Remote surveillance camera based on plain old USB Webcam | DzQ39 |

I recently developed a solution that turns any plain old USB Webcam into a remote surveillance camera. The images taken by the camera can be viewed from anywhere in the world on any device that supports browser and gmail.

The solution is very easy to setup. It doesn't require punching a hole on your router, obtaining dynamic DNS, having a fixed IP address, installing custom-made software on your device, etc. And, aside from your regular internet service charge, there is ZERO operating cost associated with using this solution


How it works

1. Connect your existing USB Webcam to the USB Webcam Controller.

2. Connect the USB Webcam Controller to the Wireless Router at Home / Office / etc.


3. Login to the Web UI of the USB Webcam Controller and enter the account name and password for the free gmail account that you apply for the USB Webcam Controller.

Set the interval at which the USB Webcam takes the photo and send to your gmail account.


4. The images taken are stored in your personal gmail and could be viewed from anywhere in the world on any device that supports browser and e-mail.

5. The possible applications are infinite (pet cam, baby cam, patient cam, security cam, etc.).


Technical Specifications

- Input Voltage: DC 9V (via AC 110V/220V to DC 9V adapter. Can be powered by DC 9V battery in case of power outage);

- USB 2.0 Host x 1 (for connecting to the USB Webcam);

- WiFi: Single input single output (1T1R) Wi-Fi 802.11 b/g/n.

Price & Shipping

- MSRP: US$49.99/ea (including English user's manual and AC 110V/220V to DC 9V adapter);

- Shipping: Shipping cost not included. Can ship via major carriers such as EMS / FedEx / DHL as requested.

- Item Location: Taipei, Taiwan.
