My home zm installation got hit by lightning and fried all the cams, my bluecherry card and the ethernet port on the mb. Insurance is paying for it but while I was looking for new cams I saw this... http://www.amazon.com/Defender-SN301-8CH-008-Security-Coaching-Surveillance/dp/B003BYRO1K/ref=sr_1_66?ie=UTF8&qid=1339595297&sr=8-66&keywords=security+camera and I wondered how well these things work in comparison to zm. I'm not hung up on that certain item but am curious about that type of device.
