Question
Why is VDV3 Series' IR range inconsistent?
Answer
All VDV3 use the exact same IR LEDs. The main reason why different VDV3 models have different IR range is because of the sensor. As seen below highlighted in red, different VDV3 models use different sensors (such as Super Low Lux and WDR Pro), and the IR distance is determined by the minimum Lux acceptable for each sensor. The 1.3MP model’s sensor has the lowest/best illumination acceptance, so they are able to see further than other sensors when using the same IR LEDs, whereas the Super Low Lux and WDR Pro models have higher/worse illumination acceptance so they are not able to see as far as the Super Low Lux or 1.3MP sensors.
Therefore, the IR range for VDV3 can be classified as below:
