Would you like to do more with your security camera or DVR system? If your security camera system's Pan/Tilt/Zoom (PTZ) capability uses RS485 and the Pelco-D or Pelco-P standard, then this kit could help provide up to 6 relay outputs with your current system. This kit acts as an interface between your camera system and other things you want to control, like playing a recorded message, turning on a light or controlling motors, you decide.
The unit can be set to a possible 255 address combinations, so multiple units can be used together. Each relay output can switch a maximum 500mA load and provides a visible red LED indicator. The outputs can be configured to operate as momentary or latching outputs.
