The reliability of a CCTV system is influenced not only by cameras and recording devices but also by the quality of the power supply system and users’ understanding of basic installation and maintenance. This Community Service (PkM) activity aimed to improve the knowledge and practical skills of residents of RT 03 RW 12, Grogol Selatan, South Jakarta, in selecting, installing, measuring, and performing basic maintenance of CCTV power supply systems. The activity employed a participatory approach consisting of needs identification, instructional sessions, demonstrations, hands-on installation practice, mentoring, and evaluation using pre-test and post-test assessments. Ten participants consisting of neighborhood administrators, community representatives, security personnel, youth members, and residents participated in the activity. The evaluation results showed that the average pre-test score increased from 50.5 to 87.5 in the post-test, representing an increase of 37 points or 73.27% relative to the initial score. In addition to the knowledge evaluation, practical activities involved the installation and measurement of a 12 VDC power supply system on several CCTV cable runs. The test results showed an average output voltage of 12.34 VDC and an average voltage drop of 0.48%, with the highest voltage drop of 1.21% occurring at a cable length of 85 meters. All tested cameras produced clear images, and DVR recording operated normally. The results indicate an improvement in participants’ knowledge and provide practical experience in CCTV power supply installation and testing. The sustainability of the activity is supported through the assignment of maintenance responsibilities, periodic inspection of the installation, and basic troubleshooting by the community.
