Amazing gadget for security alert

My analysis of this device showed that it's a great reliever for our office security. It's easy to install with a loud siren and strobe light graphics to generate warning signals in case of security breach. We also appreciate the automatic shut-off feature and the adjustable sound levels. The only downside is the price, which may discourage people from investing in such electronics.

Pros
  • Easy to install and efficient in generating signals
Cons
  • The price may be prohibitive for some users.

Poor quality and sent the wrong ones.

Loud enough for my purposes, but the sound quality is very poor. I would give 2 stars but the description clearly says an intermittent tone and this is a continuous signal.

Pros
  • Electronics
Cons
  • boring packaging

They sent the WRONG buzzers - got solid even though they are marked as intermittent

I finally needed the buzzers I ordered a few months ago. Unfortunately, the devices are mislabeled and deliver solid sound; not the intermittent noise I expected and ordered. Of course I missed the return window by 2 weeks so I'm stuck on these things. Don't buy them if you don't care how they sound.

Pros
  • Security and Surveillance
Cons
  • I vaguely remember
