Alarm and video surveillance linkage function
Most of the respondents stated that the verification of the alarm situation is very important. A false alarm usually causes the security personnel to “false alarmâ€. Therefore, it is particularly important to determine whether the police situation really occurs. Combining with video technology has become the direction for many manufacturers to resolve the situation of the police and verify and develop new products. The author learned through interviews that many alarm systems already have the function of “image captureâ€. That is, the alarm system sends the alarm image to the alarm center at the same time as the alarm system to determine if the alarm scene is really a criminal. Some manufacturers attach an alarm recheck module on the main board of the alarm host, connect the video server to the alarm host, and upload the audio, video and data signals to the alarm center through the broadband network. The center can judge the alarm site according to the three signals at the same time. The actual situation, thereby greatly improving the reliability of the alarm system. There are also a number of manufacturers developed alarm host with "MMS" function: access to the camera on the alarm system and other image capture devices, on-site pictures can be transmitted through telephone lines, the Internet, GSM mobile network, etc. The captured picture can be supported by " "MMS" feature phone or computer reception.
SMS/voice function
The main purpose of adding SMS functions and voice communication functions is to ensure the absolute reliability of the system. With the SMS alarm mode, the alarm signal can be received anywhere, and the communication time is very short and fast. After the voice function is added, voice monitoring can be performed and the situation at the alarm site can be more accurately grasped. SMS and voice functions are mainly applicable to wired/wireless compatible systems and alarm systems that use telephone line networking.
Monitor/Intercom function
Wen Yingfei, an engineer at Shenzhen Mei'an Technology Co., Ltd., pointed out: “The alarm site monitoring function is after entering the correct password (two kinds of two-way monitoring password, one for the alarm center and the other for personal use. The alarm center password is usually in the system alarm In the next 10 minutes, it is effective to establish monitoring; while the user can establish monitoring at any time and in any state), within the alarm monitoring range, the voice of the offender and the crime of the crime can be clearly heard, such as walking around, digging,æ’¬ æ’¬ æ’¬ æ’¬ æ’¬ æ’¬ æ’¬ æ’¬ æ’¬ æ’¬ æ’¬ æ’¬ 并 æŠ¥è¦ æŠ¥è¦ æŠ¥è¦ æŠ¥è¦ æŠ¥è¦ æŠ¥è¦ æŠ¥è¦ æŠ¥è¦ æŠ¥è¦ æŠ¥è¦ æŠ¥è¦ æŠ¥è¦ æŠ¥è¦ æŠ¥è¦ æŠ¥è¦ æŠ¥è¦ æŠ¥è¦ æŠ¥è¦ æŠ¥è¦ æŠ¥è¦ æŠ¥è¦ æŠ¥è¦ æŠ¥è¦ æŠ¥è¦ æŠ¥è¦ æŠ¥è¦ æŠ¥è¦ æŠ¥è¦ æŠ¥è¦ æŠ¥è¦ æŠ¥è¦ æŠ¥è¦ æŠ¥è¦ â–² The center can record the scene of the alarm, and can also directly insert the SD card to record the actual situation on the site.There are abnormal movements, not only the alarm can be sent through the transmission network, the site can also send an alarm call, the alarm host can be realized with the dialed destination. Voice calls."
Remote control alarm linkage function
The function extension of the future network alarm host will be more extensive. The comprehensive alarm multi-functional information terminal products for the well-to-do level family will gradually increase, and the city's alarm operation system will gradually tend towards family service. Liu Changcheng, deputy general manager of Shenzhen Shengboer Industrial Development Co., Ltd., also pointed out: “Because of the speed of bidirectional data exchange, front-end hosts can give more powerful security management functions, such as remote network control and linkage to home automation equipment, along with With the soundness and stability of the 3G network and the diversity of services, people can control their own security areas more easily." Based on the bidirectional control function and the real-time nature of the broadband network, the network transmission module can monitor several or more simultaneously. The center sends events, but it can also send events to PCs, PDAs, and smart phones via E-MAIL. At the same time, you can log in to the alarm system via PC, PDA, and smart phone, and you can remotely set or control the alarm system and start or stop some functions. More flexible expansion and integration of other devices (such as smart homes, access control, etc.). â€
In addition to the above several functions, a professional also said that the future of the alarm host will gradually develop toward the direction of the smart terminal, the product not only has a general alarm function, but also has the function of information release and reception, that is, in addition to issuing alarm information, the alarm center also The property management content and notifications can be issued to the host. It is reported that this function has been applied in some high-end districts in China. In addition, more and more alarm hosts have information storage functions, such as support for SD card storage or SATA hard disk storage, etc. The purpose of the alarm host is to facilitate the detection of the occurrence of alarm events, facilitate the timely detection of alarms by the police center and the department, and to better serve customers. Provide services.
Network alarm host should have the function!
With the continuous increase of market demand and continuous development of product technology, the function of the network alarm host gradually expands, such as alarm and video surveillance linkage function, SMS/voice function, monitor/intercom function, and remote control alarm linkage function.
