SierraTeck Motion Activated Sound Player

Works great! Comes with a few pre programed sounds.

Our unit worked just great for a month until the battery ran out, and then it didn't seem to recharge. Customer service was easy to contact, responded promptly, and immediately shipped a new unit out to me. After getting the new unit, I discovered that the problem wasn't with the device at all, but just a corrupted SD card. Conclusions: 1. If you have ANY problem whatsoever, including an apparent dead battery (no lights or sound even when pushing the buttons), try removing the SD card if installed. Some card faults just lock up the device, but it will work fine with no card installed (using the default sounds) or with a new card. 2. Even if that's not the issue, SierraTeck will have your back. I've had bad experiences with customer support from other small electronics brands, but these guys were great, following up with the support request even over a weekend. I would buy with confidence from them again. (I'm not in any way affiliated with them, just impressed.) The device itself was perfect for what I wanted--- just save .mp3 or .wav files on a memory card, and set it to either play them at random, step through in sequence (one file per motion activation event), or always play a particular file (until you select a different one). The max volume is VERY loud (but easily adjustable with a dial on the unit), motion detection works well, and you can swivel the device 360 degrees around its mounting post to aim the detector wherever you want.

As described. Only four stars because I had to choose between having a microphone to record messages, but battery powered vs. No microphone but plugged in outlet, which means downloading mp4 to mp3 convert app. I don't remember that being mentioned anywhere, so that was irksome. This was the most reasonably priced with good reviews I could find. I would've paid a little more for a microphone AND outlet option. But, this works well, is easy to operate and set up. Received several months ago and has been very reliable.

Awesome! Seriously, I've been looking for one of these. Ones that would do what I wanted run around $400, or you can build one yourself... yeah, not gonna happen. How I Use This: I wanted music when I walk in the door of my home. Nice, classical guitar, etc. One song to softly play and then quit. I've set this one up with about 15 songs to randomly rotate through on the supplied memory card. I walk in the door, it triggers and begins to softly play. I've got it positioned so it just triggers when somebody moves through the front door. The perfect way to come home! I love this thing. Also, I will be putting my home on the market in the spring. How cool is that for clients seeing the home? Want to impress folks with your "Smart," Wire-free home? This is the perfect addition.

This repeater is awesome. I am using it for a info message in a historic home with no power. The little speaker does an amazing job and can easily be heard from across the room. The motion sensor works like a dream. The internal battery operates the repeater for a full 8 hours. Can easily work more hours when hooked up to a power pack battery (like for a phone). The internal memory holds 3 minutes but the included micro SD card holds up to 8 Gigs of audio (huge). Bought this one to test out and I will ABSOLUTELY be purchasing more. I cannot believe the high quality for so little money. EXCELLENT! I think this would also be amazing for people living with Alzheimers to remind them to "stay safe in the house, you have Alzheimers" or "don't dress for bed yet, you have company coming" or "this is your house and everyone in here is your family and friends and they all love you".

I don’t know how the motion detection or sound quality is (all I heard was a gravelly growl when I turned it on). But, it’s a complete non-starter for me. Sorry, but the incompatibility with Apple OS/iOS is just lame in this day and age of cross-platform development standards.

Loaded it up with a massive playlist. It only plays like 3 of the songs... the same ones. I have to push the "A" button for it to ACTUALLY select a random-seeming song. The problem is that I have to do this every. single. time. All the filenames are completely generic, so it’s not some encoding issue. Please fix your randomization algorithm.

My primary use for this device is for holiday greetings at my front door. Updating the messages is simple enough, just copy MP3 files to the included SD card and put in the device. It has a battery pack in it that allows for it to playback without any wired connections. Not sure how long a charge would last if there is heavy traffic. It comes with a charger and cable that can be plugged in while it is installed, eliminating the concern about battery life. The volume is very good, loud!. Sound loudness can be adjusted with a thumb-wheel. The unit feels a bit cheaply made, especially given the price, but so far it performs well and is exactly what I wanted.
