Frequently asked questions and answers



  1. Why the camera or Video capture device are not detected/found on the system even if I installed it
    Usually if the user has a camera connected the problem is solved by detaching and attaching the camera to the USB port.


  2. Why did the installation of .NET framework fail with error code '2'?
    The .NET framework is already installed on that machine, simply skip this step and go on to complete ViSo installation.


  3. The installation of .NET framework fails either with an error code different from '2' or with a message that notifies the user that Windows Installer is missing.
    First, if the operative system is Windows XP, check that the installed Service Pack is at least SP2. If not, the proper Service Pack can be downloaded from Microsoft's website. If Windows Installer is missing, it can be retrieved from within ViSo CD, in a folder named 'Extras'.


  4. The images captured by my wireless camera are not visible or are hardly visible, with strong interference.
    Make sure that your USB wireless receiver is set to the same channel (1,2,3, or 4) of the camera. This information can be read on the stamp placed on the back or on the top of your camera.


  5. Why is my mobile client not able to connect (message 'Network not available')?
    Please check the following conditions in the given order: -phone credit is available on your device; -GPRS/UMTS connection is locally available; -your connection is set to your provider's Web GPRS access point; -proxy server is disabled on your connection settings; -DNS servers are set either to void or to 0.0.0.0 on your connection settings.


  6. When trying to connect, from a mobile client why do I get the message: 'ViSo not connected'?
    Check, if possible, that your Computer running ViSo is actually connected. Check that the 'ViSoID' and 'Password' specified on your mobile device exactly match the ones specified on your ViSo, with no blanks at the beginning. If this problem still occurs: if ViSo was set to 'Permanent Connection', the problem may be due to a temporary lack of network connection, please try again later. If ViSo was set to 'On-demand Connection', please give a call to your phone's number and compose the 4-digit access code you set in connections Options Panel.


  7. Why the Handbook does not open when clicking on '?' option.
    Adobe Acrobat Reader is missing, it can be retrieved from within ViSo CD, in a folder named 'Extras'.


  8. One of my cameras is frozen, after I restart the ViSo, I got error message: "Video Capture Error: value does not fall within the expected range"
    That is because the driver is not installed properly or the driver is conflict with other devices. Please try to install the correct driver or unplug the camera from the USB port and wait for 1 minute to plug it again, if it does not solve the problem, please restart your Computer.


  9. Alarm emails are not received even though 'Email Alarm' option is set to on and one or more alarms are raised by ViSo.
    Please check your email settings on ViSo's Email panel. In particular, all the outgoing mail options should exactly match the corresponding options in your email client's settings. Moreover, check that your recipients' email addresses are existent and correctly written.


  10. Even though 'Sound Alarm' option is set to on and ViSo raises the alarm, no sound is played.
    Your computer's speakers must be turned on. If speakers are embedded in the monitor and monitor is turned off (or it has been switched off by some energy-saving procedure) your speakers will not work. If this is the case, you may disable energy saving procedures or provide external speakers.


  11. I sent the sms to the phone number provided in the instructions but I did not get any sms push message.

    First, it is necessary to activate the email alarm on your ViSo. The email client on your mobile device must be set to the address provided by your phone company.

  22. I installed the application on my mobile phone, but I can not retrieve it to launch it.
    Each phone manufacturer has its own speficic place to store downloaded applications. Nokia uses the main menu (Series 60 2nd Edition), 'Games' or 'Applications' folder (Series 40), or 'My Own" (Series 60 3rd Edition). Motorola uses 'Games' or 'Applications', Samsung 'Applications/Java World'.


  23. Why is not ViSo able to connect on my BlackBerry (message: "Network Not Available")?
    First, check that your BlackBerry is actually on the Internet. If necessary, make sure that the access point (APN) of the GPRS connection is set to the same value (a valid web-GPRS one) both on your device (Menu->Settings->TCP, leave both username and password blank) and on your phone company's data base. If necessary, call your phone company to ask them to check that information.


  24. How do I configure the "email alarm" service?
    Open Options->Email on your ViSo. Outgoing mail settings should match the settings specified for your email client application (e.g. Outlook or Thunderbird). Furthermore, check that all the recipients' addresses are properly typed.

    A sound alarm, conceived to alert your neighbours and/or scare unwelcome guests, and an email alarm, for keeping you in touch with what happens at home.

  28. What kind of Internet connections can ViSo work with?
    ViSo can work with permanent connection (the best solution if you have a flat or cheap ADSL line) or with on-demand connection. The latter exploits a 56K analog modem. On-demand connection can be turned on either by calling your own telephone number and typing the 4-digit code you specified in Options->Internet (only if your modem is voice-enabled) or when an alarm is raised.


  29. Why my mobile device is not able to connect (message: "Verify your ViSo ID and Password")?

    Up to 5.
