Check samples of the Panasonic BB-HCM581 night vision quality . Live video is at TenM3.
With a 0.09 lux rating, the BB-HCM581 can show the scene even in low light conditions as shown at the links above and is used for Video Security applications.

The Camera settings, Scene lighting and upload bandwidth (available to the camera) are all important factors to get smooth video from the Panasonic cameras.
Information on how to improve these factors for smoother video is here
http://www.tenm3.com/forums/viewtopic.php?t=27
In addition, the sensors on the newer cameras (e.g. the BB-HCM581) react to changing scenes faster. This further helps in giving higher frame rates and smoother videos.
When possible, get the newer Panasonic cameras – BB-HCM581, BL-C140, BL-C101 etc.
The Panasonic BL-C and BB-HCM series cameras can be used with the TenM3 Internet service (www.tenm3.com ) - to setup LIVE-feeds and View, Share, Record them.

The Panasonic BB-HCM581, BL-C131 and BL-C1 have different features and prices. Video and Image quality is an important factor while choosing a camera.
The post below shows the Image quality of the BB-HCM581 & BL-C131 and compares the three cameras. The BB-HCM581 has the best video & image quality while BL-C131 is in the middle.
http://www.tenm3.com/blogs/?p=1256
For the best video and image quality, the BB-HCM581 is the right choice – e.g. for broadcasting Events. And if price is the most important consideration then BL-C1 is the right choice – e.g. for home security & monitoring. BL-C131 (and BL-C111) falls in the middle – with a good price and good set of features, it is the choice for mainstream applications.
The other factors that may be important for your application
* Pan-tilt – full (581), partial (131) or fixed (BL-C1)
* optical zoom – 21x (581), don’t care (131, BL-C1)
* night vision – 581 is the best, 131 falls in the middle
* wireless or wired – wireless (131), wired (all)
* sound – 1-way (131, 581), 2-way (581) or don’t care (BL-C1)
A summary of the camera features is here.

A link to the camera prices (on Amazon) is also available at the same page.
Select the camera that best fits your needs for image quality, features and price.
Note: when the newer indoor models BL-C101, BL-C121 are available, they will provide additional feature-price combinations.
Once you have the camera, use it with the TenM3 Internet service. TenM3 makes it easy to View, Record, Share the LIVE-feeds on a large scale. More information about TenM3 is here.

The BL-C131 uses the bandwidth of your Internet connection whenever it is viewed over the Internet.
The Upload bandwidth available to the camera is set from the camera ‘Setup’ page
Login to the camera, then navigate to the page where bandwidth is set
‘Setup > Network (IPv4) > Static’
(the above example is when the camera is used on a IPv4 network with the ‘Static’ settings)
The “max bandwidth usage” parameter is at the bottom of the page.
For the best video quality, the “max bandwidth usage” should be ‘unlimited’. This is also the default Panasonic setting. However, if there are more cameras on the network, or bandwidth is needed for other uses, then the ‘max bandwidth usage’ should be changed to a lower value.
Try different settings for “max bandwidth” to see how it affects the video quality. Usually, a minimum of 0.2 Mbps is required for the camera.
With the TenM3 Internet service (www.tenm3.com ) and Panasonic IP cameras, you can setup always-on LIVE-feeds from anywhere and View, Share, Record them at Internet scale.

The video quality from a network camera (e.g. the Panasonic BL-C131) depends upon the bandwidth available between the Camera and the Viewer. Higher bandwidth will deliver better video quality. Any factor that reduces this bandwidth reduces the video quality. The two main factors affecting the bandwidth and how to improve them are given below -
1. Camera-Viewer network – Most often, the network cameras are viewed from the Internet. In this case, make sure the highest bandwidth connection (that is possible and affordable) to the Internet is in place for the camera (check with your ISP on type of connections & pricing available for your location). For viewing network cameras, the upload (to the Internet) bandwidth is more important than download bandwidth.
Network cameras require at least 200 kbps of bandwidth to View the video (and the higher the bandwidth, the better the quality). Most broadband connections easily provide this. However, some basic DSL plans cannot guarantee a minimum bandwidth. Their bandwidth can fluctuate from 10 kbps to 400 kbps depending upon the time of the day (and the number of Users on the ISP’s network). Such plans will give no video or very poor quality and should not be used.
If the network camera is viewed on the local network (LAN), make sure that the highest bandwidth connection is available between the camera and the viewer e.g. 10 Mbps, 100 Mbps or 1 Gbps and no switches or routers in the path reduce the bandwidth.
2. Sharing the camera and Number of Viewers – For best video quality, there should only be a single connection to the camera.
If you Share your camera views with others and the others are directly accessing the camera, then more the Viewers, the worse the quality. E.g. for a camera on a typical 400 kbps (upload) Internet connection – 1 Viewer will get the full 400 kbps bandwidth. 2 Viewers will get ~200 kbps each, 3 Viewers will get ~133 kbps each, 100 Viewers will get 4 kbps each. With each new Viewer, the video quality degrades significantly. Multiple viewers going directly to the camera should not be allowed.
To avoid such a situation, when you want to Share your camera view (and a lot of us want to do that), the camera-view can be registered with the TenM3 service. The TenM3 service makes a single connection to the Camera. The TenM3 feed can then be shared with a very large number of people.
If the Camera is on the Internet, access to the camera should be password protected. If the camera is open, anyone from the Internet can access the camera potentially seeing a private feed and also increasing the load on the camera. Use of TenM3 helps here also, as direct camera access is never given to others while sharing the Feed and the camera can be protected.
Overall, to keep the video quality of your camera good and consistent
- get the highest bandwidth connection to the Internet (that is available and affordable) and
- use the TenM3 service to View, Share or Record the feed
