Wyzecam power supply failure

support

#1

I know this may not be the greatest way to post this, but I figured I’d try anyway. I have a Wyzecam V2 and it was recording badly to the SD card. Video was choppy and it clicked constantly. Then the power supply failed and I replaced it with a new one rated at 2 amps. Suddenly it’s working perfectly. Is it possible that there are some borderline power supply’s out there that are causing that type of problem for a certain percentage of people?

It’s pretty cheap to just buy one and most people have them laying around anyway.

Makes sense. Also reminds me to ask when people are having trouble, are they using a cheap long cable. Long cables with thin wires will cause big voltage drop which will cause issues.

It’s still working. No more annoying clicking either. I’m starting to feel confident that this is a problem. People need to swap out the usb power supply at some point if they’re having problems, as it may just solve them.

I started having choppy video issue, when I moved my v2 outdoor and started using existing camera system cables as power cable for my v2. Existing cable about 50 feet long and good thick cable. With these long cable, I am using 5v 2amps power supply.

To resolve this choppy video issue, should I try with increasing more amps power supply? Like 5v 3amps power supply? What’s your suggestion?

The thickness of the cable doesn’t matter, nor does the amperage of the power supply as long as it is sufficient. What matters is the gauge of the wire within the cables. To narrow and you will get too much voltage drop. Here’s a voltage drop calculator:

However, I think it’s probably more likely that being that far outdoors, you are getting a weak wifi signal that is causing the video issues.

It is better to increase the length of the AC power cable, rather than increase the length of the USB power cable. The reason for this is AC has a lower drop over distance than does DC voltage and current. Also lower voltage is more prone to drop than higher voltage, 5 volts DC vs. 120 volts AC. That is the reason Edison lost and Tesla won in the battle for AC or DC power back in the day. Use a high quality outdoor extension cord rather than a cheap USB extension cable to extend power to camera’s power ports.

Hope this helps,
