考试监控漏洞:为什么传统CCTV无法胜任线上和考场测试


传统的顶置摄像头可以覆盖考场,但无法看到考生的屏幕,留下关键盲区,为作弊提供机会,并影响认证通过。

  • 屏幕作弊无法察觉

    天花板摄像头无法记录隐藏的浏览器标签、聊天软件或虚拟机中的答案内容。

  • 远程与混合考试风险增加

    异地笔记本需被监控,无需额外硬件运输。

  • 认证机构要求屏幕证据

    ISO 23988、Pearson VUE 和高校管理机构都要求屏幕录像,而不仅是环境视频。

  • 手动录屏工具无法大规模应用

    普通软件容易崩溃、占用带宽且无法与VMS关键字搜索集成。

  • 采集卡增加预算负担

    大批采集设备和字幕插入器推高成本,仍无法消除盲区。

4 个关键的考试级功能

双通道 ONVIF 录制

将考生的屏幕和摄像头分别作为 ONVIF IP 流进行录制,实现在 VMS 中逐秒同步回放。

 

加密签名的审计记录

带时间戳的高清视频可确保考试的完整性,为认证机构和高校提供安全、可验证的证据。

极速部署,无需人工干预

30 MB 的轻量安装包可通过 MSI、Intune 或脚本在数百台考试电脑上快速部署,无需更改硬件或停机。

 

隐私优先的架构设计

视频流不在本地保存,安全传输至现有 VMS,全面支持 GDPR 和 FERPA 合规。

DeskCamera 在教育与认证领域的真实成功案例

  • 认证与考试中心为 CompTIA、Cisco、Microsoft 及语言类考试提供屏幕录制证据,满足审核机构的认证要求。

  • 大学考试机房从一个控制室集中监控多个考场,实时识别抄袭或未授权软件。

  • 远程与混合监考将任何笔记本变为监控设备,无需邮寄摄像头即可保障远程考试安全。

  • 医疗技能评估护理与助产实验室同步记录生命体征模拟器与学员操作,替代昂贵的回放系统。

  • 图书馆与培训中心效率管理记录访客和预约系统的使用情况,优化运营流程。
