Digimerge Technologies introduced the 2011 Echelon series of high-performance cameras. The cameras support up to 600 TVL as well as advanced digital noise reduction (DNR), which removes signal noise from night-vision images for clearer night vision and reduced DVR storage requirements. Included in the line-up are bullet cameras as well as weatherproof, vandal-resistant domes with 3-axis brackets for wall or ceiling mounting. Echelon cameras are available with either fixed or 2.8 – 12 mm varifocal lenses, plus infrared LEDs for low-light performance. The products are backed by a full, 3-year warranty, including 1 year over-the-counter replacement.
