第三步:是否要有夜视功能 在走廊、监控门厅、过道、库房等光线比较暗的地方,可以考虑红外夜视功能的摄像机监控,需要注意的是,红外摄像机除专业夜视或特别订制以外,监控红外摄像机也需要现场有灯光辅助五指的条件下,红外距离会成倍缩短。现场如果为花园草坪,红外 效果更差。 第四步:是布线还是采用无线 除了昂贵的价格以外,监控无线网络确实省去摄像机布线的麻烦与不美观,监控但需要注意监控距离与障碍的问题。原则上水泥建材会缩短无线的传送距离,,金属材料则会完全遮蔽无线讯号, 发射器(在摄像机端)与接收器(在主机端)要远离其他的电器以避免干扰,如要采用无线网络,就要有负担2倍 以上价格的准备。我们建议除非必要,尽量使用有线传输
