Testing Basler's Megapixel Cameras (BIP-1300/1600)By John Honovich, Published on Nov 29, 2009
Basler is a recent entrant into the IP video surveillance megapixel market. Leveraging its extensive expertise in machine vision [link no longer available], Basler's megapixel surveillance cameras [link no longer available] offer CCD imagers, H.264 encoding and a small form factor.
In this test, we examined the Basler BIP-1300 [link no longer available] (1.3MP) and BIP-1600 [link no longer available] (2MP) cameras, testing them in indoor and outdoor scenes under daylight and low light (sub 1 lux) conditions).
Our key findings include:
- Setup was simple and straightforward
- Day time video quality may be adequate but comparatively did not stand out
- Low lux video quality (under 1 lux) displayed details but with some noise and significant motion blur (with camera defaults)
For surveillance, Basler offers a line of box cameras including SD resolution, 1MP, 1.3MP and 2MP. All cameras support MJPEG, MPEG-4 and H.264. Color and Day/Night options are available for each camera. For details, see their product brochure that includes technical specifications [link no longer available].
A few features stand out:
- The cameras are all small. Dimensions are: 89.8 mm x 29 mm x 44 mm (3.5" x 1.2" x 1.7").
- Input/Output on the camera is very limited. Only PoE/network and DC power connectors. There is no microphone or speaker inputs, no dry contacts, no coaxial output, no SD card, etc.
- Frame rate for H.264 is limited to 7fps for the 1.3 MP and 4fps for the 2MP.
- The 1.3 MP camera uses a 1/3’’ Sony EXview HAD progressive scan RGB CCD. The 2 MP camera uses a 1/1.8’’ Sony Wfine progressive scan RGB CCD.
Image/Video Quality Analysis

In various Basler marketing materials, they discuss the benefits of using a CCD imager and the improved performance at low light. We were not able to reproduce the perfectly crisp, high detailed images in those materials. Noise was higher and motion blur was significant at the camera's defaults (exposure at 1 second). With the manufacturer's recommended optimizations (1/8th sec exposure and 18dB gain), blur reduced substantially but the image was darker and noisier.
Setup and Configuration
In the following 2 screencasts, we examine the physical features and the software configuration capabilities of Basler's cameras

Competitive Comparison / Recommendations
The challenge with evaluating Basler's cameras is that the extremely small size is the only clear differentiator we found during testing. Pricing is similar to other megapixel manufacturers. We believe image quality was similar during the day to some cameras but worse than many during low light conditions.
One potential niche is for indoor use where aesthetic concerns and discretion is key. The small form factor of the camera may be attractive.
