Overall, the primary purpose of surveillance cameras is to provide a visual record of events, which can be used to improve safety, prevent crime, and enhance overall security.
How do surveillance cameras work?
Surveillance cameras work by capturing video and audio footage through a lens and sensor, which is then transmitted to a recording device or monitored in real-time. The camera’s sensor converts the light and sound into electrical signals, which are then processed and stored on a digital video recorder (DVR) or network video recorder (NVR). Some surveillance cameras also have additional features such as motion detection, night vision, and weather resistance.
The footage captured by surveillance cameras can be viewed in real-time or recorded for later review. Many modern surveillance cameras also have the ability to stream footage over the internet, allowing users to access and view the footage remotely using a smartphone or computer. This can be especially useful for business owners or homeowners who want to keep an eye on their property from a remote location.
What types of surveillance cameras are available?
There are several types of surveillance cameras available, including dome cameras, bullet cameras, PTZ (pan-tilt-zoom) cameras, and IP cameras. Dome cameras are typically used indoors and have a dome-shaped casing that makes them difficult to tamper with. Bullet cameras are long and cylindrical in shape and are often used outdoors. PTZ cameras can be controlled remotely to pan, tilt, and zoom in on specific areas.
IP cameras, on the other hand, are internet protocol cameras that can be connected to a network and accessed remotely. They often have additional features such as motion detection and night vision. Other types of surveillance cameras include wireless cameras, hidden cameras, and thermal cameras. Each type of camera has its own unique features and benefits, and the right type of camera will depend on the specific application and needs of the user.
