Yes I understand the No load issue, I’ll try probing the live in after the switch. The 4 pin plug appears to be 2 pairs of 12 v supply, pos and neg, yet only 2 core cable from the PSU is used, so I assume it splits into two in the 4 pin connector? so, to test, could I supply a known good 12v...

No, open circuit, not connected; the led is flashing so I assume voltage should be ok. But tested anyway just in case

Hi, been a while since I needed help, but my trusty Hik DS-7204HGHI-SH NVR suddenly started giving out 3 bleeps every 4 or 5 seconds, this was at 3am so I just powered off. Today I just get the power led flashing every 3 seconds, and no display on tv. I would add that when the bleeding was...

Not exactly sure what brand they are, model is WMDIP24-VCMOS-S if that’s any help. I know they are supposed to have Sony IX323 (?) boards in them.

Hi, when connected to the pc direct, they were powered using a separate power source connected to the 12v power cable included on the camera. Yes the link detect led lights for all 4 on the Poe switch. I know they are receiving power as I can see the infrared leds when dark. Thanks

Hi, Ive now changed the test camera's IP address, subnet & gateway etc via the SADP tool and its now working fine! its still connected to the POE switch and the switch is connected to the router as original set up. I just need to replace all four cams now, which are clearly U/S as they cant be...

ill post images of ip addresses soon. I dont use any ports on the NVR with this set up (see above posts) just the LAN to the router. thanks

Hi Southernyankee, the model of the nvr is DS-7604NI-E1-4P/A ive attached a diagram of current set up - only difference is I only have 4 cams connected obviously. Many thanks

Many thanks for that, just to be clear, I can connect the ‘uplink’ cable from the Poe switch to one of the onboard Poe ports at the rear of the nvr? I will create a diagram of my layout with info; P.s. it’s been running fine for 3 years with the Poe switch connected to the router, does that...

I can’t use the built in Poe ports because I can’t get 4 cables down to the nvr, just the one from the switch. I don’t understand tho that if I do as suggested - plug the Poe switch into the LAN on nvr - how does it send data thru the router? I will try connecting the switch to a Poe port and...

hi, i realise this post is a couple of years old but I have a similar issue where im being advised to connect my poe switch direct to the LAN on the nvr and not the router, but if I do that, how do I connect the nvr to the router for remote access purposes? many thanks for any help

Ok thanks, I’ll try connecting the nvr to the uplink port of the Poe switch, but I still don’t get how remote access can work using hik-connect app etc. The old cams can’t be reset because I can’t detect them whatever method I use. When I search for ‘connecting nvr to cams via a Poe switch’...

Hi, thanks for reply, I tried that with the old cams but no good - haven’t tried with the new cam yet tho. The nvr model is DS-7604NI-E1-4P/A You say never run the cam traffic through the router, but that’s the recommended method when using a Poe switch- according to Hikvision and all other...

Hi, 1, I have to use this configuration as I can’t feed 4 cables to the nvr, it’s been working fine like this for 3 years 2,The nvr & cams can normally be accessed remotely 3, yes tried connecting old cam direct to Poe but no good, however the new cam is perfectly ok if connected to Poe port...

Hi, been running a Hikvision nvr for 3 years, 4 Poe cams connected to a hik Poe switch connected to router, which is connected to nvr. All was ok but it now appears all 4 cams have failed, Sadp tool cannot detect them even when they are connected direct to pc lan. Bought a new hik Poe cam to...
