安全相机镜头---如何平衡质量和数量?

大多数安全摄像机已连接到 硬盘录像机 要么 NVR的 其具有用于存储安全摄像机镜头的硬盘。而质量和数量问题就会出现。用户可以拥有安全摄像头镜头的一兆字节存储空间,但如果多台摄像机工作在一个好的分辨率 - 例如1920 x 1280 - 每秒25/30帧,用户必须在一周以内删除录像。
Most security cameras are connected to DVRs or NVRs which have hard disks for storing security camera footage. And this is where the question of quality versus quantity will pop up. Users can have a terabyte of memory storage for the security camera footage but if several cameras work on an okay resolution–such as 1920 x 1280–at 25/30 frames per second, users have to delete recordings within one week or less.   Since lower settings can allow to store security footage for longer time, most users would consider it overkill to run their cameras at higher resolutions and on 25/30 frames per seconds. Please don’t use the lowest possible settings, especially if you ever hope to use the security system to identify a burglar or robber. A video recorded in poor quality won’t help you or the police identify a culprit.  The purpose for setting up a security system will help users determine an appropriate balance between quality and quantity for the surveillance footage. As a closing tip, if you are going to choose for lower video quality, consider placing your cameras in places which can best capture potential culprits’ faces. Another effective way to balance the quality and quantity is setting up motion detection record, then, the security system will only record when there is movement in the monitoring erea.  All MVTEAM IP cameras and hybrid dvrs support motion detection record. If you are using MVTEAM cctv products, please check below posts to know how to setup momtion detection record.
由于较低的设置可以将安全镜头存储在较长的时间内,因此大多数用户会认为以更高的分辨率和每秒25/30帧的速度运行摄像机的过度使用。请不要使用尽可能低的设置,特别是如果您希望使用安全系统来识别防盗或强盗。记录质量差的视频不会帮助你或警方识别罪犯。

建立安全系统的目的将帮助用户确定监控画面的质量和数量之间的适当平衡。作为一个关闭提示,如果您要选择较低的视频质量,请考虑将您的相机放在最能捕捉潜在的凶手面孔的地方。平衡质量和数量的另一个有效方法是建立运动检测记录,那么安全系统只会记录监控区域的运动情况。

所有 MVTEAM IP摄像机NVR的硬盘录像机 支持运动检测记录。如果您正在使用MVTEAM cctv产品,请检查以下帖子以了解如何设置运动检测。
