PTZ presets: wireless or cell or mechanical button

[bug99]

Is there a decent way to use a remote of some sort to go between 2 or three presets on a Dahua camera? I am up for trying almost anything, so long as the end result is fairly clean and robust. Thoughts are programmable RF remote to a IP gateway, cell phone app, wall buttons with or without raspberry Pi. My thought is to try it with the new SD1A203T-GN or the DH-SD12203T-GN, but the technique should likely apply to many models.

I would love to hear some creative ideas.

If you have time to put into custom programming, you can use a wireless numpad as a cheap type of button pad. I have put together 5 of these in my house, which I use for home automation.

The tough part is finding software to respond to the key presses. I had to write that myself.

An easier solution, although one that doesn't last 6+ months on a single AAA battery, would be an android phone or tablet running an app like HTTP Request Shortcuts - Android Apps on Google Play and maybe with another app to keep the screen on 24/7.

How would the HTTP shortcut method command a preset position? Is that something that can be passed in the URL like the login and stream and substream data choice?

You can use software on a PC like auto hotkey to trigger commands that would change the preset (using http api for camera). There are lots of ways to do it with something like an ESP8266 or Pi zero w
