There are many different versions of the two cameras, the main differences between them are the interfaces they have, and whether or not they are compatible with particular hardware or platforms. 1. OV2640 & OV7670 CCM Camera Module In general a 5MP 2.8mm lens will offer you around 105° field of view and a 5MP 4mm lens will offer you an 87° field of view. It's a common misunderstanding that the smaller the lens, the less detail you'll caputre but this is definitely not the case. The size of the lens purely correlates to the amount the camera caputres in the FOV. Any resolution over 1 million pixels is considered 'megapixel'. In the case of megapixel cameras, the labels are approximate. For example, a 2 megapixel camera actually captures 1,920,000 pixels per frame. A 3 megapixel camera captures 3,145,728 pixels per frame.

Also, each camera was left on default settings as a fair baseline comparison. See below for the list of cameras used for this test: IPC3614SR3-ADF28KM-G – 4MP IP Camera. Resolution – 2688*1520 (4.1 mega pixels) Lens – 2.8mm Lens; Angle of View (H) – 101.1° / Angle of View (V) – 55.3° IPC3615SB-ADF28KM-I0 – 5MP IP Camera

The most used aspect ratios are 3:2 and 4:3. For example, my Canon 5D MkIII has a 3:2 aspect ratio. Its sensor measures 5760 pixels on the long side, and 3840 pixels on the short side. You can multiply the two sides to get the total pixel count. 5760 x 3840 is equal to 22,118,400.
No. This is the most important part of understanding why 48-megapixel cameras are a good thing: it’s not about quality. Megapixels are not a measure of camera or photo quality. A camera with Major Similarities between 5MP vs 8MP Security Camera: When it comes to resolution for security cameras, 5MP and 8MP cameras are widely available. While there are differences between the two, they are similar in many aspects: Both 5MP and 8MP security cameras have high-resolution capabilities that provide clear and detailed images. Several of them match the resolutions being used on PCs, laptops, and HDTVs. 2MP: 2MP security cameras have a 16:9 aspect ratio, 2,073,600 pixels per image, and an image size of 1920 x 1080 pixels or Full HD 1080p. 3MP: 3MP security cameras have a 4:3 aspect ratio, 3,145,728 pixels per image, and an image size of 2048 x 1536 pixels or 1536p. aoFZ.
