This Foscam C1 Indoor HD 720p Camera drops from $69.99 to $39.99 with free shipping at NeweggFlash. This is the best price we could find for one by $10. It connects to your WiFi network and lets you remotely stream video to any device over the internet. It also has a passive infrared sensor and a motion detector that can be programmed to send notifications to your smartphone when it detects heat and motion. There is no sales tax (except in CA, NJ, and TN).
