It is most husejeres worst nightmare:

To come home from a wonderful christmas vacation to a broken pane or broken door and could see that there has been a burglary in one's own home.

And just the fear that destroyed the rest of december and having to fight with the insurance, you can see in the sale of surveillance equipment.

"Sales have exploded among the private sector. The danes have become more insecure, and monitoring equipment is now to pay," says Kasper Skov-Mikkelsen, who is a director in the Security industry.

Since 2015, the number of reviews about break-ins in the days leading up to christmas well enough dropped by 45 percent, but the numbers are still so significant in relation to the rest of the year, that the danes in higher and higher degree garderer with monitoring.

And then, play the work of the police also have a role.

"most of us have tried of the have a break-in and then at all of us also, that the police detection rate is around five percent, so there is a need to do something themselves," says Kasper Skov Mikkelsen.

DR have contacted Ebuyer and Elkjøp, who both confirm that they have sold more than twice as many surveillance cameras in 2019 as they did in 2018.

And, precisely, the product development has also, according to Kasper Skov-Mikkelsen, had an effect on increasing sales.

"It's just been a lot easier the whole. You can even install the equipment, and you can even buy it in everything from electronics stores to diy stores," says the director.

In 2018, between the 20. 24. december according to the national Police reviewed 388 break-ins in Denmark.
