With the alarming rise in crime rates, these systems have absolutely necessary in homes, shopping areas, offices, hospitals, railway and bus stations, etc. They help us to know exactly what is going on in and around our property. The recorded videos have been incredibly helpful not only for identifying criminals but these videos can also be used in the court as evidence in order to get justice. With the admirable stride that has occurred in the technological world, the field of surveillance cameras has also been revolutionized. You will find innumerable varieties at your disposal. Nowadays, these cameras are also less expensive and more flexible than they were a decade ago. There are cameras that operate as self-contained units and there are others which can be easily disguised as everyday household objects.
However, one of the most interesting types of security cameras systems is probably an infra-red light-based night vision camera. There can be no denial to the fact that most of the crimes take place at night. It is during these times that people are asleep and, that is why, it becomes easier for the intruders to take advantage of the darkness. Therefore, during these times, your security systems must be extra-active so that it can provide you with the ultimate safety. How about an intelligent security system, then? That is exactly what the night vision cameras are. For the basics, it can be said that these cameras can record videos even at places where there is no light. These cameras use an infrared light source (generally LEDs) to ‘illuminate’ or light up a scene. A favorable point to be noted is that human eye is not sensitive to human eye and so, these sources are not detected by anybody in the area. Good infrared cameras which can light up about 100 ft are easily available in the market.
Another kind of night vision security camera features thermal energy. These cameras are considerably more expensive when compared to infrared based security cameras but are far more useful too. They usually work in a unique way. They detect the heat that is radiating off an object or a human and then convert it into an image. The image generally consists of false colors indicating the levels of the heat. The interesting thing is that these kinds of cameras do not need an illumination source. Such cameras are widely used by the military. They are also used in the factories and plants where temperature monitoring is crucial keeping track of performance of the factories’ equipment.
The night vision Security Cameras Systems that use infra red technology usually provide grey scale image. Most of such Security Camera Systems come with in-built illuminators which switch on by themselves as soon as it gets dark. There are certain factors to consider before you decide to buy a night vision camera. These factors include indoor or outdoor usage, distance of furthest are to be observed, thermal or infrared, cost, wireless or wired, etc.
