Keep your home that little bit more secure with this Swann smart indoor siren. As soon as your smart sensors (sold separately) are triggered, it’ll set off an alarm to put the frighteners on any unwanted guests. This model will be good to go in no time as well – it’s really simple to set up, and doesn’t need a hub to get started, meaning you won’t have to decipher endless manuals to get it up and running. It’ll work with the Swann Security mobile app, so you can keep your system linked together, and is compatible with both iOS and Android operating systems too.
