This alarm system was incredibly easy to set up. Everything comes pre-paired, so all you have to do is pull out the plastic tabs that keep the batteries from draining during transit. You can stick the components up with the adhesive pads provided or use plugs and screws if you want something more permanent, I just used the sticky pads. The whole installation took me less than 30 minutes. Honestly, it took longer to get the ladder out than to screw in the outdoor siren! If your bundle includes a fob, it’s a brilliant little extra that makes arming and disarming the system so much easier, whether you’re coming home or heading downstairs in the morning.We’ve been dealing with a string of burglaries in the area, and they’ve been targeting back doors. Ours is very accessible, so I’ve configured the alarm to go off instantly with no delay if the door is opened. It gives me real peace of mind, and I sleep much better at night knowing it’s in place. I’ve turned off the motion sensors because I don’t want to have to disarm the alarm every time I walk into the living room or risk forgetting to rearm it during the night. For me, securing the doors is the priority, if someone tries to break in through a window, it would be noisy enough that the alarm wouldn’t even be necessary.At the end of the day, you can’t put a price on feeling comfortable in your own home, especially at night. Knowing you’ve got a good theft deterrent is priceless. Although, I’m not too concerned if someone does manage to break in. What matters to me is that I’d know about it right away so I can deal with them personally, rather than being asleep and unaware while my children are sleeping too.I can confidently recommend this to anyone. This is one of those items your gut tells you that you need, and you should always listen. Plus, the hub doubles as a siren, so it’s not just the outdoor one making noise. Together, they are incredibly loud, especially at night, when the sound would be insanely jarring, My kit also came with a dummy siren. Personally, I didn’t see the need for it, (AKA I didn't want to climb up the ladder again) so I gave it to my parents to use as a deterrent. Even though it doesn’t make any noise, its presence alone is likely enough to put off some thieves

The Yale Sync Smart Home Alarm system has two purposes. Firstly as a traditional "ring the bell" alarm and secondly as a smart alarm which notifies you on your phone and allows you to arm/disarm your alarm when you're out.As a traditional "Bells only" non smart alarm it is definitely worth 5/5. It was quick and easy to install, all the fittings were provided. I purchased additional sensors so I have installed 5 PIRs, 5 Door /Window contacts, the external siren and the keypad. All of these took under 2 hours to install (ignoring the external siren - it was raining, that was done separately the following day). The 'built in alarm' in the hub is 100db of loud and more than adequate alone, the second one is more of a deterrent than something that's required. I have successfully setup the part arm and full arm modes with ease.Being able to set multiple pins is a great idea, obviously however the more pins you have the easier it is to guess and your alarm is only as secure as your weakest pin. I have a pin for myself and then 2 family members have different pins so if they need to disarm it they can, but I will also know who has been in my house if they do.The only issue I have had is occasionally when using the App occasionally it says the 'hub is offline'. Which means I cannot get notifications or remotely arm/disarm the alarm. This is easily fixed by turning the alarm off and on again physically, just a pain.This is an issue with any smart device, whether it be blinds, bulbs, alexas, alarms or smart cars. Hopefully overtime this becomes less of an issue. This model is far superior than their old Yale Smart Home Alarm system and operates at a much better range and is more reliable.Ultimately it comes down to this: If you want a "Bells Only" alarm this is great, if you want an "alarm with notifications" this is good but not bulletproof. If you want the most reliable service possible you'll need to buy an ADT alarm with subscription and even then there is a slight risk of it going 'bells only'. For context, my setup throught ADT would have been £800 installed and then £40 a month £930 more in the first year and then £480 a year more forever... So I'd definitely recommend this unless you're a Jewellery store or bank.4/5 would definitely recommend for most people. Would be 5/5 if the hub never disconnected, however overtime the server technology should improve this, I'd say my hub uptime is around 95% from what has been monitored so far.
