Upgrade your existing system to high definition without the need of running new cables.

Available high definition over coax technologies include: 

• AHD (Analog High Definition) 
• HD-CVI (Composite Video Interface)
• HD-SDI (Serial Digital Interface)
• HD-TVI (Transport Video Interface) 

Even though high definition over coax does not provide the true digital high definition as an IP camera system. But such a system can overall save you money by using your existing cable reducing the labor cost.
