1. May I use your product with IP cameras?
IP cameras are supported by NetCamCenter. Click here for more information.

2. Does your software support multiple USB webcams?
Yes. Please see NetCamCenter. However, be aware the quality of USB cameras varies a lot. You should test your setup and make sure the hardware performs as well as you expected. Also USB cameras are limited to 5 M cable length. We recommend using IP camera (network camera) or our video capture card solution instead.

3. I downloaded Webcam Watchdog, Webcam 1-2-3 or WebcamMail. Why it doesn't work with my USB camera?
We try to support as many hardware as possible. However, due to the complexity of PC, it is virtually not possible to support every single piece of hardware in the world. Sometimes the software ask the hardware to do A, the driver or hardware answers OK, and when the software does it, the hardware can't handle it and crash the software or PC. In this type of situation. The software can't predict it will fail in this type of situation.

4. May I use wireless camera with WCSA440e or WCSA440C?
Yes, as long as the camera receiver outputs NTSC/PAL/SECAM signals. However, wireless camera may gets interference easily. We suggest not to use wireless camera if motion detection is on top of your list.

5.Does your software work with my xx USB camera, TV tuner card, video capture card ... ?
We try to make the software work with most of the devices. However, it is a difficult task due to the complexity of video capture hardware and driver. Also video related software are very dependent on the hardware and driver layer. The best way is download a trial version from our web site and test it with your hardware.

6. I download and installed your software but I can't see video on Webcam Watchdog, Webcam 1-2-3 or WebcamMail.
Incompatible video or audio device.

7. What are the differences between WCSA400, WCSP104, WCSA440C and VC400?
Please see product comparison charts and video samples.

8. What are the differences between WCSA440e and VC440e?
WCSA440e = VC440e + NetCamCenter software.

9. What type of cameras can I connect to WCSA100, WCSP100, WCSA400 or VC400?
Any camera with NTSC, PAL, SECAM output can be used with WCSA100, WCSP100, WCSA400 and VC400.

10. I got very fuzzy picture.
Try adjusting the camera's focus first. Also you can try, on Setup/Compression dialog box, adjust to higher compression bit rate. However, most of the time this is because the camera is out of focus or due to poor quality hardware.

11. I want to monitor my 2,000 square feet home. Can you guide me step by step on how to setup DVR systems for local and remote viewing? Or can you install the system for us?

We would love to. But sorry we currently do not have the capacity for this. We are currently a DVR hardware and software manufacture. We currently do not have the capacity to provide installation service. We try to provide you quality products and more DIY information on our web site. And we provide free trial software for you to get start with. It is not an easy job to guide you step by step without being able to see the physical location and knowing your computing environments. This may not be the best analogy. But it is like a manufacture of cookware will try to provide you more recipes, but have no enough chefs to guide you how to cook step by step.

12. The motion detection feature sounds interesting. I want to use this at my driveway.
It is not recommended using motion detection for outdoors or areas that constantly have objects passing by (e.g. convenient stores). The sudden change of sunlight may generate false alarm. Image based motion detection are computed by comparing the differences of image pixels. Computers today are not smart enough to distinguish it is a cat, a leave, a reflection or a shadow moving in front of the camera. Avoid using motion detection around window, with bad cameras or wireless cameras, dark area, or places that the lighting changes constantly. You may get false alarm when using motion detection in these areas. Motion detection helps in certain environment conditions, but it is not a silver bullet.

13. What video format does Webcam Watchdog use to store video? Is it supported by the industry?
Microsoft Windows Media format. The format is supported by leading video software and hardware companies including Microsoft, Adobe, Avid ... etc. The new format is also more robust comparing to the old AVI format.

14. Can I record and playback video at the same time?
Yes, you can record, playback, display and remote viewing the video all at the same time.

15. What is the difference of video resolution?

Please see the sample images below.

320x240
160x120


16. Why is video compression so important?

Without video compression, you can only record several hours for 4 cameras with a 40 GB hard disk. To estimate approximate disk space needed with our products, please click here.

17. What is video frame rate or fps?

It is the number of frames that recorded each second. Please click the video samples below to see the difference.

18. I saw other products also can hold months of video. Does NetCamCenter really do any better on this?

You may want to check out on what conditions it can hold months of video. E.g. frame rate, resolution, video quality and motion detection. Many does so by recording at, say, 1 frame every 5 seconds instead of 10 frames per second, or 160x120 (19200 pixels) resolution instead of 320x240 (76800 pixels) resolution. Some assume you use motion triggered recording or assume objects on the screen does not move or rarely move, which actually may not be able to help in most of the situations. (e.g. stores and restaurants have customers coming in and out all the time) You can view the recording sample of Webcam WatchdogX or NetCamCenter on our web site.

19. Are my videos hosted on your servers?

No. All video are streaming direct from your computer to the visitors.

20. Who are using your remote surveillance related products?

From small convenient stores to Fortune 500 companies, schools, research facilities, home and individual users. They are used in pretty much every industry you can think of.
