What types of security cameras are available in the market?
There are several types of security cameras available in the market, including dome cameras, bullet cameras, PTZ (Pan-Tilt-Zoom) cameras, box cameras, and hidden cameras. Dome cameras are ideal for indoor use and are known for their discreet design. Bullet cameras, on the other hand, are suitable for outdoor use and are known for their weather-resistant design.
PTZ cameras are ideal for areas that require a wide range of coverage, as they can be controlled remotely to pan, tilt, and zoom. Box cameras are highly customizable and can be used for both indoor and outdoor applications. Hidden cameras are designed to be discreet and can be used in areas where a visible camera may not be desirable.
What is the difference between wired and wireless security cameras?
Wired security cameras are connected to a power source and a monitoring system through cables, whereas wireless security cameras are battery-powered and transmit video signals wirelessly to a receiver. Wired cameras are generally more reliable and provide a more stable connection, but they can be more difficult to install.
