I shall never trust a company overseas again like GETCAMTRIX. I purchased like others and changed my mind straight away but Paypal who I reported to told me that the shipment was on its way. So I can't trust Paypal now. Anyway the four cameras I did receive but do not work on the Chinese platform of an app. A couple of hundred quid squandered there. That will teach me not to trust adverts. Getcamtrix trade through a dodgy company called Commerce Core UAB in Lithuania. Getcamtrix in the USA and directly import the cameras to you from China. Its a multi-national scam.
