<![CDATA[A reliable and integrated security system is necessary to maintain the security and privacy of residents, providing a sense of security and comfort in their living environment. Threats such as theft, vandalism, and other criminal acts underscore the need for more sophisticated security solutions. A residential portal security system that uses ultrasonic sensors to detect incoming vehicles and a camera module to take a picture of the vehicle's license plate.This system is designed to increase security and efficiency in managing access to housing, as well as facilitate residents in and out of parking areas using license plate recognition technology. With this system vehicles located in residential areas tiban 1 will be safer because the portal on this system can only be open if the license plate is registered in the database and this system uses Optical Character Recognition (OCR) technology that is able to read the license plate accurately. The system works well in opening the portal automatically when a registered vehicle is detected. This process takes about 10 seconds from the recording of the license plate until the command to open the portal is sent to the servo motor. From the tests carried out, the system managed to recognize 9 out of 10 vehicle license plates with an accuracy rate of 90%. This shows that the license plate recognition technology used in this system, which involves the ESP8266 camera and microcontroller, works very effectively and efficiently.]]>
