VK-Lite Installation Step 1: Preparation VK-Lite System Installation Example Calculate how much free hard disk space will be required for the storage server from the recording conditions to ensure that the system can operate stably. The amount of hard disk space required can be calculated using the following formula. Required free hard disk space = No. of cameras x Video data size x Recording frame rate x Video retention period (sec.) = 4 x 50 x 1 x (60 x 60 x 24 x 14) ~ 291000000 B ~ 300 GB The amount of free hard disk space required is therefore over 300 GB. However, this value does not include the space required in the system area. Note Do not use an external hard drive to store recorded video data. The video may not be recorded properly or the data may be corrupted.
