Perimeter Security
Pixim-Powered Cameras Meet the Unique Challenges Posed by Perimeter and Border Applications
Today perimeter security increasingly depends on security cameras operating 24/7. These cameras are designed to keep a constant, vigilant watch over borders and facility perimeters and, most importantly, detect and record when any unauthorized person tries to move from one side of the perimeter to the other side, where he or she is not permitted. Unfortunately, most security cameras don’t perform equally well at all times of the day, under all lighting conditions, or in all temperatures.
Common security camera problems for perimeters include:- Lack of detail of unauthorized people trying to cross a perimeter or border
- Inconsistent clarity in bright or low light, or high-contrast lighting situations
- No image when there's strong glare
- Color inaccuracies in varying lighting conditions
- Poor image stabilization of telephoto lenses
- Low-quality DVR recordings
Pixim’s Digital Pixel System® ultra-wide dynamic range technology, a true breakthrough in imaging technology, delivers unprecedented image quality in all lighting conditions. Cameras powered by Pixim’s specialized image processing chipsets can significantly enhance perimeter and border security through the following capabilities:
- Widest dynamic range: Captures highlight and shadow detail in the same scene.
- Highest total resolution: Makes it easy to distinguish fine image features and details.
- Superior color rendering: Accurately displays color even in difficult lighting such as bright sunlight, glare, and high-contrast lighting.
- No "sun blindness": "Sun blindness" is common in east-facing CCD cameras in the morning and in west-facing CCD cameras in the afternoon.
- No "camera blindness": Eliminates the vertical smear, pixel blooming, and other image artifacts commonly encountered in high-contrast scenes.
- High image compression: Improves image quality with smaller file size - allowing DVRs to record with higher frame rate or higher resolution, or both, while maintaining the same total recording time.
- Less need for DC auto iris: Saves money and greatly improves camera reliability, while also increasing image accuracy for telephoto views.

Pixim, compared with CCD technology, enables the higher compression of images taken by security cameras, which leads to advantages for DVRs:
- Allows the use of higher-resolution settings on the DVR without sacrificing the overall recording time (i.e., # days on a DVR).
- Enables more frames per second to be written on the DVR without sacrificing overall recording time (i.e., # days on a DVR) or resolution.
- Permits the connection of more cameras to each DVR, without sacrificing resolution or frame rate.
- Provides recordings with higher image quality, for more accurate identification of people and events and more compelling evidence.
- Makes it easier to comply with FBI and other regulations that require storage of 10 to 30 days' worth of video - without sacrificing resolution, lowering the frame rate, or reducing the number of cameras connected to each DVR.
- Optimizes the investment in expensive DVRs.

Of the 43 ports of entry along the U.S. border with Mexico, 18 are in Texas – and the Texas border with Mexico stretches more than 1,200 miles. The Texas Border Patrol placed remote video surveillance systems at 29 strategic locations along the Rio Grande, with both day and night cameras that are monitored 24/7 for any illegal activity.

Texas has launched a virtual border patrol with video surveillance.
