    New RCA HSDB2A 3MP Doorbell IP Camera

    I just use a 12v AC coil relay DPDT in the circuit. This allows 2 devices to be triggered from the relay contacts. I use 1 for a chime and 1 for an alarm input trigger. It would be nice if someone from Ezviz or hikvision read this forum and could explain how the power kit works exactly. It all...

    New RCA HSDB2A 3MP Doorbell IP Camera

    Been on about about a week now with no phantom chime ringing problems. Obviously the LEDs are on during the night. The DB1C seems to get more false motion alarms compared to the older DB1 with PIR sensor....

    New RCA HSDB2A 3MP Doorbell IP Camera

    Following on from my post here a while ago. I've recently received a replacement for my suspected faulty DB1 doorbell/power kit. The replacement is a DB1C which seems to be working ok so far. Looking inside the power kit, it does seem to be slightly different from the last one, although it does...

    New RCA HSDB2A 3MP Doorbell IP Camera

    Does yours have 4 resistors missing? My suspected faulty power kit only has 3 missing. Can't see any other PCB changes. I was thinking the different codes were just production dates and there might have been a production fault with missing resistors. I'm waiting for replacement so I'll have to...

    New RCA HSDB2A 3MP Doorbell IP Camera

    I would guess 1) faulty power kit or 2) faulty DB1, open up the power kit, does it look like there's any components missing on the PCB. I was chasing a similar problem and after swapping DB1 and power kit between 2 locations the problem also moved. I suspect it was the power kit after opening it...

    New RCA HSDB2A 3MP Doorbell IP Camera

    I have 2 Ezviz DB1 systems using exactly the same 16v transformer and chimes. 1 of them setup over a year ago and works fine. The other setup 6 months ago and the chime will ring at random for no reason, sometimes after several days. I swapped only the doorbell and power kit around and the...

    New RCA HSDB2A 3MP Doorbell IP Camera

    Yes DB1 = 851/MB65 diode rectifier L830CP I think î was the one on the bottom left of pic, black colour about the same size as side rectifier, but only 2 connections. My theory was that the bridge rectifier creates DC from AC to power the IC circuits. I didn't think power kit is used if you have...

    New RCA HSDB2A 3MP Doorbell IP Camera

    That very interesting, but I can't understand why the sine wave is changing. Is your power kit connected correctly - in parallel with your chime solenoid? Or in series ?

    New RCA HSDB2A 3MP Doorbell IP Camera

    Sorry I don't have access to take more pics of the power kit at the moment. But I did take some notes: Components: LM2903 dual differential comparitor LCB710 solid state relay L830CP unknown 851/MB65 diode rectifier 1.5a fuse I think I did eventually wire up an ac relay DPDT so I could also...

    New RCA HSDB2A 3MP Doorbell IP Camera

    Inside the Ezviz DB1 power kit for anyone interested. It's installed across the solenoid wires when using a mechanical chime. For me the chime solenoid buzzed if it's not connected. It seems to allow some of the current to bypass the solenoid to stop it buzzing(and maybe burning out)...

    New RCA HSDB2A 3MP Doorbell IP Camera

    Has anyone with EZVIZ DB1 upgraded to firmware v5.2.4 190708? When I use Hik-Connect and press playback from a PIR notification message, it comes up with "video playback failed. Error code:" I'm sure it worked ok with the previous firmware... It does however work ok with EZVIZ app.. I'm using...

    Strange NVR behavior

    Sorry I was meaning the firmware in the camera, not sure what cameras you have, but if they are EasyIP 3.0 Cameras (G1 Series cameras) then the substream had a problem on firmware before V5.5.82 for me.

    Hikvision NVR slow playback from app and Browser

    Hi All, I've have a Hikvision DS-7716NI-I4/16P NVR with several 4K IP cameras DS-2CD2385FWD-I connected via POE ports. All been working mostly fine, but what I can't understand is that when viewing any of the cameras live main stream via the Hikconnect app or Windows browser, the video lags...
