从去年以来，市面上出现了多种行车记录器，可以方便地装在风挡玻璃后面，通过摄像头实时录制车辆的行驶状态，并将视频文件自动复制到储存卡或U盘内。不少细心的车主自费购买了这种记录仪，以便在万一发生交通事故后可向警方提供更加真实准确的信息。
类似的行车记录器动辄卖到上千元，但目前已有部分IT公司开发出更加经济实惠的解决方案——在智能手机上装入特殊软件，利用手机内置的硬件实现行车记录器的功能。
亚洲某知名GPS制造企业日前已为iPhone4手机推出了专属软件，只要花2.99美元即能从苹果专属的App Store网店下载使用。这套软件搭配iPhone4的录像功能，除了可在驾驶时拍摄行车过程之外，还可随按随录，并自动保留最后15分钟的视频记录。此外，用户可以方便地在手机上播放或删除已记录文件，或者将文件复制到个人电脑上。
相对于专业行车记录，这种手机软件的功能虽然还不够齐全，但却足以应付日常之需，而且购买成本低得多。（文/云鹏）
