## What is MimamoriKun?

Reuse the surplus smaho as a web camera!
If you can use WiFi, use the old smartphone immediately as a web camera!
Easy connection from the outdoor video confirmation!
Since it is connected with Peer to Peer, video is not transmitted to other than the connected smartphone!

Convenient for such cases!
· Pet watching while shopping a little
· Confirm that garbage has not yet been collected at the time of garbage disposal
· Monitoring the situation of home garden

When monitoring with a PC, you can see multiple smartphones at once!

■ Notes
· It is available on iPhone 4S iOS 9.3.5 or later.
· In hot places, the heat of smartphones will rise too much and the application may fall.
· Because monitoring connection becomes possible only when ID and password match, we recommend setting password as well.
· Browsers monitored by PC are confirmed to work only with Google Chrome.

In future I would like to implement the following.
· Improve it so that it can be displayed with the screen size of the smartphone because the picture is displayed small now
· Depending on some model and OS version, watching might end, so stabilize
· Improve energy-saving mode to make energy saving more possible if possible
· Display the remaining battery power to the monitor side if possible
· Added functions so that you can speak from the monitor side if possible

Since there is maintenance of the server, it may charge to future.

### 1/5 — 時間が経つとダメ

*2022-04-18, version 2.0.0*

最初は繋がってるけど時間が経つと繋がらない、対処法おしえてほしいです。

### 1/5 — すぐ落ちるし、

*2022-01-13, version 2.0.0*

記録もできない。30キロ離れた家の監視カメラ用にと導入したけど無意味でした。

### 5/5 — 面倒な設定が無く使いやすく

*2022-01-04, version 2.0.0*

設定が簡単です。
ペットの見守りに使わせて頂いています。
画角がもう少し広い方が良いと思います。
また、マイク🎤機能の復活を望みます。

### 3/5 — Ipadではフリーズがある。

*2021-09-18, version 2.0.0*

見守りモニターモードでサウンドのアイコンを押すとフリーズしてアプリが落ちます。
使用しているのはiPad air 4世代　です。

### 5/5 — とてもよいです。

*2020-10-24, version 2.0.0*

電源のないところで、1.5万円の太陽光パネル、3千円の軽のバッテリーとモバイルバッテリーとラインモバイルの月500円くらいのプランで運用しています。ひと月ほど経ちますが、ギガを使い切った後の低ビットレートでも動画で見られるのでとてもありがたいです。

ちょー欲をいうと、24時間動画保存といった機能が付く、または何かと連携ができたら月500円払っても良いです。

### 1/5 — 全くダメ。

*2020-10-10, version 2.0.0*

4時間ほど頑張りましたが、諦めました。何が悪いのか、さっぱりわかりません。使い方や設定の仕方を探しましたが、どこにも載ってませんでした。アプリが悪いのではなく、自分の接続環境が悪いのでしょう。

### 5/5 — 使い勝手がいい

*2020-10-10, version 2.0.0*

使い勝手がいいです！

### 1/5 — 最悪

*2020-06-02, version 2.0.0*

アプリが強制終了される

### 5/5 — 最高❗️

*2020-04-13, version 2.0.0*

とにかく最高❗️ちゃんと綺麗に写ります

### 4/5 — 2019.12   お試し中です。

*2019-12-27, version 2.0.0*

ややこしい設定もなく、シンプルに使えてます。
最初の設定時、IDは自分では決められないようなので何も入力せずに"ID作成"だけをタップして、後にパスワードを入力。その後、見るために使うスマホから同じことを入力して使用できました。
カメラはAndroidタブレット、見るのはiphoneで使えてます。iPad × iphoneでも使えました。

音声に関しては聞くことができても会話はできないので少し残念。また２ヶ所以上に設置してモニターするためにはいちいちIDを入力し直さないといけない？点も少し不便。

他アプリ同様、回線を利用して盗撮されている可能性も無いわけではないので、こちらは大丈夫なのか様子見中です。Appleのセキュリティをパスしてるから大丈夫だとは思いますので、あくまで念のためです(^^)

気持ち的には「無料でこれはすごい！」と☆５の素晴らしいアプリですが、じょうきのようにいくつか心残りなので今は☆４にしています。しばらく使用してみて後々、バッテリー消費なども含めてレビュー修正させて頂きたいと考えてます。

## Version history (last 5 releases)

### 2.0.0 — 2018-01-09

This app has been updated by Apple to display the Apple Watch app icon.

I changed the layout of the top screen.
Because it changed to a new SDK, it can not connect with past applications.
I set it to save mode automatically after the lost frame for 5 minutes.
We deleted the microphone function being monitored once. (We will return if there are many requests)

### 1.2.1 — 2017-07-03

Corrected to make judgment as soon as possible when connection was possible when selecting from the list at the time of monitoring.
Improve recontinuous processing at mimamori.

### 1.2.0 — 2017-05-05

I changed the design of the image display part.
Speaker function addition
· By pressing the speaker button on the monitor screen, you can listen to the sound in the forearm.
· Please note howling if you try near Mimamori terminal.
· You can stop the sound by pressing the speaker button again.
Addition of microphone function
· By pressing the microphone button on the monitor screen, it is possible to deliver the voice of the monitor side to the intruder side.
· Please note howling if you try near Mimamori terminal.
· Speaker sound temporarily stops when speaking with microphone while speaker function is on.
· You can stop the sound by pressing the microphone button again.

In the case of terminals with low specifications such as iPhone 4S, if you forcibly move the forehead screen, etc., the application may fall due to insufficient memory.
I'd like to correspond somewhat, but I have not been able to respond yet.

### 1.1.1 — 2017-03-27

Improve reconnection process.
# Cameras in the sunlight are checked at 5 minute intervals.
# If the app disappears from the list of monitors in the absence of falling, it will restore in 5 minutes.

### 1.1.0 — 2017-03-09

· Improve energy saving mode to further save energy
· Improved security

In order to improve the stability of iPhone 4S, in the case of iPhone 4S, I tried to lower the image quality and deliver it.
If you do not mind, please review.
