Where to look for a craftsman who can program such a camera?

Question

Do it yourself

Good afternoon!
the project needs a programmer who can program the buttons (add them first) on such a camera.
Examples of what is available:
www.ebay.com/itm/Built-in-battery-micro-mini-spy-H...
https://ru.aliexpress.com/item/Smallest-Portable-1.. www.ebay.com/itm/1080P-spy-hidden-nanny-micro-HD-p
...
www.ebay.com/itm/NEW-Mini-Spy-HD-Micro-pinhole-hid...
to this one (but you will need to add microSD, battery)

There is a button operation module on android, but I understand that such devices ( tiny ) do not install androyd. I could be wrong.
Buttons - give commands to write/delete files.
Which way to look for answers?
Thank you!

Answer 1

Just yesterday I copied and pasted the article: www.konbez.com/single-post/2016/12/29/spyvideo2
In this direction, it’s better not to look for anything at all.

Answer 2

ugly example:
https://codepen.io/nemarta/pen/PjweZg
but here you can see that you can do it without js intervention
why write a script when you can write a couple of style lines (lines 29-32)
I don’t know how correct this is, but I I prefer this way)

Answer 3

Code from the site:

$(".start-page .slider .dir li").mouseover(function() {
            if (!$(this).hasClass("selected")) {
                var m = $(".start-page .slider .dir li");
                m.removeClass("selected");
                $(this).addClass("selected");
                var l = $(".start-page .slider .content li");
                l.removeClass("selected");
                $(l.get(m.index($(this)))).addClass("selected")
            }
        });

But better:

$(".start-page .slider .dir li").on('mouseover touchstart', function(){
    var tab = $(this),
        tabContainer = $(".start-page .slider .content li");
    if (!tab.hasClass("selected")) {
        tab.addClass("selected").siblings().removeClass("selected");
        tabContainer.eq($(this).index()).addClass('selected').siblings().removeClass("selected");
    }
});

In general, by date attributes, I accessed the desired content.
