I'm still not clear. LOL
So you did get the 4KBC28?

Re: Very Disappointed by AMC4KBC28 8MP Analog Camera
yes I bought 2. Wanted the 6mm ones but I am happy enough with the 2.8mm ones seeing they have digital zoom options in the OSD. So being able to move it one time forward will work for me needs. Again wish some of the options were in Presets hardcoded in, so someone could use then fast on the fly without having to log into the OSD and make the change. But oh well it is what it is lol.

Re: Very Disappointed by AMC4KBC28 8MP Analog Camera
Gotcha. The power demand issue was raised in several reviews of the BC version with most relating to the IR load and poor night time performance..., along with the Max Power Consumption spec of 6.8W @12V w/IR on. Of course there was also the obvious advice about needing to use higher quality cabling to minimize voltage drop and improve image quality. Both the reviews and the spec are what prompted my 'power hog' comment, not personal experience. As mentioned, I use solid copper 24AWG UTP with most of my analog cameras now. No problems there.
So did yours deliver 4K@15fps on your 7108? And have you experimented with 4K IP cameras on your AMDV8 to see if it recognizes the higher frame rates available with them? As also mentioned, mine ran a Reolink 811A 4K at 25fps. It didn't like it due to the bandwidth load already present (11 other cameras at the same time), but it recognized the capabilities of the camera and still ran it. The main limitation was the DVR's ability to render its own display effectively with the 811A added at that resolution and frame rate. It delivered it to both Blue Iris and VLC fine, though.
I also just checked my DV8 audio options and it seems as though Local and HDCVI are the only selections for all formats.
And you say there's a 6mm version of these available? I've yet to check the digital zoom on mine since it's usually pretty bad in general for any camera. That's the one thing I was hoping to get out of the Reolink 811 -- 5X motorized optical zoom with auto focus. It worked, but too much load on the DVR at 4K and the night vision was just flat out bad anyway. I pulled the plug.

Re: Very Disappointed by AMC4KBC28 8MP Analog Camera
Yes in the 7108 it works at 15fps, In the 8M16-H5 it only does the 7fps.
About 560ma for a 8mp camera with IR seems to me like not something to complain about. Most of that low current is so the camera can work at longer distances.
It is interesting where these cameras were made. Not china as one might expect.
So to change out the Gel pack in these cameras that I do often and no one really should that has a warranty until after the end of said warranty. Remove from base, take out screws on the back and there is a gel back right next to the wires that come into the camera. Wonder if there is a Motorized version of this camera? I say this because there is a connector up by the lens that says Auto Focus on it, It is empty but the connector is there. Don't mean just empty pads it was fitted with a connector that just don't have any wires to it.
About the current, I have a 2mp camera that has 4 leds, 2 close and 2 far as it is a 10x bullet camera, Now It does have a heater, without the heater on it runs in color 200ma to 220ma. With heater on it ran between 320ma to 340ma. Then with IR on in close it was at 800ma and with both ir on at just a little area of the zoom range about 44mm zoom point 940ma, at 45mm zoom with only far oddly it was better at 890ma I guess the far LEDS take less power to run. Now that was after zooming with zoom in action the current was over 1amp. This camera is a Dual Voltage camera and most times I use it on 24vac and that current is different however I don't have a close 24vac at that camera to test it right now But normally they are connected on 24vac because they take less current
So with mine so looking at the numbers today on the other camera to make sure they were both within the same range. Both ran at 200ma and this one says that it is 470ma even with the IR at max level on the IR. I don't remember what it was set at in the start it was like 7 or 8 I think and moved to max value and yet it never went over 470ma once back into color mode it was back to 200ma.
On mine anyway on the second page of the OSD there is a Digital Zoom feature that works well. Kind of what I have come to think about the Amcrest 841, 941 or 1051's however them are using the zoom of the PTZ controls. This is set it and forget it in the OSD and moving the normal 1x to 2 the camera looks good and someone that is adding this camera to a high peak say 30 to 40" of a home don't have to worry about the camera being a 2.8mm because it does offer that Digital zoom that works well. For me it gave it the sense that it was about 5mm and there are 3 and 4 if they wanted to cover a very narrow ROI..
All options in the 7108 for Resolution was offered in the 8M16-H5 besides what the 7108 calls 4k-N for Narrow. That option is offered in my FW of the H5 in my 5mp camera with a 5mp-N and still 7108 didn't in CVI correctly and option wasn't there..
I don't know maybe someone bought a 16ch PDU with only 8amps and so the cameras at max IR for them was over what the PDU offered with all cameras connected. Personally when buying a PDU I would buy one with at least 2 times the power of the PDU size so in a 16ch have 32amps max or better. Or buy a better supply to give the current that is needed for the fleet. Or in my case have more then 1 PDU lol

Re: Very Disappointed by AMC4KBC28 8MP Analog Camera
LOL.. So for kicks I put my camera from the OSD in 6mp format. WOW Don't do that using either of my 2 devices lol. It freaks out the DVR and keeps seeking what type of display it is. I thought for sure I had locked up my camera. However the good news is that just moving the dip switches back to a different mode and then back into the CVI mode it camera back in to CVI at 4k... It don't like 6mp unless I change the camera under 4k mode to 6mp and then I am not sure that it is really 6mp and still works at 7fps.. Even moving the Camera type to CVI didn't help and even moved it to other to see if that would help and it didn't. So I tested 4mp and sure 4mp worked and in the Encoding page it gave me a 4mp-N however making a setting to the N didn't change the display like it does when I connected the 4k on the 7108 in the 4k-N it Slices the picture in half for a narrow view. Crazy that the camera offeres a 6mp option in OSD yet it didn't work in either of the DVRs.
