Re: Recording Cameras with Pi

Hello,

I do believe Zone Minder may run on raspberry pi. I have used in on a PC and works really good on that though I am not sure if the Pi has enough power to run it decently.

Re: LCD Display problems

Hello,

Thank you for that idea, here is a link of the file https://app.box.com/s/alp7pnm41xav76inayc2 as provided by the company . That is pretty much all they supplied other than instruction on how to wire it up (which was not good).

I had a 14.5Vdc battery and charger from an old cordless drill, I bought a 12Vdc to USB plug and mounted it in a project box and wired that to the battery so I would be able to recharge the battery when needed. Though the battery was very old (about 6 years) I wa...

Re: ST7781R LCD Display Questions

Thank you again,

Yes the driver is installing but I missed copying that part. I think now it has to do with the wiring. I'll keep trying and thank you for all your assistance in this.
