Which piece of equipment can be used to capture video surveillance in conjunction with an alarm system?

CCTV cameras are specifically designed for video surveillance, making them a critical component of many alarm systems. They can record footage in real-time and can be integrated with alarm systems to provide visual verification of alarms that may be triggered by unauthorized access or other security events. This capability enhances security by not only alerting individuals of a potential break-in through the alarm system but also providing visual evidence that can be reviewed later.

In contrast, smart home monitors generally refer to devices that oversee home automation and may offer some surveillance features, but they are not primarily designed for this purpose. Heat sensors are intended to detect changes in temperature and are often used in fire alarms rather than for video monitoring, while carbon monoxide detectors serve to alert occupants to dangerous gas levels, lacking any video capabilities at all. Thus, CCTV cameras stand out as the appropriate choice for capturing video surveillance in conjunction with alarm systems.
