I would like to use propriety components to make a miniature camera that will bluetooth to my Android phone including an led illuminator. Can anyone point me to an engineer who can do this for me?
I hope somebody will come forward to provide you with design and installation services for the whole project. However, it is possible to implement such surveillance projects with a Raspberry PI and a Raspberry Pi camera. You can see an example here: https://www.pcbway.com/project/shareproject/ESP32_Dashcam_w_Night_Vision_2c69ac28.html
You can also use an ESP32-CAM for this project.
