Decibel Meter 13 Inches Wall Hanging Sound Level Meter Data Logger, Noise Meter with 16.4ft Sound Sensor, Audible and Visual Alarm Sound Meter for Decibel Level Monitoring in Classroom, Studio, Home

What's Good:- The display is very large and bright. We use this at a venue to keep the DJs from playing too loud, so it's mounted high on a wall in their line of view.- Setting a dB limit works, and the display flashes if the limit is reached.What's Bad:- The instructions aren't clear and are confusing. For example, it states it has an "Eternal Alarm Output Interface: Can be connected to an external 12V alarm" - the problem is that the label on the meter says 5v output. Thankfully, connecting a 12v strobe to the output did work, so it seems the meter isn't properly labeled.- The biggest issue I have is trying to get data from the unit, which for me is basically impossible. To power the meter, it uses a 5v USB connection. But, to track and read data from the meter, you have to use the same USB port connected to a computer. As there appears to be no on-board memory storage, from what I gather, you have to have a computer connected to the meter ALL THE TIME to be able to look back at any data! I would assume most people would want to mount this, as I did, high up on a wall where it can't be tampered with. Mine is located in a dance hall, with no computer anywhere nearby. So, for me, while you can technically get data from the meter, having a computer constantly connected makes no sense.I wish that there was some on-board memory that I could download the data from the unit (which is implied in the product description, "records the data of decibel level every 2 seconds, and be able to store ONE YEAR data"), but according to the instructions, that's not how this works. I tried reaching out to the company but didn't receive a response. Will update the review if I find something else out.Update: I've now had a chance to connect a computer to the meter, and discovered two things:1) As I suspected, the meter doesn't have any internal memory or clock that will continue to work when the unit is unplugged. Recording of dB limits is ONLY possible while a computer is connected.2) The Windows software that I was directed to download is useless: most of the menus aren't drawn correctly on the interface, and many areas of the software simply don't work. The software was obviously created in Chinese.Summary: The meter itself works as advertised, however if you're wanting to be able to have log files and can't have a computer constantly connected to the meter, this product isn't for you.

No issues, alarms sounds we haven’t set up the computer portion yet, but will soon! EASY SET UP, worth the price!
