DVR4QA – DIGITAL 4-CHANNEL RECORDER
1. Introduction
Thank you for choosing the DVR4QA. It converts analogue NTSC or PAL video to digital images and records them
on a removable hard disk drive. Digitally recorded video has several advantages over analogue video recorded on
tape. There is no need to adjust tracking. Digital video can be indexed by time schedule or events and you can
instantly view video after selecting the time or event. You can freeze frames, fast-forward, fast-reverse, slow-forward
and slow-reverse without image streaking or tearing. It can be used as a replacement for both a time-lapse VCR and
a quad in a security installation. Read the manual carefully before bringing this device into service.

is high ; when the disk is full it becomes low.
PIN 13: REC START: this pin allows recording triggering from an external device. Normally this signal is high. When
it becomes low, the device will start recording. When it becomes high again, the device will stop recording.
PIN 14: ALARM RESET: An alarm can be disabled by connecting pin 14 to pin 9 (GND). An external signal to this
pin can reset both the alarm output signal and the internal buzzer. Normally this signal is high.
