How to find out how the home is monitored?

For recording equipment, the detection method is a bit complicated compared with camera equipment. Generally speaking, recording equipment will have a return function, and at the same time, mobile phone signals will be used. The way to find it is to use a speaker that needs to be plugged in, and then the quality is not too good because the shielding ability of this speaker is very poor. As long as someone is on the phone, the speaker will beep. Next, walk around the room with active speakers. If there is noise, there must be eavesdropping equipment.

At the same time, in order to prevent being monitored and reduce the occurrence of home theft and any unsafe incidents, we still need to install security monitoring at home.

However, first of all, from the appearance, there are different images such as long tube, sphere and hemisphere. However, in the modern home environment, people seem to prefer more fashionable and simple shapes.

Secondly, there are many choices for home camera lenses, such as 2.8 mm/4 mm/6 mm/8 mm/ 12 mm, and it is a bit difficult for people who are not familiar with monitoring to choose the appropriate lens focal length. So before buying, I will consult the technician which focal length is suitable for me. Generally speaking, the shorter the focal length, the wider the viewing angle range, but the shorter the monitoring distance.
