A real time clock (RTC) - if you want to timestamp your footage and why wouldn't you?.3 Jumper wires to hook up the PIR sensor.16GBs or more and small form factors are recommended here. An adapter with a short cable length is ideal when it comes to positioning things in the casing. I use an Anker PowerCore 10000 due to its size and capacity. 8GBs should be adequate as we're going to store our footage on a removable device. Pi Zero camera cable - if using a Raspberry Pi Zero.See the section below for an explanation. Raspberry Pi camera module - there are several options available here depending on what time of day you want to capture footage.Raspberry Pi Zero W - you can use other models but the Zero W is cheaper than most and has built in WiFi which is extremely useful.A wireless network such as your home broadband.A computer connected to the internet with an SD card slot (or some other way of attaching an SD-card).Optional - Record in both daylight and at night.Include a removable storage system so that the camera could remain in place and have the storage drive replaced.Like the last project I wanted to achieve the following with my trail camera: Now in 2018, the Raspberry Pi Zero W is available which combines a tiny form-factor with built-in WiFi which makes the whole process of development far easier! Since the last guide there have also been updates to operating systems and some of the software libraries so now seems like a good time to re-vamp my how-to guide. In my last guide, I started my project with a Raspberry Pi B+ but alluded to using the smaller A+ and Zero models. Therefore, I wanted to see if I could build my own and work out the pros and cons of doing so both in terms of cost and functionality. There are many trail camera products already on the market - most of which are excellent but can come with a hefty price-tag. As a battery-powered, self-contained unit, trail cameras can be deployed away from power sources making them ideal for monitoring remote areas which sets them apart from other, similar 'webcam' style systems that are hooked up to mains power and the internet. For me, they are an invaluable tool for monitoring sites where I want to discover more about the activity of the wildlife in the area but can't commit to days on end keeping watch. Trail cameras have become very popular over the last 5 years across a range of applications.

This version takes into account the latest hardware and software updates.

This guide is an updated version of my popular how-to guide on building a trail camera with a Raspberry Pi.
