Sentry: The Most Advanced Doorbell

Never miss a visitor

Get instantly notified when someone rings your doorbell. See and talk to your guest from your phone like a video call with Real 2-way Audio.

Busy or missed the notification? No worries. Sentry can automatically play a prerecorded voice message to your guest, and have them leave a voice message to you too.

No more false alarms

Tired of seeing false motion alerts from drive-by cars, swaying twigs, moving shadows? Sentry uses Advanced Motion Detection to only capture motion of people, so you will only receive notifications that are relevant. 

Color Night Vision

Monitor your front door in vivid color and clarity, even at night.

You can also switch back to regular black-and-white night vision.

Local & Cloud Storage

The choice is yours! You can choose to store video clips on the cloud for up to 30 days(1), or store them locally with a micro SD card up to 128GB(2)… or both!

(1) Bosma Asisst subscription required

(2) Micro SD card sold separately

Advanced AI Security*

You should not need to constantly check alerts on your phone to see what’s going on. It’s 2020 already – let the AI do it for you.

* Bosma Assist subscription required

Facial Recognition

Always know whether it’s a stranger or a familiar person at the door with Sentry’s Facial Recognition.

Package Detection

When a package is delivered to your door, Sentry will automatically notify you, so you don’t need to worry about when your packages are delivered.

Active Theft Prevention

Sentry protects your packages when you’re away. When Sentry detects that someone is stealing your package, it can automatically sound its built-in 100dB siren to scare off the thief.
Why do I need Active Theft Prevention?

According to statistics, one in every four people have reported being a victim of package theft, and among the reported cases, a staggering 90% of them remain unsolved.

Many people install video doorbells to watch over their packages. However, most video doorbells only record the event and send you a notification when package theft happens. If you do not immediately respond to the notification, your package will be stolen anyway, and it’s unlikely that you will get it back even if you report the case with the recorded video.

Therefore, instead of being reactive and always requiring your attention, Sentry takes a more proactive approach to prevent package thefts. When Sentry detects that someone is stealing your package, it can automatically sound its built-in 100dB siren to scare off the thief. Sentry protects your packages when you’re away, so you don’t need to stay alert for package notifications anymore

Connectivity

Connect Sentry with Bosma Aegis smart lock and many other peripheral sensors to build a truly smart home.

Unlock your door with fingerprint*

Sentry can attach a fingerprint module that works with the BOSMA Aegis smart lock to enable fingerprint access to your door.

The fingerprint module also allows you to remotely unlock the door for your guests or family members and manage guest access.

* Sentry Fingerprint module required

Smart Hub

Sentry also integrates a hub that works with other Bosma peripheral sensors and lights, such as the Bosma door sensor that notifies you when a door or window in your home opens.

FAQs

The Sentry doorbell is wired. It requires existing 8-24V AC doorbell wiring.

Alternatively, it also supports 5V 2A DC power source via a micro USB port.

(1) Upper-quarter Flashing: Device reset/powering up

(2) Lower-quarter Flashing: Connected to WiFi and connecting to server

(3) Left-quarter Flashing: Voice message recording

(4) Right-quarter Flashing: Connecting to WiFi

(5) Full-circle Flashing: Updating firmware

With a few simple tools, you can certainly install Sentry yourself. You can follow the installation instruction in the box, as well as this installation video.

(1) Download the “Bosma” app, create a new account or log in.

(2) Make sure that Sentry is powered and that you have heard it say “system startup” and “waiting for connection”. If you don’t hear these messages, reset the camera.

(3) On the app home screen, tap the “+” button at the top right corner, and select “Sentry”. Then follow the in-app instructions to complete the setup

If you have any issue during the setup process, please contact customer support.

Please make sure that your Sentry is powered. Remove the base plate if it’s on. You should find a reset button with a “RESET” text to its left between the two terminal screws at the top of the camera body. Long-press the reset button until you hear “system reset”. After about 30 seconds, Sentry should power up again and you should hear “system startup” and “waiting for connection”. You can now set up Sentry in the app again.

Please make sure that you heard “system reset” after long-pressing the reset button, and that you heard “system startup” and “waiting for connection” later. If one of these messages was not heard, please contact customer support.

Note: If you intend to use Sentry’s local storage, it is recommended to insert an SD card prior to installing Sentry. 

Slide down to remove Sentry’s base plate, then push back to remove the PIR module on the top. You should now see the SD card slot on the top of the camera body. Push the SD card all the way in with its metal strips facing towards the back of the doorbell, until you hear that it clicks into place. To remove the SD card, push the SD card in again and it should be ejected from the slot. After inserting the SD card, replace the PIR module.

You can also watch the installation video to locate the SD card slot.

(1) Download the latest firmware here.

(2) Unzip the files and copy the files to the root folder of a micro SD card

(3) Disconnect Sentry from power and insert the micro SD card into Sentry (where is the SD card slot?). If Sentry was installed, you will need to unmount it from the base plate.

(4) Power up Sentry again (you can also use a 5V2A micro USB adapter to power it up). Immediately after Sentry is connected to power, long-press the RESET button at the back of the doorbell body for about 3 seconds. You should now see the doorbell indicator light flashing in full circle.

(4) Wait for about 2 minutes. When you hear “system startup” and “waiting for connection” at the end, the firmware update is successful.

(5) Please remember to unmount the SD card and delete the firmware update files before using it on Sentry again. Otherwise Sentry will enter firmware update every time it restarts

(1) On the QR code scan page, please have the camera scan the QR code on your phone. Make sure that you have heard the camera say “WiFi is connecting” before tapping the “I heard ‘Wi-Fi is connecting’” button

(2) Please make sure that the WiFi hotspot you selected is 2.4Ghz. 5Ghz WiFi is not supported.

(3) Please make sure that the WiFi hotspot uses WPA or WPA2 security

(4) Please double check and make sure that the password is correct

If the issue persist, please contact customer support

Yes. If your doorbell wiring is connected to an existing chime, you can enable doorbell chime support in Sentry Home -> Settings -> Doorbell Chime.

Warning: Before enabling the Doorbell Chime option, please make sure that a doorbell chime is properly installed. Enabling this option without an existing chime may damage the Sentry doorbell and/or your transformer and could pose a serious fire risk when Sentry’s doorbell button is pressed.

Yes. You can power Sentry with a 8-24V Low Voltage Transformer directly.

Warning: If you do not have a doorbell chime also connected to the transformer, please do NOT enable the Doorbell Chime option

Please first make sure that you have an active Bosma Assist subscription, and that you have added this Sentry device to the subscription

(1) You can find them in Sentry home page -> Cloud Videos

(2) You can also find them in Home page -> Bosma Assist ->  Cloud Videos

Yes. If your Sentry has a micro SD card, it’ll also save video recordings to the SD card, regardless of whether a cloud storage subscription is active.

Please first make sure that you have an active Bosma Assist subscription, and that you have added this Sentry device to the subscription.

After you successfully added familiar faces, please make sure Facial Recognition is enabled in Sentry Home -> Settings -> Event & Notification -> enable “Person”

There are two types of voice messages for Sentry.

(1) No Answer messages: Voice message played when you did not respond to a doorbell ring on the Bosma app in time (about 20s)

(2) Busy messages: Voice message played when you selected to “ignore” a doorbell ring on the Bosma app

 

You can manage voice message settings in Sentry home -> Voice Responses. To add a new voice response, tap the “+” button at the top right corner. To enable a voice message, enable the “Go to Voice Messages when busy/no one answers” option (if this option is disabled, visitors will not hear a voice message and cannot leave a voice message to you either).

 

There’s also an “Enable Voice Message” option on Sentry’s home page. If this option is enabled, when someone is ringing the doorbell, you will not receive a notification and Sentry will play the “Busy” voice message automatically. You can use this option when you do not wish to be disturbed.

Sentry Home -> Settings -> Event & Notification -> enable “Package”

  1. To use Package Detection and Active Theft Prevention, you must have an active Bosma Assist Pro subscription, and your Sentry doorbell must be added to the subscription
  2. The Sentry camera must have a clear view of the package. If the package is partially or fully blocked from the camera’s view, Sentry may not be able to detect it.

Theft prevention will not be triggered if the Sentry doorbell recognizes a familiar face. Please create a new face profile for yourself (and your family members if necessary) at Sentry Home -> Facial Recognition.

Short answer: you would need to install a resistor (recommended 10Ohm 0.5W) across the leads on your mechanical doorbell. See below for example:

Long explanation: It is not uncommon to hear the chime buzz after installing a video doorbell. The reason is that before you installed Sentry, the doorbell button acts as a switch for the electric circuit, so when the button is pressed, the circuit is closed and the chime rings. Sentry requires constant power so the circuit is always closed, and depending on the power consumption of the chime, there might be enough residual current in the circuit to cause the chime to buzz. Installing a resistor across the leads dissipates the current through the chime, thus reducing the buzzing.
