Perfect for security minded homes

Perfect for a front door with glass panes.  Cant see in at all from the street and nearly at the door itself, even with lights on inside

It's  easy to install and ready to run. Super loud which is good for any alarm and annoying. Overall I felt peace of mind after setting up the device along with using a u-lock is great combination security. Highly recommend still using a U-lock with it.

These worked as described and I love them.  I feel more secure and the motion detector works perfectly once you tweak it just right.  I like how you can adjust the angle of the sensor, too.  Easily installed, the light sensor also works perfectly.

This is by far an awesome home security device. The video is crystal clear both day and night. I place mine aiming at the front door and if anyone opens door it instantly notifies me that I detected movement and saves video for viewing later. So even if the robber unplugs camera too late

I just installed this in my home. I love the warning features. It will let you know if someone goes in or out. The alarm is loud enough to hear outside. I think this would make most intruders leave. It is well built, very solid.

So happy about my new security device! This is by far the best security system I have ever used. It is super easy to set up with the app and it is small and discrete enough that it is hard to see (looks like a small speaker). It is so nice to have peace of mind that it is keeping me and my roommates safe. Also, it has so many features that many other security devices lack, such as monitoring air quality, connection to your phone and computer, and ability to talk via a two way "canary talk" that allows for real time conversations. It is so easy to log in and check in at home.

Awesome security system for the price! Easy installation and set up for even the inexperienced. Great peace of mind when I am home or away.

This system works beautifully. The angle of coverage is sufficient as is the night vision capability. The internet interphase allows me to see what's going on at home no matter where I am in the world. No home should be without this level of security.

I work from home, so I cant always get up and go check on whats going on inside or outside my house. After installing multiple exterior cameras, I bought one of these for some interior coverage in the living room at the far end of the house. Setup was quick and easy, and gave me the peace of mind of being able to check in on that suspicious silence in the house (parents will know what I mean). I like the included wall bracket and the option to mount it upside down - I just wish the screw attachment options allowed for a tighter/closer fit to the ceiling when mounted inverted. Bought a second one for my home office to keep an eye on my equipment when Im not at work.

FABULOUS idea.  Easy installation for the average homeowner.  If you aren't looking for Ft. Knox type security this is for you!  Affordable, easy to install, up and running in minutes.  I think this is a HUGE amount of security.  For a woman living or staying alone, this is for you.  Peace of mind and you can do it yourself without anyone needing to be informed of your new security system.

Great value for the security minded. Just two of these bulbs are enough to bathe my entire backyard in light, leaving potential intruders with nowhere to hide.

Personally, I think they might be too bright for indoor use if you don't have a dimmer switch.

I was in the market for a SAFE key-less entry door lock for quite some while. After watching YouTube videos showing that practically no key lock is safe or can't hold more than 5 seconds, I was sold on a key-less one. It only offers that much safety because, honestly, who wants to penetrate someones castle, will do so regardless of the lock, even if cutting a hole next to the door with a chain saw :)... I decided to get this particular lock with Z-Wave radio because it's sturdy and it comes from a fantastic brand with over 150 years in business. As soon as I removed it from the box, I knew it was a great decision. Now to the fun part: Implementing it into a smart home scenario... The idea is not to go and touch like crazy that touch-pad, but let the smart part of it do the job for you. It senses in various ways the returning home and it will open the door while you walk towards the entry so that it will be open by the time you need it to be. Once inside you can turn it by hand to lock it or you could tell Alexa to lock it for you if you don't have a free hand... You will be able to check online the status (locked/unlocked) and lock it if necessary; you will get a log with time stamp and identified person for each operation. The "bad guy" will have to find a different "week spot" because this one is not something he would want to mess with since it is also capable to trigger an alarm system. All in all it's exactly what I was hoping to get and it works beautifully. In order for features to work automatically you will need some more equipment since this is only a bit of a system.

For a change I wanted to install a security system in my house 'before' we have a break-in.  Usually people (including my neighbor) wait till after!
I looked at a few systems.  Some only work on regular phone line (no VOIP), some work on a VOIP line (including this system), and some work on dedicated GSM which needs a monthly service plan for the SIM card.  The latter is probably the most secure if the intruders cut the land line before breaking in.
I decided to go with this system since I didn't want to pay a monthly fee for the GSM service.
Also, this system supports wireless sensors which are much easier to install, though you need to replace the batteries in the sensors maybe once a year.
The installation was a breeze.  The manual is well written and gives step by step direction to program the different types of sensors.  Installing the sensors on the windows and doors took me some time since I have Aluminum frame windows, which needed drilling etc..  The key fob work great for remotely arming and disarming.  The extra remote keypad is also wireless and is a convenient since it allows you to arm/disarm from close to your door if you have the main panel installed elsewhere (closer to a phone line).

Overall a great system and the quality seems to be really good.

The company also provides a monthly professional monitoring with this system for a nominal fee.  Though I didn't opt to use them.

My husband has installed these on 2 houses and a total of 3 doors.  The current one for 2 doors for 2 years now.  We love them.  No batteries to worry about and no keys.  You are not going to change the combo every day, but it is not that hard to do if you want to change it periodically.  All 3 were installed in existing doors. Would not use them to secure a bank vault, but given how easy it is to break most homes, these are good enough.  They will probably come thru the window first and most locks keep out the honest people and petty thieves not the true professionals.  You can always give someone the combo if they need to check something for you if you are out of town.  If you have a standard key deadbolt, this is worth the replacement.

Affordable piece of mind knowing if someone is coming or going on your property. Works great! Every household should have one. This set is so nice because it has 2 sensors with it, so it is perfect if you have more than one entry to your home or business.

This is the perfect device for people that want added security but are not able to modify the property! The bar is a quick and easy setup and does a very good job of bracing the door. I thankfully have never had this device fully tested in a real emergency but if the time did come then I feel confident that this device would buy precious minutes for police to arrive if worst came to worse.
Pro:
Very fast setup
Securely braces door
Not showy
lightweight
easy to store
Con:
Not really a con but just an fyi if you are living in an apartment or dorm make sure you are not violating any rules of your lease, or that you will not be obstructing a maintenance worker or inspection crew from coming into your room, since even with the key opening a door braced by this will be difficult and destructive.
