Closed-circuit television (CCTV) is a surveillance system that uses video cameras to transmit signals to a specific set of monitors or recording devices. It allows users to monitor and record activities in specific areas for security purposes.

CCTV systems consist of cameras, a recording device such as a digital video recorder (DVR) or a network video recorder (NVR), and a monitor for live viewing. The cameras capture video footage, which is then transmitted to the recording device for storage or live viewing on the monitor.

Having a CCTV system offers numerous benefits, including: – Enhanced security and crime deterrence. – Surveillance and monitoring of critical areas in real-time. – Evidence gathering for investigations. – Remote viewing capabilities through mobile devices or computers. – Peace of mind for homeowners and business owners.

There are various types of CCTV cameras designed for different surveillance needs, including: – Dome cameras: Suitable for indoor and outdoor use, with a vandal-resistant design. – Bullet cameras: Ideal for outdoor monitoring with long-range and weatherproof capabilities. – PTZ cameras: Pan-tilt-zoom cameras that can be remotely controlled to change the direction and zoom level. – Thermal cameras: Detects heat signatures and is useful for low visibility conditions. – Hidden cameras: Discreet cameras that can be placed inside objects or disguised as other items

An alarm system is a security device that detects intrusions, unauthorized access, fire, or other emergency events. It triggers an audible and/or visual alarm to alert individuals of the potential threat or emergency situation.

Alarm systems typically consist of sensors, a control panel, and a communication method. The sensors detect specific events or conditions, such as motion, door/window openings, smoke, or heat. When a sensor is triggered, it sends a signal to the control panel, which then activates the alarm and, if applicable, notifies a monitoring center or designated individuals.

There are various types of alarm systems, including: – Intrusion alarms: These detect unauthorized access or intrusion attempts. – Fire alarms: They detect smoke, heat, or fire-related events. – Carbon monoxide alarms: They monitor and detect the presence of carbon monoxide gas. – Panic alarms: These are used in emergency situations to alert for immediate assistance. – Environmental alarms: They monitor environmental factors such as temperature, humidity, or water leaks.

The length of time CCTV footage is stored depends on various factors, such as the capacity of the recording device and the settings configured. It can range from a few days to several months, depending on the requirements and storage capacity of the system.

Most modern CCTV systems offer remote viewing capabilities through mobile apps or computer software. By connecting your device to the internet and accessing the appropriate app or software, you can view live video feeds or playback recorded footage remotely
