Story

The high crime rate along with the development of technology and today's era causes a security system to become an absolute necessity to be implemented, in order to protect assets and privacy owned. It is necessary with the implementation of the security system, it can provide a sense of security and comfort, and suppress the number of crimes that occur in the community, especially the crime of theft.

Many crimes of theft occur at home, such as theft in the garage by breaking into the garage door. Garage door means a door that is generally used for entry and exit of mounts. because security is the primary priority, usually someone will give the key to the garage door, but sometimes the key can be lost or duplicated by irresponsible parties and it is easy to break into the garage door lock. Besides security, people also want a system that is easier and easier to use the garage door. because some people are lazy to open and close the garage door especially when it rains.
