The hybrid Viewtron DVRs that are included with each system also work with standard definition analog CCTV cameras, 4MP cameras, 8MP / 4 K cameras, and network IP cameras. These systems are simple to wire and setup. The HD cameras are AHD (analog high definition) type cameras which are hard-wired to the DVR using the same type of coax cable used by traditional CCTV cameras. The app can be downloaded from the Google Play Store, F-Droid, or as an apk, and the source code can be cloned from Github.The video surveillance systems on this page includeġ080p HD security cameras and HD CCTV DVRs that record up to 4K video resolution. You may want to check out the presentation slides for a quick overview, and visit the app page for more details.

But actually, the app was initially intended to protect journalists against raids, or more exactly record their occurrence (as proof), and is released by the Guardian Project that aims to “create secure apps, and open-source software libraries that can be used around the world by any person looking to protect their communications and personal data from unjust intrusion, interception and monitoring”. One of you first reaction might be: “cool! somebody may an app that would allow hackers or government to make spying on your ever easier”. Other people also comments what they did with theirs, for example setting up a Linux cluster with old TV boxes.Īnother way to recycling an old (Android) smartphone – albeit you could always buy an inexpensive one – is to install and run Haven, an open source app that transforms your phone into some sort of smart security camera, but instead of only using the camera from the phone, the app also logs audio events using its microphone (array), as well as data reported by sensors.

My own proposals included giving them away, reselling them on eBay, recycling them for other purpose like servers or download clients, or scavenging some parts.

About two years ago, I wrote a post asking what to do with old devices instead of throwing them away.
