Installation of CCTV / IP cameras helps not only to prevent crimes due to visual control but also to charge criminals using the information recorded by video camera.
· Remote control from video cameras through Internet on any personal device (tablet, smart phone, desktop).
· Safety of people / property in office premises, at home or in a country house.

There are two types of cameras used for surveillance - analog and IP (internet protocol), which are digital cameras. Analog cameras:
These are usually lower resolution than the more modern IP technology, and require cable connections to a DVR to record and store footage, plus wired connections for power. With the DVR, the footage can be viewed on a monitor in real time or a router and modem can be connected to transmit the footage. These cameras cost less than digital cameras, but because their field of vision is smaller, more cameras may be needed. There are more design options for analog cameras, so you may find the right camera for your needs at a lower cost than digital. You also won't lose the network bandwidth that digital cameras take up. Digital cameras:
IP cameras are higher resolution, which generates clearer images but, as we said, use more bandwidth to transmit and require more storage space. Cameras connect to a network video recorder (NVR) via a PoE (Power over Ethernet) switch, which has ports for many cameras and then uses just one cable to connect to the NVR and power source. This reduces the number of cables needed but can put a drain on your network bandwidth.
There is no limitation to where cameras can be placed in relation to the NVR, and wireless network access enables remote viewing of footage. Also, the digital feed can be encrypted. Wi-Fi cameras do, however, raise the concern of potential hacking, so it is important to understand the security features of your cameras.
