How to connect IP-cam on a local network?
You will need the following components: computer, switcher, network cameras, and LAN Ethernet. There are also options for wireless connectivity.
Step 1: Identify your needs
- Do you want to use the camera only indoors? Or for outdoor use?
- You want a camera with a fixed angle or variable, which allows you to remotely pan, tilt or zoom?
- You will need the extra options, such as motion detection, alarm notification, camera power over Ethernet, audio?
- You want to just watch, or also to record what is happening?
- You want to protect the camera from external influence?
- Determine how many cameras you need for your needs.
Step 2: System requirements
If your building has not yet laid a local network, which allows you to simply include a network camera in the network output, you'll need the following equipment:
- Switcher, which will serve as the central connection point between your network camera and your local computer
- At least two cable Ethernet: one to connect your network camera with a switcher and another to connect the local switcher with your computer.
Step 3: Installation
- Connect all devices to each other through the switch
Step 4: Assign IP address for the network camera.
- You must assign an IP address for your network camera so that you can access it via IP-browser on your local computer. You can choose between automatic and static address IP. Static IP address is recommended, because you do not have time to search every IP-address of the camera.
To install the IP-address of Network Camera. You can use the software on the CD-ROM that comes with the product, or can be downloaded from the manufacturer's website or by using the method of determining the protocol addressed the utility ping. In any case, all the information you find in the manual to Network Camera.
Step 5: Complete the installation of network cameras.
Once the IP address was assigned, you can open IP-browser on your local computer and enter in the address field of IP-address of the network camera. For new visitors to the IP-browser Internet Explorer, the browser will ask if you want to download the program to work with the camera. This program is mandatory in order to watch video from the operative video server or video. It also provides control for MPEG-2, MPEG-4, audio streams, motion detection and pan / tilt / zoom in the browser window. (Other IP-browsers may have native support for video streaming and do not require additional components.)
How to get access to IP-cam via the Internet?
Example: Once you get the picture already with IP-camera to your computer, you decide that it would be nice to be able to access the camera anywhere there is Internet access. For example, a shop owner, you want to control the actions of the store from your home, instead of having to attend every minute in the workplace.
Step 1: System requirements
If your building (where the camera should be located) is connected via Ethernet to the Internet Service Providers (ISP), simply set up an account, include a network camera to the switcher via the network output, and you should get for your network camera dynamically assigned public IP address. Follow the installation teams for the network camera.
Special software or utility to an IP-camera will be useful in identifying the addresses of IP. As the designated IP address can be changed by your Internet service provider (due to limited supply of addresses IP, shared among its clients), learn how you can assign to a particular camera IP-address you will be able to Shage4 below.
If your building is not equipped with access to Ethernet, in most cases, you may need the following items:
- Broadband connections for asymmetric digital subscriber line (usually supplied by your Internet service provider) or cable TV.
- Broadband Router, which can still be called the Internet Gateway (broadband router allows LAN users to share a single Internet connection. It also serves as an interface between Internet services and local area network.)
- Switch, which allows different devices from the network to communicate directly with each other and allows the devices from the LAN to have separate IP-address)
NOTE: Most broadband routers have a built-in Switch, so separate equipment is not required
- Network camera
- Local Computer
- A computer for remote monitoring
Step 2: Assign the IP-address for your cam
- Because a broadband router is typically assigned automatically, the local IP addresses for devices of local network IP addresses are properties change. Static (permanent) IP-address is recommended for network camera. To assign a static IP-address, find a range of IP-addresses of the router, which, for example, can range from 192.168.0.2 to 192.168.0.35.
If you want to use IP-address out of range, type 192.168.0.100, as a static IP address for the camera is likely that you will not risk that your device will conflict with other devices that receive automatic address. - Set the IP address for your camera can be done in three different ways, as described in the manual camera. Once the IP address assigned, set the subnet, and gateway (this information may be obtained from the router) and configure the camera settings: password registered users for restricting access to the camera.
Step 3: Port Readdressing
- Broadband Router, as mentioned earlier, provides an interface between Internet services and local area network. The router receives the external IP address from ISP and distributes the internal (local) IP-addresses for devices on the LAN.
To gain access to the network camera, constantly being in a local network, you must identify the external IP address of your router (see the manual of your router) and configure your router so that the external IP address was sent to a static local IP-address of Network Camera.
This process is called an open port, that is, when you type the external IP address of the router from any networked computer, the Internet determines the location of your router in turn forwards your request to the local address of IP, which is assigned to a network camera.
- Start the IP-browser and enter the built-in IP-router's page through the entrance to the pages of the router configuration.
- Find the menu item "Port Forwarding" (or similar), with the table around as shown below:
Since the camera sends its video via HTTP, you must configure the HTTP service as follows:
- Save the configuration in the router and leave the configuration page. Configuration is done. Any requests that reach the external router's IP address on port 80 will now be sent to the IP address of the camera: 192.168.0.100.
- If you want to make accessible over the Internet more than one network camera, you should use additional (unofficial) ports in the router, such as 80xx and associate them with a network IP address of the camera.
Step 4: What can you do if your ISP changes often Dfi external IP address
- Create an entry in the DNS that serves and register domain names (eg http://www.webcamoff.com/, etc.) and attach it to the external IP-address, that is, each domain can set your network device ie its IP-address. Whenever the IP-address of the router will change, it will automatically be registered with the DNS, in order to update your IP-address so that you are at the same address have the opportunity to contact your network camera.
- Most broadband routers has native support for DNS, type http://www.dyndns.org/.
- Another alternative: You can buy or rent a static external IP-address from your ISP (Internet Service Provider).
How to use IP-based cameras to build IP-Surveillance system?
Effective way to enhance security systems in construction, factory, hospital or university campus is to use the existing infrastructure:
- During the day, the guards watching the monitor in the control room
- At night and on weekends, the observation can be executed remotely on a central monitoring point, serves a number of companies
- Built-in motion detection can trigger an alarm and start recording the alarm event
- In case of emergency, the head security officer can view the images on the closest to him udalennocherez PC or Internet connection.
Images can be stored in a computer in the enterprise or the server of your internet service (ISP). Storing images in a remote place of the provisions eliminates the risk that an intruder will destroy evidence of crimes. The cameras can also send images automatically host computer or host computer itself can retrieve images from the cameras.
If the main computer is running Windows, you can use special software designed for network cameras. The program can display the picture in real time, or work with archives. When the term storage of video images is, for example, two weeks, the program automatically deletes them.
