HomeKitCam

A project to make a Raspberry Pi driven, HomeKit Enabled camera.

This project aims to make a simple DIY HomeKit enabled camera using only a Raspberry Pi and the Raspberry Camera Module. The software is based on the HAP-NodeJS HomeKit API by KhaosT.

Requirements

One of the aims of this project is to be as simple as possible. You will only need:

• A working Raspberry Pi (the newer, the better), configured with a standard Raspbian installation
• A Pi Camera Module
• A suitable usb power adapter to power the Pi

Installation

To install, clone the project into a folder. Then cd to that directory, and run npm install to install all the necessary packages.

Starting HomeKitCaM

The camera can be run by running the command: node PiCamera_accesory.js

On any iOS 10 device, open the Home app and add a new accessory. The Raspberry should show up as 'Pi Camera'. When asked to scan the HomeKit accessory code, choose to manually enter a code and enter 031-45-154. After that, the pairing should be successful and the camera should start to send screenshots to the Home app.

homekitcam's Issues

Will not start

I cloned this down and ran npm install

when running node PiCamera_accessory.js I get the following output

/home/pi/HomeKitCam/PiCamera_accessory.js:25
let sessionIdentifier = uuid.unparse(sessionID);

Single frame is streamed then times out, not a performance issue

Hi.

This is exactly the project I've been meaning to use my Zero W for. I managed to get npm and everything setup for HomeKitCam but I'm finding the stream from iPhone shows the 1st frame when connected, then times out.

The npm/PiCamera_accessory.js script shows the following options when I connect with my iPhone:

bitrate: 299
avconv stream: -f video4linux2 -i /dev/video0 -s 640:480 -threads auto -vcodec h264 -an -pix_fmt yuv420p -f rawvideo -tune zerolatency -vf scale=w=640:h=480 -b:v 100k -bufsize 200k -payload_type 99 -ssrc 1 -f rtp -srtp_out_suite AES_CM_128_HMAC_SHA1_80 -srtp_out_params wuxFurc9azRuIgjC98gWfSsmwIDjOdBtRpfu1UtQ srtp://192.168.2.133:64011?rtcpport=64011&localrtcpport=64011&pkt_size=1378

My iPhone shows a frame, then nothing happens until I finally get a "No response" message.

I ran top on another term on the Zero and there's no CPU usage after the 1st frame. When the connection is established, the avconv process will pop at the top with 20% CPU, then disappear from the list while the streaming stalls out.

Is there anyway to figure out the problem that avconv is happen?

How to get working on a Mac with usb camera?

How could I get this to work on a Mac? I prefer to run it on this type of machine because hopefully the greater power will provide less latency in the stream. Any help is greatly appreciated.

Painfully slow stream

I use the HomeKitCam on my computer with a microsoft Cinema camera and it works perfect.
No i try to do the same thing with my raspberry pi and the picam and get painfully slow laggs on the stream i talking about one second in real time takes 20 seconds to watch in the home kit app

I have tried to change the ffmpegCommand params without result. is it really possible to stream with ffmpeg and raspberry pi Model B?

No snapshot over cellular

When I use a raspberry zero wifi and raspberry camera with homekitcam everything works fine when at home with wifi. But when using cellular the snashot dont refresh and the streaming dont work.
Any clues on why this happens?

cant run node PiCamera_accessory.js ? ideas?

If it could help, I have Raspbery PI Zero W with Camera v2.1 and 16GB SD Card, clean Raspbian Stretch Lite installed from raspberrypi.org with enabled camera using sudo raspi-config and HAP-NodeJS installed as recommended on instalation guide.

Video stream not working?

This might be a duplicate of #3, but I'm having a slightly different issue. The snapshots work fine with the camera, but the stream does not load at all. I can wait as long as I want, but the camera will still keep trying and the script will still keep printing the command over and over again. Has anybody gotten this to work?
