A "3 in 1" video loss detector can support different types of video signals, including:
1. Analog/CVBS video signals transmitted over coaxial cables and/or UTP.
2. High Definition (HD) video signals transmitted over coaxial cables and/or UTP.
3. Network IP (IP) camera signals.

The type of video signal supported by the 3-in-1 video loss detector depends on the specific device and its capabilities. Some devices may only support analog video signals, while others may support both analog and digital video signals. The CAN-VLD is an advanced 3-in-1 video loss detector that supports high definition CCTV signals, which provide higher video quality and resolution compared to standard definition video signals.

It's important to choose a 3-in-1 video loss detector that supports the type of video signal used in your surveillance system to ensure that the device can accurately detect video loss while monitoring the video signal.
