Q: Bandwidth - one million high-definition monitor is affected by the network bandwidth limitations ?
A: The one million -pixel high -definition network camera because , in theory, will lead to greater stream , but because the snow noise is small, saving the stream , which reduces the bandwidth limitations . In addition, one million high-definition IP Camera usually have dual-stream technology, namely local ( LAN bandwidth is sufficient ) HD video recording , remote can be used according to the bandwidth CIF resolution monitor , so basically no network bandwidth troubles.
Q: price - high definition is not necessarily expensive ?
A: The general view is that : HD inevitably high price you pay . This is mainly because in the past , one million high-definition network camera mostly imported from abroad, the price is extremely expensive. But in recent years , the domestic one million high-definition technology continues to mature and to market , significant cost reductions , the price is much lower than the imported high-definition cameras , high-end projects , whether in the government or the low-end residential market, domestic digital HD network camera price is much higher than foreign firms , to bring low-cost high-quality high-definition security user experience.
Q: Illumination - how to solve one million high-definition camera at night or in low-light control issues ?
A: For a long time , illumination is plagued Megapixel network camera is a major problem . To make one million HD illumination achieve the best results , first of all have a large selection of lens F value of the lens , light-sensitive photoreceptor large area , such as 1/ 2 , 1/2.5 or 1/ 3, in the military industry also typically more large, but the civilian security monitoring usually consider the cost , mostly for 1/2.5-1/3 ' . APTINA companies such as the U.S. launch of the new 1.3-megapixel low salvation 1/ 3 ' sensitive , intelligent use of this device to be rapidly developed Illumination Wide Dynamic million high-definition camera , taking into account the clarity and illumination , especially in low-light effect, under the same control environment is far superior to analog cameras , this breakthrough will greatly accelerate the digital Megapixel IP Camera spread.
