Infant Optics Guide on Temperature Accuracy – Change/Switch from C to F and from F to C

In this post, I have shared details on how to change Infant Optics temperature on the parent unit from Celcius to Fahrenheit (C to F) and how to swtich from Farenheit to Celcius (F to C). I also share details of Infant Optics temperature sensor and the accuracy of the Infant Optics reading.

Below this temperature guide, I have a full review of the older Infant Optics DXR 8 and have compared it with other non-wifi monitors available in the market today. You can read the review of the Infant Optics DXR 8 Pro which is an upgrade to this model

Temperature Sensor not very accurate – Gives Wrong Reading

Having a reliable baby monitor with temperature sensors can come in handy for any parent purchasing a baby monitor to assist in SIDs and temperature-related risks. Infant Optics DXR 8 uses a precision temperature sensing technology that enables parents to view the temperature in the baby’s room either in Celsius or Fahrenheit.

The readings are shown on the screen (see the screen below for an example). The temperature sensor in the Infant optics DXR 8 is located in the camera and it should begin sensing the temperature as soon as the camera is powered. Sometimes the reading on the camera ar LL or HH and this basically says the temperature is too low (LL) or too high (HH).

To change the temperature from Celcius to Fahrenheit or vice versa, all you need to do is to hold down the short-cut button for at least three seconds and it will change the temperature. Some parents, especially those living in ventilated units have complained about the temperature accuracy of Infant Optics DXR 8. We’ll cover a sub-topic on Infant Optics temperature accuracy in the next section below.

Infant Optics Temperature Accuracy(HH, LL & Temperature Change from F to C or from C to F)

Infant Optics DRX 8 temperature accuracy

Are you wondering or surprised that the infant optics temperature is wrong or inaccurate? Several tests have indicated that Infant Optics temperature could have a deviation of 1 to 2 degrees as a result of heating caused by the camera that houses the temperature sensor, especially when it has been powered on for a long time. If the variation is more than 2 degrees, then read further.

What Could Be Wrong With The Infant Optics If The Temperature Readings Are Wildly Off?

Infant Optics can give you wildly wrong readings if you place it next to an AC or Air Vent unit as it will sense the cold and give you a reading indicating that the temperature is lower than it actually is in the entire nursery. This has made some parents suggest that Infant Optics may not be the perfect camera to sense the temperature in enclosed HVAC rooms. If you have more than one camera, you can add one of the cameras away from the air vent unit and this can guide you on the readings at any time.

If are wondering how you can change your Infant Optics temperature from one unit to another, i.e from Celcius to Fahrenheit or Vice versa, follow the steps below:

  1. Power on the parent unit of your Infant Optics DXR 8
  2. Select the ‘Short-cut’ button shown in the diagram below and hold it down for at least three seconds.

You can also follow the instructions in the video below describing how you can go about changing the temperature settings on your Infant Optics DXR 8. You’ll see the temperature units on the display change from one to another. If you see LL on your Infant Optics display, it means that the temperature is too low and if you see the Infant Optics display showing HH, it means that the temperature is too high in your baby’s room. Again, the temperature being displayed is that of your baby’s nursery and not of the camera.

Please note that all temperature sensing technology detects any heat in the surrounding so you need to mount your camera in a place that is far from any electronics that may be emitting heat.

What Makes Infant Optics Security Superior?

FHSS is a short form for Frequency-hopping spread spectrum (FHSS), a method of transmitting signals in one frequency band while switching/hopping from one channel to another. FHSS technology comes with all the benefits of digital signal transfer but in addition, it allows the signal to hop from one sub-frequency to another within the 2.4 GHz band as it moves the audio and the video signal from the transmitting baby unit to the receiving parent unit of the Infant Optics DXR 8.

The signal hops automatically and very quickly using a pseudo-random sequence known to both the transmitting unit and the receiving unit. It hops between 75 sub-frequencies within a period of 400 milliseconds! It also uses multiple access methods in frequency hopping code making it hard for hackers to get a hold of a particular signal and decryption code to allow them to watch or listen to your baby.

In addition to this security feature, FHSS technology enables Infant Optics to utilize several channels within the 2.4 GHz frequency by avoiding those with interference. Direct Sequence Spread Spectrum (DSSS) spreads the signal across a wide channel.

As of this publication, none of the baby monitors using FHSS technology have been hacked. You can find the list of those FHSS baby monitors here. Although not entirely impossible to hack Infant Optics DXR 8, it is very difficult for any hacker to succeed and they would probably look for another baby monitor that can be easily hacked, such as the wifi baby monitors.

It is important to note that FHSS technology does not provide encryption by itself but Infant Optics made built-in encryption. In addition to being the overall most secure baby monitor, we also crowned Infant Optics DXR 8 as the top FHSS baby monitor in our list of 11 best baby monitors using the FHSS technology in 2019. Some other secure baby monitors are analog baby monitors and digital baby monitors that use DECT technology.

Aside from its secure communication technology, Infant Optics was also the first baby monitor brand to introduce interchangeable lens in baby monitors. This brings us to our second reason for Infant Optics DXR 8’s wild success, the superior camera with interchangeable lenses.

Superior Camera With Interchangeable Lens

Infant Optics DXR 8 comes with a camera that allows you to interchange the lenses (normal, zoom or wide-angle) to fit the focal length you desire and the particular viewing angle appropriate for the baby’s nursery. The optical lenses are made of aluminum (great for night vision) and the zoom lens are telephoto lenses with great detail focus. A great combination of features makes Infant Optics just the right baby monitor to get the best view of your baby.

Here is some history of the interchangeable lens:

Infant Optics DXR 8 became the first baby monitor to introduce an interchangeable lens to baby monitor cameras. Between 1977 to 1984, Minolta perfected what came to be known as interchangeable lenses in cameras. The lenses essentially enabled photographers to change lenses depending on the type of picture they’d like to take. It was not until 2012 when the world first experienced the magic of the interchangeable lens in a baby monitor. Let’s go through each of the lenses:

Infant Optics DXR 8 comes with a camera that allows you to do the following at ease:

  • Control the type of video feed or pictures that the camera takes by switching from the available normal camera, zoom camera or the wide-angle camera. No other baby monitor allows you to interchange the active camera in the baby’s crib with ease and simplicity like the Infant Optics DXR 8. Regardless of the size or the layout of your baby’s crib or room, this baby monitor will allow you to choose a suitable camera lens that can give you the best view possible.
Infant Optics DRX 8 Default Lens

Default Lens:

When mounting your Infant Optics DXR 8 camera on the crib, you should position the aluminum lens to capture the entire crib. All lenses made from minerals work with a wide range of wavelengths but they are great within the infrared spectrum. We’ll go into detail later on why Infant Optics DXR 8 is great with night vision. The lens should allow you to view the baby on all sides of the crib. Most parents use this lens all the time and do not actually bother to switch to a wide-angle or zoom lens.

Infant Optics DRX 8 Wide Angle Lens

Wide-Angle Lens:

You can also switch from the normal lens to the wide-angle lens to get a view similar to the human eye, up to 170 degrees pan. The wide-angle lens zooms outwards giving you a bigger view, albeit with less clarity. If you have a very large room or if you’d like to monitor more than one baby, you can use the wide-angle lens to get a bigger, more expanded view of the room capturing more than one crib or capturing every activity in the room. The wide-angle lens is purchased separately. If you’re purchasing Infant Optics as a security camera, a wide-angle lens is appropriate as it gives you a wider view area. In 2018, Infant Optics was challenged by Eufy which introduced Eufy Spaceview, a baby monitor that comes with a wide-angle lens. Unlike Infant Optics DXR 8 that requires you to make a separate purchase of the wide-angle lens, Eufy Spaceview ships the wide-angle lens when you purchase the baby monitor.

Infant Optics DRX 8 Zoom Lens

Zoom Lens:

Infant Optics DXR 8 comes with an excellent telephoto lens that zooms inwards, making your baby appear closer and enhancing every detail at a further distance. A telephoto lens allows you to focus on the baby’s details while placing the camera away from the crib.
