Great addition to your alarm system

This is the greatest thing to add to your Honeywell Vista 20P panel!  I have installed several of the EVL-3's and this EVL-4 seems about the same but it is much easier to bring up and program to the panel.  It gives you free remote Arm/disarm from your smartphone or computer and it gives text messages as to status, alarm, etc.  For only about nine dollars a month they will provide monitoring services (way cheaper than most places), but I just use the texts to my iPhone.  Had a break in last Summer and was alerted immediately.  The texts let me know they were only in the home for 51 seconds and I called my neighbor within a minute.  He was already on it.  Nothing taken.  Again, great product!

As a police officer, I see firsthand the downfalls of having a security company monitoring home or business alarm systems. Once the alarm is tripped, it is dependent on the company receiving the alarm, then them alerting the local 911 system, then law enforcement being dispatched. It is frustrating arriving quickly after being dispatched to a legitimate alarm and only learning later the actual alarm had been tripped 15-20 minutes or more before.  Long after the suspects were gone. I bought Piper for my home to alert me personally, in real time, to allow me to see what the alarm was (sound, motion, etc.) and watch/hear video to make a determination on how to respond. I have not been burglarized as of yet, but have been alerted via text to legitimate sound trips and was able to assert immediately of what had occurred.  This along with a very loud audible alarm makes me confident that if I am the victim of a burglary, I can respond to it quickly and the suspects will be less likely to spend any amount of time inside, if they enter at all.  I also like the capability of an alarm trip turning on lights and recording the event. Plus all the other available features of the system make me sold. I highly recommend a Piper system for home and business alike.

We love it, will probably not renew our alarm system monitoring contract after it expires. This combined with a smartphone is an ideal security system if you live in a fairly safe community. Easy to install, no wiring, load apps to phone/tablet/pc in minutes.

Really like the features of this alarm clock. It is a bit smaller than I thought it would be from the picture, but the brightness of it makes up for it. I find it simple to use and does what is supposed to do, wake me up.

This device is a great security addition to your home. It allows you to see who is at your front door,  whether you are home or not..

Love the big easy to read digits. I also like the ability to adjust the brightness of the display. May be too many features or a little complicated for some users. But if you want multiple sounds and alarm settings, this alarm clock will definitely fit the bill.

Great alternative to the high priced alarm systems.  I love them.  I have them on all the windows and doors.

The Z Wave made it easy to install with my alarm programming system . I have only had for a month. However, I love the dBA volume, and the tamper feature. It was priced a little higher than what I wanted to pay, but I guess a small price to pay for the intended use. I was glad I found out about and purchased three of them.  I would recommend it to everyone.

Very easy to set up and alarm is loud enough but not too loud. Does what it's supposed to do.

Great alarm for your sump pump pit.  Works great and easy to setup.  Plugs in the wall and uses your home wifi to send an email and/or and App alert to let you know water has been detected.  I set it up to monitor the water level just above the sump pump float level so I know when the pump is not keeping up.  Will send email alerts and/or App notifications.  You can see in the app if the sensor is offline which could indicate a power outage or internet outage.

This alarm provides me a peace of mind when I leave my apartment unattended. It is loud and would likely cause panic to anyone who tries to break in. It works well and can be installed and set in a matter of minutes.

Great alarm, works well and actually saved my bike from being stolen once already.

These units work great. They will interconnect with each other to warn the hold house of a problem. Very loud and easy to understand. I have just purchased four more to give to a relative. You hope that you never have to have them go off in a real emergency but it is comforting to know they will wake you so you can take action to evacuate. It has announcement to tell you where in the house the incident is.

Works as advertised, and definitely very useful when you need an alarm that does not make noise. No major problems, though life expectancy can be lowish (like 6 to 9 months) for the price.

The alarm works well -- sounds more like a UK police siren than a US firetruck siren like I was expecting.  It's loud enough that it can be heard throughout the majority of the house.

When setting up, if you make a mistake and need to correct it, you need to start over -- no correction could be made that I could find.

All that being said, the radio works very well for what it's intended.  The alerts that I have set up are the only ones that I receive (thank goodness).  The lights on the panel tell what type of alert it is, and there's a scrolling LCD that tells what the alert is.  Of course, you can just press the bar and get more details.

One thing that I really like is that when an alert sounds, the radio comes on for a short while so you can hear the alert, then it goes off.  You can easily come back after being out and see if an alert is effective by looking at the panel.

Overall, very happy with the purchase.

Delivery couldn't have been better!

Nice and loud, accurate, and easy to figure out in moments.  It also gives reminder beeps after the initial span of alarm, just in case you didn't hear it.  And the display will let you know how far you've gone over the intended time by flashing the ascending time onscreen.  Looks good and good quality.  I'd recommend it in a heartbeat.
