I am a private detective. Our company wants to set up a new surveillance van. We need help setting up a fixed IP cellular network and raspberry Pi's to control systems in the van remotely. We have PTZ cameras as well as stationary cameras in addition we have heating and AC, defroster etc that we would like to operate remotely. In some cases we may do surveillance for a week at a time in one location. We don't want to keep someone in the vehicle all that time. We can install as many lithium batteries as necessary. We need to be able to control the environment in the van to protect the equipment. We also want to be able to control the cameras, zoom in and out and occasionally download snippets of video from the hard drive. Would love to here some recommendation on what you all would do and some suggestions on best way to accomplish this. I don't know much about this. I would like some cellular or PC interface that is something multiple unsophisticated investigators could learn to use.
For controlling heating and AC, you could use a Particle Boron and a some relays likethis one:
Have a look at NCD as well:
You could connect one of these boards to a relay board via an I2C bus:
And the I2C relay board, few examples:
Now when you want to control this in an unsophisticated way, you would need to have a website that controls those devices, either custom made or IoT related, example:
If you have more questions, keep asking please.
