Home made Endoscope for anal view

I have order a USB endoscope by Ebay for try to see inside my anal.

The cam sucks and can not work inside the body.

Any suggestion of a cam that will do the work ?

European websites are recommended for easier shopping.

Hello, what kind of endoscope is it, do you have a link to this product?

Late answer

It was a year ago and I can not find the product but very similar to this one

https://www.amazon.co.uk/Shekar-Inspection-Waterproof-Smartphone-Laptop-3-5m/dp/B01KX0XUXA/ref=sr_1_4?ie=UTF8&qid=1496142884&sr=8-4&keywords=endoscope

The problem migth be that it is very bad to use when it will be close to the wall in the anal.

It can not focus when it is to close inside the body.

I hope some one else have find some USB endoscope that worked better than my ?
