A home security system and a CCTV system serve different purposes (though a home security system would typically include CCTVs), and the choice between them depends on your specific needs and preferences.
A home security system offers proactive security measures. It includes components like door/window sensors, motion detectors, alarms, and access control, providing comprehensive protection for your home. With ongoing monitoring services, the system actively monitors your home for intrusions and triggers immediate responses. However, it does come with monthly costs for the monitoring service.
On the other hand, a CCTV system focuses on video surveillance. It captures footage that can be reviewed after an incident occurs, making it more reactive in nature. While it lacks the proactive features of a security system, it can still serve as a deterrent and provide valuable evidence.
