What is Analog , AHD, CVI, TVI & IP based CCTV systems ?

I recently had to go for cctv installation sydney and it was the best decision. I had long heard that UVS Group were the best specialists in this field, so I turned to them for their solar and wired CCTV systems. The solar-powered cameras have proved particularly useful for remote sites where a network connection is not always possible. This has allowed me to secure even the most inaccessible locations.I can now monitor my facilities in real time from anywhere, which gives me added peace of mind. I highly recommend UVS Group to anyone looking for reliable and modern video surveillance solutions.
