Advice is needed on Cisco WVC210 PTZ WiFi camera (autonomous power supply)

Alex-VII

I plan to use my new "Cisco WVC210 PTZ WiFi web camera" on wheeled robots. The camera power supply adapter has an output of 5 V DC, 2 A.

I've measured the adapter output voltage with a digital voltmeter. It is 5.39 V. I measured the voltage several times. It is always 5.39 V.

Can I use 4 "D" 1.5 V batteries as a power supply for this camera? The output will be 6 - 5.9 V.

In the specification of the camera is written:

"Power: 5V DC 2.0A switching power supply"

I've asked at the Cisco support forum but got no reply yet. Probably they have not much experience with robotics yet.

I am not sure if I shall build a DC-DC converter or should just try to use the camera with 4 "D" batteries with output of 6 V. Or will I burn the camera with 6 V instead of 5.39 V?

I would guess that it would be okay with 6 volts, but I don't know. You could put a single rectifier diode in series with the power supply, that would lower the voltage by about .7 volts. Make sure the diode you select can handle the current.

You could also·take the·7805 voltage regulator and·a 2N3055·power transistor, in the·emitter follower·configuration:

Connect the 7805 output to the·base of 2N3055, and·12V to the·collector of 2N3055, you have the

output of 5V with high current from emitter of 2N3055 power transistor and·remember the heatsink too.
