DETEXI NVR 46 - 169
Integration
1. Network Camera Input and Output Ports
A unique feature to network cameras and video encoders, in comparison with
analog cameras, is their integrated input and output (I/O) ports. These ports
enable a network video product to connect to external devices and enable the
devices to be manageable over a network. The range of devices that can connect
to a network video product’s input port is almost infinite. The basic rule is that any
device that can toggle between an open and closed circuit can be connected to a
network camera or a video encoder. The main function of a network video
product’s output port is to trigger external devices, either automatically or by
remote control from an operator or a software application.
The DETEXI NVR can be easily integrated with different mechanical and
electronic security devices. For example, the DETEXI NVR can be instructed to
receive video only when the sensor triggers; or a network camera or video
encoder connected to an external alarm sensor via its input port can be instructed
to FTP video out to the DETEXI NVR FTP Server.
9 Network camera or video encoder inputs/outputs must be defined in the NVR Control Center —
Cameras — Cameras Settings for the NVR to be aware of external devices connected to the IP
device inputs/outputs.
Examples of External Devices That Can Be Connected To the Camera INPUT Port
Device Type Description Usage
Door contact Simple magnetic switch that detects
the opening of doors or windows
When the circuit is broken (door is opened),
the NVR can take action by sending full-
motion video and notifications
Passive infrared detector (PIR) A sensor that detects motion based on
heat emission
When motion is detected, the PIR breaks
the circuit and the NVR can take action by
sending full-motion video and notifications
Glass break detector An active sensor that measures air
pressure in a room and detects sudden
pressure drops (the sensor can be
powered by the camera)
When an air pressure drop is detected, the
detector breaks the circuit and the NVR can
take action by sending full-motion video and
notifications
