Shop for security cameras based on the amount of clarity needed at each camera location. If the target object is going to be less than 20ft away from the camera, there is no reason to record video higher than 1080P resolution. The higher the video resolution, the more DVR storage space it will need. If you're unsure about which camera resolution is best for your application, we suggest reading our guide on how to choose a security camera. It is common to use a 2K security camera for example, and record it at 1080P to save hard drive space.
Depending on whether your security camera recorder, it may support H.265 encoding. Compared to H.264, it can provide up to 50% savings in hard drive space. While that may sound great, keep in mind that setting all the cameras to H.265 might take a toll on the CPU of the DVR or NVR and slow things down a bit. We suggest using H.265 on 80% of the cameras in a system.
Frames Per Second (frame rate or FPS)
A substantial amount of video storage space can be conserved by setting an optimal value for the frame rate in FPS. For most uses, 15FPS is plenty. Some of our IP camera options are able to offer 60FPS, but that should only be reserved for views with fast moving action. For example, license plate security cameras require the best possible video to capture a moving vehicle.
If you don't need video to be recorded 24/7, it is easy to conserve space by setting a schedule for when each camera should be recorded.
Motion Activated Recording
Almost all security camera recorders offer motion detection. If you don't need 24/7 recording, enable motion activated recording to maximize video retention time. An IP camera system uses smart cameras that have video analytics for motion detection which can provide further savings of hard drive storage space.
