1Warning
1.1. Battery Caution
Danger of explosion if the battery is replaced incorrectly. Replace only with the same or equivalent type recommended by the
manufacturer. Discard used batteries according to following caution:
Disposal or transportation of lithium batteries should be performed by permitted, in accordance with federal, state and local
guidelines.
A battery continues to have no transportation limitations as long as it is separated to prevent short circuits and packed in strong
packaging.
Commercial firms that dispose of any quantity of lithium cells should have a mechanism in place to account for their ultimate dis-
position. This is a good practice for all types of commercial or industrial waste.
When the lithium battery is exchanged, the clock settings are cleared. In this case, make clock settings again.
Recommend Type Number:
N4BCY48Y0001(CR2032NT23) (BT901) Manufactured by HITACHI MAXELL
CR Coin Cell Lithium Battery Information:
This product contains a CR Coin Cell Lithium Battery which contains Perchlorate Material-special handling may apply.
See www.dtsc.ca.gov/hazardouswaste/perchlorate
1.2. About Lead Free Solder (PbF: Pb free)
Note:
In the information below, Pb, the symbol for lead in the periodic table of elements, will refer to standard solder or solder that con-
tains lead.
We will use PbF solder when discussing the lead free solder used in our manufacturing process which is made from Tin, (Sn),
Silver, (Ag), and Copper, (Cu).
This model, and others like it, manufactured using lead free solder will have PbF stamped on the PCB. For service and repair
work we suggest using the same type of solder.
Caution
• PbF solder has a melting point that is 50°F ~ 70°F (30°C ~ 40°C) higher than Pb solder. Please use a soldering iron with tem-
perature control and adjust it to 700°F ± 20°F (370°C ± 10°C).
• Exercise care while using higher temperature soldering irons.:
Do not heat the PCB for too long time in order to prevent solder splash or damage to the PCB.
• PbF solder will tend to splash if it is heated much higher than its melting point, approximately 1100°F, (60 0°C).
• When applying PbF solder to double layered boards, please check the component side for excess which may flow onto the
opposite side (See figure, below).

BL-C230A
1.2.1. Suggested PbF Solder
There are several types of PbF solder available commercially. While this product is manufactured using Tin, Silver, and Copper,
(Sn+Ag+Cu), you can also use Tin and Copper, (Sn+Cu), or Tin, Zinc, and Bismuth, (Sn+Zn+Bi). Please check the manufac-
turer’s specific instructions for the melting points of their products and any precautions for using their product with other materi-
als. The following lead free (PbF) solder wire gauge are recommended for service of this product: 0.3mm, 0.6mm and 1.0mm.

1.3. For Service Technicians
Repair service shall be provided in accordance with repair technology information such as service manual so as to pre-
vent fires, injury or electric shock, which can be caused by improper repair work.
1. When repair services are provided, neither the products nor their parts or members shall be remodeled.
2. If a lead wire assembly is supplied as a repair part, the lead wire assembly shall be replaced.
3. FASTON terminals shall be plugged straight in and unplugged straight out.
ICs and LSIs are vulnerable to static electricity.
When replacing, the following precautions will help to prevent recurring malfunctions.
1. Cover the plastic parts with aluminum foil.
2. Ground the soldering irons.
3. Use a conductive mat on the work-table.
4. Do not grasp IC or LSI pins with bare fingers.

3Features
On-site and remote camera monitoring
Camera images can be monitored from a PC, both on-site and over the Internet. You can even use your mobile phone to view
still images when you’re out of the house.
H.264, MPEG-4 and Motion JPEG (MJPEG) support
Live camera images can be viewed and buffered (i.e., stored in memory) in H.264, MPEG-4 and JPEG (MJPEG) formats, allow-
ing you to select the video format that best suits your needs.
Built-in sensor (human detection sensor)
The camera features a built-in pyroelectric infrared sensor, which uses infrared rays to detect temperature differences within its
range that are emitted naturally by people, animals, etc. The sensor can be used to trigger the camera to buffer (i.e., temporarily
store) camera images in its memory. You can view these images later as desired. The sensor can also be used to trigger the
camera to transfer images to someone or somewhere, by FTP, E-mail, or HTTP.
Backlight Correction features
When this feature is enabled, the camera can automatically correct the contrast in dark areas of the camera image. This means
even when there is backlight or a large amount of contrast in the image, the camera can correct the image to provide a more
consistent, natural image.
Audio features
The camera features a built-in microphone that allows you to monitor the audio while viewing live camera images using your PC.
Detection feature
The camera’s motion or sound detection feature allows you to buffer or transfer camera images when the camera detects
motion or sound in the camera image.
Camera image buffering and playback
Camera images can be automatically buffered at specific times, when the camera’s external sensors (customer-provided) are
triggered, or when the camera detects motion. You can program the camera to buffer these camera images, and then you can
play back these images later while accessing the camera or save them to your PC. You can also program the camera to transfer
images by E-mail or upload them to an FTP or HTTP server as they are being buffered.
Digital zoom
When viewing camera images from a PC, you can zoom up to 3×(by length) and get a closer look. You can use your mouse to
zoom in and out simply.
Protecting your privacy
Simply press the camera’s PRIVACY button to hide the lens from view and protect your privacy. You can even activate the pri-
vacy mode while away from home.
UPnPTM support
When connecting the camera to a UPnPTM compatible router, the camera’s network settings can be automatically configured,
making setup quick and easy.
Viewnetcam.com support
After registering your camera with the Viewnetcam.com service, you can access the camera while away from home using an
easy to remember Internet address of your choosing, such as ***.viewnetcam.com.
Multi-language support
All camera pages can be displayed in English, French, German, Italian, Spanish, Russian, Simplified Chinese, and Japanese.
The most commonly used camera pages can be displayed in Korean.
Wireless connectivity
The BL-C230 supports wireless standards IEEE 802.11b and IEEE 802.11g, giving you the option of using the camera in either
wired or wireless mode. When used in wireless mode, WEP, WPA-PSK(TKIP), and WPA2-PSK(AES) support ensures that
access to the camera is secure.

Analog/RF Section
• a) Transmit
Transceiver IC receives in-phase and quad-phase signal from MAC/BB IC. Frequency is changed by two steps of mixers inside
IC. The 1st mixer outputs 1.6GHz. The 2nd mixer outputs 2.4GHz. The 2.4GHz transmit signal is amplified with a power ampli-
fier.The power amplifier drives a coupler/detector assembly. The Coupler /detector’s function is to sample the transmit signal and
rectify it. The rectified signal is proportional to the output power and is used for power leveling and control.
The RF transmit signal then passes through a dual band switch. This switch enables the connection of the input to external
antenna.
• b) Receive
The 2.4GHz receive signal is transferred in a reverse order from the antenna through the switch. It is amplified by a low noise
amplifier and fed back into MAC/BB IC.
Frequency is changed by two steps of mixers inside IC. The 1st mixer outputs 1.6GHz. The 2nd mixer outputs base-band signal.

System Requirements
Your PC and network must meet the following technical specifications in order for the camera to function properly.
*1) What is IPv6?
・IPv6 is short for “Internet Protocol Version 6”.
･IPv6 was created to provide the additional IP addresses that will be needed as the Internet continues to expand.
･IPv6 is expected to gradually replace IPv4, with the 2 coexisting for a number of years during a transition period.
･Though most ISPs (Internet Service Providers) do not yet support IPv6, many local networks already use it. When your ISP
supports IPv6, your Panasonic Network Camera will be ready!
･For more information, visit http://www.ipv6.org/.
