DIY Wireless Trailer Camera

If anyone is looking for an alternative to a more expensive, purpose-built horse trailer camera system, I ran a little experiment this weekend, when shipping to an event 6 hours away. The fact that my transmission line split less than an hour from the venue, and five hours from home, is neither here nor there, but at least my trailer camera experiment was what I would consider a 100% success!

Supplies: [LIST=1]

  • Battery-Powered WiFi Security Camera (I purchased this one)
  • Smart Phone with mobile hotspot functionality
  • Extra smartphone (I used my old Samsung S7 that I had lying around)
  • Suction Phone Mount
  • Car charger or USB charger for both phones to maintain power while driving [/LIST] Method: On WiFi at home, I downloaded the camera app and installed it on my spare phone. I paired the phone with the camera and confirmed it worked. Left the camera and spare phone to charge overnight, and headed to the farm in the morning.

    I used a very strong suction-mount phone holder and attached the camera to it in the trailer. The model camera I bought is actually threaded for a legitimate camera mount, so it is likely I will upgrade to a mount that can be screwed into the aluminum header in the horse compartment. However, for an experiment, the suction mount worked perfectly, regardless of some rough roads.

    I mounted the spare phone in landscape mode on my dashboard, turned on my mobile hotspot on my primary phone, and connected both the camera and the spare phone to the mobile network (fun fact: my mobile hotspot is named Silence of the LANS Mobile, heh). Bingo! I had a crystal clear picture and audio of my boy.

    Details:
    I have an aluminum Exiss 722 ST 2H BP. There is a tack room in front of the horse compartment. I do not have a bed cover on my truck bed. The camera has intercom functionality and night vision. I drove for 5 hours and experienced only the following minor issues:

    • The app crashed twice. Simply hitting the "reopen app" on the error screen resolved this.
    • Sometimes there was a bit of lag.
    • Sometimes the picture froze, never for more than 10-15 seconds.

  • Neat, that worked well, good picture, shiny horse.

    Neat! A while back I ran across and bookmarked a HOWTO for a setup that uses an automotive backup camera: https://www.youtube.com/watch?v=p6ZWOJY2gQI

    I’ll add yours to my notes… one of these days when I need to go somewhere again, this is definitely on my todo list.

    Love it! Will definitely be ordering one and trying this.

    Glad that worked! What I haven’t done, but have seen suggested is a Go Pro and the go pro app on your phone. I have a 3h slant and would mount it above the back door, looking forward. The downside is battery drain on the camera with wifi running, but most of my trips are 2h or less.

    I am sorry about your truck!

    when you’re using your phone as the hot spot, is that a heavy drain on your data?

    I have something similar (https://www.amazon.com/Magnetic-RVS-83112-WiFi-Rear-View-Safety/dp/B01N3UW99I) but it transmits its own Wi-fi signal so I don’t have to use my phone as a hotspot. I have it in the rear window of my 2 horse BP slant, and have no problem getting the signal from the front of the truck. The longest haul I’ve used it was 7 hours and the battery lasts at least that long.

    I just looked at my usage, and from 7a-11a I used 31MB for the mobile hotspot.

    I love the idea of the devices with their own WiFi signal! Very cool!

    Has anyone had success using a baby monitor? How did you power the camera inside the trailer?

    I highly recommend the iball camera. I really like having the monitor separate from my phone, it stays on and I can just glance down at the big guy. I added magnets to the outside of my trailer so it stays on very well and then I adjust it for backing and hitching.

    Great idea OP… and one that can be executed very economically with no hard-wiring of equipment.
