The quality of security camera’s is rising.
You certainly will remember a television program where robbers or burglars are shown on foottages taken from home security cameras. Often these cameras only had 420 lines wich is reasonable if one stands very close to the camera. But that is usually not the case. The last decade the image quality is rising fast and cameras are getting much smaller. A good example are the small drone camera’s today, or the camera of your smart phone. One thinks as such a small camera is so good, why not a security camera. The reason is that the camera has to perform during day and night. Night vision for a long time is obtained with infra red light. The disadvantage or IR is the recognicion of people at night. This because the foottage is deformed as through IR you see heath.
This is a new technique in wich the camera has very low lux. This is the light sensitivity. The lower the lux the more the camera sees at night. Starlight only needs the light of a street lantern to see colour at night and to reproduce it on your screen. Thee are pure starlight camera’s, but there are also combinations with infra red for dark areas and for guarding large areas. The disadvantage of infra red is also that the camera is seen at night and that it attracks insects. It means the camera has to be cleaned more often.
a starlight camera with auto patrol.
The starlight camera shown above can auto track people and zoom in 30 times. That gives great opportunities for day and night. When central mounted it is easy to guard a large area with just one camera. Ofcourse the foottage can be seen on your smarthone and alarms can be programmed and sent direct to you.
