Self-installation of complex security systems does require careful planning and implementation. The following is a detailed step-by-step guide to help you complete the installation safely and efficiently.： --- ### **1. Requirements analysis and system design** -**Clear goals**: Determine system functions (such as anti-theft, fire/flood alarm, remote monitoring, etc.) and coverage areas (doors and windows, corridors, garages, etc.). -**Draw a floor plan**: Mark the layout of the house, the installation location of the equipment (such as camera viewing angle, sensor coverage), and the wiring path. -**Select system type**： -**Wired system**: High stability but requires wiring, suitable for houses where cables can be hidden before decoration. -**Wireless system**: Simple installation (such as Wi-Fi/Zigbee equipment), signal interference and battery replacement need to be considered. -**Hybrid system**: Wired is used in key areas, and wireless is used in others. --- ### **2. List of optional equipment** -**Core components**： -**Control panel**: System brain (such as Honeywell Lyric, SimpliSafe). -**Sensor**: door and window magnetic sensor, infrared motion detector, glass breaking sensor. -**Camera**: Indoor/outdoor models, choose above 1080P, night vision, cloud storage functions (such as Arlo, Reolink). -**Siren**: High decibel siren (≥100dB) and flash light. -**Environmental monitoring**: Smoke/carbon monoxide detector, water immersion sensor. -**Auxiliary equipment**： -**UPS power supply**: To prevent power failure. -**Smart gateway**: Compatible with multiple protocols (such as Z-Wave, HomeKit). -**Signage**: Warning “under monitoring" to deter intruders. --- ### **3. Step-by-step installation process** #### **A. Control center settings** -Choose a hidden location close to the power supply (such as the basement or wardrobe), connect the router and configure the network. #### **B. Sensor installation** -**Door and window sensors**: Installed between the movable frame and the fixed frame, the spacing is ≤1cm to ensure effective magnetic absorption. -**Motion detector**: Height 2-2.5 meters, avoid pet activity areas (choose the “Anti-pet” model). -**Glass breaking sensor**: Close to fragile glass, test the sensitivity (high-five simulates the sound of breaking). #### **C. Camera deployment** -**Outdoor**: Cover the entrance and driveway, and use a waterproof shell (above IP66) to avoid backlight. -**Indoor**: The living room and corridor have cross-viewing angles, and audio recording is disabled (subject to local privacy laws). #### **D. Alarm and power supply** -The siren is installed high in the house to ensure sound transmission. - Configure backup batteries (such as 18650 lithium batteries or solar panels) for critical equipment. --- ### **4. Network and intelligent linkage** -**Secure network**: Create an independent Wi-Fi network (VLAN isolation) for IOT devices and enable WPA3 encryption. -**Automation Rules** (through Home Assistant or MANUFACTURER APP)： -Automatically light up and send SMS/push notifications when the alarm is triggered. -The smoke sensor is linked to close the gas valve (must be compatible with smart homes). --- ### **5. Testing and optimization** -**Item-by-item testing**: Artificially trigger each sensor, check the alarm delay (ideal≤2 seconds) and APP notification. -**Troubleshooting of false positives**: Adjust the sensitivity of the motion detector to avoid curtain shaking or insect triggering. -**Stress test**: Simulate power failure and network disconnection to verify the switching of the backup power supply and the 4G module. --- ### **6. Legal and privacy compliance** -**Camera regulations**: Avoid pointing to public areas or neighbors (notices are required in some countries). -**Data storage**: Choose local storage (such as NAS) or end-to-end encrypted cloud services (such as Eufy). -**Emergency contact person**: Inform the property/neighbor in advance of the processing process when the alarm is triggered. --- ### **7. Maintenance and upgrade** -**Regular inspection**: Test the battery every month, clean up the camera lens, and update the firmware. -**Extensibility**: Reserve the interface for future addition of smart locks or face recognition modules. --- ###**Precautions** -**High-risk links**: Be sure to power off when 220V wiring (such as siren power supply) is involved, or consult an electrician. -**Backup plan**: Prepare a manual alarm button (such as the bedside of the bedroom) to prevent the system from being damaged. Through the above steps, a reliable safety system can be built even without professional guidance. If you encounter technical problems (such as port forwarding or automation logic), you can refer to the manufacturer forum or YouTube tutorial. There is no trivial matter in safety, and caution comes first!
