Review: Installed above entry door - Works great! Comes with a few pre programed sounds.
Review: Fantastic customer service (T/S tip: remove the SD card if you have ANY problems) - 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.

## Questions & Answers

**Q: Can it sense movement thru a window?**
A: The unit senses motion that are in it's direct line of sight. If there's obstacles in the way, it won't detect motion

**Q: Does it has rechargeable battery inside the unit or have to be connected to power to operate?**
A: Removable rechargeable battery comes with the unit. Just plug it into the charger and off you go. Charge lasts very long time. The unit can be really loud as long as the sounds on the included 128 Mb micro sd card are recorded at maximum loudness.

**Q: Will this take a microSD card bigger than 128mb?**
A: Yes, it will. While the device supports up to 32 GB cards, we don't recommend using a card larger than 8 GB, as may cause some delay between motion detection and audio playback

**Q: Where is this product manufactured - USA or other?**
A: Like just about everything except cars and fresh produce... it's made in China.

### ⭐⭐⭐⭐ This was the most reasonably priced with good reviews I could find
*by I***E on April 14, 2018*

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.
