The minimal cost of digital cameras with high resolution and ease of organization video surveillance with their help via the Internet has made them a popular solution not only for large-scale commercial security networks but also for the private needs. Mini IP cameras are bought as a nanny-cam for children or elderly parents to have the oppotrunity to always be observed simply by opening the browser or IPEYE app on a smartphone. The security of private real estate, for example, cottage houses and garages, can be provided with their help, especially with the possibility of configuring SMS or e-mail notifications when a motion detector starts working, while some people find even more original ways of applying them, even for round-the-clock shooting of urban landscapes. In order to choose an IP camera for any of these purposes, and possibly even the universal one, having the Wi-Fi module, it is worth considering the basic characteristics of such devices.
In general, the price of an IP camera (not taking into account the markup for a well-known brand) is determined by the following components:
The minimum video resolution that is currently considered sufficient for surveillance systems is 720p(HD). In most cases it is provided by budget cameras with 1MP lens, and two megapixel ones will be able to provide FullHD and higher quality.
You need to select the focal length on the basis of the following considerations: the smaller it is, the larger area will fit into the shot and vice versa. The angle of view of the human eye, which is about 45 o, corresponds to f-50mm. Another point is the number of frames per second. It is better to choose cameras with a standard indicator of 25 frames per second, especially if they are equipped with a motion sensor, otherwise there is a chance that the device will not notice the «stranger» in the observed area.
The light sensitivity of the camera is indicated in luxes, most cameras can shoot up to 0.5lx in color, which is approximately equivalent to clear moonlit night, and in the complete darkness they work with the infrared illumination turned on. Radiation of diodes is not visible, but when purchasing it is important to pay attention to what radius of illumination they provide.
