When it comes to hunting and outdoor activities, selecting the right thermal sensor is crucial. The most common thermal sensors on the market have resolutions of 1280, 640, 384, and 256, each favored for its own performance and features. The resolution of a thermal sensor refers to its thermal imaging pixel count, operating similarly to visible light cameras. A higher resolution means more observation and temperature measurement points, which helps detect and measure smaller targets and objects at greater distances. Nocpix will explore the differences between these four thermal sensors to help you make a more informed choice based on your individual needs and preferences.
Nocpix products are named according to different sensors and product functions, using a combination of product series name + sensor resolution + focal lens + LRF. There are four types of sensor resolution: S/H/L/P, which represent 1280×1024, 640×512, 384×288, and 256×152. For example, ACE S60R, ACE refers to product series, S refers to 1280, 60 refers to 60mm focal lens, and R refers to LRF. Let’s follow Nocpix to learn more about these four resolution sensors.
1280 Resolution Thermal Sensor
The 1280×1024 resolution thermal sensor is renowned for its outstanding image quality and clarity. This sensor provides extremely detailed images, allowing hunters to accurately detect and observe small targets, even when fully zoomed in. Nocpix’s Vista S50R thermal monoculars, ACE S60R thermal rifle scopes, and RICO 2 S75R thermal rifle scopes are all equipped with 1280 resolution thermal sensors. The Vista S50R monocular, featuring a 1280×1024 HD thermal sensor with a NETD sensitivity of less than 15mK and a built-in laser rangefinder, delivers excellent image performance under various weather conditions. Nocpix’s self-developed Gen-2 HD sensor ensures high-quality images, offering 1280 resolution with a smooth 50/60Hz refresh rate. This means sharper details, faster image flow, and precise tracking, even in fast-moving situations. Unlike typical sensors that struggle with noise and detail loss, the Gen-2 delivers consistently clear, high-quality performance, making it a reliable choice.
640 Resolution Thermal Sensor
The 640 resolution thermal sensor (640×512) strikes a good balance between performance and cost-effectiveness. Nocpix’s QUEST H50R thermal binoculars, ACE H50R thermal rifle scopes, and VISTA H50R thermal monoculars are all equipped with 640 resolution sensors. The ACE H50R thermal rifle scope features a 640×512, 12μm thermal sensor with NETD≤15mK, delivering excellent thermal sensitivity and clear images in any environment. Its 50mm F0.9 increases the light reaching the sensor by 20% compare to standard F1.0 lens. Combined with high-transmittance lenses, it is able to produce brighter and clearer images. With a 2560×2560 circular AMOLED display and a 1-3x ocular zoom, users can get a clearer and more detailed observation experience through the eyepiece.
384 Resolution Thermal Sensor
The 384 resolution thermal sensor (384×288) is a mainstream option that provides basic thermal imaging capabilities. While its resolution is relatively lower, it still offers effective thermal wdetection and target recognition. Hunters with limited budgets or those just getting started with thermal imaging products will choose this model, which costs around €2,000 or even less. Nocpix’s Bolt L35R thermal rifle scopes and Lumi LRF L35R thermal monoculars both use this sensor. The Lumi LRF L35R features a 384 resolution making it ideal for hunting and open areas, particularly forests and grasslands. Its compact and lightweight design makes it easy to pair with other equipment, perfect for quick target identification in grasslands and fields.
256 Resolution Thermal Sensor
The 256 resolution thermal sensor (256×152, with a total of 49,152 pixels) offers lower resolution but still provides useful images for some applications. Devices equipped with this sensor are typically more affordable. Nocpix’s newly launched Bolt P25R thermal rifle scopes uses a 256 resolution thermal sensor and integrates a laser rangefinder for precise distance measurements and reliable visual performance. This product is the only scope in its category that meets the clarity, design, functionality, and reliability requirements, priced under €1000, making it an excellent option for beginner thermal hunters or those on a budget.
How to Choose the Right Thermal Sensor
When selecting a thermal sensor, you need to consider your needs, preferences, and budget. The 1280 resolution thermal sensor offers unparalleled image quality and clarity, making it ideal for users with high-performance demands. The 640 resolution thermal sensor strikes a good balance between performance and cost-effectiveness, making it a reliable choice for hunters. The 384 resolution thermal sensor is a great option for users with a limited budget, while still providing effective thermal imaging capabilities. The 256 resolution thermal sensor is the most affordable and is ideal for entry-level devices.
Nocpix offers a range of products equipped with different thermal sensors, each with its own unique advantages and suitable applications. Understanding the differences between these thermal sensors and making a decision based on your specific needs will help you choose the best thermal sensor for you, enhancing your hunting experience.
