Camera maintenance and care tips

Digital cameras, like most electronic devices, need extra care when being handled. They have sensitive parts that can be damaged by improper handling.

These are the most common tips that can help you maintain your camera so that you can use it for a much longer time:

Avoid dirt and sand

Cameras are sensitive, especially their lenses.

Always clean the lens and the camera body with a clean cloth before you use it and avoid shooting in dirt and sand for long hours as much as possible because the camera lens is bound to easily catch dust.

Be extra cautious when shooting pictures on a windy day at the beach, where sand can blow with excessive force.

Also, avoid opening the battery compartment on such days. Or find a spot indoors or an area where you can safely interchange the lens and replace depleted batteries.

Avoid touching the lens and LCD

Your sensor is the brain of your camera, and it's completely possible to cause irreparable damage which is why these steps are so important.

Oils from your skin smudge the lens and LCD, eventually causing permanent damage. Clean the lens and LCD with a microfiber cloth when you see a smudge from your fingertips.

Avoid touching the sensor or cleaning it too much - because, realistically, it probably won't need it that often.

Avoid Exposure to Direct Sunlight for Long Periods

When the camera is exposed to direct sunlight for hours at a stretch, the seals that keep out dust and moisture can dry out and the lubrication on certain parts can evaporate.

Not just this, it can also overheat the battery, which is never good for any electronics product. You could instead use filters to protect your DSLR camera lens from direct sunlight.

Filters reduce the amount of light from entering the camera lens.

Battery Maintenance

When you see your battery life degrading, do not wait till it’s fully dead. Instead, purchase a new battery.

Also, never place batteries in places where the temperatures may go higher than 40°C.

This could cause malfunction and endanger the camera. When you are done shooting, turn off your camera instead of hanging it around your neck while it is turned on.

Also, ensure that flash is disabled for daylight shots.

Extended Warranty Plan

Just like your mobile phone or tablet, digital cameras too come with just 1 or 2 years of manufacturer’s warranty.

Since a DSLR is more expensive and a long-term investment for many, it is wise to get it covered with the extended warranty plan.

If you can’t imagine your trips, parties, or other special occasions ruined without your camera, we recommend you buy an extended warranty plan.

What is difference between Infrared Thermometer and Thermal Imaging Camera

10th May 2020

"Both work on the same basic principle: sensing an object's infrared radiation and translating it into a temperature reading but that's where the similarities end."

We’ll cover how infrared thermometers work, different types of IR thermometers, their pros and cons, and usage tips. Infrared thermometers are used in different industries and work environments to determine the temperature of objects from a distance. The distance can range from an inch to miles.

How Infrared Thermometers Works

Infrared radiation is a type of energy that is invisible to human eyes but we can feel it as heat. If you take a look at the electromagnetic spectrum, the infrared band sits just outside the range of the visible light. All objects having a higher temperature than absolute Zero emit infrared radiation. The hotter the object, the higher the frequency of the infrared radiation. Infrared temperature sensing devices detect the infrared radiation frequency and convert that into a temperature reading. Infrared radiation is one type that occurs within the electromagnetic spectrum; other types include visible light, x-rays, and microwaves.

The infrared thermometer uses a sensor called a thermopile which turns the incoming infrared radiation into heat using tiny thermocouples. The thermocouples convert that heat into an electrical signal which is measured and displayed on the screen in the form of the temperature reading. While Infrared Thermometer is a reliable and cost-effective way to get a non-contact temperature reading, it can only read the temperature for a single point. If you need a measurement for a larger area, you'll have to take multiple temperature readings.

Thermal Imaging Camera uses a focal plane array sensor. A typical Thermal Imaging sensor has pixel dimensions of 640 x 480 and each pixel acting as a sensing element, this gives you over 300k individual points on each thermal image or video. This creates a supercool thermal image from the infrared spectrum. And because of this advanced optics Thermal Imaging Cameras can detect temperature accurately for much greater distances.

Uses of Infrared Thermometers

Infrared Thermometers are widely used by different industries such as Automotive, Food, Energy and Medical. In medical this time widely used to measure the body temperature for fever of person by a medical professional.

How to Use an Infrared Thermometer

It's very easy; you only need to fix the batteries in their compartment and activate the desired temperature unit (Celsius or Fahrenheit).

Turn on the device by pressing the power button and aim the gun to the surface you want to measure the temperature.

Be sure to stand close to the object or within the DS ratio indicated by the manufacturer for accurate readings.

Pull the trigger to observe the reading on the digital display on the thermometer.

Types of Infrared Thermometers

Modern infrared thermometers mimic the same concept, but numerous advances in technology have introduced sophisticated devices to widen the scope of their applications. As such, detectors are designed to match specific applications to improve performance.

There are three types of infrared temperature measurement devices that are widely available today:

Infrared scanning systems: the devices scan larger areas and are used in manufacturing processes that involve conveyors, e.g., when continuous piles of objects move along a large sheet of metal from an oven.

Spot infrared thermometer: these kinds display the temperature on a particular spot on a surface., sometimes referred to as Infrared Gun.

Infrared thermal imaging cameras: these kinds use cameras to measure the temperature at different points over a larger area to create two-dimensional images called thermograms. The technology applied to the devices is more hardware and software-intensive compared to regular infrared thermometers.

Before buying Infrared Thermometers you need to know

Emissivity: It refers to the efficiency with which an object absorbs or emits infrared energy. The values range from 0.0 to 1.0. Objects that have an emissive value of 1.0 are called perfect emitters as they radiate 100% energy. An efficient infrared thermometer should factor in this feature based on the type of object in question because various surfaces emit radiation differently.

Accuracy and Speed: Effective IR thermometers deliver temperatures fast and accurately. Advanced versions factor is adjustable emissivity for more accurate readings. Experts allow a +1% margin of error when using professional IR thermometers and +2% for less expensive devices.

Temperature Range: The primary factor here is whether the thermometer is used for professional or home-based applications. For regular use, e.g., around the house, a temperature range of (-58 to 1022 degrees Fahrenheit or -50 to 550 degrees Celsius) is ideal.

DS Ratio: The distance to spot ratio affects the accuracy of the readings from the thermometer. The rate is determined by the size of the area being measured in relation to the distance. For example, if an object has a D/S ratio of 10:1 and it is 5 inches in size, the maximum distance the thermometer can accurately measure the temperature is within 50 inches. Distances larger than that range will be inaccurate as the IR thermometer will include the temperature of the surrounding objects and surfaces.

Warranty: A warranty is a good indication of a high-quality IR thermometer. The period can range from 90 days to 5 years based on the manufacturer.

So if you just need to do some non-contact temperature spot-checking for daily use Infrared Thermometer is good but if you really want to look at the bigger picture for better temperature profile of employees and visitors for offices/corporate/factories/hotels/hospitals/restaurants then a Thermal Imaging Camera offer robust sensing imaging.
