Caught In Camera

Offsite Backup of Recorded Camera Footage

Our macOS CCTV software SecuritySpy saves all recordings to a local drive. By default, Mac’s internal drive is used, but you can specify any other drive (s) you want to use for this purpose, for example, an external drive connected by USB or Thunderbolt or a NAS (Network Attached Storage) drive on the local network.

Modern drives are very reliable, and for most users the small chance of data loss due to drive failure may not be too relevant. However, this could be more of a concern for more critical commercial applications, plus there is also the possibility that an intruder could damage or steal the drive.

To minimize the chance of data loss, there are a few basic steps that users can take, for example using only high-quality drives from reputable manufacturers, securing drives with anti-theft devices, or using multi-disk RAID disk setups that provide fault-tolerance.

One further method to prevent data loss is to set up an automatic offsite backup for the most important captured footage, so that this can be retrieved if the primary storage drive is compromised. There are a few ways to do this:

Use a cloud service such as Dropbox

Once Dropbox is installed on your Mac, the setup for this in SecuritySpy is very simple: for the most important cameras, set the Dropbox folder as the camera’s capture destination, under Preferences – Cameras – Setup in SecuritySpy. Dropbox will then automatically upload all captured files that SecuritySpy saves to the Dropbox folder.

  • Advantages: easy setup; reasonable cost up to 2TB storage; Dropbox handles all file management to keep the server synchronized with the local Dropbox folder.
  • Disadvantages: the Dropbox folder resides on the drive system, so you may need to have a significant amount of free space available on this drive for this to work well; since the cloud space is synchronized with the local space, you cannot have a different length of history at each location.

Use an FTP hosting account

There are many providers that offer this, including most web space providers. Once you have opened an account, you set up the server under Preferences – Uploads in SecuritySpy based on the FTP access information obtained from the FTP account provider. Then, you can use the “Upload” options under Preferences – Cameras – Continuous Capture and / or Preferences – Cameras – Motion Capture to choose which files to upload from which cameras.

  • Advantages: generally low cost.
  • Disadvantages: some users find the setup difficult; there is no automatic server file management – removal of old files from the server must be done manually.

Use an Amazon S3 account

Once you have opened an S3 account setup is very similar to the FTP setup described above: you obtain the access details from Amazon, enter them into SecuritySpy, and choose which files to upload.

  • Advantages: reasonable cost; relatively straightforwards setup; the server can be configured to automatically remove old files, independently from how old files are removed from local storage.
  • Disadvantages: Amazon charges per GB of data storage, whereas Dropbox and most FTP providers charge a fixed fee for a certain fixed amount of storage. Therefore, S3 may be cheaper for some users but more expensive for other users, depending on how much space is used.

Amazon S3 Setup

Overall, Amazon S3 is the solution that will be suitable for most users, due to its combination of ease of setup, flexibility, and reasonable cost. Here is how to set this up in SecuritySpy:

The first step is to open an S3 account. Next, go to the Identity and Access Management (IAM) area of ​​the dashboard, and create a new user, as shown here:

AWS IAM user

The user should have the following parameters:

Access type: Programmatic
Permissions: Attach existing policies directly
Policy name: AdministratorAccess

When the user has been created, you will be provided with an “Access key ID” and a “Secret access key”, which look like long strings of numbers and letters. Make a note of these two strings.

Next, go to the S3 Management Console and create a new bucket. A bucket is simply a container of files, just like a folder. The bucket name can be anything you like, as long as the name hasn’t been taken by another user.

Then, in SecuritySpy, go to Preferences – Uploadsadd a new server, and enter the access key ID, secret access key, and bucket name.

Click the “Test” button, and you should see a message that the file was uploaded successfully.

Use the “Upload” options under Preferences – Cameras – Continuous Capture and / or Preferences – Cameras – Motion Capture to choose which files to upload from which cameras.

Finally, to limit the amount of storage space used on the S3 server, you might like to configure S3 to delete files older than a certain number of days.

Final thoughts

  • While S3 has reasonable costs, it does charge per gigabyte of data, so the less data you store there (ie the fewer days’ worth of footage you keep on the server), the less you will pay.
  • When using FTP or S3, you can use the Upload Status window (available from the Window menu in SecuritySpy) to check on the progress of current file uploads.
  • The amount of data you can upload depends on the upload speed of your Internet connection (which is typically much lower than the download speed). Check the Upload Status window to see if files are being created faster than they can be uploaded.
