Good Quality [Updated after service exchange]

The picture quality is very good, functioning wired (ethernet cable) also. But sensitivity WiFi is disastrous either with or without the external antenna (timeout, packet loss, ...) just 2 meter 802.11n WiFi router! No problems with my other WiFi devices (iPhone, iPad, PC, ...) which are yet more remote router ...
There are 2 revisions of this model: Rev. A / Rev B - I received from Amazon revision A. Maybe this fault has been corrected with the new version.

After an exchange via Amazon.com, WiFi proved very effective! The first impression was not good (the received camera should fail at the WiFi antenna). On the replacement of the camera image quality remained good.
