 * They were a demo, only worked in low resolution modes, did not preserve the face database between power cycles, and were of little use in real-world applications.
 * There are other (specialised) sketches for the ESP-CAM that do use face recognitioni more effectively, if this is your thing :-)

 A basic limitation of the sketch is that it can can only support one stream at a time. If you try to connect to a cam that is already streaming (or attempting to stream) you will get no response and, eventually, a timeout. The stream itself is a [MJPEG stream](https://en.wikipedia.org/wiki/Motion_JPEG), which relies on the client (the web browser) to hold the connection open and request each new frame in turn via javascript. This can cause errors when browsers run into Javascript or caching problem, fail to request new frames or refuse to close the connection.
 * You can check the `/dump` page of the cam to see if it currently reports the camera as streaming or not.

 To make a permanent config with your home wifi settings, different defaults or a different board; copy (or rename) the file `myconfig.sample.h` in the sketch folder to `myconfig.h` and edit that, all the usable defaults are in that file.
