Review on ZOSI 8CH 1080P PoE Home Security Camera System with 2TB Hard Drive, H.265+ 8-Channel 5MP NVR Recorder, 8pcs 2MP 1080P Outdoor Indoor IP Cameras with 120ft Night Vision and Power Over Ethernet (PoE) by Glenn Cho

So far, this surveillance unit is well ahead of its price tag. This device appears to have high quality hardware combined with modern video technology. Everything you need to install this unit is included. But it has some minor flaws. Good: 1. Great price 2. Modern facilities.3. sensitive motion detection.4. good picture quality day and night.5. Installation was pretty easy and simple. If you can use a screwdriver and safely route low-voltage network cables, then you can install this device. The advantage of POE (Power over Ethernet) is that you only need to run one network cable from the DVR to the camera. This cable carries power to the camera and video data back to the DVR.6. excellent customer service via Facebook Messenger.7. does not require a working internet. Not so good: 1. DVR UI is outdated but works. Further research has shown that most surveillance devices use outdated software for the user interface. I think for ease of use and fewer hardware requirements.2. If you want to view your stored video footage, I strongly recommend connecting a monitor and mouse directly to the DVR.3. Apps for PC, MAC and mobile phones work but need to be updated.4. If you want to monitor the DVR over the Internet, you need a reliable Internet connection. I have a 5 megabit DSL line and my download speeds are very slow, rendering the remote software unusable most of the time. Depending on your tech savvy level, you may find this device difficult to set up, program and view video. I don't think it's limited to any particular company, but to the home video surveillance segment in general. Overall I think this is a good device worth the price.
