Is that “MP” lens to be used with a 1.3 megapixel camera or a 3 megapixel camera?

The lens is a 1/3 inch format unit, and features an IR compatible coating to address focus shift under artificial illumination. Bosch: LVF-5005C-S4109 The LVF-5005C-S4109 is a varifocal SR-iris lens with a focal length of 4.1-9mm and an aperture of F1.6–F5.2. It is rated for 5 megapixel video, making it suitable for HD1080P and higher resolution cameras. The lens is a 1/1.8 inch format unit, and has been designed for use with specific Bosch cameras. This means that the lens cannot be used with other devices, as it requires data from the camera’s processing engine to function correctly. Given the advances made in higher resolution video in recent years, it is astonishing that in many cases little attention is paid to the selection of lenses. Any camera’s performance will be affected by the choice of lens, and HD1080P cameras are an investment made to achieve higher quality. Tamron: M13VG288IR The M13VG288IR is a varifocal auto-iris lens with a focal length of 2.7-8mm and an aperture of F1.2. It is suited for use with Full HD cameras as it is rated for 3 megapixel video. The lens features an aspherical profile, and uses Flat Field technology to ensure sharp coverage, even on the edge and in corners of the image. A point worth noting is that not all megapixel lenses are the same! Most will be given a rating dependent upon how precise they are. Typical ratings are 1, 3 and 5 megapixels. It must be remembered that these ratings will be given for a 4:3 image, so an adjustment to the figure will need to be considered if the final image is 16:9, such as with HD video.
