Honeywell's line of infrared-illuminated cameras uses the latest True/Day Night surveillance
imaging technology to deliver brilliant color images during the day and improved low-light
sensitivity at night. IR technology automatically adjusts intensity to avoid hot spots in the
image to deliver extremely clear, sharp images regardless of lighting conditions.
The HD4DIRS combines Digital Noise Reduction (DNR) technology with 18 integrated
light-emitting diodes (LEDs) to improve overall image clarity and compression efficiencies
on DVRs. By removing noise artifacts such as electronic static, DNR technology optimizes
motion detection performance by the DVR. When used in conjunction with the HD4DIRS
photo cell-driven IR LEDs, using a dual window IR cut and IR pass filter, DNR captures a
crisp, clean image, enhancing the integrity of the recorded video.
Generating 600 TV lines of resolution, the HD4DIRS produces sharper images down to
the smallest detail with outstanding accuracy. A 3.3-12 mm IR corrected Varifocal Auto
Iris lens eliminates focus shift when the camera switches between color and IR modes.
In addition, an optical lens shield located inside the dome delivers evenly distributed
nighttime vision with no internal reflection or “halo” effects.
The HD4DIRS is designed for simple installation and use in the most challenging
environments. The ultra-rugged die cast aluminum housing and scratch-resistant
3.5 mm-thick polycarbonate dome cover is IP66-rated for outdoor installations and can
withstand heavy external impacts, making it ideal for installations where structural integrity
and vandal resistance are important.
The HD4DIRS housing can instantly convert from flush to surface mount on a wall or
ceiling or directly to a 4S electrical box. Setup is quick and easy and can be customized
on-site using the provided second video service cable and user-friendly on-screen display.
The housing also includes both composite and unshielded twisted pair (UTP) outputs.
In addition, the housing incorporates a heater that allows the camera to work in
temperatures as low as -40ºF (-40°C) and a breather vent that prevents condensation from
forming inside the housing. Optional wall and pendant mount kits are available.
The HD4DIRS is a true 24/7 surveillance solution designed for object recognition in
locations where little to no light exists. The compact, one-piece design allows for fast,
easy installation in nighttime surveillance. It is ideal in commercial, government, school,
professional, hotel or gated communities and any other quality-sensitive, high-risk
environments such as prisons, airports, and train stations.
