Trying to identify connector

[SadruddinW]

Hi. I have a wired front door bell/video screen system. Cheap, Chinese, but it works fine.
I've been using just one screen but now need to add another. The system is set up to do this, but I no longer have tge cables to connect the screens and to connect power.
I enclose a photograph of the ones I'm currently using into the back of the first screen.
Looking on line there seem to be lots of different types and sizes.
Could anyone have a look and hive me a clue as to what the connections might be, please?
Thank you in advance.

Measure the pin pitch, then look for JST plug in that range and pin number.
They are available with plug already fitted to multi core lead.

Count the number of pins like the very first one,far left it's called a 2-pin molex connector as American as apple pie.
Now apologize to the Chinese people.
Without cheapo customers like us we wouldn't have all these wonderful crazy electronics. you're going to have to purchase a pin crimper for that particular size if you're lucky you get a kit with an pin extractor as well and get yourself out a ruler and you're going to need the height the width and the length because they come in all sizes and I can't tell from the photo
