Cheap Camera set up for gutter vac

Hi there, 

please can any one give me a link to a half decent camera for a gutter vac. Non recording just for viewing on phone. 
many thanks 

I have an OLFI cam from Grippa it's basically a go pro that you view on your phone.It's ok and does the job but battery seems to not last.

I use a go pro, got it attached to my gutter spike on my pole, linked to my phone 

Just purchased a couple of attachments to speed up using my camera for inspections -

This is will speed up the process of having a look, will just use the clamp to lock onto my Gardiner pole gooseneck.

I have been using the Gardiner camera mount stem but it takes time when you use a hoseless setup having to remove the hose to fit the camera in then having to reinsert the hose/brush ect..
