By type of housing

Two categories can be distinguished in this parameter:

Open-frame model - is small in size and low efficiency. It is a card in which is embedded a low quality camera and a microphone for recording an audio signal. Another feature can be called a complex and lengthy installation process.

Hull model - a more reliable and popular option. Video data devices are relatively simple to install, look spectacular, and stand a decent quality image on a monitor and a clear sound. But there is a drawback - such equipment is more expensive unpackaged products.

Black-and-white (monochrome) - cheap eyes camera is equipped with such a set of colors. For the majority of cases of this combination is enough to fully see the guests and visitors.

Color - installed in more expensive units. It has more aesthetic than a practical advantage.

wire models - for the supply of electricity, doorbell and video data, various types of wires. Such decisions require a very time-consuming installation and can not boast of mobility. On the other hand, such devices are characterized by high stability and quality of the signal.

Cordless models - as the name implies, it is not necessary to pull the separate wiring and drill into the door a special hole for the eye. The power source in this case is either a rechargeable battery or batteries. A data transmission is responsible integrated Wi-Fi or Bluetooth-module.
