Inputs/Outputs For Video Surveillance Guide

Author: IPVM Team, Published on Aug 24, 2018

While many cameras have Input/Output (I/O) ports, few are actually used and most designers do not even consider them. However, a good understanding of their flexibility can save hundreds of dollars on complex designs.

In this guide, we explain camera I/O and how it can be used to integrate devices and functions not supported out of the box in surveillance. Inside, we cover:

  • Input/output basics
  • I/O styles (on board vs. whip vs. removable)
  • I/O equipment: Cameras, modules, recorders
  • Common applications for inputs
  • Common applications for outputs
  • Form factor differences
  • VMS integration issues
  • ONVIF support issues
  • Camera capabilities vary widely
  • VMS multi-camera I/O integration
  • VMS support variance
  • I/O troubleshooting drawbacks
