These adapters come in a variety of forms such as BNC connector or VGA/DVI. These types of transmitters are available in either active or passive models. Active transmitters require a power source, whereas passive transmitters do not need power. There are many models with a variety of features to choose from depending on your security system needs. You can purchase a single connection receiver or connect an 8-channel hub to your system to balance out your video signals throughout your entire system.
