°  地网建设过程中，在隐蔽复原前应进行地阻测试，发现问题及时解决，避免重新整改的被动。干  扰 现    象 信噪比下降 图像上有“雪花”单项干扰 图像中纵、斜、人字形或波浪状条纹，即“网纹”电源干扰 图像中上下移动的黑白间置的水平横条，即“黑白滚道”脉冲干扰 图像中不规则的闪烁、黑白麻点或“跳动”如果图像有上表所述现象，应找到原因，采取措施避免或补偿。图像干扰的情况大概有这么几种，对应的现象如左边所示。接地不好会引起图像的干扰，所以干扰很大程度跟接地不良有关系。如果图像上有“雪花” ，说明整个系统信号传输链信噪比下降，应在各个环节寻招原因，如摄像枪、光端机没有妥善接地，视频电缆接头虚焊等。Ø 要选先进的市场主流产品,鼓励使用国内自主品牌产品。国外品牌必须进口关单,国产的国外品牌要有公安部一所或三所的检测报告和办理生产登记批准书Ø 一级监控中心，系统视频图像回放延时小于0.5s，二、三级监控中心，系统视频图像回放延时小于1.5s，省监控中心，视频图像回放延时小于3sØ  本地录像时视频帧率不低于25帧/秒，网络传输的视频帧率不低于15帧/秒Ø  普通的视频录像在硬盘/磁盘中保存15天，重要地段的监控录像可保存30天。突发事件或有案件发生的录像需要发送在监控中心NAS进行长期保存或备份Ø 存储的历史视频数据要求进行防篡改处理，例如增加数字水印或者数字签名，使之可以作为证据使用"}
