Can you still find the surveillance camera in the hotel corridor a month ago?

The video of the hotel corridor surveillance camera is usually kept for about one month.

If it is in public places like public roads, hotels, restaurants, schools, etc. , individuals have no right to take. If monitoring information needs to be retrieved, it is generally necessary to call the police and hand it over to the police for retrieval. These surveillance videos are generally kept for more than 30 days, but the specific time needs to be calculated according to the size of the hard disk and the number of cameras.

If it is in personal monitoring equipment, you need to look at the storage period of the monitoring video. For example, a 2-megapixel surveillance camera needs about 20G of space to record video continuously for 24 hours, so a 64G memory card can support a storage cycle of about 7 days. Similarly, a hard disk of about 1T can be stored for about 50 days. When the surveillance video is full, the earliest video will be automatically deleted, and a new video will be written to ensure that the new surveillance video can be saved.

Therefore, it is uncertain whether the hotel corridor monitoring a month ago can find the answer to this question, and it needs to be judged according to the specific situation. If you are looking for a surveillance video from a month ago in a public place, it is less likely. If you are looking for a video of a personal monitoring device a month ago, you may need to contact the owner of the device or find it by other means.
