Notes to use WV-SUD638 in cold climates

  • Snow may adhere to the glass surface in cold climates.
     Please remove snow regularly with a wiper.
  • When using in cold climate, we recommend using AC power supply.
     In the case of designated PoE injector, the heater on the glass surface does not operate if IR-LED were ON due to limitation of the supplyable electric power, and snow tends to adhere to the glass surface.
Models Power Sources Operating temperature ranges Remarks

(At power on: -30 deg.C to +60 deg.C) *1
When snow falls in the strong wind, snow accumulated thickly on the glass surface may not melt, and/or the wiper may freeze and stop working.
