Is the sound clear on this window intercom? Is there any feedback? How does it perform in noisy environments?

The Retevis RT-9908 window speaker features a dedicated sidetone processing chip, delivering true, distortion-free, clear audio. It uses a high-strength 4-core aluminum foil shielded cable to automatically eliminate noise in noisy environments.

How to install this business intercom system? Does it require drilling?

No, this window speaker intercom system doesn't require drilling. You just need to tape the speaker to the glass, and it's very secure.

In what scenarios are this window microphone and speaker suitable?

The Retevis RT-9908 window intercom system is suitable for a variety of scenarios: hospital, pharmacy, bank, counter, hotel, restaurant, food cart, ticket window, drive-thru, office, school, shop, factory etc.

How does this drive-thru intercom system work? Do I need to press a button to speak, or is it automatically hands-free?

Simply plug the speaker cable into the main unit and turn it on; the window intercom uses automatic two-way communication technology; once turned on, it will automatically detect the voice signal and communication can begin immediately.

How long is the external speaker connection cable? Can a longer extension cable be used?

The speaker cable is 7.36 inches long, which is sufficient for everyday window work. If a longer cable is needed, please take a look at our other window intercom: the TW102, which has an 8m speaker cable.

3/4 work perfect and have been working perfect since day one

ordered 4 of them for a Money wiring check cashing store, 3/4 work perfect and have been working perfect since day one. the few problems i have experienced just like anyone else is because they are not plugged in Fully/correctly.. off replug, on again and bam perfect. one of the four was defective the power adapter buzzes loudly when plugged in to ANY outlet and its microphone/speaker (circular one) hisses when plugged into any of the four i bought . thanks to amazons great return policy for defective items exchanging for a new one wont be a problem. there is no risk if you get a bad one like with anything on amazon. don't be discouraged by anyone else comments i have had loud power drills and other construction going on and these intercoms are loud enough.

El material muy corriente, las perillas quizá se barran porque se sienten algo flojas, la bocina suena muy distorsionado y si subes un poco más de la mitad el volumen se satura. Pero en general, para lo que cuesta, no creo que haya otro mejor
