Claims (2)
- 建物外構の上の水平方向に所定の間隔を隔てて複数の検知部を設け、隣り合う検知部間で一方の検知部に送信器と受信器とを上下に位置するように設けると共に他方の検知部に一方の検知部とは上下位置が逆になるように送信器と受信器とを設け、一方の検知部の送信器と他方の検知部の受信器を、一方の検知部の受信器と他方の検知部の送信器とを対向させた防犯装置であって、送信器から対向する受信器に向けて送信信号を送信し、該送信信号を対向する受信器で受信する際には、侵入者無しと判定し、該送信信号を対向する受信器で受信せず、該送信信号を送信した送信器と同一の検知部の受信器でのみ受信する際に、侵入者有りと判定し、該送信信号を、該同一の検知部の受信器でのみ受信する時間が一定時間継続した場合には、一方の検知部と他方の検知部との間に障害物が存在していると判定し、障害物に反射された該送信信号を、該同一の検知部の受信器で受信し、その電圧レベルを検出して侵入者の侵入を判定する反射型に切り替えることを特徴とする防犯装置。
- 上下の送信器と受信器とを組み込んでユニット化して検知ユニットを形成し、建物外構の上の検知部を設ける位置に検知ユニットを天地逆に固定可能にしたことを特徴とする請求項1記載の防犯装置。
