Home alarm systems: how can I improve my security?

Peter has to move from his very secure high-rise flat and wants to avoid being burgled

I currently live in a high-rise flat, which is very secure, with CCTV, fob-controlled access and so on. Unfortunately, due to Grenfell, our block is being emptied for refurbishment. I don't know what type of property I will be offered, but I will have to provide my own home security system. Cost is not a major issue, because I will get a disturbance grant for the enforced move. But, as a pensioner, I wouldn't like to be saddled with a high monthly premium for monitoring. Any suggestions would be very welcome. Peter

Technology companies are selling a lot of new gadgets to increase home security, including smart locks, motion detectors, window sensors and digital cameras. Many are part of the trend towards "smart homes" with internet-connected doorbells, lighting, voice assistants and so on. Most of this stuff comes under the general tech-industry label of the internet of things (IoT).
