Model: Tapo C500   Tapo C100  
Hardware Version: V1
Firmware Version: 1.3.2

Hey everyone!

 

I am experiencing extremely troublesome problems with both the C100 and C500 cameras. The context is as follows:

  • 20/20 Fibre Internet for the C500 units
  • 500/300 Fibre Internet for the C100 unit (This unit runs inside the business with many others that have similar problems)
  • 2x C500 cameras mounted indoors to the ceiling with WiFi connection (One unit is around 2 meters from the AP (direct line of sight) and the other around 5 (Not direct line of sight); 2.4GHz WiFi)
  • 1x C100 camera mounted near an industrial CO2 laser for us to keep watch of the machine (Around 10 meters from the AP, also 2.4Ghz direct line of sight)

 

The C500 units function perfectly fine for a few minutes (I'm not exactly sure about how long but it's normally less than an hour) before the feed on the Tapo app dies on both. I am able to reboot the one closest to the AP from the app just fine and it suddenly works again for those few minutes before the issue repeats. The unit further away from the AP just fails to connect entirely although the LED indicator on both stay green I believe. A reboot temporarily fixes this but obviously only for one unit and then only for a few minutes. I have even gone as far as to run a static IP on them which do work although it doesn't affect the problem at all for some reason - I think this is important because if I remove the static IP then I cannot see the MAC addresses on my routers portal (DHCP client list, etc).

 

The C100 unit refuses to take a static IP address at all and gets assigned a new IP approximately once a day which is problematic because our NVRs obviously can't connect and thus record from them (I say them because it's a problem with multiple of our C100s!). For some reason, you can't set the static IP on the app like you would for the C500s and if I take the MAC address and add it to our IP Address Reservation list on our routers portal then for some reason this is bypassed (We're reserving 10.0.0.201 for the camera at the machine) and is instead varying between 10.0.0.81, 10.0.0.85, 10.0.0.83. I have triple checked the MAC address from the app but again the routers portal is not able to see this MAC address as connected at all (Both with the reservation and without; this reservation does work as we have many other machines that have IPs reserved).

 

I would appreciate any assistance as the C500 units are used by my family to remotely checkup on my Grandfather that is struggling with his health so it is a little bit important. With that my boss is also getting quite upset about the C100 units that keep changing IP addresses.

Hi, 
1. You can refer to the following instructions to troubleshoot the disconnect issue.
What should I do if my Tapo smart device keeps losing connection or going Offline?
 

Please confirm the following information if the problem remains.
  1) What's the model number of your router and APs? Please describe your network diagram in detail.
  2) Please go to the camera's Device Settings > Device Info page, tap the Wi-Fi icon, and check the RSSI value.
  3) Do you have a Tapo C500 with a disconnect issue and a Tapo C500 display offline all the time on the Tapo app?

 

2. Not all Tapo cameras support the Static IP feature. If you can't find this option on your Tapo app for the Tapo C100, it should be your Tapo C100 does not support this feature now.
If the address reservation entry does not work for the Tapo C100, it's suggested to check your network diagram, and confirm if the Tapo C100 connects to the router directly, or if it's connected to an AP/RE that may virtualize the camera's MAC address and cause the address reservation entry to be ineffective.

 

Best Regards

  @Solla-topee Hi, sorry for the delay, I am so busy with work at the moment that I forgot to checkup on this. I have tried everything mentioned in that basic troubleshooting steps for it but the units are still experiencing the same issues.

 

The information is as follows (C500 cameras):

Router & AP: TP-Link TL-WR841N 300Mbps Wireless N Router

Vumatel Fibre with their unit that has a standard CAT5e cable going into the WAN port of the router (Then obviouslly setup with the PPPoE + Dynamic IP I believe to "authenticate" the fibre).

Cam1 RSSI: "-36(RSSI)" (Both show the signal strength as full)

Cam2 RSSI: "-59(RSSI)"

 

The network here is exceptionally simple; the local IP range is the default 192.168.8.0 - 192.168.8.255 (With the AP on 192.168.8.1). Cam1 (The closer one) has been given a static IP of 192.168.8.200 and the Cam2 has 192.168.8.201. There is likely only around 4 other devices connected to the 2.4Ghz network (I do not have a 5Ghz one enabled at all here) and everything else is pretty much default except for the SSID and password; I have not configured custom DHCP ranges or anything like that and there's no desktops or servers that should be blocking anything here. Both cameras have been given the 8.8.8.8 primary DNS as suggested on a few of the troubleshooting pages although the issue persists on both that and by sending it through the AP like normal.

 

Both C500s had the same problem where opening the live view on the Tapo app would lead to continous loading which then fails and shows a "Tap to refresh" button which just repeats this same problem of loading until it shows the button again.

Hi,
Just double-confirm, whether the two Tapo C500 display the online status on the Tapo app at all times but you can't load the live view page successfully? If so, you can refer to the instructions below to troubleshoot.
What should I do if I can't view the Tapo camera?
 

If the problem remains, please provide the following information.
  1. List the steps you have tried to troubleshoot.
  2. Refer to the instructions below to collect the app log after reproducing the issue, then reply if you have sent us the app log.

Best Regards

  @Solla-topee Hi,

 

Yes that is correct; both cameras appear to connect fine on the app and their status shows connected to the WiFi with good signal; I can even reboot the units through the app which temporarily fixes the problem but then after a few minutes the live view stops working again. I have gone through the troubleshooting steps and can confirm that nothing has fixed this problem (As mentioned before, I did set the primary DNS to be 8.8.8.8 and the link you sent is extremely similar if not the same one that I followed before creating this post).

 

I have tried the following to troubleshoot:

  • Checked the system LED status of the Camera to see if it is connected to the Wi-Fi Network
  • Phone and camera are connected to the same Wi-Fi network (I have tried remote access as well through our business network and then my mobile network as well). The issue persists on the same local network, and remotely both on a business Fibre network and through a mobile carrier (cell data)
  • Tried disabling client isolation, firewall, or access control on the router. There is nothing fancy enabled like isolation, custom DHCP ranges, static IPs (other than trying to set it on the Tapo app for the cameras), virtual networks, or anything like that. The router for the network that the C500s run on are an exceptionally basic unit and cannot really do too much fancy stuff anyways !
  • Tapo app has cellular permission
  • Used public DNS servers (Both Cloudflare's 1.1.1.1 and Google's 8.8.8.8) and private (PiHole and just default router)

 

I will have to climb on a ladder again to see if I can dump the logs to the SD cards and then pull them to provide them over to you should that be necessary
