    New RCA HSDB2A 3MP Doorbell IP Camera

    Hi pete_c, good explanation. That would account for the crash wiping the config despite good WiFi. I do know that each RTSP request launches a separate stream so perhaps if I inadvertently leave my phone app on, and my ONVIF viewer, and my NVR all at the same time that might be a sufficiently...

    Here is Google AI's wisdom on the question "EZVIZ db1 changes back to AP Mode periodically". Not super helpful for me because I have a very strong WiFi connection:

    New RCA HSDB2A 3MP Doorbell IP Camera

    Hi pete_c. That worked! Here is exactly what I did: Reset the DB1 to factory defaults using batch config using Batch Config 3.0.2.6 Changed the SSID, Password, WPA2-PSK, and Working Mode from 'Ad-Hoc' to 'Manage' using Batch Config 3.0.2.6 Rebooted using Batch Config using Batch Config 3.0.2.6...

    New RCA HSDB2A 3MP Doorbell IP Camera

    Hi pete_c. Wow, that is a lot of very helpful info! I have a few questions: 1) I found a post you made describing how to bypass the phone based config app after the DB1 reverts to AP Mode here where you say "You can log in and configure the DB to your liking totally bypassing the smartphone...

    New RCA HSDB2A 3MP Doorbell IP Camera

    Thank-you pete_c. I experienced the same. Settings survive a reboot and even reversion to AD_HOC mode. i.e. today it suddenly switched SSID to sofap_Exxxxxxx and waited for me to go through the config process. 1) Connect to Ad-Hoc SSID softap_Exxxxxx and use batch config to change SSID to...

    New RCA HSDB2A 3MP Doorbell IP Camera

    Hi pete_c. Thank-you for explaining. So I infer from your elaboration that you are managing user additions from the "bottom" section of batch config. For further clarity I enclose photos of my Batch Config Tool showing what my understanding of your explanation is. Clearly, I am a hapless...

    Thanks pete_c. That worked on F/W 211101. Photos attached. By the way, what do you mean by "I do have it registered on the bottom section of batch configuration" ?

    [SOLVED] My Hikvision (EZVIZ) camera cannot detect the SD Card or (possibly) How to unbrick your camera

    You have a Hikvision or EZVIZ camera that does not recognize the SD Card that you just formatted correctly, and inserted into the camera, while the camera was powered off. You have tried all the following: Based on advice from EZVIZ tech support I: 1) Placed a .dav file containing the latest...

    New RCA HSDB2A 3MP Doorbell IP Camera

    Hi pete_c. I used 3.0.2.6 to change DB1 firmware to 200321 (HikVision). I was not able to then create a new user (neither Media nor ADMIN). Screen shots attached. What am I doing wrong?

    Hello David L! Thank-you for your brilliant suggestion. TLDR: The result is "HOW TO INSTALL FIRMWARE ON EZVIZ DB1 (POSSIBLY EVEN IF IT IS BRICKED) USING ONLY THE SD CARD" So I did what you suggested, and got this very nice letter back the next day: Regrettably, the 'issue' that I wrote in to...

    New RCA HSDB2A 3MP Doorbell IP Camera

    Hello pete_c! So you were able to add another user just now to firmware 200321, thus demonstrating this functionality is repeatable on that firmware revision on the EZVIZ DB1 Hardware. Later you will try to add a user on Firmware 211101 on your DB1 but you will have to change firmware on that...

    New RCA HSDB2A 3MP Doorbell IP Camera

    Hello David L. ! I have extracted "Batch Configuration.exe" from your zip file. It is BINARY IDENTICAL to the OEM file by the same name from the 3.0.2.6 install archive. Furthermore, the properties of this file (which are not included in the binary compare) appear to also be identical (and...

    New RCA HSDB2A 3MP Doorbell IP Camera

    Hi pete_c. I have installed Batch Config 3.0.2.3. An interesting discovery ensued: Apparently due to HikVision being lax about updating the file properties when they make a new build, the Windows properties dialog box is NOT a reliable indicator as to what version of Batch Config one might...

    How to install a modern doorbell cam and still have it work with your existing NuTone or similar intercom system

    Many people have covered this topic, but usually for a specific doorbell camera (RING/NEST/EZVIZ/EUFY/Reolink etc) or for a specific intercom system. Regarding the doorbell cam, it probably needs to come with a mechanical chime adaptor known as "The power module" or "The Chime Adaptor"...

    New RCA HSDB2A 3MP Doorbell IP Camera

    Hi pete_c. Thank-you for advising that Batch Config 3.0.2.3 can manage ONVIF activation on EZVIZ DB1 w/HikVision 200321 firmware. Thank-you also for posting the ONVIF tool github code repository. I may need to check both these out further! When I installed HikVision 200321 for DB1 the...

    ONVIF DIAGNOSTIC TOOL

    One of the challenges when configuring an NVR for your cameras is correctly configuring the NVR to get a reliable stable video feed. A second challenge is transporting the alert triggers from the camera's AI detection system, or the PIR events at the camera, to the NVR so that one can choose to...

    New RCA HSDB2A 3MP Doorbell IP Camera

    Thank-you David L. Yes, I tried all the URLs in 101 (and I also composed my own URLs for other EZVIZ products.) I came to the same conclusion, the URL is based on model number and the firmware it downloads changes over time. In both the case of HikVision and EZVIZ DB1 the URL does not...

    New RCA HSDB2A 3MP Doorbell IP Camera

    Hi again peedubya. I had some reflection overnight. Your DB1 repair might be quite simple. Have you checked continuity on the FUSE? (second photo in this post) If yes, and it is good then would you mind taking pictures of the marking codes on the chips identified in these two photos? Also...

    Hi pete_c! Thanks very much for all your contributions to this thread over the years! I did notice that you posted 3.0.2.3 of Batch Config previously here. As you can see from the attachment in my reply to David L I did have 200321_NA_US (Hikvision) loaded on my DB1 at one point. Furthermore...

    New RCA HSDB2A 3MP Doorbell IP Camera

    Hi David, thanks very much for responding! Looks like I am a bit late to the party. I bought EZVIZ DB1 on Amazon in 2021, but I never got around to installing it until earlier this year. Regarding which manufacturers of this hardware are still active, the EZVIZ cloud (Free for "Last 3...

    Upon closer inspection, the spring near TP20 might be the WiFi antenna connection to an antenna on the white case.

    Hi peedubya. I took my DB1 apart today and made some mark-ups for you. I also have a favor to ask. If you still have access to the bottom of the bottom board, would you please post a photo of the SD Card solder connections to the bottom board? (See yellow arrow in my mark-up of your bottom...

    EZVIZ DB1 - Firmware Upgrade

    I need ONVIF on my EZVIZ DB1 so that I can make it work with my AMCREST NVR. The best firmware for that (in my opinion) is the last HikVision release for DB1 Nov 1 2021. More info and the firmware here Also, there is a lot of firmware and tools here . Yay!

    New RCA HSDB2A 3MP Doorbell IP Camera

    In my opinion, the best ONVIF solution for EZVIZ DB1 is to install HIKVISION DS-HD1-2021-11-01.dav You cannot turn off the ding-dong sound at the doorbell itself. You cannot set DST or the Time Zone from the App (it looks like you can but it will not work correctly) You can set the time...

    UPDATE: I am pleased to report that after replacing the device marked AWHM with an MP1567GTF chip (marked AWHN, so 2021 production year) the camera is FULLY OPERATIONAL (unlike Darth Vader's Death Star) I bought the chip here: www.aliexpress.com/item/1005004217646276.html

    Reolink Hardware

    A perfectly reasonable conjecture @VorlonFrog . After all, there is another linear regulator proximate to an SMPS on this PCBA. However, the fingerprint is not a match. SOT23 Linears are typically 3 pin or 5 pin. I had also thought similarly when I cam across them. Incidentally the two...

    I just tore down a Reolink RLC-510WA WiFi CAM since one of the 5 buck switching power supplies on the main PCBA was in need of repair. Yes there are FIVE 5! SMPS on the main PCBA of RLC510WA and two LINEAR regulators. But I digress. Can anyone help me identify the SMPS controller chip in the...
