Please note that this is a DIY camera, not a commercial product. We have done our best to make the instructions easy to follow, but there are some fiddly steps and it may take some experimentation and tinkering to make things work. You can download the Infrared Night Camera Instructions as a printable booklet here.
The parts you need to make the camera can be ordered from online retailers or bought in electronic hardware stores. Follow the links below to find out more about each part, some links lead to retailers but you may need to shop around to find the best deal for each part. Prices can vary considerably, but it should be possible to source a complete kit for around £40.
Note: the standard infrared camera requires no soldering!
Useful Tools and Accessories
Computer with WIFI access
Smartphone or tablet (optional)
Hot glue gun / Sugru / sealant
Silica gel pouches
Soup or sauce container for use as a lens shield
Camouflage tape (optional)
* There many different versions of infrared camera modules for Raspberry Pi on sale, be sure to get one with a cable compatible with Raspberry Pi Zero W
** The cost of power banks vary enormously, so do shop around. In addition, the capacity of the battery depends on how long you wish to leave your camera running. Some users are happy with 2 or 3 hours of usage from a pound-shop battery, while others prefer that the battery lasts over a day - so finding the right balance may take some experimentation.
*** Please Note: Some retailers supply SD cards in bundles the have an operating system called NOOBS preinstalled. This is not the right software for the cameras, and will be deleted automatically when you install the My Naturewatch Camera software on them (steps 1 -5 below).
There are six stages to making a My Naturewatch Camera.
Download the Software. The camera software needs to be installed on the SD card from the Internet. The Raspberry Pi Zero will read the software from the SD card to become a My Naturewatch Camera.
Assemble the Electronics. Here you will attach the camera to the Pi Zero. It's a little fiddly, but with patience you'll manage.
Name Your Camera. You can give your camera its own name and password.
Test Your Camera. Now you can power up the camera and see if it works.
Make the Camera Housing. Assuming you have a working camera, it's time to make a weather-resistant housing from household materials.
Assemble the Camera. Finally, you're ready to fix the camera inside the housing and try it out!
The whole process should only take 60 - 90 minutes.
Download the Software
Copy the camera software to a micro SD card (up to 1 hour). This software contains the operating system for the Pi Zero and an application that controls the camera. This bundled software is often referred to as a ‘disk image’.
Downloading the software and installing it on the SD card can take a while, depending on things like the speed of your internet and the computer you’re using. You can skip to Step 6 and continue working through the ‘Assembly’ and ‘Housing’ sections while you wait for actions in steps 1-5 to complete if you like.
1. Download the disk image (a 4.5 GB file) from the following link (up to 1hour download depending on the speed of your connection):
2. Take note of the location where the disk image is being saved on your computer.
3. Download an application called ‘Etcher’. This will copy the disk image to the micro SD card safely and easily (note: Etcher refers to the process of copying the disk image as 'flashing the drive').
4. Insert the Micro SD card into your computer - using a micro SD adaptor* (your laptop may have a built-in SD card reader), or an external micro SD reader
5. Using ‘Etcher’ software - select the disk image as ‘Image’ and the micro SD card as ‘Drive’, then press ‘Flash’. This step takes around 15 minutes. (Helpful Tip: the time can be shortened by deselecting "Validate write on success" in the Etchers settings menu, found by clicking the cog on the top right of the app)
Note: After Etcher has 'flashed the drive', Windows based computers will sometimes ask if you would like to format the SD card. If this happens, click 'no', otherwise the software will be deleted.
* When using a micro SD adaptor, be sure that the copy protection switch is unlocked.
Assemble the Electronics
6. Make sure your USB Power Bank is fully charged by plugging it into the mains via its cable and plug. Most batteries have LED lights to indicate level of charge
The camera connector is very fragile, so take care on this step!
7. To attach the camera module to the Pi Zero: unclip the black locking strip away on the white camera connector on on the Pi Zero - it should move outwards by 1mm and feel loose. Now insert the camera module ribbon under the black strip and into the white connector - the metal side of the camera ribbon should face toward the green board. Secure the ribbon by re-clipping the black strip towards the white connector.
If the connector breaks, you can hold still use hot glue or tape (not superglue) to hold the cable in place – but its best to be gentle and patient to avoid breakage.
8. In order to dissipate heat from the processor it is necessary to attach a heatsink. Raspberry Pi heatsinks generally have self-adhesive tape already applied. Peel away the protective layer of the tape and carefully stick the heatsink squarely over the large black chip on the Pi Zero.
In a previous version of these instructions we suggested supergluing a bolt to the processor as a cheap alternative to a commercial heatsink, we have now changed this advice because we found that thermal performance varied considerably depending on the material of the bolt and users reported mixed results.
The ribbon cable of the camera can easily detach from the PI Zero. We recommend mounting the camera and Pi Zero to a piece of card to protect the connection.
9. Use a stiff piece of card appropriate in size to the container you plan to house the camera. Click here for a printable outline drawing of the card used is these images, this shape is optimised for use with the Sistema Kip It 900ml cracker box we often use for the daylight camera, although in the example below we use a takeaway food container. In this version, the camera and Pi Zero are mounted on opposite sides of the card.
Use double-sided sticky pads to mount the Raspberry Pi to the card, here we have mounted it offset to the centre to allow space for the USB power lead.
Carefully fold the camera cable ribbon cable at its narrowest point around the top of the card, remove the protective layer of the sticky tape that is factory mounted on the back of the camera, and stick to the other side on the card. A small piece of masking tape can also be used to secure the camera ribbon.
Tip: If you plan to use a large container, the Raspberry Pi and camera can all be mounted to one side of a piece of card.
Rename Your Camera
The My Naturewatch Camera creates it's own wireless network allowing you to control it through a web browser on any smart phone, tablet or computer connected to it. Here you can change the name of this wireless network or if you are happy with a default name of 'MyNaturewatch' skip to step 13 .
10. View the contents of the micro SD card on your computer by selecting 'boot'.
11. In 'boot', open ‘_naturewatch-configuration.txt’. Tip: You may need to eject the Micro SD Card and reinsert it again before you can view the contents
12. The name and password of your Camera can be edited by rewriting the appropriate lines which are by default ‘MyNaturewatch’ and ‘badgersandfoxes’ respectively. There is no requirement to change the default names, but the option is available to provide choice or for situations where there is an intention to run multiple cameras simultaneously.
Please note that any new name password must contain at least eight characters of letters or numbers. Be sure to save the file if you make changes.
Note: 'Connect to home network' is for a future feature.
Test Your Camera
13. Insert the micro SD card into the silver socket on the Pi Zero - the metal contacts on the SD Card should face toward the green board.
14. Power the assembled unit by connecting the USB power bank to the Pi Zero. The small end of the USB cable plugs into the ‘PWR’ port on the end of the Pi Zero closest to the camera. The large end of USB cable plugs into the USB battery (or any USB power source).
15. Allow 60 seconds for the Pi Zero to boot up. The green light on the Pi Zero will flicker to indicate processing. Once the system has started, a red LED on the camera ribbon cable will light. If the red LED does not light, it is likely that the camera ribbon cable is not correctly seated in the Pi Zero and so repeat step 7.
16. On a smartphone, tablet or computer connect to the camera's wireless network. The wifi network name with either be 'MyNaturewatch' or the unique name you gave it in step 12. The wifi password will either be 'badgersandfoxes' or the unique name you gave it in step 12.
17. Once connected with your device, open any internet browser and visit the following webpage to access the camera interface:
You should see the live preview feed from your camera along with the following simple control buttons: Start Image Capture, Image Gallery and Settings.
Tip: if your browser rejects the URL try entering the My Naturewatch Camera IP address instead: 192.168.50.10

Make the Camera Housing
As with the daylight camera, the infrared camera will need to be protected from the elements by some sort of housing. The possibilities are endless, from ziplock bags to more elaborate constructions. We show you one possibility here using takeaway food and soup containers, but feel free to improvise. We also have a blog post that demonstrates how to separate the infrared lamps from the camera lens to produce cinematic lighting effects.
The camera works best if the lens is not behind the housing material, no matter how clear that may seem. We drill a hole in the main housing and use a rain cover to protect the lens.
18. Carefully cut around the bottom of a supermarket soup container or similar to make the camera lens / infrared lamps cover (always take care cutting plastic).
19. We have found that the easiest way to mount the infrared camera is to make three holes adjacent to one another that allow the camera lens and the two infrared lamps to pass part-way through. In this example, we have made the holes using a 20mm forstner drill bit in the lid of a takeaway food container, though you could also use a small drill, scissors or scalpel to achieve a similar result (always take care cutting plastic).
20. Position the cover you made earlier over the lid of a takeaway food container and make a waterproof seal using a hot glue gun, Sugru or household sealant.
Assemble the Camera
21. Pass the infrared camera unit through the holes that you made in the lid of the takeaway container. Secure with masking tape or similar, along with the cardboard Pi Zero mount inside the takeaway container. Add a silica gel pouch and connect the battery, place the lid/cover assembly over the container. Warp with camouflage tape (which is and reuseable and can be repositioned).
22. Please go to the Using Your Camera page for instructions about how to set your camera up.
Make sure to read through the steps above and do not forget to read the Using Your Camera page.
