Define the need
Deterrence, evidence after an incident, person detection, door communication, smoke, intrusion, leak or emergency do not require the same system. Start with doors, lighting, visibility and habits before adding devices.
Local or cloud
Local storage reduces subscription dependence but needs backup and physical security. Cloud storage eases off-site access but adds fees, data transfer and vendor dependence. Verify retention, export, encryption and account closure.
Placement and privacy
Aim primarily at your property, limit street and neighbours, avoid bedrooms and bathrooms, disable unnecessary audio and inform occupants. Configure privacy zones and short retention. Rules vary for landlords, condominiums and common areas.
Cybersecurity
Use unique passwords, multi-factor authentication, automatic updates, a guest or segmented network, limited administrator accounts and removal of former occupants. Avoid devices without a clear update policy.
Reliability
Plan for power failure, Internet outage, cold, rain, weak Wi-Fi, false alerts and battery replacement. Test notifications with the phone silent and off-network. Monitored alarms require procedures, contacts and possible local permits.
