Procedure

CCTV is a state-of-the-art technology surveillance system, an eye on complete organisation. This can be most
gainfully utilized to achieve optimum security level. The idea of CCTV is to ensure safety & security by surveillance.
It creates a safe and secure environment by ensuring the following:
a Detecting offenders and preventing crimes, theft, sabotage, burglary within the facility.
b Providing evidence for any investigation and offender’s prosecution.

c Preventing and responding effectively to any crises and harassment of any kind
d Enhancing confidence and commitment to the security of premises.
A CCTV camera system makes use of video cameras, also called surveillance cameras to keep track of the
interior and exterior of a property, transmit the signal to a monitor or set of monitors, and give real-time 24/7
viewing access.
With all these benefits, a surveillance system has become a must in a society where there is an increase in
the crime rate. So, when you decide which security system is best for your unique necessities, these are the 5
essential components you should give importance to:

Basic principle of CCTV:
CCTV systems work based on capturing a sequence of images and displaying them as Real-time videos. The two
types of CCTV systems are wired and wireless systems. Wireless systems work on the concept of connecting to
a signal hub connection and giving you 24/7 viewing.
1 Camera:
If you’re building a CCTV Camera System, you have two camera options: Internet Protocol (IP) or analog. IP is
usually the preferred choice due to its compatibility with most devices. Many different types of cameras can be
installed, for example -dome cameras, bullet cameras, covert cameras.
Depending on how many angles you want to cover, how many cameras you will need in that specific area, how
much resolution or detailing you require when you choose your preferred cameras.
Type of cctv camera:
Dome CCTV Cameras
PTZ Pan Tilt & Zoom Cameras

Bullet CCTV Cameras
