SENSOR
Sensor In : Connect the sensors. The sensor are composed of both signal and ground
terminals, with a voltage difference of 5V. In the case that the sensor used for input
is of the N/O (Normal Open) type, when the voltage difference between the signal
and ground falls to 0V (short), the DVR can use this as a trigger to start alarm/sensor
based recording.
Sensor Out : Connecting external electrical devices
The 1 output sensor terminal does not provide power, and functions only on an
ON/OFF basis via a relay. Normally, the signal and ground should be on an OPEN
basis, and the DVR will complete the relay connection.
3) Connecting with PC using LAN cable
If you want to connect DVR to PC directly, use Cross Cable(1), and if you want to
use HUB, use Direct Cable(2).
*Hub : This is a device connecting one office to devices located near with using
cable when you organize LAN
*Direct Cable : This is standard UTP cable used for communication among
devices through Hub and others when you organize LAN
*Cross Cable : This is a cable that has changed internal array of standard UTP
Cable for direct communication among devices not using connection
devices like Hub when you organize LAN
