WHAT IS CCTV AND HOW DOES IT WORK?

CCTV (closed-circuit television) is a video surveillance system that uses cameras to transmit a signal to a specific, limited set of monitors. The cameras are typically mounted in strategic locations and are connected to a series of monitors or a recording device.

CCTV cameras can be used for a variety of purposes, such as security, monitoring activities in a specific area, or for investigative purposes. They can be used in both residential and commercial settings and can be either wired or wireless.

CCTV systems can be monitored in real-time or the footage can be recorded for later review. The footage can be accessed through a monitor or a device such as a smartphone or tablet, depending on the specific system.

CCTV is a useful tool for providing surveillance and security for a specific area or property.

WHAT ARE THE DIFFERENT TYPES OF CCTV CAMERAS AND WHICH ONE IS BEST FOR MY HOME?

There are several different types of CCTV cameras to choose from, and the best one for your home will depend on your specific needs and budget. Here are a few common types of CCTV cameras:

Dome cameras: These cameras are mounted on a dome-shaped housing, which makes it difficult to tell which direction the camera is facing. They are often used in retail environments, as they can be mounted on the ceiling and are less noticeable than other types of cameras.
Bullet cameras: These cameras are cylindrical in shape and are typically mounted on a wall or ceiling. They are named after their shape, which resembles a bullet.
PTZ cameras: PTZ (pan, tilt, and zoom) cameras can be controlled remotely to pan, tilt, and zoom in on specific areas. They are often used in larger properties or in environments where it is not practical to have a person physically moving the camera.
Hidden cameras: Hidden cameras are designed to be covert and can be disguised as everyday objects such as smoke detectors or clocks. They are often used for undercover surveillance or to monitor activities in a specific area without being noticed.

To determine the best CCTV cameras for your home, consider the location where you want to install the cameras, the field of view you need, the resolution you require, whether you need night vision capabilities, and whether you want wired or wireless cameras. It may also be helpful to consider your budget and any specific features you need, such as weather resistance or the ability to pan and tilt.

HOW DO I CHOOSE THE RIGHT CCTV CAMERAS FOR MY HOME?

There are several factors to consider when choosing CCTV cameras for your home. Here are a few things to consider:

Location: Consider where you want to install the cameras and what you want to capture. This will help you determine the type and number of cameras you need.
