1. Figure 4 Principle of the Second Sight System The system which is entirely passive makes a spectral analysis of the scene at a distance using an appropriate filter set The system updates the measurement in a time less than 2 seconds The use of an infrared camera requires automatic recalibration regularly every 30 minutes This makes the system blind for a few seconds which is indicated by the system s general status indicator The head of the Second Sight detection system is entirely autonomous the portable PC is only connected to the head as a client in order to view alarms and adjust the surveillance parameters The fact that the client is connected to the head does not influence the detection system s operation 1 4 1 Autonomous Mode The autonomous mode refers to the head s operation when the client portable PC is not connected In autonomous mode the head performs the detection with the last parameters defined by the user When a detection alarm goes off the red light located on the back of the head blinks and an audible signal is made When operation is normal without alarm only the green light is on The following figure shows the position of the lights on the head 12 GENERAL MONITORS Second Sight TC Figure 5 Position of the Light Indicators on the Back 1 4 2 Remote Mode The remote mode interfaces with the detection head with the help of the portable PC in order to visualize the system stat
