I can get it to work with an ethernet cable but when I disconnect the cable the camera reconnects to wi-fi but shortly after it's gone and the equipment search tool can't find it. I've tried with the DHCP checked and I've tried it without it being checked but either way, it seems to disconnect. My old one worked fine and I may have to dig it out. I'm puzzled.

My 9900 is set to Static IP. Stays connected to WiFi.

I did turn off the 5.8 on my router. Sometimes there can be issues. Not specifically to this camera that I know of, just in general sometimes the 5.8 can interfere.

Other than that, how is the signal strength to the Cam?

Thanks for the input my 5ghz is also turned off. Excellent signal strength. But for a heads up, Foscam tells you this won't work on the 5ghz.

Typically a device that has both Ethernet and WiFi will have two different MAC addresses. Therefore it is important to understand that any IP address reservation on the DHCP server needs to take the different MAC addresses into consideration.

Galfert, this is really crazy. I can't even maintain a wired connection.

Factory reset:

Then try again. Make sure power supply is adequate and well connected.

Mr. Galfert, I have it running only on ethernet and it has been running over an hour. So, since you're the IT Man, what is the best procedure for me to set this up wirelessly? Email me if you'd like.

captgadget · « **Reply #7 on:** January 21, 2021, 06:31:30 PM »

Mr. Galfert, I spoke too soon. It disconnected itself. I don't understand how something hardwired will just drop. And I set up reserved in the router as we discussed before.

Are you running the latest firmware?

FW may be a good call. I never had any issues but as per normal procedure for me it got latest FW as soon as removed from box.

captgadget · « **Reply #10 on:** January 22, 2021, 11:10:08 AM »

FW is up to date. But I'm noticing today by keeping a log it runs about 15 minutes and then disconnects.

What is your router's DHCP lease time?
Have you tried setting a static IP to see if the problem is present then too?

captgadget · « **Reply #12 on:** January 22, 2021, 01:39:51 PM »

I'm giving up! I've asked them if I can return it. I replaced my old camera with this camera which is supposed to the same, at least by model #. The old one ran fine until the other day and all I did when I installed the previous camera was use the Equipment Search tool to find it, Clicked it, opened the camera page, filled in the blanks and galfert helped set up the FTP and that was it. Horrible experience this time.

galfert · « **Reply #13 on:** January 22, 2021, 01:50:21 PM »

Maybe it was a dud. Happens.

captgadget · « **Reply #14 on:** January 22, 2021, 04:47:28 PM »

I may have figured it out galfert. Where I positioned my camera before my power barely reached so I ordered another 10' extension. Now I have the camera in the house and it seems to be running just fine. I guess I will not be able to use that extension cable like I thought I could.

Aha! That goes back to this message:

Make sure power is adequate. A good multimeter is always handy. Glad you got it going.

captgadget · « **Reply #16 on:** January 22, 2021, 05:58:59 PM »

That would be great but you have to know how to use it first.

Got the multimeter out 12.37V at the power supply and 12.37 V at the end of my extension. 12.17 in the house

Well I'm not an electrical expert either, but in this case maybe it isn't the volts the matter but the amps based on distance. How many volts and how many amps are required by the camera?

davidmc36 · « **Reply #19 on:** January 22, 2021, 07:47:07 PM »

Is it measured with camera on? Voltage may drop too low as Gal said if current ability of extension is lacking.

captgadget · « **Reply #20 on:** January 22, 2021, 09:08:29 PM »

Galfert, I'm not that smart. The camera wasn't on it but it's working so I am going to leave the sleeping dog alone. As always thanks for sharing some of your wisdom with all of us here.

galfert · « **Reply #21 on:** January 22, 2021, 09:34:15 PM »

Well I just looked up the product specs from the manual.
https://www.foscam.com/Uploads/usermanual/FI9803P%20FI9900P%20FI9800P%20User%20Manual%20V3.7.5.pdf

Power Supply: 12 Volts / 1 Amp
Power consumption: max 5 watts.

The formula is A * V = W
But we know what the draw is a max of 5 Watts and the Volts is a steady 12 V. Therefore the formula needs to be manipulated to be W / V = A.
This gives us 5 W/ 12 V = 0.4166 Amps.

This means that the power supply needs to put out at least 0.4166 Amps for the camera to work which is why the power supply needs to be rated for more than that which is 1 Amp.

Then to measure what you are getting at the camera you need to use an Amps meter with an induction clamp or put the multimeter in the circuit and and set it for measuring Amps. Then you would know if the camera was or not getting the 0.4166 Amps that it needs. But that is max Amps....which means that probably it only uses that much at night when the IR is turned on. We still don't know what the nominal power consumption is. But we can test the camera without the extension and measure the Amps to the compare to the camera running with the extension to see if there is a difference.

If that is over anyone's head...that is okay. Camera works now so nothing needs to be done. This is just an exercise in case anyone was interested in thinking it through. But again I'm not an electrical expert. Maybe I made a mistake somewhere. If anyone knows any better then please correct me.

Thanks! Good to know stuff like that.

The quick way to see if it is the extension is to temporarily run an extension cord such that you can reach the camera without needing the extension.

That thought did enter my mind but I finally got it working as is so as the old saying goes, let a dead lie and that's what I'm doing. Thanks for your input.
