Hi All,

 

I have decided to have a small CCTV kind of a setup on my terrace. I have purchased a "Circle GAZE HD-R 1080p" USB2.0 webcam for this along with a USB 2.0 active extension (20 mtrs) to connect it to my laptop. 

 

The Active extension is exactly like this - http://www.amazon.in/gp/product/B00KW68XNS/ref=olp_product_details?ie=UTF8&me=

 

The problem I am facing is, the Webcam gets disconnected quiet often while recording, also at times the systems gives an error as "USB device not recognised/malfunctioned).

 

Can I solve this issue by using a USB 2.0 HUB in between Cam & active extension. Moreover, once I use a USB hub, will it enable me to connect 2 to 3 USB cams.

 

Also, please advise a good video/audio recording application that is freely available online

 

Thanks.

Hello, and Welcome

 

Just a couple of thoughts. First make sure USB selective Suspend is disabled.

 

Even though the USB cable is a repeater, the camera may be drawing too much power from the USB port. Try using a powered USB hub and attach the repeater cable to that. Yes, if the hub can handle the power draw of the cameras you could add additional cameras. Good Luck.

Thanks for the answer.  One additional problem that I am facing is, whenever I turn on any of the Ceiling fans on my floor, change its speed using the fan regulator, the USB Cam connected via the Active cable gets disconnected. I dont know how the active cable is getting interfered by using the switches on my switch board. I tested this by using my laptop in battery mode, still the problem exists. I dont understand the physics behind this. Can any one pls come up with a solution. 

 

Moreover, if I use a USB hub, a normal HUB is sufficient or do I need a externally powered USB hub?

You should use a Powered Hub but in your case that may not work when the ceiling fans are turned on. I would also recommend a UPS. A good UPS can be a livesaver if there is a current surge on the line.  Not sure why it happens with the laptop but maybe it senses a current drop when the fans turn on.

I have tried this with my laptop running on battery(cut off from external power), but still face this issue while using the ceiling fan regulator, sumthing to do with induction,noise & flux that interferes with the active cable. As said earlier, dont understand the physics behind this. Does any one has a solution that will enable me to use this set up without any interruptions.

I am not sure what is happening either. Hopefully somebody else with more electrical experience than me will post a possible solution. The USB repeater cable should be shielded. For a cheap solution you could wrap the cable with Aluminum Foil and then ground the foil but I can say it would work.
