Sensormatic CCTV cameras, how to join

Set up a WiFi camera

WLAN camera - simply installed

Wireless cameras are enjoying growing popularity, especially in the private sector. Many households have a wireless network anyway, so apart from a power socket, a WLAN camera does not need any additional accessories. Above all, you save yourself laying long network cables. It is not very difficult to set up and is similar for almost all models.

The standard case is described here: There is already a home network with WiFi and the IP camera should be integrated into it via a router. Instead of using a router, a camera with WLAN can also communicate directly with other network devices. In addition to the direct connection to a PC, a radio connection to a network recorder is also possible. The Hikvision DS-7108NI-K1 / W / M provides its own wireless network without a wireless router.

Requirements: Make a new IP camera accessible

For the initial setup, the WLAN surveillance camera is connected to the power supply and the connection to the router is established via Network cable here. A very short cable is sufficient for this - at first it's just a matter of getting access to the camera settings. The cable connection can be omitted later.

Depending on the model and manufacturer, the further course is slightly different. Basically, however, the configuration and later the consideration of the Live images from the PC only possible if the camera and computer are connected to the same so-called Subnet belong. Is in the camera at the factory DHCP activated, you share the DHCP server (this is the router) one dynamic IP address to. This is automatically on the same subnet as the computer. You can find this address in an overview in the router menu or you can display it with a scanner software (see below). Enter the IP address of the camera determined in this way in the address line of the browser and you will be taken to its homepage. A standard user name and password are requested there (e.g. "admin" and "12345"). You have to change these specifications later. If necessary, a plug-in for the browser has to be installed.

If DHCP is not activated, you must first assign a suitable IP address to the camera. At Hikvision, this works particularly easily with the SADP softwarewhich is contained on the CD supplied and available for download on the homepage.

After installation, the software scans the network for cameras and displays their current IP addresses. Here you select the appropriate entry from the list and enter the correct network parameters. As a "gateway" is the local router address enter a free address from the address range of the router for "IP Address". For example, if the router has the address 192.168.178.1 and the computer 192.168.178.30, you can simply try 192.168.178.31. It is only important that the first three groups of digits are identical on all devices, that the selected address is not used and is within the permitted range. By default, the numbers after the last point can be between 20 and 250 on many routers - there is always a free space.

Tip: On computers with Windows, you can find out the gateway and address of the computer by typing in a command prompt "Ipconfig" enters. What is then under "Standard gateway" must be entered in the SADP software as a gateway; what under "IPv4 address" is the computer's IP address. The possible IP address for the IP camera is derived from this by simply changing the last digit and entering it in the software.

Now all that is missing is the camera's password and a final click on “save”. If everything went well, the camera can be accessed via the browser as described above.

WLAN instead of cables

If the cable connection is established and the surveillance camera is activated, the configuration of the WLAN settings can be started. Before you start, it is best to write down the name of your own network ("SSID") And the passphrase with which it is protected against unauthorized access. These data can be found in the router's menu. If available, it is also worth taking a look at the Mac filter. If the filter is switched on, the router will not accept any new WLAN devices. This filter must be deactivated at least while the surveillance camera is being set up; it can be switched on again later (or you can manually enter the camera's MAC address in the filter, but that is unnecessarily much work).

In the camera menu, the settings for wireless networks are again different depending on the model. A menu item "Wi-Fi" or similar is available with every IP camera with WLAN. This menu shows a list of all networks within range. You click on your own network, enter (if not automatically recognized) the encryption type and the passphrase and save everything. If necessary, you have to tell the camera that from now on it should use WiFi instead of cables for data transmission. The corresponding selection of the "NIC" can be found in the TCP / IP settings. Settings for the camera's WiFi IP address and the gateway must also be made there, if they are not already correct. The same rules apply as mentioned above for the assignment of IP addresses. Computer and camera must have addresses in same subnet to have. Once all settings have been made, the cable can be removed and wireless communication can be started.

IP addresses: Static or dynamic, local and on the WWW

In most cases, routers assign dynamic IP addresses to the connected devices. This means that after a restart or a disconnection you may receive a different IP address than before. To avoid this, you can alternatively use a static IP address set (then DHCP is deactivated). This means that the WLAN camera can always be reached at the same address in the local network. One should not confuse local IP addresses with the address that the router has on the Internet. This public IP address in the WWW is usually dynamic and is assigned by the Internet provider. Access to the cameras from the Internet is possible without any problems using the services of the camera manufacturer, a DDNS service or a VPN.

Problems and solutions

For one WLAN camera test you simply call up the homepage in the browser. If the page does not load, only slowly, incompletely or unreliably, a systematic approach to isolating errors is necessary. If the IP camera uses WLAN, reception problems can never be completely ruled out, because radio technology is subject to many disruptive influences.

Error source no.1 the distance between the router and the camera is too great. Then either the use of repeaters to increase the range helps or you bring the camera and router closer together. If the devices have external antennas, a realignment can be enough. A similar error pattern with temporary dropouts arises when too many networks in the vicinity transmit on the same channel. This can be remedied by changing the channel in the router. It is important that a frequency range is selected that the camera also supports.

If these measures do not bring the desired success or if no connection is possible, you can briefly deactivate all encryption - just for a test of the WLAN camera. If everything works unencrypted, there is probably an error in the selected one Cryptology or the Passphrase in front.

Rarely does one react WiFi camera simply not at all anymore. Resetting to the factory settings should then only be the last resort, because all user settings will be lost. The instructions show how such a factory reset works. Often there is a small button on the bottom of the camera or under the dome that has to be pressed for 10 to 20 seconds. Before doing this, you should try restarting the camera by simply disconnecting it from the power supply, waiting 30 seconds and then reconnecting it. They are only reset if that doesn't help.
