One of the often underrated, dahua but the undeniable advantages of digital monitoring systems operating on the basis of the IP protocol dahua is the potential for system administration from anywhere in the world. Just consider one of many possible examples of this function - household spend their holidays in a remote part of the world, and who in this situation dahua at least once not consider whether you sure your home is everything okay? With the ability to remotely connect to a home surveillance system to dispel any doubt is child's play - simply access the internet at the hotel, internet cafe, via GSM or in any other way to connect to your home address, check the list of events recorded by the monitoring system and Forget the more worrying is unnecessary dahua thoughts.
To get such an opportunity, but you should meet certain dahua conditions. Of course, the key element is absolutely remote administration service for the monitoring system installed, but you can safely assume that any modern digital system present on the market supports this feature. It is in fact one of the elementary components of determining the success of the market system. The second and final piece of the puzzle is the knowledge of the IP address at which the available monitoring system will be discussed. Seemingly thing seems clear, however, at this point there is a trap. Without going too deep into the technical details, virtually 100% of cases have Internet access (at home, in the office, etc.) access to the Internet (ie simplification "outside") is not equivalent to access the Internet (ie, "outside '). Such behavior is understandable when you consider the degree of risk that is involved with each use of a computer with unrestricted access to the Internet through an unconscious person. The key term here is the public IP address, also known as external. Disposing of this particular type of IP address, and his knowledge is absolutely necessary for remote administration digital monitoring system. Home or office computers with access to the internet almost never have a static, unchanging public Internet address. In a very easy way to check what kind of computer has an IP address. To do this, use the command winipcfg, ipconfig and check the address in the Control Panel-> Network dahua Connections-> dahua Properties for Windows or ifconfig for family systems Unixes. IP address dahua beginning with 192.168, 10.0 or 172.16 is the address of an internal, invisible on the Internet. To find out the IP address which may in fact be visible your computer, you can for example visit http://whatismyipaddress.com/. There you will see the information, from what IP address merged. The resulting value will be different dahua from the address of the machine, because it will be the address of one of the routers our ISP. In addition, both the address of the computer and router may change every day, and even more frequently. Fortunately, this is not a serious obstacle in obtaining dahua remote access to our monitoring system, possible solutions to this issue can be found later in this article.
Consider the two most common types of Internet connection provided by the network service providers: Network osiedlowa - this term should be understood as a link in the form of Ethernet cabling. If the case should be quite simple - in fact paid to the service provider with a request to allocate a fixed, public IP address. In general, the address is obtained from the hand, sometimes this involves an additional, small fee, and must be in accordance with the instructions dahua of the monitoring dahua system to activate the remote access feature. In the situation, but if it was not possible to obtain the address, the solution is identical to that described in the next section. XDSL link - link using a modem, such as the popular Neostrada. In this case, to obtain a public IP address and it is virtually impossible dahua to be able to gain remote access to the monitoring system will be needed outside help. To do this, use the services of companies offering a dynamic name server, which is DDNS (Dynamic DNS). Free services offer this form of, inter alia, the site http://www.no-ip.com/ and http://www.dyndns.org/. Configuration dahua is reduced to give a name montoringu own system, under which it will be available on the Internet (eg mojdom.dyndns.org) and the current IP address, and then enable the use DDNS function in the monitoring system in accordance with the instructions of the system. Of course, you should pay special attention to setting a strong password to access the system, because after activating all the settings dahua your system monitoring will be allowed access to the administration panel from any computer connected to the Internet.
