Description

Motion recognition CCTV security lighting equipment using sunlight {MOTION RECONGNITION BASED CCTV SECURITY LIGHTING DEVICE USING SOLAR ENERGIES}

The present invention relates to a lighting device for CCTV security that recognizes motion using sunlight, and more particularly, it is very easy to install outdoors without a power cable by installing a solar charging module that condenses sunlight, and detects moving objects around it. Thus, it relates to a lighting device for CCTV security that recognizes motion using sunlight that allows the surrounding image to be recorded through a surveillance camera while the security light is on.

As society develops and the floating population by region increases, various crime accidents are increasing. Early response is very important to crime incidents that occur in not only cities where the population is concentrated, but also in local small towns and rural areas. Although the central government and local governments are preparing more manpower and countermeasures to maintain security, there are limitations in preventing and responding to crime.

In addition, streetlights are installed high on dark roads, sidewalks, or around apartment complexes to prevent accidents and crimes by ensuring sufficient visibility for drivers or pedestrians, and are usually automatically lamps when the sun goes down. It is configured to turn on and turn off at the same time as sunrise.

On the other hand, as the housing type is changed to apartment complexes such as apartments and villas, the function of streetlights is also simply surrounding the playgrounds around apartments and villas, as well as the rate of crime at night in relatively dark and uninhabited alleys. In addition to the role of revealing the information, attempts have been proposed to perform the function of preventing crime.

However, in places where such streetlights are not installed, they become vulnerable to crime prevention.Moreover, these streetlights perform the role of security lights.However, since power must be obtained separately from the telephone pole for power supply, it is difficult to install it in the right place if necessary, causing problems. .

In addition, conventional street lights are always lit at night even though dimming is not necessary when there is no human or car traffic due to rare human traffic, and energy is wasted. Even if an accident occurs in the vicinity, there is no way to notify the surroundings of the site situation. It is a very vulnerable reality.

In addition, a separate power supply is also required for security lights or CCTVs to detect the intrusion of a thief even outdoors, and such power supply makes it difficult to install in the right place.

Accordingly, there is a growing demand for CCTV security, which overcomes the irrationality of such conventional CCTV and security, and is very easy to supply power and is easy to install.
