Review: EZVIZ DB1C

[bob2701]

What firmware is it using? I had the same problem with 211011 and dropped back to 201106 and solved the problem. But then a few months later it died altogether and I had to replace it. Now running 220802 and no problems.
Good luck.

It's been a few weeks now, and the damned DB1C still loses connectivity at least twice every hour, 24 hours a day. At least three or four e-mail exchanges with EzViz Support, and they are being as ignorant as a pre-historic rock. I finally told them to put up or shut up. Either fix the damned firmware problem, or supply a new unit that works reliably. It's really that simple. One solution or the other, and they can choose. If they continue to play ignorant, I'll badmouth them and plunk them in the same crapper with Reolink, reputation-wise.

I'm just sick of incompetent stupidity.

Ill sell you mine once i get the Reolink POE.

Been working great with ZERO issues.

Woke up about 4 am with the likely answer. There's a wifi config parameter called 'airtime fairness'. Years ago, it caused problems with poorly-coded wifi firmware. Yup, its still there and it was enabled. Just disabled it again and rebooted the router mesh. Let's see if that finally resolves the issue.

Where did you find 'airtime fairness'? AP? BI? DB Config?

Depends on your router manufacturer. On my Asus routers its under Wireless / Professional, along with the low-level wifi parameters.

So I found it on my EAP660, mine was defaulted to OFF...thanks...

 

[VorlonFrog]

This appears to have resolved the issue. In the five hours since i turned off 'airtime fairness', there has not been a single connection failure.
FYI, I informed their customer service team, they should be aware of this feature causing connectivity issues. Many routers default this feature to ENABLED.

Thank you, will add this fix to our 101, assume this would affect the DB1s too...

@VorlonFrog Can I get you to post your fix/discovery in the New RCA HSDB2A 3MP Doorbell IP Camera Thread, thinking this will help others. Thanks...

Great review, goes to show you can get pretty far without dropping hundreds on a video doorbell, and avoid a monthly subscription to prevent it from turning into a brick while you're at it!

FOR SALE

Like New DB1C

Factory reset and ready for new owner.

It looks like after all this time Hikvision is releasing the same/similar doorbell camera (DS-HD2). Hikvision DS-HD2

I'm not having much luck with the DS-HD2. Doesn't seem to support ONVIF. Anyone else tried it? See the new thread here:

Anyone have a Hikvision DS-HD2 on ONVIF or RTSP?

Yeah there is no ONVIF support that we are aware of. RTSP works. Many here use VLC as a good test...which you can find in the 101.

Gonna finally throw this thing in the trash. Constant disconnects the last several months when it worked fine for nearly a year before. Gonna try the Amcrest AD410 and see if it works any bettter.

So I have the ReoLink WiFi Doorbell, don't know much about Amcrest but you may want to check out this DB

New Reolink Wired POE Doorbell Cam ?

Recently found a few release articles and videos by Reolink on their new POE Doorbell Camera. Per comments by Reolink it's ONVIF and RTSP compliant. Although I've been running a YooSee SD-M5 POE doorbell somewhat successfully for several years now I check back here from time to time to see if...

Worth the Watch:


If you can get an ethernet cable to your DB, the POE version would be the way to go.

My DB1C drops out all the time. I've tried many different wifi networks, frequencies, and AP locations. Sometimes it is fine and stable. Sometimes it spends 50% of its time frozen in Blue Iris before the watchdog restarts the stream. I honestly doubt any wifi doorbell would do better.

Luckily the doorbell cam is not very important for me. I have better cameras nearby. It wouldn't even be worth running an ethernet cable up behind the siding at this point for a PoE video doorbell.

I hear ya, in truth no one even presses the doorbell button anymore...I guess the Smart Doorbells are popular because of their convenience of getting notices via an App without having to have a full BI or NVR setup. For us who do, we could do the same with any of our CAMs, maybe not two way audio, but get alerts. I have mine setup through Home Assistant with an automation to send a snapshot of who ever pressed the button or motion setoff the alert in BI, which again I could do minus the doorbell button press. Well I could have a relay capture the button press and send it through a Sage Z-Wave Doorbell sensor. But again Convenience with a SmartDB.

Presently I am running the WiFi version, I have had no dropped signals using RTMP in BI. Though I was one of the lucky ones with my LaView DB1 variant, WiFi worked. Maybe it is my Enterprise Access Points I used. I know 2.4 worked much better than 5.0, my AP is only about 20 feet from the DB.

I know it has to be a pain with all the dropouts. This is why when ReoLink came out with their POE version, that issue is solved for many...just getting a cable ran presents a new issue. I still need to get mine ran.

Try the new reolink

I have had two of the DB1C and I find it to be great using BlueIris (first one died during a bad firmware update - manufacturer eventually replaced it). BI camera status page shows only 7 no signal errors over last 5 days (some of which are power outage related).
My router/wifi-AP is fairly close with a -45dBm signal on 2.4GHz, so maybe that is why my experience is different. You could try using a different SSID for your 2.4GHz and 5GHz and test DB on 2.4 to see if that helps.

So this is BI footage my ReoLink WiFi Doorbell about 30 feet away:



Here is 3 Days of Logs (I am still resetting/testing a lot) No Signal Loss...I have not had One Signal Loss on the WiFi Reolink since I switched to RTMP a few months ago. On my POE Version I am running RTSP...
