Obihai OBI202 VOIP

I bought an Obihai OBI202 VOIP box in November 2013 for my home office; these are $70 from Amazon and elsewhere and often on sale for less (I paid $52.24 shipped).

Obihai OBI202 VoIP Phone Adapter with Router - SIP, T.38 Fax Support

The Obi202 is another great VOIP box, even better than Ooma IMHO, but for more technical users.  For the first year, it provided an absolutely free phone line via Google Voice.  This year (May 2014), Google dropped its support for free outgoing calls, so I signed up for a year of service for $60 with PhonePower.  So far the service has been perfect.

The Obi202 features include:

  • Supports 2 lines
  • Supports multiple VOIP providers (unlike the Ooma Telo which only works with the Ooma service, the Obi202 is not locked to a particular provider and you can configure the box with up to 4 different VOIP providers)
  • Crystal clear phone calls


dd-wrt is open-source linux-based firmware that can replace the stock firmware on many wireless routers and it is awesome.

I use dd-wrt with my dirt cheap ($22) Rosewill RNX-N300RT router and it takes a low-end router and makes it a powerful tool for managing my network.  Some of the key things I like about it include:

  • Separate WiFi guest network that is fully isolated from my home wired and wireless networks
  • Fine control over hours of usage by Wired and Wireless clients (helps limit kids’ access to reasonable hours)
  • Superb web-interface for diagnostics and administration
  • Excellent firewall

dd-wrt maintains a database of routers they support; if you are technically inclined and your router supports it, I highly recommend trying dd-wrt; note that you almost certainly void your router warranty by replacing its firmware.

Foscam IP Camera

In mid-May 2014, I purchased a Foscam FI8910W wireless IP camera to replace my ancient X-10 analog video camera and my experience with it is described below.  Overall, I’m very happy with the camera; it’s a great value.

Foscam FI8910W


  • Excellent feature set: pan/tilt, VGA resolution, awesome IR night vision, 2-way audio, motion detection, automatic uploads/emails, decent mounting bracket, long PS cable, etc.
  • Low cost: I bought it for $55 on eBay from Adorama Camera.
  • Good web interface (excellent in IE, adequate in FF, Chrome)
  • Nice Firefox add-on available
  • Great Android client application
  • The IR night-vision works beautifully; images are clear as day.  This snapshot from my front porch was taken at night; the porch lights are off and it’s pitch black to the naked eye, but clear as day with the IR camera (sans color of course).night_front_side_door
    This one shows the front porch (looking the other way thanks to the camera’s pan/tilt) so you can see how far the IR lighting reaches: you can see the pine tree at the edge of the property…notice how the American flag hanging above the bench has no color in IR.  Again, the front porch is pitch black to the naked eye.


  • Poor security:
    • Access requires unencrypted username/password (http/telnet/ftp)
    • Once logged in, you can ask the camera to display its complete configuration information which sends all users/passwords in plaintext!
  • The web interface is optimized for IE.  The Firefox interface is adequate but a little kludgey (especially the audio).
  • There is a known defect in the DSP image processor in some units that causes the video to drop and the camera reboots when pointed at an image with lots of fine detail.  It took me a while to figure this out; it worked fine until I pointed at my front yard in daytime where the fine grass, leaves, etc. caused constant reboots.  I sent the camera to Foscam for RMA service, they provided a free shipping label by email and within a few days I had a new camera that works perfectly.

Foscam High Gain Antenna

I initially attributed the DSP problem to an inadequate WiFi link because the camera worked beautifully indoors on wired Ethernet or on WiFi.  Foscam makes the camera with a standard SMA connector (I didn’t think this was allowed anymore under FCC regs) and the stock camera comes with a stubby (claimed 3dBi) antenna.  So I bought their add-on 9dBi dipole antenna ($8 on Amazon) that is 12″ long plus another ~2″ for the base!  Naturally it didn’t fix the DSP problem and the stock 3dBi antenna works just fine, giving me a very good signal through several walls.  However, the 9dBi antenna is very nice and well worth $8 if you need more range.

Update 8/24/2014: I just bought another…the best endorsement.
