A unique aspect of Opgal’s service is our company’s willingness to work with individual consumers to address your personal needs, and custom design solutions accordingly. We understand how vital it is for you to attain a system that works for you and we will strive, to the best of our abilities, to tailor your desired system/s to your specifications. Please contact us so that we can begin working together to design the system that will suit you and your specific requirements.
How are your HD systems different from your standard systems?
Our HD systems are equipped with CMOS day sensors, which are designed specifically for high definition video recording. CMOS sensor technology allows for pixel amplification, which provides the camera with the ability to capture more data and respond to situations quicker and more efficiently. The High Definition video option also reduces background noise and generally uses less power than other systems. As a result, the HD system has a host of benefits, capturing more information in a shorter amount of time while still decreasing power usage and noise interference.
How do the fire/hot spot detection systems work?
With Opgal’s fire/hot spot detection camera systems, fires can be prevented, as the camera is built to detect high temperatures and set off an alert so that the situation can be assessed. The fire and fire risk detection systems use heat detection analytics to increase the security and safety of people and equipment in your facility. These systems are designed with fire detection capabilities that range from several centimeters up to four miles. They can be used in hazardous environments and are effective both indoors and outdoors.
Why should I choose an Opgal system over the competition?
The Opgal system is the recommended brand for those looking for quality, and service that easily surpasses other leading companies in the thermal imaging market. The developers at Opgal constantly strive to remain at the cutting edge of new technological developments in the field, building on their existing knowledge base to continue developing new features and better operability. Opgal combines practicality, innovation and the highest quality technologies to build and improve on our work, our international success serving as proof that our products have set a new global standard.
What type of optics do you offer?
Opgal offer a variety of optics ranging from athermal lenses with fixed focus, dual field of view lenses (wide and narrow FOV) and continuous motorized lenses that can offer extreme zoom capabilities while maintaining low weight and power consumption.
Are the thermal camera systems made by Opgal export controlled?
Some of the thermal camera systems manufactured by Opgal require an export license under the International Traffic in Arms Regulations (ITAR) and a signed end-user certificate. Reselling or re-exporting these devices is prohibited by law.
Does Opgal offer thermal OEM modules?
Opgal offers a full range of OEM products to suit your every thermal imaging and optic need. These customizable solutions enhance situation awareness and vision enhancement, and each thermal camera is designed to fill your individual requirements in a cost effective way.
General Thermal Cameras Technology FAQ
What is ONVIF compliance and why is it a benefit in a thermal camera system?
ONVIF is the Open Network Video Interface Forum, which develops and releases the standards for IP-based security items. ONVIF provides protocol specifications that allow for interoperability of ONVIF devices, so that when you need to add components to your security network, everything will work together.
What are LED Illumination and Active Laser Illumination?
LED Illumination and Active Laser Illumination are two types of near-infrared technology used with CCD and thermal cameras that covertly illuminate the area in front of the camera to assist with accurate identification and assessment even in total darkness or long distances. They allow for details such as faces or even written word to be easily recognized from afar and/or at night.
What is an IP system? Why do I need one?
IP systems are designed to be able to stream video back to your video management system, and have the stream be accessed remotely. Manufacturer compliance with certain industry standards – such as ONVIF (Open Network Video Interface Forum) – allow you to integrate all security products that are ONVIF compliant, despite having being developed by various manufacturers.
What is NUC?
NUC are non-uniformity compensation (NUC) coefficients which are factory-calibrated to maintain high image quality on thermal cameras. The coefficients comprise a NUC table and generally work within a specific subset of the total operating temperature range. The camera works to select the best NUC table based on its temperature.
What is the difference between a 9Hz and a 30Hz refresh rate?
The Hz number represents the frame rate – the amount of times per second that the infrared detector captures images on a thermal camera. In a 9Hz camera, the detector can create 9 images per second, while in a 30Hz, the detector creates up to 30 images a second.
Not to be confused though, regardless of the frame rate, all thermal cameras contain the same infrared properties.
Can Thermal Cameras Operate During Daytime?
Regular digital camera sensors detect light, whereas thermal imaging camera sensors detect heat. Thermal imaging cameras contain a special lens which focuses the heat, or infrared energy which is given off by an object onto a detector which is sensitive to heat. So, being that it is unaffected by light, thermal imaging will work just as well in daylight as in complete darkness.
How Does Thermal Imaging Work?
Thermal imaging cameras, also known as infrared cameras, detect the heat given off by an object or a person. Like visible light cameras, these cameras have lenses, but the thermal imaging lens focuses the infrared energy waves it detects onto an infrared sensor array. The infrared energy is converted into electrical signals through thousands of sensors on the array, creating a video image. A “thermal profile” is then measured and displayed, comparing the temperature of the objects or people captured by the infrared camera to the temperature of their surroundings.
What are the Different Uses For Thermal Imaging Cameras?
Thermal imaging cameras have a wide variety of uses, including but not limited to defense, security, mobile, aviation, industrial and personal use. These cameras enhance awareness and surveillance capabilities with wide fields of viewing even in situations with little or no visibility, and increase security with super clear video even in harsh weather conditions. The Android thermal cameras can be used both indoors and outdoors to reveal mold or wildlife hidden in the environment. Optical gas imaging cameras can detect gas leaks and help prevent major disasters in industrial environments.
What are Thermal Imaging Cameras?
Thermal imaging cameras use infrared rays to create the images that they capture. Like a regular camera, a thermal imaging camera forms images, but while a normal camera captures the light that enters the lens to reveal an image, thermal imaging detects heat. Depending on the camera’s particular design, the heat that is detected can reveal a load of information regarding its surroundings.
What is the Difference Between Cooled and Uncooled Thermal Imaging Cameras?
In an uncooled thermal imaging camera, the infrared-detecting elements are contained in a unit that operates at room temperature. The more common type of thermal imaging devices, uncooled systems operate quietly and can be activated immediately. Cooled thermal imaging devices have their detectors stored in a unit that cools them to -32 degrees F (0 degrees C) or lower. While these cryogenically-cooled systems have incredibly high resolution and sensitivity as a result of their elements being cooled, they are more expensive and are more susceptible to wear and tear from use than uncooled cameras.
