It’s common to see some electronic devices mounted on different positions in different
places we go, they are called CCTV cameras. CCTV cameras are used for surveillance to
ensure the security of people and properties. The need for security cannot be overemphasized in today’s world, and thanks to technology, CCTV cameras give the privilege of ensuring security through video recordings of happenings even when one is absent.
WHAT ARE CCTV CAMERAS?
CCTV cameras otherwise called closed-circuit television cameras in full are gadgets thatrecord video footages and get them transmitted. There are different types of CCTV cameras, but CCTV cameras can be classified into two: Analog CCTV cameras and IP CCTV cameras.
CCTV camera was invented by Walter Bruch a German engineer in 1942. The first CCTV
was used to monitor the launch of a rocket. It is also reported that the Singapore airport with 3000 CCTV cameras has the world’s largest CCTV system.
IP CCTV VS ANALOG CCTV.
Analog CCTV cameras are types of cameras that record videos and transmit the signals to a digital video recorder (DVR). The DVR converts the signals from analog signals to digital
signals. The video can then be stored and viewed through monitors that are connected to the DVR.
IP CCTV cameras are surveillance cameras that record videos digitally and then the videos
are transmitted and viewed over the internet. IP cameras need a Network Video Recorder
The choice of whether to use a digital or an IP camera will depend on your choice
considering the various differences they have.
- To start with, IP cameras tend to be more expensive than the analog cameras.
- The fact that analog cameras have been around before their digital counterparts, makes
it easier to find an installer.
- Analog cameras are easier to set up.
- One edge that digital CCTV cameras have over analog cameras is video quality.
Digital cameras are good for areas with much movement because they produce images
that are sharper than analog CCTV cameras.
- Video recorded via IP cameras can be encrypted thus enhancing more security.
