Dark 30 Defiance 640 PTZ - Further Information
The Dark 30 Defiance 640 PTZ is a professional vehicle-mounted thermal imaging camera system designed for hunters, gamekeepers, deer managers, pest controllers and estate professionals who need to scan large areas quickly without relying on a handheld thermal monocular.
Built around a high-resolution 640 × 480 thermal sensor, sensitive <30mK NETD detector and 32mm F1.0 germanium objective lens, the Defiance 640 PTZ provides reliable heat detection out to 1140 metres. Continuous 360° rotation, remotely controlled pan and tilt, and a wide 20° horizontal field of view make it particularly effective for searching fields, woodland edges and large areas of open ground from the comfort of a vehicle.
For professional fox control, deer management and nighttime wildlife observation, the Dark 30 Defiance effectively turns a 4x4 or estate vehicle into a mobile thermal observation platform.
640 × 480 High-Resolution Thermal Imaging
At the heart of the Dark 30 Defiance is a 640 × 480, 17μm thermal sensor with <30mK NETD thermal sensitivity.
Combined with a fast 60Hz frame rate, the system produces detailed, fluid thermal imagery when scanning for moving animals. The increased resolution of the 640 sensor also provides the detail needed to move beyond simply detecting a heat source and begin assessing what you're looking at.
For gamekeepers and professional pest controllers covering substantial acreage, this makes the Defiance 640 vehicle thermal camera an exceptionally capable tool for searching ground before beginning an approach.
Full 360° Thermal Scanning
One of the defining features of the Dark 30 Defiance PTZ thermal camera is its ability to continuously pan through 360 degrees.
Instead of physically turning yourself or repositioning a handheld thermal imager, the vehicle-mounted camera can scan the surrounding landscape while you remain inside the cab.
Tilt adjustment extends from straight down to 45° above horizontal, providing extensive coverage around the vehicle. Combined with variable-speed remote control, this makes it possible to rapidly search large areas before slowing the camera movement when a heat source requires closer examination.
Up to 1140m Thermal Detection Range
The 32mm F1.0 germanium objective lens provides an excellent combination of detection distance and field of view, with the Defiance capable of detecting a heat source at distances reaching approximately 1140 metres / 1250 yards.
A generous 20° horizontal field of view is particularly useful from a vehicle, allowing large areas of farmland and open countryside to be searched efficiently rather than restricting the operator to a narrow, highly magnified image.
Once something of interest has been detected, 1-8x digital zoom can be used for a closer look.
10.1" Full HD In-Vehicle Display
Rather than requiring the operator to continually look through an eyepiece, the Defiance 640 includes a large 10.1-inch 1920 × 1200 LCD monitor.
A direct HDMI connection between the thermal camera and display provides a low-latency thermal image, allowing the surrounding area to be observed comfortably from inside the vehicle.
This large-screen format is especially useful when working as a team. A driver, stalker, gamekeeper or pest controller can monitor the thermal image without repeatedly passing a handheld thermal device between occupants.
Five Thermal Colour Palettes
Different environments can benefit from different thermal viewing modes, so the Defiance provides five thermal colour palettes.
White Hot and Black Hot provide familiar high-contrast views that are particularly effective when rapidly searching for heat signatures, while Rainbow, Magenta and Green Hot provide alternative ways of displaying thermal information when examining a detected animal or object in greater detail.
Remote & Smartphone Control
The Dark 30 Defiance can be operated using its supplied wireless remote control, giving the user variable-speed control over the camera's movement.
There's also support for the Dark 30 App on iOS and Android, allowing compatible smartphones and tablets to control the PTZ system.
Useful functions include Sleep Mode and Return to Home, allowing the system to be quickly repositioned or placed into standby as conditions require.
Multiple Vehicle Mounting Options
Not every user wants to permanently modify their vehicle, so Dark 30 has designed the Defiance around several different mounting methods.
The supplied mounting system supports suction cups, powerful 100lb pull magnets and permanent bolt mounting, along with a 2-inch riser.
Temporary mounting makes the system particularly useful for users who want to transfer the camera between vehicles or remove it after a night's work, while permanent installation provides a dedicated solution for gamekeeping, estate management and professional pest-control vehicles.
Built for Year-Round Field Use
A vehicle-mounted thermal camera inevitably has to deal with rain, mud, dust and rapidly changing temperatures.
The Defiance uses a robust aluminium housing with an IP66 weather-resistant rating and is specified for operation between -20°C and +50°C, making it suitable for demanding year-round outdoor use.
The system operates from a 12V DC power supply, making it ideally suited to installation in a 4x4, pickup or other dedicated shooting and estate-management vehicle.
Ideal for Fox Control & Gamekeeping
Where the Dark 30 Defiance really stands apart from a conventional handheld thermal spotter is its ability to provide continuous, hands-free thermal observation from a vehicle.
For a gamekeeper covering large areas of farmland at night, the 360° PTZ system can be used to systematically scan fields and boundaries for foxes and other quarry. For deer managers, it provides an effective method of observing large areas and locating animals from a stationary vehicle before continuing on foot.
It's also a highly capable solution for wildlife monitoring, livestock observation, estate security, search operations and other professional thermal surveillance applications.
