Wsdcam Door Alarm Wireless Anti-Theft Remote Control Door And Window Security Alarms

This alarm is fantastic! Easy to install, thanks to the double sided adhesive pads that were included. The remote is great, and small enough to put on a keychain (and it's designed with a small slot for that purpose). I love that you can arm or disarm it with a button press on the remote, and the chime button is neat, too (alarm chimes each time the door is opened). I feel a lot safer with this alarm installed, since it gives me some warning if someone is breaking in, and may help to scare off an intruder. I armed it last night before I went to sleep, and put it back on chime thus morning. Gotta love it for $8.99 delivered from Amazon. BTW, it's surprising loud, too. Also, I've hsd no ptoblems with the remote working from my den or bedroom. I don't know what kind of battery it uses, since it's internal to the remote. But it works great. The door alarm that you stick to the door requires 2 AAA Batteries that are not included. So, make sure you have a couple on hand. I very rarely write a review this positive. But, in this case it's warranted. Thumbs up, 5 stars, wonderful product!

Nice compact alarm with loud notifications

I purchased this for my newly built shed. It will house some expensive gear. Even though it has a Ring Camera and a back-to-base alarm, this gadget, added to the entry door, will certainly give an intruder a heart attack. I hope so, because if it does, I won’t need to call the police. A must have for added security.

Great

It's not as loud as I expected. Now, don't get me wrong, it's loud, but after seeing all the reviews that said "omg it's so loud" I expected ear-piercing ear-hurting loud. When it goes off when you expect it, you'll automatically squint-your-eyes/cringe while you look for the noise source to try to turn it off. Now that I think about it, maybe it's not louder because of health reasons. Now... If you DON'T expect it, your heart will definitely skip a few beats from the scare. Happened to me when I accidentally pressed the panic button while having the control in my pocket while moving some furniture out the door. I went to bed and hid under the sheets for a few minutes to get over the scare. My gf opened the door once without deactivating the alarm, and she also got quite a scare (she'll now never forget to deactivate it before going in the apartment lol). We activate and deactivate the alarm when going out, as in, when there's nobody home. And since the alarm is located on the inside, the closed door muffles the "activated - deactivated" ring. Unlike others have commented, this activated/deactivated ring isn't as loud as the alarm... but it isn't quiet neither. The door is weatherstripped for noise and temperature differential insulation, so the activated/deactivated ring doesn't bother any of the neighbors. So, Pros: 1.- Extremely easy to install. 2.- Inexpensive. 3.- Will give you a heart attack if you are prone to one if it goes off without you expecting it (like a burglar). Cons: 1.- The open-close door chime function is so loud it's almost useless. 2.- If you're a dedicated/expert burglar, the FBI or whatever, you could locate the alarm and take the battery out to shut it off (which is why we have another alarm that informs the building's security guard). But these security things are never meant to keep the "pros" out. 3.- You MUST have the control to activate or deactivate it, no password or anything. So you should definitely invest in buying a few more controllers in case you have family/friends coming over to let them in while you're not home. The pros heavily outweigh the cons. Five stars.
