Security is essential in our daily lives, whether in a personal, home, business, or industrial setting. As a result, to ensure high security, a complicated surveillance system is required. This is typically not cost effective, necessitates more consumable electronic devices, requires more maintenance, and needs more storage space in settings. Hence, the goal of this research is to create a single, small, and simple IOT-based smart closed-circuit television (CCTV) control system. A low-cost smart security system can well be built using the Raspberry Pi microprocessor. The components involve are a camera, a sensor, and a Raspberry Pi board. The proposed smart surveillance system creates a comfortable and safe environment for households to initiate immediate recording of the surrounding upon triggering of sensors assemble at the specific entrance or exit points at home. Raspberry Pi microprocessor is used to be integrated with closed-circuit surveillance camera with motion detection, allowing smart automation of home surveillance system at a cost-effective manner. When the Raspberry Pi is connected to the Internet, the user may even remotely turn on or off the CCTV using the smartphone application. The system was tested with movement at the sensor from a range of distances based on the location setting. It can deliver the anticipated output such as alarm triggering, automated initiating recording of surrounding from the CCTV camera, sending an alert notification to the user's mobile phone, allowing monitoring of the location setting through the user's device, as well as turning off the CCTV camera through the user's device via the developed system.
Security plays an important role in our everyday lives be it in a personal, residential, commercial or enterprise setting. In the traditional home security setting, user can retrieve the video captured from the closed-circuit television (CCTV) when needed. However, user will not be notified when there is intruder. This disadvantage can be overcome by inculcating the idea of Internet of Things (IoT) into home security system. Smart home security system can integrate various types of sensors such as motion sensor, humidity sensor and temperature sensor together with electrical appliances in house such as CCTV camera, lights and fans. Smart home security system is capable to send notification to alert user if detected any house scenario which is abnormal so that user can act immediately upon receiving the notification for appropriate action. This helps to ensure the security of house. There are various home security systems proposed by past researchers. Therefore, this paper aims to provide a comprehensive review on the proposed designs and to analyse and compare the results to determine the challenges and prospect in this field of technology.
