Pros: None. Really, there are no pros to these.

Cons: These are really junk. I have spent hours with tech support but really only about 5 minutes since you cannot get through. The motion does not work, the alarm does not work, you can only constant stream even with their firmware upgrades. Their instructions do not even match the firmware upgrades and the only thing tech support keeps saying is go to this webpage, the same webpage I have been at 100 times. One camera just quit working. It works, then quits, then works, then quits. Everyday the camera's go offline at random times so I have to keep rebooting them. Some days 1 is off some days 2, some days all of them, sometimes they come back on. So I hard wired them to see if the eliminates the issue, nope same problem. The DVR randomly reboots. If you are trying to playback a video stream it just reboots. So your video stremas have all these blank spots. I have spent 40 hours or more messing with these.

Overall Review: We have other video systems. Our home got robbed and we got good videos of the crook so I decided to put in more Camera's so we bought the Zmodo, what a waste of money. We bought these for more security, if they don't work, not much of a security except to hang under the eaves. We have had no issues with the other systems. So now I had to buy another system and install them. Do not buy these.
