Frequently Asked Questions

How does DVR recording work with wireless cameras?

The HDVR74W records monitor displayed vision to Micro SD card (up to 128GB, not included) in H.264 MP4 format, capturing whatever appears on screen including single camera view, dual split screen, or quad view display. Recording continues in loop mode, overwriting oldest footage when card is full. This provides journey documentation including all camera angles for incident evidence, insurance claims, or fleet management purposes.

What is the actual wireless range in real-world conditions?

The camera's 120 metres line-of-sight range is the maximum distance in open conditions without obstructions. Real-world range depends on vehicle structure, metal interference, and mounting positions. Typical effective range of 20-40 metres covers most vehicle applications including trucks with trailers, caravans, or motorhomes. The FHSS modulation and 20dBm transmitter power ensure reliable signal penetration through typical automotive installations.

Can I view and record all 4 cameras simultaneously?

Yes, the quad view display shows all 4 wireless cameras simultaneously in split quadrant layout, and DVR recording captures the entire screen including all displayed camera views. This enables comprehensive journey recording showing complete vehicle perimeter. Alternatively, single or dual camera views can be displayed and recorded based on preference or operational requirements.

How does 0 Lux with 4 IR LEDs perform in complete darkness?

The camera's 0 Lux minimum illumination with 4 infrared LEDs provides clear visibility in complete darkness. The IR LEDs emit invisible infrared light that the CMOS sensor detects, delivering usable images during night-time operations, underground parking, or unlit loading areas where no ambient lighting exists. The 81dB dynamic range and 38dB signal-to-noise ratio ensure clear image quality in challenging lighting conditions.

What Micro SD card is recommended for DVR recording?

Use Class 10 or UHS-I rated Micro SD cards up to 128GB maximum capacity for reliable DVR recording. Higher-speed cards ensure smooth H.264 MP4 recording without dropped frames. A 64GB card typically stores 8-12 hours of footage before loop recording overwrites oldest files. Format the card in the monitor before first use for optimal compatibility and performance.
