subject: Night Vision Security Cameras Systems [print this page] If you are a business owner or a homemaker, security camera systems will definitely play a significant role in improving the level of security as well as the peace of mind you will gain. With the increase in crime rates, these systems are becoming necessary in homes, shopping areas, offices, railway, hospitals and bus stations. These security cameras will help you to know exactly what is going on in and around your property. The recorded videos will be helpful not only in identifying criminals but these videos can also be used in the court as an evidence in order to give justice. With the revolution in the technological world, the field of surveillance cameras has also been revolutionized. Nowadays, these cameras are less expensive and more flexible than they were before some time.
One kind of security camera systems is probably an infrared light-based night vision camera. No one can deny this fact that most of the crimes take place at night. During these times that people are asleep and, that is why, it becomes easier for intruders to take advantage of this darkness. Therefore, during this time 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. These cameras are very important because they can record video even at places where there is no light at all. These cameras generally use an infrared light source (generally LEDs) to 'illuminate' or light up a scene. A favorable point to be noted is that the human eye is not sensitive to the human eye and so, these sources are not detected by anybody in the area. Good infrared cameras which can light up about 100 feet are nowadays easily available in the market.
Another type of night vision security camera features thermal energy. These cameras are more costly when compared to infrared based security cameras but are far more useful too. They usually have a unique way of working. They first detect the heat that is radiating from an object or a human body and then convert it into an image. The image mainly consists of false colors indicating the levels of the heat. The interesting thing is that these kinds of cameras do not need any illumination source. Such cameras are widely used for military purpose. They are also used in the factories and plants where temperature monitoring is crucial keeping track of the performance of the factory's equipment.
The night vision Houston Security Cameras Systems that use infrared technology most of the times provide a grayscale image. Most of such Security Camera Systems come with inbuilt illuminators which gets switched on as soon as it gets dark.
