D-Link Wireless IP camera DCS-950G review
The D-Link DCS-950G is a full featured entry level IP
security camera with 802.11g wireless, VGA resolution, sound, motion detection,
email notification, NNTP, ability to record to SMB share and .5 lux low
The camera must be initially set up over a Ethernet
connection with the included software. Once you assign a static ip address
you can use internet explorer to configure and monitor the camera. The
camera downloads an ActiveX control into the browser to view the video and
control the camera. There is a SMA connector on the detachable antenna so
you could use with a external high gain antenna. The camera is powered by
a 5DVC cube so you can use with a DWL-P200 or DWL-P50 power over Ethernet
Image quality is very good video in recorded in MPEG4
format for high quality and small file size.
The camera will connect to any 802.11g or 802.11b access
The main admin page has controls for nightshot low light
mode snapshot and manual recording.
Nightshot works in low light conditions a street or
floodlight will allow you to monitor the area at night.
Motion detection allows you to define trigger zones.
When motion is detected the camera can email you the video
clip via SMTP
The recording menu allows you to upload video directly to
a windows share smart recording works with motion detection.

Long Range Wi-Fi Card ShootoutLong range Wi-Fi Card shootout
We tested the 3 longest range 802.11 wireless
cards on the market today. The Engenius / Senao 2511cd plus ext2
200mW with 2 clip on antennas, Z-com XI-325HP+ 300mW and the SMC2532w-b 200mW.
The measurements were taken outside the building
40 feet from the 200mW Engenius ap pro plus access point through one interior
and one exterior wall.
Engenius card had a 80% signal strength but with
the best in class receive sensitivity of -95dbm it matches the 66% link quality
of the Z-com. The better receive sensitivity gives the Engenius card the
advantage as we move farther from the access point the link quality was
maintained the longest.
The Z-com with 300mW posted the best signal
strength reading of 100%. This card has a maximum receive sensitivity of
:-92 dBm making it less sensitive than the Engenius card. In this short
range test the extra power makes up the difference so it matches the signal
quality of 66%. If we went much farther from the access point the signal
quality dropped off quicker.
The SMC card came in last with a signal strength
of 72%. This card has a receive sensitivity of -94dBm giving it a link
quality of only 26% even with 200mW of power. The connection was still
solid at this level and I was able to access the Internet without problems.
All three cards performed well in this limited
test and they all should be used in different situations. The
Engenius card will
give the best range and speed in most long and short range application.
The Z-com card
would be good for a area with bad multi path interference (metal in walls).
The SMC card
has the best driver and utility for use in a Enterprise environment.
