Eufy E340 Floodlight Issues

On the 1st day of fitting the cam everything worked fine however on the 2nd day I notice issues in the eufy security app when viewing live such as lag, buffering, failed to play live-retry, this happens when I move the camera to the right via pan & tilt controls or selecting a preset that involves moving the camera to the right. And the audio in the live is intermittent too, sometimes I hear and sometimes I don’t silent. When I touch Retry on screen the live loads again fine but still above issues persist.

What is causing this? For moving the cam up, down, left it works fine but why the lag, failed connection, live failed black screens, intermittent no audio when moving the cam to the right?

The connection test result in the app reports back as ‘Great’.

Cam have latest firmware and Eufy security app is latest version.

The cam floodlight is connected to Wi-Fi 6 router because I do not have homebase and I bought good 128gb micro sd cards. I bought the floodlight cams brand new from Costco UK.

I even tried restarting the device but issue still persists.

Please help.

Restart the phone. Reinstall the app and reinstall. If neither works, it could be a fauly camera. Contact Eufy support

The electrician fitted the cam high up on the wall that I cant reach. When you say faulty Cam will Eufy reimburse me the electrician installation costs and also the costs of getting another electrician to disconnect the cam if Eufy wants me to return the cam back to them?

What is the camera using for its Wi-Fi connection?
2.4 GHz or the 5 GHz.

It still may be a week Wi-Fi signal that’s causing the issue, even though it’s telling you it’s great at the moment.
If you have it connected to the 5 GHz Wi-Fi change it to the 2.4 GHz as that band has better distance range.

No. eufy will not pay for installation or removal costs reimbursements.
Did the electrician wire the flood light up to a wall switch? So you can power cycle it off and then on.

That happens to me to from time to time

Restart

Yes wired it to the wall switch. Will switching it and off and on like this cause any corruption to the software or firmware of the cam or cause any corruption to the memory card in it? Similar to switching off a PC at the mains instead of clicking on Shut Down and once rebooted it triggers Safe Mode possible damage?

Yes how do I change the band to 2.4 Ghz?

Do you think the cam cache gets full after a day causing it to be sluggish and slow?

Ahahahah :joy:

I don’t have that camera, but it shouldn’t cause any issues turning it off waiting 5 minutes and turning it back on.
I have other eufy wired cameras and I’ve done this before with no problems.

In the camera settings page scroll to the bottom to see if you have an option to Restart Device, if available tap on that.

Not sure how change it to 2.4 GHz for your camera. Look in the General settings for Wi-Fi connection.

Hi yes went into general settings and found wi-fi menu and cant find the setting to use 2.4Ghz band. Is it advertised on the camera light box that is wi-fi 6 dual band 5Ghz and 2.4Ghz and my TP-Link Archer AX20 v2 Router is wi-fi 6 and also dual band.

Please advise.

I’m sorry I can’t help you any further, as I don’t have that specific camera model.
Hopefully someone with that camera will post here and try to assist.

In the meantime, you could contact eufy support and tell them what is occurring with your flood light.

It would be the distance the camera is relative to the Homebase or router is to far apart, so the signal is weak.

Okay you happen to know any settings in my wi-fi router I can optimise.

The dual bands 2.4Ghz & 5Ghz are smartly combined in my router. Shall I disable this setting?

Newbie question, does the camera still record to its local micro sd card if it loses wi-fi connection to the router and recordings can be accessed days later via the phone app when wi-fi at home is available again?

Yes, it will still record to the SD card if the camera loses its Wi-Fi connection, as long as it still has electrical power.

Wow

Another Newbie question I have is if the Wi-Fi SSID network name changes or wi-fi password changes or I buy a new router then do I still require the QR code from the cam packaging box to connect to the new SSID network or router or I have to get a electrician to get the cam off the wall and go through the same initial setup process again like out of the box new and connect to new wi-fi again?

I’m asking because I threw the box away.

If you change the SSID network name or password then you will need to be able to reach the camera and press the Sync button to change the network info and password on the app for that camera.


The QR code is only needed when you’re doing an initial setup, for adding the device to the app. There is also a QR code located on the camera itself.

If you are getting a new router / Wi-Fi, then just change the new SSID network name and password so it’s the same as your old router / Wi-Fi.
Then you won’t have to change any other devices Wi-Fi settings because you’re using the same SSID and password.

What it is by default My router has combined 2.4 GHz and 5 Ghz into 1 network SSID name.

If I disable this feature in my router settings and separate 2.4 Ghz and 5 Ghz into 2 SSID separate network names then do I have to still go up high to reach the cam physically? It is installed high up on my house that I cannot reach. The electrician used a tall ladder to get up there.

If I separate the 2.4 GHz and 5 GHz then will my cam connect to the 2.4 Ghz without requiring me to go up to the cam physically using the same wi-fi password?

To confirm if I remove device from app then I need the QR code?

What is your advice please?
