Alarms By Hilitand

• AUTOMATIC RECOGNITION This counter window microphone adopts two-way voice intercom communication technology, which automatically recognizes and processes the voice stack number, and does not require any operation during the call.
• AUTOMATIC SQUELCH - This window intercom system adopts a side tone cancellation processing chip, which has an automatic noise suppression function, which can effectively improve howling. Two-channel adjustment, with dynamic channel indicator, more convenient to use.
• TWO WAY SOUND SIGNAL: It can output internal and external two-way sound signals (with the bank counter recording), using the stereo plug output method, and the recording function is not controlled by the power switch and each function button.
• EASY TO INSTALL - This window speaker adopts automatic call control technology. The microphone and speaker of the external unit are designed integrally and connected to the host by a line, which is easy to install. The auxiliary furniture can be hung on the wall or attached to the glass with the supplied double-sided tape.
• SUPPORT VOLUME ADJUSTMENT: The inner volume knob and the outer volume knob can adjust the inside and outside volume respectively. During the intercom, the two green indicator lights at the top of the IN controller indicate that the host is talking and OUT is bright, indicating that the secondary machine is talking.
