RPi3でRTSPを見る: Reboot シリーズは，まとめちゃった<\/a>んですが，完了していません．<\/p>\n\n\n\n

まずどうでもいい話からですが，Raspberry Pi 3 Model B (RPi3)と同+ (RPi3+)を持っているので，専用電源も2つあったはずなのに1つ見つかりません．<\/p>\n\n\n\n

いろいろ探しても見つからないので，強制空冷のケースと一緒に某通販サイトの出店者に注文しました．なんか，買ったら出てきそうな予感はしていました．<\/p>\n\n\n\n

実際その予感は当たりました．買う前にいろいろ探したつもりですが，新しい電源が届いた数日後，全くありそうもなく探していないところから出てきました．<\/p>\n\n\n

Raspberry Pi 3用のACアダプター<\/figcaption><\/figure>\n<\/div>\n\n\n

写真の左がその「出てきた」RPi3(+)専用と銘打たれていた5V3AのACアダプターで，プラグはMicro USBです．<\/p>\n\n\n\n

右が今回買ったもので，5V3AのUSB電源です．これに，中間スイッチの付いた，Micro USBのケーブルが付いてきました．そのままほったらかしておくと，いくつもある普通のUSBアダプターと紛れてしまうので， “RPi3用” とテプラ<\/a>を貼っておきました．USBアダプターなので，USB-Cのケーブルを使えばRaspberry Pi 4 Model Bにも使えますし，もちろんその他のUSB機器にも使え，まあつぶしがきくので良しとします．<\/p>\n\n\n\n

さて，このプロジェクトが難航というか頓挫している最大の理由は，Real Time Streaming Protocol (RTSP)の動画を流すカメラの故障です．<\/p>\n\n\n\n

買ったときからあんまり調子が良くなくて，新しいfirmwareが発表される度に今度は良くなると期待していましたが，裏切られ続けてきてます．<\/p>\n\n\n\n

最新のfirmwareが最悪で，8月14日に接続が途切れてから，何度電源リセットをしても，接続先のルーターのリスタートをしても，接続が復帰しません．<\/p>\n\n\n\n

一昨日から，電源を完全に切っています．心証として，暑い時期のほうがより調子が悪いので，少し涼しいときに電源を入れて初期化して再設定してみます．<\/p>\n\n\n\n

それでだめ（たぶんだめ😓）なら，もう1台同じものを買うか，別のものを探すか迷っています．<\/p>\n\n\n\n
