I prefer stand alone systems that have web capability but do not need it to operate. There are potentially too many security holes in the full on, web operated systems. I like the Zmodo system with 2 TB of storage and 8 +/- cameras. Each camera has a view split into 150 rectangles so you can block out or set the motions sensing sensitivity independently. That is handy. The cameras are hard wired and are powered by 12 v so it is easy to set up a battery backup that guarantees operation even if there is a power outage. The cameras do not have IP addresses and do not transmit over the web so they cannot be easily hacked.
I set up systems to start recording (with a 30 second pre-trigger) only when motion is detected. The 2 TB is enough to record for a couple of months and it writes new info over the old. If there is a problem I can review the record. If not, then i never look at it.
I do not like sending my personal info over the net 24/7. I don’t even want to think about doing that. Sure there is a password that is required to watch the video remotely. But, seriously, does anyone here think China allowed those units to be exported without a backdoor open? I don’t want to make it easy for anyone to watch me or my actions.
