It USES an infrared sensor and wireless door magic sensor detection, bee tangible traditional window to guard against theft for intangible, fire escape to provide convenient. And equipped with smoke sensor and leak burning gas sensors, realize the fire prevention, prevent gas leak role, multichannel and video: but in monitoring the multiple signals from one of the few road on all video, image quality and monitored show the same, and realtime continuous, every road all can reach the 25 frames per second. System can cycle storage, automatic will the earliest can abandon data and new data to delete replaced. Alarm video function: external sensor and alarm connection, may realize the alarm linkage video. Save hardware cost, reduce the system to the occupation of the resource. Flexible, convenient and video data shows the function inquires. But according to time, place or lens inquires the has been recorded data, the rapid feedback, displayed on the screen. Did not affect the ongoing monitoring system and video etc. Function. Operation log inquires the function, the user can through the query system recorded logs to get ever conducted operation records, the convenie
