IPS stands for in-plane switching, a type of LED (a form of LCD) display panel technology. IPS panels are characterized as having the best color and viewing angles among the other main types of display panels, TN (twisted nematic) and VA (vertical alignment). However, IPS panels are also the most expensive of the three.

It's the distance between the camera and the subject you have focussed on.

A megapixel (MP) is a million pixels; the term is used not only for the number of pixels in an image but also to express the number of image sensor elements of digital cameras or the number of display elements of digital displays. For example, a camera that makes a 1280 × 720 pixel image (921,600 finished image pixels) typically uses a few extra rows and columns of sensor elements and is commonly said to have "1.0 megapixels" or "1.2 megapixels", depending on whether the number reported is the "effective" or the "total" pixel count.

In photography, angle of view describes the angular extent of a given scene that is imaged by a camera. It is used interchangeably with the more general term field of view. It is important to distinguish the angle of view from the angle of coverage, which describes the angle range that a lens can image.

IP stands for "Ingress Protection" and is the International Protection Marking per IEC standard 60529. The most common use of an IP rating is how protected a product - such as a transducer - is from a solid or liquid entering the product.IP67 rated will remain protected and fully operational in most industrial applications, including those where the transducer is exposed to water spray, rain, debris, etc. The "6" indicates the sensor is completely protected against solid objects from entering the camera, including dust, while the "7" indicates the camera can be completely submerged in 1 meter of water for up to 30 minutes before the moisture penetrates the housing.

The No.1 reason that cause those blurry images are the dirts or oil(endoscopes) or ear wax(otoscopes) being stuck to teh tip of the camera. Please use a cloth, aclcohol pad, or a Q-tip to clean it. You can apply a little pressure to make sure you get all the dirts, oil, ear wax off the tip of the camera.

No, all the endoscopes we sell are not for medical use and it's prohibited to put into human body.
