Great for an Apartment Renter!
Excellent products for an apartment! Works great, easy install with the double sided tape. For the price, the system is great and it will be easy to remove when moving out. It's also nice to see that Eufy has brought out more accessories for this system. I am very happy with this purchase and I would definitely recommend it for those renting an apartment. Just easy to install, easy to remove with the tape that has never, ever come loose, I think this is a great not overly expensive alarm system for apartment renters. Very happy with product and price!

Satisfied with this Eufy ecosystem, I am now adding more of their products to it.
This system is very good, it’s easy to setup, the connectivity to the internet and alarm functionality very good. Video quality and its durability very good. I’ve had it for five years now and I am still satisfied.

Batteries were DOA - And A Few Suggestions
Nice little system for the money. For design, I'd give this 4.5 stars, taking off half a star for the low alarm volume, as the other reviewers said. It is weird they don't have an add-on siren. I have not tested the motion detector as extensively as I would like to, but it seems to work fine, and I like the fact that the sensitivity is adjustable. The door sensors were easy to use. I found the manual a bit irritating-- both the online version and the paper version. I would have liked more detail: Does the system send a signal to the base station through wi-fi, some other RF frequency, or is the wi-fi just used to send the alerts? But I was able to get it set up, once I figured out that the batteries were dead and I had to order new ones. Minor quibble. The biggest issue is that the batteries were DOA, so you're not really getting a $150 system on sale for $110. To get decent batteries, you'll have to pay at least $10 to $15. So let's say it was $125, and still a good deal for that price. -- You will want an UPC (uninterruptible power supply) for the home base unit and for your wi-fi if you have a breaker box outside. And if you're going to be away for a while, I'd disable the alarm on that UPC. So if the thief shuts off power to your unit, they won't hear the alarm of the UPC, and will probably figure there's no power to the alarm system. And be wrong-- if they break in, the system should still work, still sound the alarm, still send you a notification. -- I think the alarm volume could be solved, though it would cost some money: Get a little guitar amp, either with a rechargeable battery or on another UPC, get a little lavalier microphone (that is the correct impedance for the input, which will be a PITA), put the mic under the Home Base, and just leave the amp on, cranked up, all the time.

Great security system for apartments and small spaces.
After almost a year of use of Eufy alarm system I would say its a great system for limited purpose. It will NOT replace an exterior alarm system. The sound of the alarm is low, which is great for apartments or if the use will be more for monitoring than deterrence. Here I share some pros and cons. Pros: • Door sensor can be used as door chime. • Easy and quick setup. • Small and lightweight. • Quickly notify any setup event to the phone. Even when the Homebase is not working properly (see cons). i.e. if a door is opened a notification is received within a second. • Schedule modes, setup multiple users/ passwords. Cons: • Homebase reliability: Once in a while I have had to restart the Homebase because the chimes are not working. I have been unable to restart the homebase thru the App even though it has an option. • Automation limitations: Some devices can be linked to the Homebase, others can not. Read carefully before purchasing. But it is easy to control each device within the App.

Great setup
Worth the modest price. Everything runs seamlessly and is easy to deal with.

Good home alarm set
I purchased this alarm set to replace the old ADT alarm set in an older home. Installation of the sensors was simple and quick. I mounted each set of sensors with the sticky glue pad and also secured them with the provided screws due to the strong magnetic force pulling a magnet to the nearby sensor in proximity. For reliable connection, I chose to connect the home base to the internet using the provided Ethernet cable. I installed the keypad on the wall along a hallway next to a protected receptacle with USB (see attached pic). I read the instructions for each of the devices a couple of times which were clearly written with illustrations, then I followed the instructions to the letter for step-by-step installation starting with the home base, the keypad, and lastly the sensors to get them all working together before actually mounting the sensors. The whole process of installation was simple, I didn't encounter any issue (such as firmware update, and dead batteries) described by some reviewers. The alarm set has been working as expected since it was installed. By default, the home base will notify you of all open and close events detected by the sensors, which may be too much for some folks. However, the controller app, which is easy to navigate, would allow you to customize the settings for each of the sensors to minimize or turn-off notification completely. You can choose "Home" or "Away" mode either by using the app or by using the keypad, which will require validation with the PIN first. 12/12/23 Update: An update of the Eufy Security app on my mobile device sometimes last week causing the following issues: 1) I couldn't open it, it kept crashing, 2) The annoying warning "This accessory is not supported" kept popping-up, 3) whatever the app was doing, it caused the battery to drain fairly quickly, I had to recharge it multiple times each day, I never had to do that in the past. To fix the crashing issues, I had to delete the app then reinstall it from the Apple Store. Reduced 1 star for poor quality app.

Easy to install and setup, a great DIY solution for the price
I purchased this alarm kit since I own a set of eufycam 2C at home. The good thing is I can use my existing home base to add this alarm system under the same eco-system. This alarm kit is easy to install and setup. The quality is solid. So far, everything works well, tried the alarm, and it sounds loud. Besides, it seems the battery life of the motion sensor and the entry sensor is quite long, which is good considering the price point. No monthly fee is good. The eufy security app is easy to use as well. The only complaint so far is that the eufy home alarm kit has not added any options of 24/7 professional monitoring services. I really hope eufy can add this feature in the future because I do wish there is a professional team that can back me up in case something bad happens. Overall, this product is good and very easy to install and setup. This is a good option for DIY home alarm systems for the price.

Great for small apartments
This system is a great option for small apartments. The app interface is easy to navigate and has customizable security settings for all devices. The alarm is loud, especially in a small space. I’d imagine the complaints of inadequate volume apply more in a larger space. It is a self-monitoring system and does require WiFi, but it will still notify you when you’re away from home. All and all, it’s an easy and affordable way to have peace of mind.

Super easy set up
Easy to set up. And loud enough to scare off intruder..i think. Also, very versatile in usage and sensors are readily available anywhere when decided to add more.

Really good choice for me
Research many many alarm systems, watch many YouTube videos and settle on this system. Wasn’t disappointed one bit. We moved into a new house and wanted some home security with no added cost. This surly is the one for home owners. First off there’s no fees. Easy to hook up and monitor all from your phone and pretty much that’s all you need. The siren is pretty loud if triggered. The system comes with 2 door contacts but I got another one so for me it’s my front door, patio door and the man door in my garage. When armed if doors is opened the siren is on and your phone sends a notification. One tip for people is your doors doesn’t have to be flush with the crown moulding, the contacts will work. Many YouTube videos says otherwise. My new house, the door and the moulding is far from level and to my surprise it looks.

Is a US product.
The price was right, but factor in buying a 12V 2A adaptor with an Australian plug. Warranty may or may not be easy to get too. Easy to use and install but left disappointed getting a US product.

No cumple con la norma mexicana
El adaptador de corriente es europeo y no sirve para México.
