1. site description:
To make sure the works go on wheels and the devices safety, the large Site need to monitor 24 hours every day. So adopt the video monitoring. The site need install HD network bolt camera,10 points, and the customer want night vision 80m(client’s requirement: purchase by himself)
From camera to local monitor room distance up to 1km,monitor room can monitoring the site hold time, can dispose in time when happened accident. In consideration of use the wired video monitor the wire will pull-apart by car. So take wireless video transmission equipment for remote wireless monitoring, wireless transmission multiple high-definition video images.
A total of 20 cameras, each lever has 2 cameras, each lever using two switch, so can use two cameras summarize a transmit. Between The control room and the camera have 1km range, when install wireless video transmission equipment requires the use of high back-end wireless receiver equipment for transmit and receive unobstructed and can receive multi transmitter signals. So use 1point to 3points, 1point to 3points, 1point to 4 points, achieve 20 roads transmission of video signals. The rear end, the use of the switch aggregates radio signal receiver, and finally into the storage device to a monitor.
2. Customer demand:
Establish an advanced video surveillance security management system is to strengthen the science building construction safety, improve project management efficiency, prevent unauthorized persons broke into the site, causing accidents and property damage. Due to limitations of the construction environment, equipment, materials, inadequate safety management and some employees of self-protection awareness is weak, is not suitable for traditional wired monitoring methods, but they must be installed on-site video surveillance system.
3. Wireless video monitoring project
According to the customer requirements, Our company provided a Digital wireless video monitoring system. Adopt the 5.8G frequency ST-58T8G and 5.8G frequency ST58T8G-N industrial wireless digital equipment
The front end of each lever transmit to monitor room, Adopt 1point to 3points, 1point to 3points, 1point to 4 points, achieve 20 roads transmission of video signals receiver, Switchboards summary, Transmission to the control room ,NVR storage, can watch by the monitor. The NVR can control the cameras rotation.
