The house was stolen, but the police said that the technical appraisal lock had not been opened. Now I'm worried that thieves will come in and hurt people.

1, remote monitoring. The mobile APP can connect that kind. Convenient for on-site inspection.

2, install invisible monitoring, which can be stored for more than a few months. The hard drive should be bigger as evidence.

3, change the smart lock, the current mechanical locks are all mechanical rotating structures, which are easy to open. Smart locks can be unlocked by fingerprint, iris and facial recognition. It is important that the locking mechanism is electric. There are basically no solutions with keys. Unless you see it.

4. Install a motion-sensing camera at the gate, and someone will come in and take photos automatically. Evidence.

If I have a bad temper, I will install traps, high-voltage electricity, mousetraps, hanging ropes, javelins and so on.
