LHV / LNR Series: Determining how long recordings will be stored

Multiple factors affect how long your video recordings will be saved on your LHV / LNR Series DVR / NVR before the storage space is full, or your recordings are deleted / overwritten by new recordings. Most security recorders are programmed to constantly overwrite the oldest footage to free up storage space for the newer live footage.

Each DVR / NVR has a specific storage capacity. Many DVR / NVR systems have additional hard disk drive (HDD) compatibility to expand the storage capacity. Check your product specifications sheet and user manual to determine if an additional HDD bay is available and the maximum storage capabilities of your system before attempting to install an additional HDD.

The following instructions require you to access your system using your DVR / NVR and a monitor.

To find out how much space your DVR / NVR system has:

  1. Right-click on the Live View to access the Quick Menu.
  2. Click Main Menu, and then click the Setting icon (Setting Icon).
  3. Click Storage > HDD Manager to view your system's free space and total storage space.

Recording Settings

Recording settings have a direct effect on the storage space usage. You can configure the recording settings on your DVR / NVR to maximize storage space by modifying the following:

  • Recording Resolution
    Lower resolution video recordings require less storage space, and enables you to store more recording time.
  • Recording Schedule
    The default setting for many DVR / NVR systems is to record all connected cameras in a Continuous mode recording schedule. This means that all of your cameras will record at all times, even when there is no activity to record. To maximize storage space, change your recording schedule to motion detection. By changing your recording schedule to motion detection, the system will record only when there is movement detected. You can also configure your recording schedule so that certain times of the day are recorded in continuous mode and other times in motion detection.
  • Audio
    Some cameras have audio capability. Recording audio in addition to video will increase the size of recordings. If audio is not required, disable the audio recording for smaller file sizes.
  • Frames Per Second
    Lower frames per second (FPS) rates decrease playback smoothness, but result in smaller file sizes.
  • Enable Hard Drive Overwrite
    When the HDD is full, it records over the oldest recorded video to allow space for the new footage to be stored. If you do not enable File Overwrite, you will need to manually delete files from the SD card or HDD, or insert a new card into the receiver when the HDD is full.
  • Recording Calculators
    Input the recording resolution, total number of cameras, number of days to record, and the FPS into the recording calculator to estimate how much storage space you require. If additional space is required, consider installing an additional HDD if supported by your DVR / NVR.
