When installing ANPR cameras it is important to consider both the mounting height and angle of the camera. If the camera is mounted too high or the horizontal/vertical angle too great, then the accuracy of the recognition software will be diminished.
Listed below are the recommended mounting height and angles for reference.
When configuring the ANPR camera for use with an NVR or as a standalone system, all devices should first be connected together. The ITC237-PU1A-IRHL supports POE (802.3at) or can be powered by 12v DC
12v: Used when not utilizing the PoE capability, connect the 12v positive to this terminal and link to terminals on the camera body
GND: This is the terminal used for the negative connection when using 12v power
LAN: Connection to Network switch or NVR PoE port
POE: PoE connection to body camera
Reset: Push button used to restore camera to factory settings
G: Ground connection for alarm inputs
L1/L2: Alarm Inputs 1 & 2, used to trigger snapshot independently
NO: Normally Open alarm output connection, used to trigger external devices such as barriers
C: Common terminal to be used with NO terminal
Once the camera has been mounted and all connections terminated, use a PC or Laptop connected to the same network switch as the ANPR to login to the web browser interface. By default the IP address of the camera is 192.168.1.108, if required this can be changed via the Config Tool or within the camera web browser.
Login to the camera via the computers web browser. Username: admin Password: admin123
NOTE: When connecting to an NVR it is vital to use the correct login credentials in the NVR remote device menu. Failure to input the correct credentials will lock the camera until the correct credentials are used and the camera is rebooted.
Once logged into the camera the live display will be shown.
