It is a mixed assessment I make of this set. On one side, we have a quality camera, which can easily be fixed under a balcony, an infrared system that works very well and quite effective wireless broadcast. We also have a fairly simple programming system. Finally, the startup time is very limited. On the other, we have defects which I find quite surprising: for example, the image quality is very poor. We do not need 4K for video surveillance is heard, but finally, the 320 of 280 seems exaggerated to me. And the system is still full of gaps. It has no ability to put video in full screen easily. You can not disable the two small LEDs that make the camera very recognizable. And so on. For those who would raise the issue, connect the camera to an electrical outlet continuously. To observe outside, so it requires any bores walls. We must therefore assess the need before.
