Matrix size
The physical size of the sensor in the pointed cameras is diagonally, in inches (fractions of an inch).
The larger the sensor, the less prone it is to noise, the better image quality it can provide, and the better it is suited to low light conditions. This is due to the fact that each individual pixel gets more light, because. on a large matrix and individual dots are larger. On the other hand, large matrices are more expensive.
Number of megapixels
Sensor resolution of pointed cameras in megapixels (millions of pixels).
Higher resolution allows you to get a more detailed "picture". However, increasing the number of megapixels without increasing the sensor size can result in poor overall image quality and noise, especially in low light. Therefore, in itself, the high resolution of the matrix does not guarantee high quality shooting.
Horizontal viewing angle
The viewing angle of the directional cameras supplied as standard is horizontal.
Wide viewing angles allow you to cover a large area; this is especially important given that directional cameras are often made stationary. On the other hand, all other things being equal, a larger viewing angle will mean a lower degree of magnification - objects will look smaller, detail will be worse. Therefore, when choosing according to this parameter, you should proceed from what is more important - a wide field of view or “range”.
HDMI
The number of
HDMI connectors provided in the design of the complete registrar.
The HDMI interface is actually a standard for modern video equipment, it is widely used in TVs, monitors, projectors, etc. Usually, in modern registrars we are talking about HDMI outputs. This output allows you to broadcast a digital signal to an external screen, such as a TV; at the same time, both video and audio are transmitted via a single cable, and the bandwidth is enough to work with HD resolutions and multi-channel audio. The recorder itself can be used as an external video player, to play the footage, or directly broadcast video / audio from the camera (cameras) via HDMI. Models where there are more than one such outputs are practically never found.
VGA
The number of
VGA connectors provided in the design of the complete registrar.
The VGA output (also known as 15 pin D-Sub) is for analogue video output (audio must be transmitted separately). Some time ago, this interface was quite common, but with the development of more advanced digital standards, it has lost its popularity, and today it is relatively rare (in particular, in some TVs and monitors).
