If you want to set up recording and playback video, an internal hard drive is necessary. The system can not record via external USB hard drive.
Usually, a hard drive is very expensive. A 1TB hard drive is 70 dollars. Therefore, the same system with a hard drive and without hard drive has a big difference in price. We sell the system with hard drive and system without the hard drive.
As a hard drive is necessary for recording and playback, why do we sell a system without a hard drive?
The reasons are as below.
1. Some customers have their own hard drive and don't need an extra hard drive. They can save a lot of money if buy a system without a hard drive.
2. A few customers don't need recording or playback. He only needs to see the live view. He can save a lot of money if he buys a system without a hard drive.
