Built-in Mic CCTV Camera Aur Audio Recording: Karachi Ke Gharon Aur Offices Ke Liye Guide

Audio over Coaxial (AoC) aur IP Built-in Mic Technology Kya Hai?

Iska matlab yeh hai ke video signal, audio signal aur power sab ek hi standard coaxial cable (RG59) ya CAT6 cable (video balun ke sath) par travel karte hain.
