Hey all, I've been researching IP cameras for about a year now. Started with Foscam a few months ago, but soon realized the error of my ways and went with Dahua. Found a great dealer out of New York that gives excellent deals and excellent support. I currently have 4 Dahua HFW3200S's covering the outside and a Dahua NVR3216V w/ 3TB Harddrive for 24/7 recording. I'm waiting for a Dahua K100A to arrive so I'll have 2-way audio at the front door. Using iDMSS Plus App on my iPhone and iPad. The video quality is excellent day or night and I've had no issues with the system.
