It is extremely essential and important to format SD, as the formatting ensures that HDD would have the required file system
format. Normally, select FAST FORMAT to format HDD. The unit will restart automatically after successful formatting.
FAST FORMAT is the same as quick format on PC.
SLOW FORMAT means checking the existence of bad sectors in HDD, the system will remember if there are bad ones
and will not write data in this place again.
DETECT HDD means it will make sure not to lose data when the HDD has physical damage(s).
Please Note: For HDD installation, follow the guidelines attached in the accessory box.
User default password is 22222222, andAdmin password is 88888888.
OPERATOR PASSWORD CORRECT indicates permission is limited to video and sensor menu.
ADMIN PASSWORD CORRECT indicates full access to SVA400L.
SUPER PASSWORD CORRECT indicates full access to SVA400L under the circumstances of lost
password and/or the MAC address has been modified.

9.3 Record Setup
Setup the related parameters for Recording:
Go to SETUP > RECORD > OPTIONS to setup the basic parameters such as video type, record mode etc., as detailed below:
Go to SETUP > RECORD > CHANNEL SETTINGS to setup resolution, frame rate, normal recording quality and recording quality
when there is an alarm, for each channel:
RES: Resolution standard is optional; it can be D1, HD1 and/or CIF. D1, HD1 and CIF refers to DVD standard, super VCD
standard and VCD standard respectively.
