  • Easy to install with straightforward operation
Style: 9 Piece Kit
Guessing that a lot of these purchases are event driven and mine certainly is. We have a cabin and a barn on a 6 acre piece of property. The barn is where we park the tractor and store the supporting tools and supplies. The barn was recently broken into and everything of value was taken. While that is deeply disheartening, it really only affects me. If the cabin were to be robbed and ransacked like the barn was, I have several young children that would likely never want to go/stay there again. I do consider myself handy when it comes to mechanical and electronic projects. I also believe that I am a good researcher and analyst. I found that there are a lot of great alarm systems available at very affordable prices today including DIY professional systems. Several of the professional systems now have videos on installation and configuration—configuration used to be the tough part of installing one of those. In my case, I was looking for a balance of price, ease installation and options for monitoring. Given the recent break-in, I also wanted to get this project started and completed quickly as the cabin is just as vulnerable as the barn. This next statement may make you question my research, or at least, reading abilities. While I did plan to have the system monitored, I didn’t realize until after I purchased my SimpliSafe system that you can’t monitor the system remotely at all with the app without one of the SimpliSafe plans, and, at the time of this writing, March, 2021, you have to have the $25/mo. plan to do any serious monitoring. I would have putt off having the system monitored for a while if that were not the case. Perhaps it is better that I was forced into a plan earlier than I wanted. As an aside, SimpliSafe gives you 3 days of ‘practice’ use after you activate your system. This means they won’t contact local law enforcement if the system detects and alarm. On the one hand I wanted my system monitoring to start immediately but, do understand the logic of giving me time to learn to use the system without causing false alarms. The installation was truly easy. Once you plug in the basestation and pull the battery tab on the keypad, you are off to a great start. Installing any of the sensors is as easy as removing a paper battery tab, using the keypad to tell the basestation that you are installing a new device and naming it from a list once the basestation announces that a new device has been detected. The preinstalled double sided tape makes mounting the sensors easy. Our cabin has numerous unfinished roughhewn wood surfaces and I decided to mount sensors that had to be on those surfaces with the included screws. I didn’t try the included self-adhesive on the roughhewn wood which, may have worked perfectly. SimpliSafe tells you how far away you can mount sensors like the glass break and motion sensors but it was less clear about how high to mount them given the space I was working in or, for the glass break in particular, the angular range that it could work with. For example, if you have windows on opposite sides of a room with no option to mount the sensor in the middle, can it detect glass breaking behind it or beside it? SimpliSafe sensors are relatively inexpensive, and, as such, perhaps an extra sensor or two isn’t a bad thing. The App is easy to set up and use and definitely slanted to the easy side rather than the comprehensive side. That said, if a sensor were to drop off the app will alert you to that. I am not looking forward to changing batteries but would rather that to running wires through an older structure. SimpliSafe has done a great job making system purchase, installation and operation easy and straightforward. They even sent me an e-mail letting me know that the county where my cabin is located requires a form and payment to be completed and sent to authorize monitoring and, more specifically, response. Not only did they tell me about it, they sent me the exact link to the form. They also let me know that no paperwork or fee was required for the fire monitor. The cabin can be a relatively harsh environment with high humidity in the summer and relatively cold nights. I am hoping the sensors, base station and keypad are rugged enough to function for years to come. If you are looking at one of these systems, read all you can to understand what you can and can’t do with and without SimpliSafe’s monitoring options. Watch or read about sensor placement and plan your own install. I don’t think you have to become an alarm expert but each install has its own challenges. I found plenty of good information available from a lot of sources on the Internet to address those challenges. I have not interacted with SimpliSafe’s customer service at this point and can’t comment on that aspect of the product. Overall, I believe I made a good decision for my family and have only positive things to say about the installation and operation of my SimpliSafe system. ... show more

  • Easily installed, and realible wireless home alarm system
Style: 9 Piece Kit
After much consideration and reading up on security issues with current wireless alarms that rely on internet (IP) connectivity for their controller app., I found that the Simiplisafe alarm was the best choice for use in a rental home. Just ensure your wireless network runs WPA2 encryption. All of the the wall sensors are very light, and can actually mount with quick-remove 3M adhesive strips, even the larger motion sensors. Setup was really quick, and easy. There were no issues loading the app, connecting the base to my home WiFi, pairing to the alarm, or adding sensors. There are no dongles to arm/disarm, but loading the app to phones for each member of the household was easy. One sensor mounting issue I ran into is that there is no adjustment to the motion sensors. Other brands have a base that pivots, but these mount flat to a wall, or at 45 degrees. You have to get creative with position or they wont protect the areas of coverage well. The indoor IP camera in the kit actually works too well. There is so much sound, you are constantly hearing humming of motors or fans in the house. However, when someone actually walks in, it picks up that sound crystal clear. The night vision is quite good as well. The app. is super simple to setup, and has worked reliable everywhere I am, even across the State. The ability to add outdoor IP cameras is great, and the control panel has a quality feel, with easy to read screen, and great night lighting. The base unit has a built-in battery backup, and is easy to place anywhere you need it. The furthest sensor from the base so far is about 75 feet away, and on a lower floor, but function has been reliable. I have installed multiple alarms in rentals, and really feel like this is the best one so far. It's a great product for anyone needing a wireless alarm option that is reliable, and secure. ... show more

  • Easy DIY Security System
Style: 9 Piece Kit
This is a great security system which is easy to install. I installed the four entry sensors, two motion detectors, the camera, the base unit, and the keypad in about an hour. The Simply Safe App walked us through the installation process. The sensors and keypad come with sticky tape already on the devices so no holes need to be drilled. We purchased a second keypad which was easy to add to our system. So far everything is working great. My only complaint is about the camera. It does not have a slot for a memory card, so it will not record video unless you subscribe to the monitoring services offered by Simply Safe. Overall, it’s a great system. ... show more

  • Worked for Australian User in June'24 - Guide how to set up
Style: 9 Piece Kit
In Australia, *US to AU plug adapter required for home base* power it up! At the time of writing this review I was able to download the Simplisafe app on Google play (android) only upon checking the apple store I couldn't see this app in Australia. So on my android device I signed up as a user entered my Australian mobile and had the ability to verify to my Australian Mobile and gain access to my account. When you access the app and signed in you'll be asked about the monitored plan, in my case first time I got a blank screen tried again and nothing, so then I connected to my VPN under USA and was able to decline the monitoring plan and was able to get to the main page to set up all the devices as part of the package. Once the app was installed I followed the simple instructions to add the homebase, connect to WiFi and update the base stations, this took a couple of attempts but second time the base station had LED colour coming from the base station and updated the base station. Then I followed the extremely easy steps given on the app to add each device, motion sensors and door sensors, simplicam & keypad in my case, note the tape on the sensors wasn't very sticky, may I suggest that you buy 10mm double sided tape to stick to surfaces. Simplicam took a minute or two to update but not too long. The app works on 5G Telstra Home internet, so I can only assume this would work on the likes of NBN. Once all devices were set up I was able to mess around with the setting to suit my needs. I had the ability disarm and arm my purchased alarm and pleasantly happy with the small size of the sensors and the quickness to set these up and add multiple PIN numbers. ***Important Note*** In Australia at the time of this review you CAN'T link this system to your Google home as it's a paid monitored subscription in the USA & UK only, so access to keypad or app required for use. If you want more than one user you'll both need to both sign in to the same username and password "not biometrics" use the password and on other devices and add other devices, you can do it by the mobile number is is gives you USA, Canada & UK, but signing in on one device only at a time, when away from home will allow you to arm, disarm, view camera but not to record only view in LIVE time. This system is focused around the monitoring packages for being able to record, link to google home etc, but those looking for a smart home alarm in Australia for basic additional security the may deter an intruder then this system would be perfect for you, basic alarm needs, I'm not expecting miracles but the system is fantastic value for the money asked and looks and performs great, could be a little louder on the chime but you can buy accessories for this purpose and like the battery back up on the home base as all the sensors as battery so in the event of a power cut you have security noise, not camera's, and it's quite easy for someone to turn your power off from the power meter outside your house. I hope this detailed synopsis helps you make your decision and it's been a great purchase for me. ... show more

  • Great system
Style: 9 Piece Kit
I got this system recently on Amazon and it has been working quite well. I love the fact that I can use my phone to arm, disarm and other functions. I did not subscribe to the monthly monitoring by the company as others recommend. It is a good idea depending on your budget but I feel what it is doing at the moment is exactly what I need it for. Setting it up was pretty simple. I have the two inside sensors which I am pretty much utilizing even when at home because we sleep upstairs so we need the downstairs activated at night. I put the indoor camera in my garage and it is working just fine. The only downside is that I have to subscribe to be able to view recordings. Although I am not subscribed, I still managed to get hold of support where I just wanted to ask about the warranty. They are responsive and I give them a 5 for that also. Overall, it's working, I love it and will not hesitate to update my review if I face any challenges. ... show more

  • Excellent Home Security System
Style: 9 Piece Kit
Excellent home alarm system that is very easy to install. The video instructions are super to follow. I used the sensors on the doors (front, side, sliding glass and garage). I purchased a break away holder for the garage door which works great. The motion detectors are mounted in the family and living rooms. They are activated in the Away mode along with the indoor camera. Great value for the money. ... show more

  • Simply Sucks
Style: 9 Piece Kit
By far the worst product experience I have ever had. Sure, setup is pretty easy but soon found out system works less time than it actually works and have to spend every day maintaining a series of different errors, such as devices that randomly stop working, 'keypad out of range' when it is literally less than a foot away from the base station, keypad offline. Once the app indicated the keypad was offline, but then it correctly triggered when I entered yet alarm sounded off for no reason then the very next day, the app indicated the keypad was on, but then did NOT trigger once I entered. Customer service is hard to get a hold of, inconsistent and love giving you the run-around asking you for things like the product and serial numbers that I am sure they already know, not very helpful. Said they would offer a free month of monitoring, but failed to follow through. Simply Sucks!!! Don't buy this product! ... show more
