藍牙追蹤_如何使用藍牙追蹤器跟蹤您的東西

藍牙追蹤

We’ve all done it: you misplace something important and you spend a lot of time (with a lot of stress) backtracking to locate it again. With Bluetooth tracking devices you can make the hunt a lot easier, less stressful, and even avoid losing the thing in the first place. Read on as we highlight the pros and cons of Bluetooth trackers.

我們都做到了：您將重要的東西放錯了位置，并且花了很多時間(承受很大的壓力)回溯以重新定位它。借助藍牙跟蹤設備，您可以使狩獵更加輕松，減輕壓力，甚至可以避免丟東西。在我們重點介紹藍牙跟蹤器的優缺點時，請繼續閱讀。

什么是藍牙追蹤器以及它們如何工作？ (What Are Bluetooth Trackers and How Do They Work?)

Bluetooth trackers are a relatively new product and the concept of them is just beginning to take hold in the consumer conscious. Before we dive into comparing features and products let’s take a moment to go over the general concept, what Bluetooth trackers are and, importantly, what they are not.

藍牙跟蹤器是一個相對較新的產品，它們的概念才剛剛開始在消費者意識中占據一席之地。在深入比較功能和產品之前，讓我們花點時間討論一下通用概念，什么是藍牙跟蹤器以及重要的是，什么不是。

什么是藍牙追蹤器？ (What are Bluetooth Trackers?)

The rise of Bluetooth Low Energy (known as BLE or Bluetooth 4.0)?really opened up the door to what could be done with Bluetooth devices.

藍牙低功耗技術(稱為BLE或藍牙4.0)的興起確實為藍牙設備的實現打開了大門。

Now instead of just the old staples (like Bluetooth headsets, speakers, and computer peripherals) manufacturers can pack Bluetooth into tiny devices that can survive off a small battery for upwards of a year without a battery swap or recharge.

現在，制造商可以將藍牙包裝到微型設備中，而這些微型設備可以依靠小電池生存長達一年以上而無需更換電池或充電，而不僅僅是舊的常用設備(如藍牙耳機，揚聲器和計算機外圍設備)。

One of those applications is tiny Bluetooth trackers wherein you can attach small tags to your keys, purse, or insert them into gear containers, instrument cases, or other objects you wish to keep track of (and not be separated from). The tags are linked to your smartphone (and potentially to a tracking service hosted by the manufacturer) via BLE and form a radio-based link between you and your stuff.

這些應用程序之一是微型藍牙跟蹤器，您可以在其中將小標簽粘貼到鑰匙上，錢包上，或將它們插入齒輪箱，儀器箱或其他您想跟蹤(而不是與之分離)的物體中。這些標簽通過BLE鏈接到您的智能手機(并可能鏈接到制造商提供的跟蹤服務)，并在您和您的東西之間形成了基于無線電的鏈接。

它們如何工作？ (How Do They Work?)

Thanks to the BLE system the Bluetooth tracker can stay in near constant communication with your smartphone (which isn’t particularly taxing to either your phone battery life or the device’s battery thanks to how truly low energy the whole exchange is). Because the tracking devices stay in constant communication with your phone then it’s easy for your phone (when paired with the appropriate software from the tracker vendor) to sound the alarm when you become separated from tracker and the object it’s attached to.

得益于BLE系統，藍牙跟蹤器可以與智能手機保持近乎恒定的通信(由于整個交換的能量非常低，因此這對手機電池壽命或設備電池的負擔特別小)。由于跟蹤設備與您的手機保持持續通信，因此，當您與跟蹤器及其連接的對象分離時，電話(與跟蹤器供應商提供的相應軟件配對)很容易發出警報。

Based?on the particulars of specific Bluetooth tracker you purchased and the accompanying software, the devices can do everything from chirp when you need to locate them, alert you when you stray too far from the tracking tag, remind you where the tag was last seen, and even anonymously alert you if other users of the same tracking service are near your lost item.

根據您購買的特定藍牙跟蹤器的詳細信息以及隨附的軟件，設備可以執行所有操作，從需要from聲的chi聲，偏離跟蹤標簽太遠時提醒您，提醒您最后一次看到該標簽的位置，如果其他使用相同跟蹤服務的用戶在您丟失的物品附近，甚至會匿名提醒您。

他們不能做什么？ (What Can’t They Do?)

Before we proceed it’s important to highlight a very key detail (that is initially a little confusing to consumers). Bluetooth tracking devices?are not GPS devices. Again, let us reiterate that strongly to avoid any confusion about the matter: Bluetooth tracking devices are not GPS devices.

在我們繼續之前，重要的是要突出一個非常關鍵的細節(一開始會給消費者帶來一些困惑)。藍牙跟蹤設備不是GPS設備。再次，讓我們重申這一點，以免造成任何混淆：藍牙跟蹤設備不是GPS設備。

Let’s use a hypothetical situation involving a camera bag and both a Bluetooth tracker and a GPS tracker to highlight the differences.

讓我們使用一個假設的情況，其中涉及一個相機包以及一個藍牙跟蹤器和一個GPS跟蹤器，以突出顯示它們之間的差異。

Scenario A: You have a GPS tracking device tucked in a small inner pocket inside your camera bag. The pricey GPS unit includes both geospatial tracking via the GPS satellite system as well as a modest cellular radio so that it can phone home to the manufacturer and tell you where your camera bag is.

方案A：您將GPS跟蹤設備塞在相機包內的小內袋中。昂貴的GPS裝置既包括通過GPS衛星系統進行的地理空間跟蹤，也包括適度的蜂窩無線電，因此它可以打電話給制造商，并告訴您相機包在哪里。

You leave the camera bag at a restaurant. As soon as you realize your bag is no longer at your side you whip out your smartphone and fire up the tracking app. Not only does the tracking app tell you if the bag is still at the restaurant?but if anyone picks up your bag and walks off with it as long as the GPS tracker has battery life left (and the person with your bag doesn’t find and remove it) you can get real time tracking results indicating where your bag is at the present moment and not just where it was last with you.

您將相機包留在餐廳。一旦意識到您的行李不再在您身邊，您就甩開智能手機并啟動跟蹤應用程序。跟蹤應用程序不僅會告訴您行李是否仍在餐廳，而且只要GPS追蹤器的電池壽命還剩下(如果沒有找到您的行李的人)，是否有人撿起您的行李并帶著它走下車刪除它)，您可以獲得實時跟蹤結果，該結果表明您的包目前在哪里，而不僅僅是最后一次出現在哪里。

Scenario B: You have a Bluetooth tracking device tucked in the same camera bag and you leave it in the same restaurant. You leave the restaurant and then realize you no longer have your camera bag. You whip out your smartphone and fire up the tracking app.

方案B：您將Bluetooth跟蹤設備塞在同一相機包中，然后將其留在同一家餐廳中。您離開餐廳，然后意識到您不再擁有相機包。您撥動智能手機并啟動跟蹤應用程序。

The tracking app tell you the last place it had access to the tracking tag (the restaurant) but it cannot tell you if the bag is still there or not (and it cannot track the bag if it has left the restaurant). If you return to the location you last saw your camera bag and it is still in that location then the Bluetooth tracker will reconnect with the device when you get close and show you where it is. (Hopefully safe in the manager’s office!) If the bag is gone, however, there’s nothing the Bluetooth tracker or the companion app can do because the entire affair is proximity-based.

跟蹤應用程序告訴您可以訪問跟蹤標簽的最后一個位置(餐廳)，但無法告知您行李是否仍在其中(如果行李離開餐廳，則無法跟蹤行李)。如果返回到您最后一次看到相機包的位置，但它仍在該位置，則當您靠近時，Bluetooth追蹤器將與設備重新連接并向您顯示它在哪里。 (希望在經理辦公室很安全！)但是，如果行李沒了，那么藍牙跟蹤器或配套應用程序將無法執行任何操作，因為整個過程都是基于鄰近性的。

是藍牙追蹤器嗎？ (Is A Bluetooth Tracker For Me?)

Based on the aforementioned scenarios you can get a good sense of whether or not a Bluetooth tracker is for you. If you frequently misplace your keys and you need to remember where they are (like sitting on the bar at your favorite pub) or find them lost in your office (most Bluetooth tags can make noise to help you locate an object when you’re close to it), then a Bluetooth tracker is a really high tech and practical solution to your lost-object woes. It’s also an excellent fit for when you’re carrying something you don’t normally carry (like an extra bag for work) that you might be prone to forgetting somewhere because it isn’t part of your normal daily routine.

根據上述情況，您可以很好地了解藍牙跟蹤器是否適合您。如果您經常放錯鑰匙，并且需要記住它們的位置(例如坐在您最喜歡的酒吧的酒吧上)或發現它們丟失在辦公室中(大多數藍牙標簽會發出噪音，以幫助您在關閉時找到對象)，那么藍牙跟蹤器是一種真正高科技的實用解決方案，可以解決丟失的物品的麻煩。當您攜帶通常不攜帶的東西(例如一個額外的工作袋)時，由于不屬于日常工作的一部分，您可能容易忘記該地方，它也非常適合。

If you want to secure an object, however, and have the ability to track that object if it is stolen then a Bluetooth tracker is not powerful or far reaching enough for your needs. It’s perfect for finding lost keys and the laptop bag you always misplace at corporate headquarters but it’s not an effective solution for monitoring a bag with $10,000 worth of camera equipment in it.

但是，如果您想保護一個對象，并且能夠跟蹤該對象是否被盜，則藍牙跟蹤器功能不強大或無法滿足您的需求。它非常適合查找丟失的鑰匙和您在公司總部經常放錯的筆記本電腦包，但對于監視其中裝有價值10,000美元的攝像設備的包來說，這不是一個有效的解決方案。

Again, for emphasis, Bluetooth trackers are like really fancy high-tech reminders of where your stuff was, can offer alerts if your stuff is currently leaving your vicinity, and they can help you find a lost object in your immediate environment (both by audible alerts and proximity location) but they are not a substitute for the much more expensive and expansive real-time tracking offered by GPS units if you need to keep an eye on expensive gear wherever it may end up.

再次強調一下，藍牙跟蹤器就像真正的高科技提醒一樣，可以提醒您物品所在的位置，可以在您的物品當前正在離開附近時發出警報，并且可以幫助您在附近的環境中找到丟失的物體(兩者都可以聽到)警報和鄰近位置)，但如果您需要隨時隨地關注昂貴的設備，則它們不能代替GPS單元提供的更昂貴，更廣泛的實時跟蹤。

要考慮的功能 (Features to Consider)

Now that we’ve talked about exactly what a Bluetooth tracker is, what it isn’t, and why you might want one, let’s take a look at the features found in Bluetooth trackers. Given the influx of these devices it’s important to have a clear picture of which features you need.?Not everyone will want or need all of these features, but it’s better to know what you don’t need than to make an uninformed purchase.

既然我們已經確切地討論了什么是藍牙跟蹤器，什么不是藍牙跟蹤器以及為什么要購買藍牙跟蹤器，所以讓我們看一下藍牙跟蹤器中的功能。考慮到這些設備的大量涌入，重要的是要清楚了解所需的功能。并非每個人都會想要或需要所有這些功能，但是最好知道自己不需要什么，而不是進行不知情的購買。

電池用戶可以更換嗎？ (Is The Battery User Replaceable?)

We’d consider this the highest priority (barring it getting overruled by an absolute-must-have-feature on a device without a user-replaceable battery). Bluetooth trackers run $20-50 or so and the batteries generally last about a year.

我們認為這是最高優先級(除非在沒有用戶可更換電池的設備上，它被絕對必要的功能所推翻)。藍牙追蹤器的價格為20至50美元左右，電池一般可以使用一年左右。

If you can’t replace the battery then you’re stuck buying a new one every time the battery runs out. Considering coin cell batteries cost less than a dollar replacing a whole tracker for $20+ is a tough pill to swallow. Can you replace it? Recharge it?

如果您無法更換電池，那么每次電池用完時，您就不得不購買新電池。考慮到幣形電池的成本不到一美元，而以20美元以上的價格替換整個追蹤器，這是一個令人費解的藥。你能代替它嗎？充電嗎？

警報有多響？ (How Loud Is The Alarm?)

A frequent complaint among consumer reviews of Bluetooth trackers is that the volume of the little speakers included in them is too low. Even if you don’t plan on relying on audio cues they’re important as the closer you are to the Bluetooth tracker the more difficult it becomes to exactly pinpoint the object (especially if it is small like a set of missing keys). A loud chirp or jingle when you’re right on top of it (but having no luck locating it) is very useful.

消費者對藍牙跟蹤器的評論中經常抱怨的是，其中包含的小揚聲器的音量太低。即使您不打算依賴音頻提示，它們也很重要，因為您離藍牙跟蹤器越近，精確定位對象就越困難(特別是如果它像一組缺少的鍵一樣小)。當您正好在其上時發出響亮的chi聲或叮當聲(但找不到運氣)非常有用。

什么是廣告范圍？ (What Is The Advertised Range?)

There is no inherent limitation built into the Bluetooth protocol and, according to the Bluetooth consortium, Bluetooth devices can be optimized for 200 feet and beyond. That said radio signals are radio signals and both the limitations of crafting a tiny transmitter (and keeping it powered for a year) as well as environmental variables have a significant impact on real world use.

藍牙協議沒有內置的限制，根據藍牙聯盟的說法，藍牙設備可以優化200英尺及以上的距離。那就是說無線電信號就是無線電信號，制造微型發射機(并將其保持一年供電)的局限性以及環境變量都對現實世界的使用產生了重大影響。

A good rule of thumb is to assume you’ll get 50-70 percent of the range advertised by the manufacturer. If they say you’ll get 150 feet, plan on getting 75. If they say you’ll get 100 feet, plan on 50.

一個好的經驗法則是假設您將獲得制造商廣告范圍的50％至70％。如果他們說您將得到150英尺，則計劃增加75英尺。如果他們說您將得到100英尺，則計劃增加50英尺。

該軟件是否支持地理圍欄？ (Does The Software Support Geofencing?)

Knowing where your keys were last seen is great and all but what about getting an alert right at the moment you stroll away from them?

知道您的鑰匙最后一次出現在哪里很重要，除了在您離開鑰匙時立即獲得警報該怎么辦？

This is where geofencing capabilities come in. A geofence is simply a virtual boundary around something created using radio frequency and/or GPS. If you an alert on your smartphone when you get too far from your secured object (or you would like an alert when it gets too far from you!) then you need a Bluetooth tracker with software support for geofencing.

這就是地理圍欄功能的用處。地理圍欄只是使用射頻和/或GPS創建的物體周圍的虛擬邊界。如果您在距離安全對象太遠的情況下在智能手機上發出警報(或者，當您離安全對象太遠時希望發出警報！)，則需要具有地理圍欄軟件支持的Bluetooth跟蹤器。

Companies use different terms like geofencing, proximity alerts, or leashing, but the basic premise is the same: you’ll get a push notification when you forget your stuff.

公司使用不同的術語，例如地理圍欄，鄰近警報或牽引，但基本前提是相同的：忘記了內容就會收到推送通知。

它可以找到您的手機或執行其他功能嗎？ (Can It Find Your Phone Or Perform Other Functions?)

While the majority of Bluetooth tracking devices are one trick ponies (and who can blame them when they’re to last a year on a single battery) there are what we would call “bonus” features on some current generation models.

盡管大多數藍牙跟蹤設備只是一個小玩意兒(誰能責備它們僅用一個電池就可以使用一年)，但在某些當前型號上，我們稱之為“獎勵”功能。

One of those useful features is the ability to, in reverse and rather ironically, find your lost phone. Some Bluetooth trackers have a button you can press and hold to reverse the whole location process so when you have your keys (but not your smartphone) you can sound an alert on your phone to use the same find-by-ear process in reverse to locate your lost smartphone.

這些有用的功能之一是反過來(很諷刺地)找到丟失的手機的功能。某些藍牙跟蹤器具有一個按鈕，您可以按住該按鈕以逆轉整個定位過程，因此，當您擁有按鍵(而不是智能手機)時，可以在手機上發出警報，以使用相同的按耳旁聽過程進行反向操作。找到丟失的智能手機。

它支持眾包位置嗎？ (Does It Support Crowdsourced Location?)

We’ll be honest with you. Unless you live in New York City this feature is next to useless but we’ll highlight it here just so you’re aware of it and what it does. The premise is that when you lose your tagged object (your keys, your duffle bag, etc.) you use the companion software on your phone to flag the bluetooth tracker as lost. Then when another user of the same software/bluetooth tracker passes by and picks up the signal from your device you’ll get a status update based on the new location of the tracker.

我們將對您誠實。除非您居住在紐約市，否則此功能幾乎是無用的，但我們將在此處突出顯示此功能，以便您了解它及其功能。前提是當丟失標有標簽的對象(您的鑰匙，行李袋等)時，可以使用手機上的配套軟件將藍牙跟蹤器標記為丟失。然后，當同一軟件/藍牙跟蹤器的另一個用戶經過并從您的設備接收信號時，您將根據跟蹤器的新位置獲得狀態更新。

That’s great in premise but in practice let’s be real. What are the chances that?another person in your general geographic location is also using the exact same tracker and software (let alone a tracker at all) and that they’ll also not just be using the software but that they’ll pass by your lost object (with the tracker still attached) within 30-100 feet and remain there long enough for the tracker to ping their phone and update you with the location status? Nearly zero.

前提是很棒，但實際上我們是真實的。您的一般地理位置中的另一個人也有可能使用完全相同的跟蹤器和軟件(更不用說跟蹤器了)，而且他們不僅將使用該軟件，而且還會繞過您的丟失者在30-100英尺內的物體(仍連接了跟蹤器)并保持足夠長的時間，以便跟蹤器ping他們的電話并向您更新位置狀態？幾乎為零。

推薦型號 (Recommended Models)

Now that we’ve talked about what Bluetooth trackers are and what kind of features to look for, let’s take a look at the models we’ve field tested and what our recommendations are. One thing we’d like to get out of the way right from the start is that we weren’t 100 percent happy with?any of the models we tested.

既然我們已經討論了什么是藍牙跟蹤器以及要尋找什么樣的功能，那么讓我們看一下我們經過現場測試的模型以及我們的建議。我們希望從一開始就擺脫困境的一件事是，我們對所測試的任何模型都不是100％滿意。

The Bluetooth tracking market is still under significant development and as of the publication date of this article there isn’t a single device on the market that gets a high score in all of the categories we outlined in the previous section.

藍牙跟蹤市場仍處于顯著發展中，截至本文發布之日，市場上還沒有哪一種設備在上一節概述的所有類別中均獲得高分。

That said, there are devices that excel in each of the categories and when shopping you should focus on selecting a device that does the one or two must-have-features on your list very well instead of trying to find (or waiting for years for) a device that does it all.

就是說，有些設備在每個類別中都有出色的表現，購物時，您應該專注于選擇一種能夠很好地滿足列表中一個或兩個必備功能的設備，而不是試圖尋找(或等待數年) )可以完成所有操作的設備。

So which models did we field test and review? The leading Bluetooth tracker on the market as it was both first to market, created through a widely promoted crowdfunded campaign, and by far the best selling, is the Tile tracker. Because we hate to go with the best selling solution without testing the waters (and potentially saving you time and money in the process) we also purchased the Duet tracker and the iHere3 tracker, both popular and briskly selling models.

那么我們對哪些模型進行了測試和審查？ Tile跟蹤器是市場上領先的藍牙跟蹤器，它是通過廣泛宣傳的眾籌活動而首次推向市場的，也是迄今為止最暢銷的。因為我們討厭在沒有測試水位的情況下使用最暢銷的解決方案(并可能在此過程中節省您的時間和金錢)，所以我們還購買了Duet追蹤器和iHere3追蹤器，它們都是流行的和暢銷的型號。

Let’s take a look at what worked, what didn’t work, and what frustrated us about each of the models.

讓我們看一下什么有效，什么無效以及什么使我們對每個模型感到沮喪。

瓷磚 (The Tile)

We’ll be upfront with you. We wanted to dislike the Tile. We didn’t like how spartan the feature set was. We didn’t like that the battery was not rechargeable or user-replaceable. We thought the software could include more features.

我們將與您取得聯系。我們想討厭瓷磚。我們不喜歡該功能集的簡單程度。我們不喜歡電池不能充電或不能用戶更換。我們認為該軟件可能包含更多功能。

But despite our reservations about the Tile there there’s a reason it is a bestseller and why it has 4/5 stars with 2,000+ ratings on Amazon. It works. It might not be flashy. It might not have advanced features. But frankly if your choices in the market are “not a lot of features but consistent stable performance” or “doesn’t work at all”, we guess the choice is pretty clear, no?

但是，盡管我們對Tile持保留態度，但有一個理由使它成為暢銷書，以及為什么它在亞馬遜上擁有4/5顆星并獲得2,000+評分。有用。它可能不會浮華。它可能沒有高級功能。但是坦率地說，如果您在市場上的選擇是“功能不多，但穩定的性能仍然穩定”或“根本不起作用”，我們認為選擇很明確，不是嗎？

It’s extremely small, barely bigger than the coin cell battery inside it. While it doesn’t appear to have a button there is a tiny button hidden under the “e” in the “tile” logo on the front of it. Pairing the Tile is very easy. You install the app. You press the “e” button for a few seconds. It chirps a little song at you. That’s it. No fiddling, no resetting the unit, no pairing and unpairing. It works. Period.

它非常小，幾乎不比其內部的紐扣電池大。盡管它似乎沒有按鈕，但是在它前面的“ tile”徽標中的“ e”下方隱藏著一個小按鈕。配對圖塊非常容易。您安裝該應用程序。您按下“ e”按鈕幾秒鐘。它向您鳴叫一聲。而已。無需擺弄，無需重置設備，無需配對和取消配對。有用。期。

On the downside, there are a lot of cool features that the Tile lacks. It doesn’t do geofencing. You can’t set up “home” zones where the device won’t alert you if you get separated from your keys (e.g. it won’t sound the alarm if you leave your keys in the kitchen and walk to the backyard).

不利的一面是，Tile缺少許多很酷的功能。它不做地理圍欄。您無法設置“家”區域，如果您與鑰匙分開，設備將不會向您發出警報(例如，如果您將鑰匙放在廚房里并走到后院，它將不會發出警報聲)。

But, like we said, it works consistently and in the entire sequence of tests we conducted the Tile never faltered once. We never had to reset or repair it. We never got frustrated that it didn’t work. It tells you where it last was. It has a locator function to help you find the Tile once you’re physically close to it. It has an audible alarm. You can mark a Tile as completely lost and if other Tile users come near it you’ll get an anonymous and updated location.

但是，就像我們說的那樣，它始終如一地工作，并且在進行測試的整個過程中，Tile從未動搖過。我們從來不需要重置或修復它。我們從來沒有為它的失敗而沮喪。它告訴您最后的位置。它具有定位器功能，可幫助您在物理上靠近圖塊時找到它。它有聲音警報。您可以將圖塊標記為完全丟失，如果其他圖塊用戶走近它，您將獲得一個匿名的更新位置。

The alarm isn’t very loud but instead of simple beeping sound it plays a shrill little tune. Despite the fact that the Tile wasn’t the loudest we swear the different tons of the tune made it easier to locate it when searching via audio feedback.

警報不是很大，但是它發出的是尖利的微調，而不是簡單的蜂鳴聲。盡管Tile不是最響亮的事實，但我們發誓不同噸的音樂使通過音頻反饋進行搜索時更容易找到它。

Our biggest complaint about the Tile isn’t the lack of features or the not-super-loud alarm, it’s that the battery isn’t rechargeable or user-replaceable and the Tile costs $25. The company behind the Tile says they’re working on a plan to replace Tiles for existing customers at a discounted rate but as of right now that plan isn’t in place which means every Tile has a shelf life and a replacement cost of $25.

我們對Tile的最大抱怨不是缺乏功能或非響亮的警報，而是電池無法充電或用戶無法更換，而Tile的價格為25美元。 Tile背后的公司表示，他們正在制定以折扣價為現有客戶更換Tiles的計劃，但是截至目前，該計劃尚未到位，這意味著每個Tile都有保質期，更換成本為25美元。

二重唱 (The Duet)

The Duet has a much broader feature set than the Tile but it was a bit frustrating to set up. While the Tile paired immediately and without hiccup to both our iPhone and our Android phone, the Duet refused to pair properly with our iPhone (although it paired fine with the Android phone right out of the gate).

Duet具有比Tile更為廣泛的功能集，但設置起來有些令人沮喪。雖然Tile可以立即與我們的iPhone和Android手機配對且沒有打擾，但Duet拒絕與我們的iPhone正確配對(盡管它與Android手機配對很好)。

In fact we were positive the Duet was a defective product simply because it wouldn’t work for more than two seconds at at time and multiple reviewers on Amazon reported the exact same lackluster experience. Only after we restarted our iPhone and repaired the device did it work as advertised. Given that people rarely restart their smartphones we can see how that little quirk led to so many negative reviews as people presumed the device was defective.

實際上，我們肯定Duet是有缺陷的產品，僅僅是因為它一次不能運行超過兩秒鐘，并且亞馬遜上的多個審閱者報告了完全一樣的乏味體驗。只有在重新啟動iPhone并修復設備后，它才能像廣告中所述的那樣工作。鑒于人們很少重啟智能手機，我們可以看到這個小怪癖如何導致許多負面評價，因為人們認為該設備存在缺陷。

On the positive side of things, once we did jump through that irritating hoop the device functioned as promised and it has a pretty robust feature set. In addition to the very basic “Where is my device?” function the Duet really shines with two additional useful functions. First, you can press the button on the Duet to find your phone. Given that we more frequently misplace our phone than we misplace our car keys it’s really useful to click the little button and have your phone immediately start announcing its presence.

從積極的方面來看，一旦我們確實跳過了令人討厭的問題，該設備就會按預期運行，并且具有相當強大的功能集。除了非常基本的“我的設備在哪里？”之外功能Duet確實具有兩個附加的有用功能。首先，您可以按Duet上的按鈕找到您的手機。由于我們放錯電話的頻率比放錯車鑰匙的頻率高，因此單擊小按鈕并讓您的電話立即開始宣布它的存在非常有用。

The second very useful feature is the ability to set safe zones via Wi-Fi addresses. Let’s say you don’t want the Duet to sound the alarm if you are separated from your tracker while you’re at home or at work (but you still want the alarm to work everywhere else). You can add the Wi-Fi networks at home and work to the safe list so while your phone is connected to those networks it will not alert you if you are separated from the device.

第二個非常有用的功能是可以通過Wi-Fi地址設置安全區域的功能。假設您不希望二重奏在家里或工作中與跟蹤器分開時發出警報(但您仍然希望警報在其他任何地方都可以使用)。您可以在家中添加Wi-Fi網絡并將其添加到安全列表中，因此，當您的手機連接到這些網絡時，如果您與設備分開，則不會提醒您。

Like the Tile it will show you the last location of the tagged device, it has a locator function to help you find the device when you are physically close to it, it also has a report-as-lost function, and you can press a button in the phone app to make the device beep. The beep is fairly soft and monotone but serviceable.?Unlike the Tile you can replace the battery with a simple coin cell battery.?The Duet retails for $30.

像圖塊一樣，它會向您顯示被標記設備的最后位置，它具有定位器功能以幫助您在物理上靠近該設備時找到該設備，它還具有報告丟失的功能，您可以按手機應用程序中的按鈕以使設備發出嗶嗶聲。蜂鳴聲相當柔和，單調但可以使用。與Tile不同，您可以使用簡單的紐扣電池更換電池。 Duet的零售價為30美元。

iHere3 (The iHere3)

The iHere3 also suffered from the “What iPhone?” syndrome that the Duet initially suffered from. Until we rebooted our iPhone it refused to pair properly; it paired fine with our Android test phone.

iHere3也遭受了“什么iPhone？”的困擾。二重奏最初遭受的綜合癥。在我們重新啟動iPhone之前，它拒絕正確配對。它可以與我們的Android測試手機搭配使用。

Size wise it?was the biggest tracker we tested and was, give or take, the same size as the Tile and the Duet stacked together (roughly the size of a small automotive key fob). The two features that set the iHere3 apart from the two previous devices are the multi-function button located in the center of the device and a rechargeable battery.

尺寸方面，它是我們測試過的最大的跟蹤器，大小與堆疊在一起的Tile和Duet相同(大約是小型汽車鑰匙扣的大小)。使iHere3與之前的兩個設備區分開的兩個功能是位于設備中央的多功能按鈕和可充電電池。

The large (and consciously iPhone 4-esque) button located in the center of the device can be used to perform a variety of functions as specified by the phone software. You can use it to find your phone (like the Duet’s button). You can use it to trigger a voice recorder (on the phone not on the actual tracker) or to trigger the phone’s camera (which makes it perfect for pairing with a camera tripod or selfie stick for snapshots).

位于設備中央的大按鈕(有意識地使用iPhone 4式按鈕)可用于執行電話軟件指定的各種功能。您可以使用它來找到您的手機(例如Duet的按鈕)。您可以使用它來觸發錄音機(在電話上而不是實際的跟蹤器上)或觸發電話的相機(這使其非常適合與相機三腳架或自拍桿配對拍攝快照)。

You can also use the “Car Finder” feature where clicking the button on the iHere3 saves your current GPS location and then later, when you can’t find your car, you can open the iHere3 phone app and it’ll point you back to your car with a simple directional arrow and indicator showing you how many feet away the car is. While you can find apps in the App Store to perform the same function, the one-click-on-your-key-chain trick with the iHere3 is really handy.

您還可以使用“汽車搜索器”功能，單擊iHere3上的按鈕可保存您當前的GPS位置，然后，當您找不到汽車時，可以打開iHere3手機應用程序，它將指向您您的汽車上有一個簡單的方向箭頭和指示器，可向您顯示汽車有幾英尺遠。雖然您可以在App Store中找到執行相同功能的應用程序，但iHere3的一鍵式鑰匙鏈技巧確實非常方便。

The iHere3 comes with a little USB cable that has a post-style terminal at the end you insert into the iHome3 to recharge it. The projected battery life is up to six months and it recharges completely in about an hour. The alarm sound on the iHere3 is, by far, the loudest of three trackers we tested and has a simple four-note rising chime. Even when under an object or in a bag the alarm was loud enough to be heard.?The iHere3 retails for $25.

iHere3帶有一條USB電纜，在插入iHome3進行充電時，該電纜的末端有一個后置式端子。預計電池壽命最長為六個月，大約一個小時即可充滿電。到目前為止，iHere3上的警報聲音是我們測試的三個追蹤器中聲音最大的，并且具有簡單的四音高音。即使在物體下方或在袋子中時，警報也足夠響亮以至于無法聽到。 iHere3的零售價為25美元。

Bluetooth trackers are still in their infancy but the potential for such simple and low-power devices is great. If you’re looking for a foolproof and low-fuss solution, we recommend the Tile. If you’re looking for rich features, we recommend you look elsewhere and either wait for the market to mature or take the good and bad of less polished products like the Duet.

藍牙跟蹤器仍處于起步階段，但這種簡單，低功耗設備的潛力很大。如果您正在尋找一種萬無一失的解決方案，我們建議您使用Tile。如果您正在尋找功能豐富的產品，我們建議您將其放在其他地方，或者等待市場成熟，或者采用諸如Duet之類的打磨程度較低的產品的優缺點。
