I assure you a hikvision nvr cannot handle the requirements of Monocle without a loopback cable.
I have 4 IP cameras. 3 of them are plugged directly in to the network ports on my nvr. My front door camera is plugged into a separate switch in my living room.
As a test, I removed the loopback cable that runs between my nvr and the switch. I could view my front door camera on my Alexa show using the Monocle Alexa skill.
My Alexa shows would NOT show any of the 3 cameras that are plugged directly into my nvr on my Alexa shows. When I say “Alexa, show driveway” she thinks about it for a few seconds, the screen flashes on and off and then she says “Hmm, the camera isn’t responding”.
The Alexa screen always starts to flash and then you know it isn’t going to connect.
As soon as I plugged the loopback cable back in I could view all of my cameras on my Alexa show.
I feel I have proven this by carrying out all of the necessary steps to show what is and is not possible.
I would be very interested to hear from anyone who has managed to get IP cameras that are plugged directly into an nvr to be viewable on an Alexa show using the monocle Alexa skill without using the separate monocle Gateway. I don’t think it’s possible because of the subnetting that is occurring within the nvr.
I would also just like to thank the guys and girls at Monocle because this is an excellent Alexa skill.
I mafe a post several months ago when I was trying to get the channel zero feed from my NVR to be viewable on my Alexa show so I could view four cameras at the same time.
You may think this is not possible because Monocle is not actually showing the content of the nvr it is showing the feed from each of the individual cameras. However, on the same LAN I can can use VLC Player to view my channel zero feed and it works fine on my laptop. I was therefore curious why the Monocle skill could not show the channel zero.
For those of you who do not know what a channel zero feed is, it is a way of viewing all of your cameras on the same image feed at the same time. This would be fantastic as it means my large 10-inch Alexa in the kitchen would be able to show all of my cameras at the same time which would be really excellent for my home security.
Monocle admin asked me to send them some logs but I made a post a few times to ask how I could send the logs so if anyone from Monocle is reading this please let me know how I can send you my logs to see if we can get the channel zero feed working on an Alexa. This would be a first and another excellent breakthrough for the Monocle team.
