I have been looking at ways to stream video from my bike to my phone and to have the phone as the only way to arm/disarm alarm systems. My 1st idea is to use esp8266basic or esp8266Python. A web page menu system that only responds a username, password and the mac from my phone. With the esp8266 can one do digitized audio/picture/video ? 2nd is A cheap netgear wifi router running on 5v to 12v I could use a something like one of the many cameras like "the ring doorbell camera". And here is the bad part with many of these devices. Your not talking directly to it when setting them up. Your going through an app on the phone. I was sent one of these with a 2 relay module order. They didn't want it back. So I looked it up and found an app for the phone.  This one wanted my wifi SSID the newtwork password. I may be wrong but it seemed to me this information was going out the app and over the internet before reaching the device. Now if it was to the device only that would be fine. This now has me wondering how many of these IOT devices are getting people to hand over the keys to their home network. I have setup many of the older camera systems. Where your putting the information directly into the DVR. Much like setting up a router/computer information stays inside the network. Any thoughts |

i've struck something similar with google chromecasts. the first time i set up a chromecast, i plugged it into the TV and on the TV screen appeared a message telling me to connect to ssid <something> to complete configuration. upon connecting to that ssid i was prompted to enter my wireless network's name and password, after which the chromecast reset itself and thereafter appeared on my notmal network. all very simple, no software download was needed. the NEXT time i went to set up a chromecast, when plugged into the TV the message on the screen instructed me to download some application from google that would collect my network name and password. no matter what i did, i could not manage to get the blasted thing running without installing google's application. as i recall, i was able to find the requisite ssid, but when i connected to it i just got a blank webpage - nowhere to enter a wireless network name and password. it does seem that everyone now wants to force you to install their application on your phone/tablet/computer. it is all good reason to opt-out of this whole IoT thing. cheers, rob :-) |

Yes, don't like the sharing of my private info with cloud/web app. How about this with raspberry pi: https://randomnerdtutorials.com/cctv-raspberry-pi-based-system-storage-motioneyeos/ I found it easy to set up. On a bike, r-pi might require too much power, so what about ESP32? https://www.youtube.com/watch?v=S2yTQHM82jc&feature=youtu.be https://www.youtube.com/watch?v=DlyGBCnC_4Y https://github.com/mic159/ESP32CameraI2S PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on fruitoftheshed |

The SSID and password SHOULD only be for the LAN connection and your WiFi, so that it can establish a connection to the net via your gateway. Every iPhone, iPad, Samsung pad, laptop and Smart TV in the world do exactly the same thing when you set up their wireless connection. It's when those intermediate apps are in the mix, that you need to be concerned as you have been, cos no-one really knows what they are doing with that data, and every flippin' app is different.  Basic rule of thumb: If any device wants to use an intermediate app on a phone or tablet to set it up, use something else if you are at all concerned about your network security. Smoke makes things work. When the smoke gets out, it stops! |

lizby Thanks for the links. I have a few of the RPi Zero W's to try a variation of that as I do want MMBasic. I only need one camera. The RPi W will out put a composite in color I think. Right now I am using a DuinoMiteMini (B&W) with the composite video out feeding one of the inputs to a 5" car backup display. The other is the camera that came with it. I can see whats behind me. When I push a button I get the bikes status Speed/Voltage/TimeLeftToRide for about 20 seconds. I have been trying to get the serial port data of the controller. It's 9600 baud but the information I need is what I send to it to turn on pas and a few other features. Also it can give me the Voltage/Current and I think speed. The battery I have is 48V 20AH Lifepo4 Rechargeable Battery Pack with BMS.  I am using two down converters one for 12volts the other 5volts. Needed these they take up to 60Volts input. Fully charged battery is 58.4Volts.  |
