Windows doesn't detect the camera when you plug it into the USB port?

     When you plug in the camera after installing the drivers and software, Windows will detect and begin to install the drivers for the Web Camera. If you are getting no response from Windows when you plug the camera in, this can be a sign that your USB port is not configured properly, disabled, or has malfunctioned. If your motherboard requires a cable to connect the USB port, make sure that it is plugged in correctly or if you are using a USB 2.0 adapter card, make sure the card has been installed properly.
      If you are unsure of the proper configuration, please contact your system or motherboard manufacturer. If your USB Host Controller is not listed in the Device Manager, enable it in your system BIOS. Try using the camera on another system to verify the camera is working properly.

Why the Digital Video Capture Speed (DVC Speed) cann't mach to the speed described in exposition? Am I use it in the wrong way?

     Many people have a mistake on the question. The main reason is they don't realize the difference between DVC Speed and VCD player's Speed. The difference shows in unit. Supplyers are often describe it by GIF. GIF is the standard resolution, which equal to 352＊288. With in such resolution, a camera can has a DVC Speed at 30 frames per second. Such description as fellow:
QSIF：160×120；
QCIF：176×144；
SIF： 320×240；
VGA： 640×480.
Actually, with QSIF or QCIF, a camera cah reach a DVC Speed at 30fps; SIF, CIF, 20 to 26fps; VGA, 10fps. If your camera's speed even below the above number, you would better complain about it.

What should I know before I install and use my camera?

◆DO NOT put the package plastic bags in reach of children or babies.
*It might cause asphyxia if children or babies putting the bags into their mouths.
◆DO NOT plug the AC adapter into the outlet in improper situation.
*Plucking or plugging AC adapter by wet hand might cause electric shock.
Plugging AC adapter unsteadily might cause fire or electric shock.
◆DO NOT cover the AC adapter when it is connected to power socket, place the adapter near heaters, and put it on the floor which is equipped with a heater.
*The above-mentioned operation might cause fire or incidents.
◆DO NOT use it aboard, please abide by the airway's provision.
*It might influence the communication aboard and the flying apparatus if departing from the airway's regulation. This will result in accident, possible death and severe physical hurt.
◆DO NOT put the camera in the wet place where water might splash or where rainwater and mist might erode(Except weather-proof series).
*This place might cause fire, shock, short circuit, etc.
◆DO NOT disassemble or repair the camera, the receiver and other relevant peripheral equipments.
*Improper disassembly might cause damages to the product or the peripheral equipment.
◆DO NOT put the camera in the quaky places.
*The camera may be unstable or out of operation if installed improperly. Such installation may also cause breakdown.
◆DO NOT use the receiver on the surface of thermolabile material.
*Please embed thermal insulating material when using on the surface of the thermolabile material.
◆DO NOT place or use the AC adapter on temperature sensitive materials.
*The above practice might cause the plastic distortion, fading or sticking on the surface.
◆DO NOT touch, shake or hold the aerial.
*Touching, shaking or holding the aerial might influence the receiving of electromagnetic wave, And thereby influence the receiving effect.
◆DO NOT use several cameras with neighboring frequency working too close at the same time.
*The electromagnetic wave signal of the neighboring frequency might cause slight interferences and so influence the receiving effect.
◆DO NOT let several cameras with same frequency work at the same time.
*The overlap of the electromagnetic wave signal of the same frequency might cause severe interferences and so result in unable to receive signals.
◆Please readjust the button of brightness on TV or on monitor till getting the optimum efficiency.
*There are slight differences of brightness among cameras you can adjust it by the brightness button.
◆DO NOT use the camera in complex environment. The obstruction of stumbling block will affect the electromagnetic wave and influence the receiving range.
*Wall, tree and other stumbling block might absorb, reflect the electromagnetic wave, and influence the receiving range.
◆DO NOT use the camera in the places which are covered by metal.
*The around metal such as elevator, cabin, might shield the electromagnetic wave, and result in unable to receive signals.

◆Enter into "Control Panel", and double hit "Multimedia" icon;

◆Choice "Multimedia", and then choice "Dvice"; Enter into "Video Capture Devices", and bouble hit the name of existing device. A intercommunication box will be opened consequently.

◆Set configuration disable.
