Both offer distinct advantages and serve as deterrents to potential intruders, but understanding the differences between them is crucial in making an informed decision about which option best suits your needs.

CCTV Cameras: Keeping an Eye on Things

Understanding CCTV (Closed-Circuit Television) cameras is essential for anyone interested in enhancing security or surveillance measures for their property or business. CCTV cameras play a crucial role in deterring criminal activity, monitoring premises, and providing valuable evidence in the event of incidents. Here’s a comprehensive guide to understanding CCTV cameras:

1. What are CCTV Cameras

CCTV cameras are surveillance cameras designed to capture video footage of specific areas or activities.
