How long will the surveillance video of the property community be kept?

"Residential Property Service Standard (Draft for Comment)" is open for comments. According to the opinion draft, residential security monitoring equipment and facilities must operate normally for 24 hours to realize effective monitoring of the management area, and the picture must be complete and clear. "The storage of storage media should meet the configuration of image preservation time of not less than 30 days". This means that the owner's property has been stolen, and the property is required to provide the camera monitoring screen of the community. Residential property cannot be shirked for reasons such as "monitoring equipment damage".
