security systems in visakhapatnam


CCTV provides remote electronic surveillance of prime target areas throughout
your premises. Permanent 24-hours security protection, with no staff overheads.
As a powerful tool for the security guards, often reducing their numbers, CCTV
systems provide greater security cover. CCTV systems have a powerful deterrence
capability and provide extensive data of recorded images for post event
analysis.

                           Types of cctv camera

  1. Analog

    2.ip cameras

     
    THE MAIN DIFFERENCE 
     
    The signals that an analog sends out are from made up of lines that don’t transfer well onto a
    screen. The line become overlapped when scanning, and ends up looking smudged and blurry
    when viewing the image on a TV or even a PC. It’s true that
    an analog will be cheaper to set
    up, but the quality is lost, and that’s something
    that one doesn’t need for any type of security
    uses.
    An Ethernet cable connection for an IP is better too when compared to an analog system. Since
    the computers that run your security have a protocol in place that means that other computers
    online for security can in effect read each other.
    You’ll not loose captures, and if you ever loose
    power the main control in the
    security operator’s area will power the computers to keep
    running.
