Security cameras are an essential feature in our homes today. Camera footage is securely stored for future use. It cannot be kept for long because of high storage demands. Now the query is, do security cameras delete footage automatically?
Security cameras delete footage when they reach the maximum storage capacity. It happens for storing new information, videos, and other necessary data to sow updated scenarios. Following a series of steps, deleting footage manually from the cameras can be done.
This article will show the various reasons why cameras automatically delete their footage. However, this article will discuss all the necessary information related to the footage deleted and its causes.

Reasons Why Do Home Security Cameras Delete Footage
The cameras have an automatic setting that lets them delete footage after a while. Most of us don’t understand the reason why this happens. I share some of the causes why security cameras delete footage.
- Small Memory Space
There are CCTV cameras with a small, built-in storage space that cannot last long. DVRs, SD cards, or external hard drives may not have enough space to hold a large amount of CCTV footage. The best SD cards for use are the San disk Professional 12 TB hard disk.
- High Number Of Cameras
The amount of space available for storage becomes a problem when there are many CCTV cameras in a home. The more CCTV cameras, the more space they need. By storing footage in bulk, the duration of the process is significantly reduced.
- Footage Is Not Compressed
Another reason the storage space may be inadequate is the failure to compress footage. There is a need to compress footage (1) in the storage areas. When footage is compressed, the space it will need is significantly reduced. The compression, therefore, makes deletion of footage rare because there is sufficient storage.
- The Camera’s Resolution May Be Too High
The clarity and resolution of the CCTV cameras may be too high. When the configured resolution is high, the amount of space it will require is also high. Low-resolution cameras take up a minimum amount of space. So if the video quality is high, it can store some footage. And after it crosses the storage limit, the camera automatically erases the old footage.
- Low Hard Disk Storage
Usually, the security cameras have a 500 GB hard disk. When the particular storage is full of information, the camera automatically overwrites the footage to make room for new footage. It is also possible for cameras to delete footage according to the set configurations.
There is a setting on the cameras where you select when the cameras delete the footage. When the fixed time comes, it erases the data automatically.
- Rules And Regulations
There are some industries where it is mandatory to have footage for a certain period. These regulations are placed to protect the business or clients. In Banks, most of them are required to have footage for six months. This is necessary because of the high-risk business they are involved in.
5 Tips To Get Back The Older Footage From Home Security Cameras
Footage from cameras can be deleted after a while. This footage may be required by investigating authorities or by yourself later. You can use different methods to gain access to the deleted footage and use it. Below are some tips to get deleted older footage.
Tip 1: Restore Files Using File History
This is used in computers that use the Windows operating system. It is possible by searching for the file history feature in the computer. Open it and search for the deleted footage.
The system is designed to have a clear record of deleted files. This makes it easy to retrieve the document you seek. It is only possible to use this file history feature on windows systems.
Tip 2: Check In Storage Backups
Most CCTV cameras have a series of backups for their footage. Backups can be checked on DVRs, NVRs, FTPs, and the cloud. The DVR machines like the Annke 16ch 2TB DVR have a memory where you can get deleted footage. Cloud-based storage is the most modern method of storage of footage.
Tip 3: Go Through The Recycle Bin
This is where data is stored when deleted from the computer system. It holds some footage before permanent deletion is done. Check the recycle bin if you are sure it wasn’t cleared.
Tip 4: Obtain Third Party Recovery Software
This software can retrieve deleted footage from CCTV cameras. It can access the cameras’ storage and get the required recordings. The available software can be accessed online, where you purchase it for use for a specific time. Recovery software is highly effective as they are specifically developed for that purpose.
Tip 5: Contact Data Recovery Service Providers
Data recovery service providers are experts at retrieving data and footage from CCTV cameras. They are highly specialized and have vast experience in dealing with the retrieval of deleted data. Additionally, they can recover data from damaged cameras. Contact them, and the footage will be availed to you quickly.

Do Security Cameras Keep Footage Forever?
Security cameras can’t keep footage forever. This is because the ability to keep footage comes from the storage space available. Footage can only be retained for as long as the storage space is available.
Some cameras can store footage for a maximum period of 7 days, while others can last 90 days. The ability to keep footage forever is quite challenging to achieve because it depends on factors that are simply out of reach. It would mean having an unlimited amount of space available which is currently not possible.
How Long Does A Home Security Camera Store Footage?
This period lasts a minimum of seven days to six months. The period that a camera can store footage varies. The variation comes in terms of the storage capacity available. When the storage is sufficient, the footage can last for six months. If the storage is small, the footage will only stay for a week.
The length of the footage is also dependent on the number of cameras. The footage will probably last a short period when there are many cameras. In the case that the cameras are few, this means that the space available for use is more. The most significant contributing factor is the amount of space available for storage.
Is It Possible To Delete Footage From Home Security Cameras Manually?
It is possible to delete footage from security cameras. There are different ways you can delete footage, but it all depends on the type of storage that is in use. To delete footage stored on a DVR, press its delete button.
When the SD card is used, the best way is to access it manually on your device and choose the delete option. For the case of the Cloud, login into your cloud account and select the footage that should be deleted. This automatically clears all the footage chosen.
Where Is Security Camera Footage Stored?
CCTV footage can be stored in the DVR, NVR, FTP, SD cards, External Hard Disks, or in the Cloud. The type of storage depends on the number of cameras and the size of footage needed. Camera footage is highly sensitive and thus should be well protected.
The best storage for footage is cloud storage. Cloud-based storage is encouraged because it is less costly than other storage options. The cloud is also highly secure, and it offers a large amount of space for use.
Takeaway:
CCTV cameras have become very common in our homes for security reasons. This footage that comes from the cameras needs to be well stored for future use. The methods to access old footage have also been well discussed.
It is beneficial to the camera’s storage when they delete footage as it creates space. There is an option of deleting the records manually or letting the home security cameras delete their footage by themselves.
