How Long Do Security Cameras Keep Footage?

Many people wonder how long security camera systems hold onto footage. There is no single answer because different factors affect this duration. How long footage is kept will depend on the number of cameras recording, space available, resolution of footage, and purpose for recording the data.  Mammoth Security Inc.

Usually, the amount of time is dictated by the amount of recording space available, which is impacted by the quality of footage being stored. As a rule of thumb, homeowners hang onto a week’s worth of footage while businesses are expected to preserve at least a month’s worth. Read on to learn more about how long security cameras keep footage; this article will handle situations where footage is saved on the camera and where it is connected to an external recorder. 

What Happens To The Old footage?

Here is precisely what happens with the older surveillance footage whenever the recording space is no more. The latest footage automatically overwrites the oldest footage when you use a hard drive, an SD card, or a recorder. This implies that the storage that you have when it runs out after the specified duration of time, at any one point, you will tend to have footage of that specific duration of time. This is the easiest way to deal with a full hard drive and is also efficient. You can manually delete older footage by adjusting the NVR’s web interface setting.

Saving Footage To A Camera

Most security cameras have a slot for storage using a MicroSD card slot. The H-Series cameras can save up to about 128GB of storage as a general rule, whereas the Uniview cameras save storage of about 256GB. You should note that not all cameras support edge storage.   Whenever a security camera only records footage to a MicroSD card, it does not usually record at all times. They are mainly used to record events like line crossing detection, motion detector, etc. The amount of activity that is being recorded by your cameras determines the amount of storage kept on the cameras. When the recording schedule is busy, you may be able to store a day or two with your storage, but when you are not busy, you could extend it to even a week or even a month without exhausting your storage space. SD cards come in handy if you want to set up a standalone camera or even if you have a full surveillance system since this way, you will always have a backup if something happens to your NVR or its hard drive.

External Storage

The footage for the entire surveillance system is stored on an external recorder. In IP systems, they are known as network video recorders, while in analog systems, they are known as DVRs or digital video recorders. Recorders may at least have one hard drive installed, while other larger models can have as many as up to four hard drives. Always remember that the storage space you will save depends on the size of your hard drive and the resolution of your camera.

You can also choose to hold on to your surveillance videos for more than a week, and that’s no issue if it makes you feel more secure.
