設置する必要があるセキュリティカメラの数

これは、自分の所有地に CCTV セキュリティシステムの設置を計画し始めるときに、誰もが尋ねるよくある質問です。自宅には何台の防犯カメラが必要ですか?建物を安全に保つために推奨される防犯カメラの数は?家や会社を完全にカバーするには、何台の防犯カメラが必要ですか?

あなたの財産を監視下に置き、安全に保つこととは別に、予算のバランスをとることも必要です.防犯カメラが増えるということは、カバーされる領域が増えることを意味しますが、CCTV 監視プロジェクトの全体的なコストが増加することも意味します。防犯カメラの数、種類、解像度、カバーするエリアの間で常にバランスを取る必要があります。この記事では、CCTV セキュリティシステムに必要なセキュリティカメラの数を計算する方法について説明します。

家には何台の防犯カメラを設置すればよいですか?

物件に設置する必要がある防犯カメラの数に影響を与える要因は多数あります。これらの要因には、物件のサイズ、ドアの数、カメラの種類、レンズのサイズ、カメラが通常のカメラであるかパン/チルト/ズームカメラであるか、カメラの角度、配置などが含まれます。単純。必要なセキュリティカメラの数を計算するには、次の 2 つのことを自問してください。

取り上げてほしい最も重要な分野は?

取り上げてはいけない分野は?

以下で詳細を説明し、最後のセクションで実際の例を示します。詳細は、住宅/家庭または中小企業向けの CCTV セキュリティプロジェクトをカバーしています。

取り上げてほしい最も重要な分野は何ですか?

不動産の間取り図を見て、重要で脆弱であると考えるエリアを特定する必要があります。監視セキュリティシステムの要点は、セキュリティ境界を家の壁の外側に拡張することです。危険で予期しない侵入者が生活圏に侵入した場合に、アラートと通知を受け取る必要があります。その意味で、重要な領域は、貴重なものを保管する領域であり、侵入される可能性が高い領域として定義されます.

家の中でカバーする必要があり、重要なエリアは次のとおりです。

ドア。 これには、正面、背面、または側面の入り口が含まれます。
窓。窓が監視されるように防犯カメラを配置する必要があります。窓が壊れて誰かが入ってくる可能性があります。窓が小さすぎて人が入らない場合は、脆弱な点として無視できます。
ガレージのドア。 多くの場合、ガレージのドアは侵入者の侵入口となります。ガレージのドアの前だけでなく、ガレージの内部にも防犯カメラを設置する必要があります (ガレージのドアが開いたときに確認できるようにするため)。
駐車場。 ガレージ内ではなく、屋外のどこかに駐車する場合は、防犯カメラを自分の車 (通常は駐車する場所) に向ける必要があります。
その他の屋外の場所 これには、プールエリア、小屋、その他の価値があると思われる場所が含まれます。

ビジネスの場合、値ははるかに重要です。エントリーポイントはもちろんですが、取引スポットにも注意が必要です。上記のエリア (ドアと窓) とは別に、これらのエリアもカバーするには料金を支払う必要があります:

お金を保管する場所。 レジは、取引が行われる場所です。防犯カメラがあると、盗難のリスクが軽減されます。
商品を保管するエリア。 倉庫、保管場所、製品を保管する場所ならどこでも。商品が適切に取り扱われていることを確認し、盗難や損傷の可能性を減らす必要があります。
従業員が働く場所 This is very important because you can monitor the productivity level, reduce laziness, prevent policy violations such as not following safety procedures, prevent sexual harassment or provide evidence for any false claims.
Parking lots. You should have these areas covered in order to protect and provide evidence for on-premise car crashes, insurance fraud and parking lot robberies (or assaults).

What areas should I not cover?

There are many areas inside your house or your business that should not be covered by security cameras. Moreover in certain spots, it’s illegal to have a CCTV security camera installed.

You should not install a camera on the sides of the home if there’s no way to get inside. Let’s say one side of the home has no doors or windows, so no one can break-in from there. In this case, you don’t need to install a security camera. Or you can install a fake camera on that side, just to scare people off.

Most of the homeowners don’t install security cameras inside their homes. The aim of a CCTV security system is to extend the security perimeter outside the walls of the house, so it’s a waste of resources to install security cameras inside the house. Moreover many family members don’t feel comfortable having cameras inside, it’s considered a very private space.

However, if you have in-home activity such as housekeepers, caregivers, nannies or medical aides, you may need to install security cameras indoors to keep them in check or to prevent any abuse. If you’re worried about something, you can install cameras inside to have a peace of mind.

Be aware that installing security cameras in a place where people have an expectation of privacy can be illegal and result in fines or in a lawsuit. Under no circumstances, should you use security cameras to monitor a bathroom or to record areas where you expect sexual activities to occur. Most of the time it is legal to monitor the bedrooms of people in your legal care who have advanced health risks (for example an elderly parent who has advanced medical needs), but you probably need their consent. It’s better to talk with a lawyer to clarify things up.

In a business setting, there’s not a lot of areas that can and should be omitted. You should cover most of the areas and have everything has to be monitored. Companies can be liable for almost everything that happens on their property, use CCTV security cameras to reduce your risks.

Do not install security cameras in a place where employees or customers have an expectation of privacy. For example installing security cameras in a bathroom or a fitting room is illegal. You should not install them in areas where you will conduct confidential meetings. If you’re not sure, we recommend to talk with a lawyer because the laws on each state or country are different.

An example:How many CCTV cameras do I need to install in my house?

Take a look at the picture below, it’s a regular house that illustrated the number of CCTV security cameras needed to extend your security perimeter and monitor the most important areas. To make things more understandable, we have illustrated a house from a bird’s-eye view.

As you can see in the illustration, this house needs 6 security cameras to cover all the areas around it. More details below:

Camera 1: It covers the north side of the house and overviews the main street. The front door and the windows on this side of the house are under surveillance.
Camera 2: This camera has a specific purpose, it monitors the porch on the main door and is dedicated only to the front door. All the packages and other details are under surveillance. If anyone comes through the front door, you will able to completely ID them.
Camera 3: This one covers the west side of the house, which is in this case corresponds with the parking spot when the homeowner parks his car. The car is fully monitored, along with the windows on this side of the house.
Camera 4: Monitors the left-center of the south side of the house and the backyard. The back door is located in this side of the house and numerous windows as well.
Camera 5: Monitors the right-center of the south side of the house and the backyard. The placement is in opposite of camera 4.
Camera 6: It covers the east side of the house, just the bathroom’s windows is located here. If that window was secured you may not need to install this camera. In this design, we think it’s better to have a camera here.

This is just an example, every house is specific, in this case we need 6 security cameras to extend the security perimeter of the house. Generally speaking, a house of this size and similar layout may need 6-8 cameras to have all the vulnerable and important areas covered.

What CCTV security system to buy?

There are many CCTV packages sold on Amazon that offer decent quality (HD) at an affordable price. Usually they come into packages of 4 or 8 security cameras. You can buy one of these CCTV security systems and install as many cameras as you need. Their apps allow you to view the cameras on the phone remotely, playback or get instant alerts. The cheapest ones are high resolution CCTV HD-over-coax cameras or you can even go for an IP security system (which is more expensive).
