If you want to install a video surveillance system in your home or place of business, there are plenty of things you need to think about, such as what types of cameras you need, how many cameras you’re willing to buy, and how you’re going to network everything together. However, as modern security cameras transmit digital video, you’re also going to need a video storage solution.


Internal Storage


When it comes to recording video from security cameras, there are several different options you can choose from – and these options often rely on how large your security network is. For just a single camera, or for systems that feature just a few cameras that aren’t on all the time, a simple solution such as a digital video recorder (DVR) built for security systems is likely your best choice. A security DVR works in the same way that your cable or satellite DVR works; there’s an internal hard drive fitted to your device that allows up to a certain amount of video to be stored indefinitely until either that internal drive runs out of space or an operator chooses to delete old footage.


Expandability Through External Storage


For larger systems, or for users who want better up time on a smaller system, data requirements are going to increase. In a situation where you have many cameras operating all at once or even just a handful of cameras operating 24 hours a day, you may need to consider an external storage option. Most security DVRs support expansion of their storage space by connecting an external hard drive to provide additional recording time. External drives come in several different storage sizes and can be interchanged when one drive becomes full, allowing an operator to review the footage from a full drive on a separate device while the DVR continues recording camera footage on the new drive. External hard drives are also durable, portable and easily secured, as they can be placed in a safe or otherwise kept out of harm’s way to safeguard security video footage, short of physically stealing the hard drive or destroying it.


Cloud Storage Options


When it comes to large-scale security systems with dozens of cameras all running concurrently around the clock, in most cases this will require a cloud storage option. Cloud storage involves transmitting video to an off-site location over the Internet for remote storage, usually in a secure facility with near-limitless amounts of storage space. While this does expose security feeds to hackers since the security system is no longer closed in the same way that an internal or external storage system is, the flexibility of the increased storage space – and the cost-effectiveness of large-scale cloud storage plans – make these options attractive ones for very large organizations that need to record an amount of security footage that would be impossible to store locally without a large amount of time and expense.
