1080p HD video for crisp, detailed footage
Experience the difference that full 1080p HD video makes. Our advanced cameras use standard coaxial cable to carry high definition 1080p (1920 x1080) video to your HD DVR. This resolution ensures detailed live viewing and recording that leaves nothing to the imagination.

Advanced motion detection (single channel)
Be alerted when motion is detected on your property with advanced motion detection capabilities. One of the channels of this DVR allows for advanced person/vehicle detection. When installed in high-traffic areas, like front door or driveway, this feature helps to reduce alerts and false alarms. Important motion events that are recorded can easily be found using the Smart Search feature, which organizes events by type (e.g. person/vehicle motion vs. general motion, etc.)

Long range night vision
Stay connected to what matters most at all times of day with professional-grade night vision. Our infrared (IR) LEDs provide unparalleled performance in the dark, allowing you to clearly see up to 130ft (40m) away in regular nighttime conditions, and up to 90ft (27m) away in total darkness. The integrated infrared cut filter switches on and off between day and night, ensuring accurate color reproduction in all lighting conditions.

Fully weatherproof for outdoor use
This rugged, weatherproof camera is IP66-rated to ensure protection against all types of bad weather. Be it heavy wind, rain, or snow, we've engineered our cameras to withstand extreme temperatures for use in the most unforgiving of North American climates. These all season security cameras also feature a cable pass-through design that keeps power and video cabling concealed, as well as a durable yet lightweight Polycarbonate housing, to prevent vandalism.

• 140 Degree F | 60 Degree C Heat Rating
• -22 Degree F | -30 Degree C Cold Rating
• IP66 Weatherproof
