This is a indoor/outdoor bell or just indoor?

This is plugged directly into a phone jack which would limit its range. However it has a wide variety of tones and volume options making it perfect for the hard of hearing. I highly recommend it.

I'm sorry I was unclear, you would need to attach a long line cord and put the amplifier in a window or doorway to be heard outside. It needs to be plugged into a wall socket and phone jack. It is not battery operated.

There is a metal plate that a hammer strikes against, so it's not electronic. However, it is just one note, and not two. Like "Ding!", not "Ding Dong!" I think the "Dong!" is saved for the back doorbell; if you have two doorbells, this one will hook up to both. Bit disappointing, but it does look really nice on the wall.

This bell is triggered by a rubber hose being run over. You are limited by the length of the hose. I suggest the Dakota Alert system. It is more money but can be heard up to a larger distance because of its remote receiver.

It's wired in parallel with the bell. See this: http://www.youtube.com/watch?v=eSOvGjyhaLE

The bell that rings inside the home is 4" x 6". The push button that mounts outside the door is about 1" x 3". Excellent bell and very appropriate sizing.

It's a indoor. My son only uses it inside and he hasn't mentioned any minor flaws yet. However, my son and his grandpa likes to tinker with helicopters so they may have supped it up to work for them.

This only has one bell unit(the small blue box), and the other two are receivers to the chime. You can install those anywhere in the house. I'm not sure if you can buy two sets and use two bells for the same receivers. That may be the option.

The Motion Detector is a separate item. The bell has an outside button and you can place the bell within 33 feet of the doorbell part. You can also adjust the sound which is good.

This bell works fine for me, in a 1000 square foot store and into the back room with the door open, but I would not depend on hearing it on a second floor, particularly if there were any doors between the listener and the bell. I hope that was helpful for you.

No. This unit is designed for outside. It would be too sensitive for indoor use

There is no speaker for the video or anything. For the doorbell, it's quite loud. I actually requested people use that bell b/c it was louder than our builder-grade doorbell. BUT, we've had it for less than a year and the doorbell stopped working all together.

It is labelled for both. For indoor use. It is of average quality compared to other indoor balls. It is above average quality for outdoor use. In my opinion, the price is not justified for use outdoors.

I really don't know as I haven't had it indoors....it didn't move around too much, and didn't seem to be too loud, but there is a big difference when something is outside vs inside.

The bell will NOT work if it is mounted vertically! The swinging weighted piece inside the bell is what allows the "button" on the top to stay lifted. When it is on a wall, the weight doesn't keep the "button" up, so when you push on it, there is no movement and no sound!

No it's not, it's a one way unit. It has to different ringers, one is like a door bell and the other is like a alarm.

The ringer is definitely a bell. It's a REALLY LOUD bell. The nice thing is that there's a small lever on the bottom of the phone which adjusts the strength of the bell from no sound to a deafening roar that would wake the dead.

This one is indoor only, but there is another PetSafe Bark Control that's for outdoor use. Hope this helps.
