Installation – Sentry

Installation Requirements:

To install your Bosma Sentry video doorbell, please make sure that:

1. You have an existing doorbell wiring powered by a doorbell transformer or a DC 5V2A micro USB power source.
2. The doorbell transformer’s output is AC 8-24V (or 16-24V if a chime is installed), and at least 30VA of power. Insufficient power may result in frequent disconnection.
3. Your Sentry doorbell’s location has strong 2.4Ghz Wi-Fi coverage (5Ghz Wi-Fi is not supported) with a minimum of 2Mbps upload speed. Also, make sure that the Wi-Fi’s encryption method is either WPA or WPA2.
4. The camera’s lens is not exposed to direct sunlight.

Safety Reminder:

1. It is highly recommended to switch off power to your doorbell prior to installation. You can switch off the power by turning off the circuit breaker for your doorbell.
2. If you have an existing doorbell chime installed, you would need to go to Sentry settings -> Doorbell Chime and enable the option in the Bosma app after setting up Sentry, so that the chime still rings when Sentry’s doorbell button is pressed.

Warning: If Sentry is not connected to a chime (e.g. you’re connecting Sentry directly to a Low Voltage Transformer), please do NOT enable the “Doorbell Chime” option in-app. Enabling the “Doorbell Chime” option without an installed chime may pose a serious fire risk when Sentry’s doorbell button is pressed.

1. **Remove the base plate
   ** Slide down to remove the base plate from the doorbell.
   

2. Install a micro SO card
   If you want to install a micro SD card, please push back to remove the PIR module, insert a micro SD card into the SD card slot, and then replace the PIR module. Sentry supports a micro SD card up to 12868. Please make sure that the SD card is formatted to FAT32.
   Sentry requires either a micro SD card (local storage) or a Bosma Assist subscription (cloud storage) to store video recordings. If you intend to use local storage, it is recommended to install a micro SD card prior to installing Sentry, as installing the micro SD card requires uninstalling Sentry from the base plate.

3. Stick the installation sticker on the wall
   Remove the existing doorbell (if you have one) and leave the wires on the wall. It is recommended to switch off the power to the doorbell wires.
   Stick the installation sticker on the wall so that the wires go through the center hole on the sticker.
   *use a pen to mark the 4 spots on the wall
   If your wall has an uneven surface and the sticker won’t hold, you can also use a pen to mark the 4 spots on the wall.

4. Drill holes
   Use the provided drill bit to drill 4 holes at the marked spots on the sticker. Remove the sticker after finishing.

5. Insert the plastic anchors
   Put the plastic anchors into the 4 holes. If necessary, use a hammer to gently tap them in until they are flush with the wall.

6. Install the base plate Place

10. Secure the adapter cords
    Attach each adapter cord to a screw, and tighten the screws to secure the cords. It doesn’t matter which cord is attached to which screw.
    

11. Prepare the tamperproof screw
    Drive the provided tamperproof screw slightly into the bottom screw hole on the Sentry doorbell. Please make sure the tip of the screw stays beneath the end of the screw hole.
