Network Attached Storage (NAS) or Network Video Recorder (NVR)
Network Attached Storage (NAS) is a type of storage that is connected to the local area network using a standard Ethernet connection.
NAS storage has its own IP address and may be used to store different file types, not just the images and video footage from cameras. Like SD cards, NAS is very reliable and reasonable primarily because they also use standard storage for LANs.
On the other hand, a Network Video Recorder or NVR is used only for security camera’s recordings, but functions similarly to how NAS functions. The difference is that NVR uses embedded software to record videos, while NAS can use the software provided by different manufacturers.
When opting for NAS storage for security cameras, be sure to consider how strenuous video recording can be at times. A network storage drive is different from a desktop computer’s hard drive that spins only when something is being written and read to it. NAS often just keep spinning even when it is not reading or writing. NAS continuously write onto the hard drive when used for recording, which could be overworking it. Be sure when purchasing a NAS that it is specifically designed for use with video surveillance. Moreover, ensure the hard drives are properly sized for video recordings. Your camera’s manufacturer can assist in figuring out the required size based on your needs of the frame rate, resolution, and time duration.
One advantage that NAS has over SD cards is the ability to record feeds from different cameras and have a bigger storage capacity, allowing storage of longer footage periods.
Disadvantage: Like SD cards, NAS are typically located inside your premises, which means that there is a possibility that thieves or a rogue employee can find it and destroy the video recordings. There is also the risk of NAS being disconnected from the network, which means there would be no video footage.
