How can I find out which cellular devices, operating systems, and cellular modems are supported by SerVision products?

List of cellular devices and operating systems that are supported by SerVision client applications, and cellular modems that are supported by SerVision video gateways, can be found at the Supported Accessories page under Resources. It is recommended that you consult with this list before you purchase any devices. This list is updated frequently.

Which types of cameras are supported by SerVision systems?

Only analog cameras are supported. Due to the proprietary and high ratio video compression protocols in our system (which enables high-quality video streaming over 3G networks), the SerVision video gateway must perform the Analog to Digital conversion by itself, otherwise the resulting outcome is very blurry, because the video is being converted twice. Since IP cameras provide a digital feed, they cannot be used.

Under what circumstances do I have to use the SVProxy server?

SVProxy is used when the video gateway does not have a publicly-accessible IP address (which is usually the case in most cellular networks). Both the video gateway and the client application must be configured to use the proxy server. For additional information, please refer to the unit’s configuration guide, or contact SerVision’s technical support. SerVision maintains several free-of-charge SVProxy servers globally which can be used in smaller projects.

When should I upgrade the DVR firmware or the client software?

SerVision releases new versions of firmware and software on a regular basis. The new versions contain bug fixes as well as added features. It is best to consult technical support about the advisability of implementing a specific upgrade. In any case, you should always be sure to use an upgraded version that was approved for release, and not a non-release version. The most updated versions can be found at our Downloads Page.

Who should I contact in case a system was supplied without some of its components, or some of the components were defective?

Contact technical support at support@servision.net. In your message, indicate which parts are missing or defective. If parts are defective, it is recommended that you attach photos of the defective parts. You should receive an answer to your e-mail within one business day.

What should I do if the system is not functioning properly?

Attempt to solve the problem using the user manuals and this FAQ. If you cannot solve the problem in this way, contact technical support. Please DO NOT send a video gateway to SerVision for servicing without contacting technical support first and receiving an RMA number.

How can I tell whether a Video Lost error message is caused by a problem with the video gateway unit?

The easiest way to check this is to switch the cameras connected to the unit so that they are connected through different connectors. Even if only one camera is connected, you can do this if the unit has more than one camera connector, by connecting the camera to the other connector to test it. If the “Video Lost” message follows the camera to its new connector, the camera is probably the problem. Check that its power supply and connectors are working properly. If the Video Lost message remains on the same connector, the video gateway unit may have a problem. Contact technical support.

Common error messages in SVMultiClient

Server was disconnected from proxy: this means that the client application had successfully connected to SVProxy, but was unable to find the unit specified, probably because it’s not listed or connected to it. Check that your unit’s configuration is accurate and that the unit is online and connected to proxy. Alternatively, check that your Host/IP settings in SVMultiClient are correct and specified exactly as specified in the unit’s configuration.

Socket Error: If you’re using SVProxy to connect to the video gateway, this means that the client application did not reach the proxy server at all. Make sure your proxy settings are accurate, or make sure your firewall permits outgoing connection to the proxy’s IP address and port. If not using the proxy (in case your unit has a publicly-accessible IP address), make sure the IP or hostname is accurate and that the unit is actually online.

Insufficient Resources: This error message indicates that the video gateway does not have enough resources available to connect to the client application. Typically, this occurs when a number of clients are already connected to the video gateway. In order to connect, you must find out which other clients are connected to the video gateway, and close the connections of one or more of them.Note: In the MultiClient, double-click the name of the video gateway in the list from time to time to see if the problem has been solved. If it has, the error message will be removed and the connection will be established.

No connection could be made because the target machine actively refused: This usually means that the machine is reachable by Ping or is registered on SVProxy, however SVMultiClient was not able to get a response on the port specified. Check that your IP/Host and Port numbers are correct and try again.

How do I add a video gateway to the list in the MultiClient?

Before you begin, make sure you have the following information about the video gateway you want to add:

– IP address or hostname of the unit
– Port used for video access
– User name and password for client access

If the connection to the video gateway is implemented via a proxy server, you will also need to know:

– IP address or hostname of the proxy server
– Port used to access the proxy server
– Name of the unit as it was defined on the proxy server

Once you have this information, you can add the video gateway to the list in the MultiClient as follows: At the bottom-left of the screen, click Add and the New Gateway dialog box opens. Fill in the connection details for the video gateway and then click Connect.

Note: If you are connecting via a proxy server, in the New Gateway dialog box, in the IP/Host field, enter the name of the unit as it is defined on the proxy server. In addition, you must configure the proxy server settings. To do so, click Advanced and enter the proxy settings in the Proxy tab
