Question: what does the alert sound like?
Document: This is a great product foe home or business .I love the chime sound to alert me about who is entering my path.
We finally wised up and bought an outside mirror for the porch so that we can look out the front window and see if the alarm is for the cat, the deer, or if someone has arrived for a visit/delivery. We are very happy with this Safety Alert and would highly recommend it. It's like caller id - you know someone is here before the knock on the door.
i didn't like this product so much after receiving it didn't have the range i was looking for i exchanged it for another brand.
Works like I expected, low maintenance, no problems, would buy another one just like it. I think the quality for the price was good value.
I mounted the sensor very low on my back door to monitor my dog,  when he's done, and ready to come in, the two sound levels are great,, I bought a power adapter to avoid replacing batteries.
This has an annoying sound that scares the h ll out of our dog. Our last one was musical and was much more desirable, until it broke. I do wish I was able to hear this one before ordered as I would not have done so, but it is now connected and I have to deal with it, hoping it will break daily!!! P Pratt
It is exactly what I wanted to replace an old alert system we had in the past. It lets us know whenwe have new customersif we are in the kitchen.
I purchased this item to alert me when someone is coming down my driveway. Works just the way I had hoped it would. The only negative is that a really windy day will set off. I can live with that.
I bought this product to protect my backyard from potential thieves. Either the advertising was a bit confusing or purposely meant to be deceiving. The distance for the alarm and detector to work together is up to 400 feet but the actual distance of motion detected is listed as 8 meters or 24 feet but it's actually more like 15-18 feet but that is more than enough for what I need. The angle of detection from left to right is about 30 degrees or so. at least that what the box says.
The Ideal Security, Inc. wireless safety alert device works great. I'm able to hear the alarm at a good distance , and I can rely on it to let me know when I have a customer.
Answer: Two choices -- a blaring, constant alarm or a loud chime that sounds like a doorbell on steroids.
