The ingress protection (IP) is an internationally standardised code that identifies the resistance of electrical appliances against the ingress of foreign items and liquids, especially water. It is expressed in the so-called IP code, which consists of the "IP" followed by two digits: the first indicates the protection against dangerous contact and foreign objects, the second indicates the degree of protection against water ingress.
CMOS chips are often used in digital cameras. Compared with CCD sensors, they offer a cheaper alternative, with lower power consumption and faster data transfer. CMOS sensors are able to transmit data from each point separately, while CCD sensors work line by line. CMOS sensors are sometimes abbreviated as APS (Active-Pixel Sensor).
Resolution indicates the number of pixels that make up an image or video. A lot of modern devices are equipped with Full HD resolution (1920 x 1080), which is suitable for display on large screen TVs or monitors. Higher resolution provides smoother images with more detail.
CCD is a sensor type that records colour images. Image recording is performed by two methods: the location of RGB filters in front of the sensor or filters are placed in front of the pixels in a checkerboard pattern.
Focus is a process that ensures the subject of a photograph appears clear and sharp. Focus can be achieved using an optical element in the lens, allowing you to focus on objects that are close or distant.
Memory cards are the medium on which images and videos are stored. Cards can be chosen by type, capacity, writing speed and brand.
