S SELDORAUKMotion Sensor Door Chime, Dog Barking Alarm Doorbell Guard Wireless Infrared Detect Alert for Home Security Reminder Entry Rang 1000ft 110dB 4 Volume Level (1Receiver+1Detector+1Remote)

Had all 8 of my koi taken by blue heron in one week and wasnt happy. I put this by my pond (1,500 gallon ) and it chased off 2 blue heron on the first morning put out !!! Has nice volume,just be sure to remove the clear tape over the speaker grill or it wont be very loud!!.It will recognize me starting at about 25 feet away and be pretty consistent on detecting me under 20 feet. The dog barking sound is what i use because it seems to be not quite as loud as the car alarm sound but it still has good enough volume to chase them off.. I have people living beside me and I dont want to bother them with the car alarm sound..The car alarm sound is WAY WAY louder than the dog barking sound.Its so loud its almost annoying ..lol...If I had no neighbors I would use the alarm sound.. I hope this thing lasts awhile because it seems to be working good...Also do yourself a favor and get the alarm that has 2 receivers so you can put one in the house so you know when your unwanted guests come to your pond !!! Its only about 10 bucks more !!!

Love it. Sounds realistic.

Read to end for the grand finally as to why 1 star. For what it is. It works. But could be louder. There definitely isn’t “4 speakers” in this thing. The light on the motion sensor illuminates brightly exposing its location. Anyone can easily put two and two together to figure out that when it lights up and hears sound that it’s not real.It does work though so far. However when emailing customer service with the included card the company got rid of the email. Got an “undelivered mail” response so they don’t even have customer service. The device was made exactly one year ago the manufacture date sticker has a date of 4/23. So that means the card included with the customer service email is only a year old and completely illegitimate.Personally I would advise you not to buy as a lack of customer service is a big no-no.So it’s 1 star for bright red light on motion sensor and 1 star for complete lack of customer service. Hopefully they fix the customer service issue then I would redo my review on that part.

I bought this because our very verbal dog died and I needed all strangers to believe we still owned a guard dog. This product does the job. My only complaint is the growling that comes with the bark cycle. It is not necessary and does not match the size of dog that you hear barking

Love that the dog barks are so real sounding. It was very to install and work. I would recommend this product to anyone living alone.

The design is my opinion is poor. The remote sensor lights up all in red upon motion. I tried to black tape to cover the red light but too wide spread. This would TOTALLY ALERT an intruder that it is fake, motion sensored and NOT a real dog. Could be louder as well. POOR DESIGN

This product works well. Motion detector sets off the chosen sound of your choice. Volume control goes from quiet to very loud. Numerous dog sounds, doorbell sound or others. I love it!

I love the remote control aspect of this product! If you think you hear someone at your door at the wrong hour of the day or night, just press the button and scare them off! It really works!
