We have a wireless camera, the update is a little jerky. I prefer the q-see system wired, 8 cameras, one is a ptz, ie you can move it around. The rest are fixed focus. So far it has saved our pond twice while we were gone. I log in to check it out. I had our neighbor come over to search for a leak once, (level dropped by 7 inches) I was able to follow her around the pond with the ptz camera and tell her what to check. She found the leak. It is nice to know all is well at home when you are away, esp with a pond setup. With our underwater camera I can check on the fish too, mainly check water levels, water falls flow, which indicates pumps running, etc. Pond wellness check.
You need to have always on internet, no extra cost to you other than the internet service. I did not need to build a web page, just use the q see system.
The system cost around 300 bucks 1tb harddrive and 8 cameras, cheaper now actually, we have had it for about 3 years.
