Difference Points |
First - generation Water Monitor |
Third - generation Water Monitor |
Positioning Method |
Cross - shaped narrow - slit technology |
Infrared thermal imaging array temperature - measuring technology |
Sensor |
Two - point detection with a narrow range |
One - surface detection with a wide range |
Positioning Basis |
Whether there is firelight in the horizontal and vertical slits |
Real - time temperature of each pixel point |
Positioning Error |
With errors |
Without errors |
Reliability |
Prone to false spraying |
Double - insurance, no false spraying |
Operation Mode |
Button - type |
Liquid crystal color touch screen |
Moving Fire Source Tracking |
Only positioning, no tracking |
Real - time tracking once a fire source is detected |
Application Scenarios |
Places with low reliability requirements |
Places with high - precision and high - requirement |
Linkage of Water Monitors in the Same Area |
No linkage |
One early - warning activates the overall linkage scan |
Water Monitor Control System |
Single manual - automatic conversion |
Time - segmented manual - automatic conversion, more user - friendly |
Wiper |
None |
The large monitor can be optionally equipped with a wiper positioning sensor, and the camera can be self - cleaned |
Monitor Number Groove |
None |
Yes |
Monitor Barrel Length |
Long, the rotation radius is longer than the monitor body, easy to hit the wall |
Short, the barrel is as long as the monitor body, no wall - collision during rotation |
Monitor Body Sealing |
Unsealed |
Fully - sealed, waterproof and dust - proof |
Wiring |
Wiring rotates with the monitor body, easy to get entangled (may cause wire breakage) |
Wiring is fixed, no entanglement |
Built - in Valve |
None |
Optional electric valve, the electric valve is the most reliable, can close automatically when power - off |
Built - in Filter |
None |
Yes, the middle is higher than the outer ring, debris collects towards the outer ring |
