HENDUN Door Alarms When Opened with Remote, Door Bells Chimes, Door Security Sensor Pool Alarm for Kids Safety (2 Pack)

This product is great. I had these before to alarm my doors because my husband had dementia and he would wander. These alarms are easy to install

So far everything is working as stated. I received 3 sets and I paired them so all 3 will work at the same time with 1 remote.

Me gusta, pero mi puerta al no ser lisa no se adapta bien, tener en cuenta esto, pero funciona y suena bien y es muy sencillo de instalar, va con pilas .

Easy to set up. Loud.

Definitely gets their attention it's nice and loud Works great easy on batteries

Small magnetic senor has 2 small screw holes for mounting or use double-sided tape, the larger Alarm sensor has no screw holes for mounting and need to use Double Sided Tape (included). Does not include AAA batteries as each requires 2 or total of 4 batteries. The Remote must have a watch/calculator battery inside as I did not need to insert/install any battery. The Siren alarm is very loud and continuous as the Door Chime is half as loud and sounds like the small ringing/chime you get when entering a Small store.Read that these Door Alarms will drain the AAA batteries in less than 2 weeks. The Remote control has 4 functions as in Lock, Unlock, Siren, and Bell. On "Lock"/Off "Unlock".Need to place the Remote Control unit in a safe and inconspicuous place. The Remotes are not Labeled so you may want to.Currently using the Door Chime setting because the Siren can wake up everyone in the household or if you reside in an Apartment complex will annoy your neighbors. If alarm is triggered in an apartment and no one home able to turned it off, nice way make your neighbor angry and want to bust your door down. Only have used it for 1 day, and No False Alarms - going off by itself. Will need to keep tabs because said it may drain the AAA batteries rather quickly.A set for $26 is cheap. Hopefully they will work for a couple years or more. Otherwise, may need to spend a few Hundred Dollars and pay out for a Security System with alert notification like ADT. All depends on your needs and valuables trying to prevent theft.

Perfect!! These are exactly what I needed when moving into a new area I am not familiar with. They are priced right and definitely work! I accidentally bumped the door not too hard and one went off which made me feel safe knowing it worked. They are definitely loud enough to hear going off in the basement while I am on the second floor back bedroom (just a test)The chime option would be great for people that have children who you don’t want to “escape” into the yard without you noticing.

Perfect item for your house.the alarm is so loud that can wake your neighbor.
