Do I need to purchase 2 AC adapters, one for each of the two units? Will the voice activation pick up traffic noise as we live on a busy road.

You will need to buy two adapters yes I put in batteries and they do not last at all. It works like a Wilkie talkie I don't hear noise or other talk. I don't believe it will pickup traffic noise I do not know live near busy street though.

You will need 1 adapter per unit. They pick up a lot of noise from the surrounding area. The voice was overridden by the hospital bed's air pump, which was isolated to a point, that you could hardly hear it with your ears. Save your money.

As a backup... It doesn't need them as long as the power doesn't go out! I connected mine directly to the phone line. It is loud great product!

Hi Gail...I can't tell you what it takes for the car. I never used it in the car yet. I believe the unit came with what was needed for the car if you just wanted to use the FM radio and dial in the unused frequency. However, if you wanted to tap into the radio's antenna for a more direct route you would have to buy an adapter. I DO use it in my office. I purchased an adaptive cradle with a 12v power adapter and another antennae for ~ $30 - $40. The cradle allows you to use any speaker system that you would use with your computer...3.5 mm plug. Antennae just sits in my window and it works well. You must have access to the sky where the satellite is though. Hi Gail...I can't tell you what it takes for the car. I never used it in the car yet.

I have used up to 3. You are limited by the tower you are talking to, not the amplifier, and the way you access the signal (mine is a small pad I attach to the phone). I drove truck and had a whole cab hot spot that worked well. Data, phone, etc.

Provided you set up the color-coded frequency (very easy process) to do so, yes. I did too, for a time; however, it didn't really work all that well for me. I have 2 young children; a baby and a 5yr old who sleepwalks. If I heard a noise I didn't like that wasn't a voice, I had to check both rooms, possibly not getting where I was needed as quick as I'd like. Since you'll be getting 2 receivers anyway you might wanna give them different frequencies.

I have not had any complaint, but I will close my windows or turn down the AC fan during a call. The main reason for that is I have to turn down the volume on my radio. Incoming calls come in much louder than what I am listening to. My speakers are not the best, worn OEM speakers, they get over driven easily. I have the mic/button mounted on my rear view mirror and it works great.

The units comes with an alarm, which I believe is powered by straight 12V, but it is not a speaker. Audio speakers have specific impedance and voltage limits. I wouldn't risk damage to a vehicle audio system by wiring the alarm's 12v supply direct to your car's speakers. The alarm is quite loud by itself. You'll hear it. Put it this way, if you are listening to speakers or headphones so loudly, that you cant hear this alarm, you're a hazard to yourself and others on the road.

I only use the device in the car driving back and forth to work so there is not alot of noise to start with. I would pay the extra because I can here better when using the device.

I think it will work. It plays whatever you record every time the motion sensor is triggered and it's fairly loud. I don't think interference is a problem bc it works on motion, so if you're not walking past both at the same time only 1 will trigger. You do have to buy a card thingie to load the sound. Another $15.

Can I purchase 2 units run work off the same amplifier so I can have 4 devices auto connect? Also how does it know which device to play first?

NO!, but it will enhanced the signal. I have both, one for the house and the other for the car.

This isn't the right adapter for your car. Audio quality is pretty good (if it works) . But in some vehicles if you're charging a device from your 12v socket and playing music from the same device you'll get a steady whine. To fix that you'd need to install a ground loop isolator.

Separate A/C adapter.I'm starting to really like these speakers.Just don't turn them up too loud.I think they'd probably blow...

This just comes with the car adapter. You might be able to purchase another cord, but probably not worth it. I would look for other ones that are dual power.

I don't think that should be a problem. I've attached multiple devices (e.g., PC, fax, phone, etc.) to one phone line. The only catch might be that if there is a power loss or low temperature then both might be effected and will try and call out at the same time.

I just the adapter in each unit.. But I found that if I turned my rear wireless speakers on I had issues. Turned the rear speakers off and all worked well!

yes it will automatically find the weather alert channels in the area you are driving in or through but and this is a big but the batteries will die very quickly so you will need a huge supply of rechargeable batteries. The AC adapter does not work. I have had two AC adapters but both stopped working. So if you plan on keeping it on constantly then the batteries will die after about 12 hours of use.
