Dropcam Pro

Originally from http://securitycamerawifi.com/top-5-wireless-security-cameras-2017/

This has been praised in reviews as an easy to install monitoring kit for indoor use. It has a great clarity and image quality of 1080p as well as a 130 degree field of view and night vision. Unlike most other brands, it has a zooming feature that allows users to focus on a particular area.

There is no configuration needed for this camera; no memory card changes, no Ethernet cables and no need to set up servers. All surveillance is done in a cloud after installing.

Dropcam Pro

This easy to use system, with all its features can be bought for 150-200$. This is definitely a good bargain for such a versatile and sound home surveillance system.
