Bests & Worsts Reviews from Amazon

***Updated in the comments section 1 year into owning the system*** (K.H.) This is a review of SN500-4CH-002 which is Defender's feature-rich 4 Channel H.264 DVR Security System with Smart Phone Access and 4 Indoor/Outdoor Hi-Res CCD Night Vision Surveillance Cameras. This all-in-one system contains everything you need to setup and record a 4 camera surveillance system in your home or business. For my installation, I did not need to buy anything extra or subscribe to any monthly service to use the system. I can now access the system through any computer in the world as long as it has internet access. I can also access footage by using my smart-phone when I am on the go. I really do recommend the Defender SN500-4CH-002 system for anyone looking for an affordable 4ch DVR security system with web and smartphone access.
