Hello I'm Italian excuse English but not very practical and I'm using Google Translate. I bought a DVR Avtech CCTV macuser 761 but the seller does not give me support and not even respond to email. As per attached image on any phone (blackbarry, Nokia, Samsung, etc. ..) the last 2 cameras are cut. Also in view of single camera, the problem is. How can I fix? Use EagleEyes version 1.03. Many thanks to those who can help me.
