FAQs
Here are some of the frequently asked questions about this product
What happens if I buy a smart door lock and it doesn't work?
You can email us for a full refund or one of experts can try to find another model that works for you. See Refund policy for more information
How can I track my order?
Does the SDL-SA1 need a Wi-Fi Bridge?
No. The SDL-SA1 has Wi-Fi (2.4 Ghz) built directly into the lock, so it doesn't need a separate Wi-Fi Bridge to enable remote access, Amazon Alexa or Google Assistant.
Does face recognition work in the dark?
Yes. The SDL-SA1's 3D face recognition doesn't depend on ambient light, so it reads your face in complete darkness as well as it does in daylight — no porch light needed, and no fumbling for a phone or keys with your hands full. The video doorbell camera has night vision as well, so you can still see who is at the door after dark.
Can I manage authorised faces remotely?
Yes, for faces that are already enrolled. Enrolling a new face has to be done at the door, in person — and that is a privacy design, not a limitation. Your face data is stored inside the lock and never leaves the device; the app only ever holds a reference ID for each enrolled user. Once a face is enrolled, you can manage its access remotely from the app: enable it, disable it or delete it from anywhere. So if a housemate moves out or a cleaner finishes up, you can remove their access without being home.
What happens to the video doorbell if my Wi-Fi drops out?
The lock keeps working exactly as normal — face, fingerprint, code, card and mechanical key all run on the lock itself, not on your network, so nobody gets locked out. Wi-Fi only affects the remote features. When a visitor presses the doorbell icon on the keypad, the lock chimes at the door either way, so if you are home you will still hear it. Ringing your phone is the part that needs Wi-Fi, so if the connection is down at that moment the call can't reach you live — you will receive the notification once the connection is restored. Remote access resumes automatically when the lock is back online.
