I found an action camera that can remote stream to an android device, but then that's 6 cameras x $200, plus the router, and the android device at the TV.
The biggest problem is that the cameras are about 150 feet away from the monitors (so HDMI is out), and it needs to be split to 2 monitors per camera (1 downstairs, 1 upstairs)
What I was wondering is, could I connect a camera to one of these boards and use that as the camera, then connect that board via Cat6 to a board right beside the monitor, then have that one output to the TV via HDMI? Or is there a better solution? These cameras are about 20 feet up, so they'd have to either be constantly on, or automatically turn on when given power and send the video signal automatically. Currently we just have to turn the TV on and we've got video (BNC Camera), and I would like to keep it that simple since some people here aren't as tech savvy.
Why not purchase some cheap android devices [you can even use some old phones] or purchase a few Android P64's.
Use one as your TV display.
Use the others as CCTV cameras, with Cat6 or Wifi.
Install IP Webcam on the cameras.
Install tinyCam Monitor on the TV
tinyCam Monitor can show all cameras at same time or can "slideshow" each cameras in fullscreen.
I use this setup at home [with old android phones]. Very low power consumption too.
Both pieces of software can be configured to run on power on so is tolerant to power outages. Hmmm, tinyCam Monitor definately does. I think the IP Webcam does too. Both have Tasker support on their paid versions.
Suggest you thoroughly test all devices before putting them up high
This why I ordered 3 pieces of Pine64+ w/ 2GB of RAM!
I'm planning to build the exact CCTV system you describe, using USB cameras. My only concern is overheating.
As you probably know already, IP webcam tends to crash if the temperature of the CPU rises.
There are a few questions begging for answers:
Have anyone tried the Pine with IP Webcam and Tinycam Monitor ? If so, does it handle both applications adequately? Have there any unexpected crashes been noticed? What about temperatures while running both apps? These questions are in my head for weeks and weeks now and can't wait to get my hands on the boards and see how they do.
One thing that is also crucial is the fact how good will the video-driver implementation be with Android 5.1.1 and Pine 64 (?) I do hope the guys have done a great job.
If everything goes as planned, this is going to be a fun CCTV project, low-cost and low consumption as well as fully upgradable and futureproof that will be capable of running reliably 24/7.
