We installed the alarm system in less than a day earlier in the summer. It worked first time.

We had some issues with configuring the Hub although they were solved by a full reboot once we'd read the manual. We had some major issues mounting the door censors although that was because house was built by Bowey Homes and our doors don't fit properly. The words 'square' and 'true' are not in Bowey Homes' vocabulary.

The system has worked reasonably well ever since.

However, on one occasion when, for reasons we don't fully understand, the Hub would not connect to my phone. We think this was a problem with our internet connection, which may have dropped out. Our provider admitted said that there had been some issues with the service at around that time. I entered the house and attempted to disarm the system with the keypad. It would not recognise the key code and, after three attempts and twenty seconds, the external alarm began sounding.

I eventually managed to log into the Hub from my phone and was able to disarm the system. The App didn't alert me to anything at all and its logs suggested that nothing unusual had happened.

As a fix, we now wait until we have a reliable internet connection and test the system properly before entering the house. We've not had any further issues since then.

A great product, very easy to setup and use. The individual components are all robust and relatively simple to use and install.

The app itself probably isn't the best and has a couple of quirks but hopefully these will be ironed out in time.

Really decent kit for the money. PIR sensors went up really easily but door contact sensors can be a little fiddly to install properly. Very easy to set up. Everything pre linked as a system, but added a second door sensor. This was really simple to add to the system. Only downside is that the keypad is not the best quality. Wish I had bought the remote keypads. Pressing the buttons just feels like they aren't responding when they are because of the quality. The app is really straightforward and reliable. Really handy for when you go out and forget to put the alarm on. One thing that took us a while to realise was to make sure the door was closed before setting the alarm. If you try to set the alarm with a door contact open, it will not work.

Very good alarm system. Easy to install and works well from phone app allowing remote arming and me disarming. The key pad could be bigger for those with poor eyesight.

I found that Yale consistently scored highly for value for money and good build quality in my research for a smart home alarm system - the fact that the IA-320 and related models were a Which? Best Buy meant it was a no-brainer really! Entirely straight-forward to DIY install and just as easy to expand the system (I added an extra pair of door/window sensors and they synchronised first time). I replaced an old hard-wired system and didn't want the hassle of having to redecorate, so having an entirely wireless system was ideal. Used multiple times daily since installation - no issues with WiFi/not setting/false alarms/etc. Can arm and disarm from anywhere, which has proved useful too. Thumbs Up!

I've never had an alarm system before so bought this as a starter kit. I have to say I was sceptical about how good it would be for the money but I'm extremely pleased with it. The set up is fairly straightforward, particularly the room sensors; the door sensors are a bit fussy and don't look great but they work fine. If I were to expand the system, I would buy more room sensors and cover areas rather than doors. It found the wifi system and paired with Alexa without a problem although there was a little trial and error involved. It's easy to use and we turn it on an off almost exclusively by smartphone. It was a pleasant relief when I forgot to disarm but used Alexa just before it went off. Criticism: our keypad is a little inconsistent (but we mainly use the app); I'm not looking forward to changing batteries; erecting the exterior alarm bell is at the limit of diy. Pro: the part-arm is excellent; arming and disarming is easy; checking and changing remotely through wifi is excellent (you can get 3 miles down the road, check it and change it if necessary; the app and wifi applications make everything very convenient. I'm very pleased with this system. For the money it's really excellent and worth the head scratching while setting it up. I have already recommended it to friends and neighbours.

I installed the kit myself along with extra PIR’s and door contacts. Contacts and PIR’s were both in the house and in several outbuilding. The installation was easy enough although I used screws instead of adhesive pads. It took a while to get the hang of how the system worked but once I had it was fairly straight forward and logical. I found answers on line for most of the software problems I encountered. I phoned customer care regarding one problem. I got through easily and they were helpful and sorted it out quickly. I’ve only found one software design issue that has caused difficulty and I’ve written to Yale directly about it. I wanted to use the “part set” facility to set my outbuildings earlier than the house. This presents problems with “entry zone” doors. Once the outbuildings are set, going through a house “entry zone” door triggers the alarm even though the house contacts are not set.

Bought this for my daughter’s house. Fitted in about an hour. While I was installing my daughter downloaded the app and by the time I’d finished the installation was fully set up and working.

The ability to activate/deactivate from a mobile device is really handy and simple to use.

The simplicity of installing, as there are no cables to install, makes this a really good addition to any house as there will be no need for redecorating and no unsightly wires on display.

The sirens are very loud both inside and out, the external being high vis acts as another deterrent to would be intruders.

Overall a great product with everything you need, including batteries.

Very easy to set up with the instructions. Delivery and communication was very good from Safe.

The alarm kit was easy to install and reasonably quick to set up with the help of a Yale video on youtube. The app is not the most intuitive but you can ring customer service for help. It is very quick to arm and disable the alarm from the app so tend to use that more than the keypad. FYI, the siren is not set up to flash automatically (showing it is on), so you need to go into siren settings on the app to set the timing of this. I would recommend this as a cost effective alarm.
