Replace Logitech Alert 750n with a Raspberry Pi for door pinhole POE camera

26 Aug 2016

Hi guys,

This is my first post I've been watching the Ben Heck show a lot on Youtube and felt inspired to try a Raspberry pi project. When I moved into my apartment I ran a lot of Cat 6 cable through out the apartment including one through the front door so that I can replace the doorbell housing with Logitech Alert 750n(picture below). It was perfect because it fit in the opening and could be powered over the cat 6 cable using a POE injector on the other end near the router. Recently the camera stopped working, I read in many places that this model had a bad board and was known to fail often. I tried finding a replacement for it online, but Logitech stopped making them and the market price went up to $800 for this model. I figured I can go a different route and try to build a POE camera DVR using a Raspberry PI, a POE splitter, memory card and camera module.

I have not worked with the PI before even though I watched many videos. I wanted to ask for some advice about the setup:

1) Do I need to get any other parts?

2) What software do I need to make the PI work as a DVR?

3) what kind of housing can I use to both protect the setup and mount it to the door?

4) is there anything I can do with my broken Logitech Alert 750n or salvage any of the parts for this project?

Thanks in advance

Igor

dgbrown75022 on Ebay offered a repairservice for the 700e version. You could ask him if he's also repairing the n-Version.

Hi Igor,

For $800 you can get a far better cam than the logitech one. There is probably not much you can reuse from the existing one, but if you google 'pi security camera' (or add element14 to the search term to find this Raspberry Pi Smart Surveillance Monitoring System ) you'll find loads of projects using the Pi with its associated camera which plugs into a dedicated connector on the Pi (i.e. it is not USB interfaced, although there is nothing stopping you from finding a USB camera and plugging that in to the Pi if that is the route you prefer).
Bear in mind that it wasn't designed for acting like a security camera so it won't have the specialist features like motorised IR cut filters or even a lens mount etc. However you will have the advantage of extreme software flexibility since you can do a lot with Linux.
There is a project (part 1 only currently) here that uses power over the LAN cable HAL-CAM 9001 – Building a New Security Camera but its not standards-based PoE although that will come later.
