Installation Tips
Proper installation is key to getting the most out of your surveillance camera. Start by choosing strategic locations that cover entry points, high-traffic areas, and blind spots while minimizing obstructions. Mount cameras at a height that prevents tampering but still captures clear details, typically between 8–12 feet. Ensure cameras have power sources nearby, or plan for battery/solar options for wireless models. For outdoor cameras, use weatherproof casings and check that wiring is safe from moisture or damage. Adjust angles carefully to avoid glare from lights or windows, and test the camera feed before finalizing placement. Finally, secure all connections, enable motion alerts, and regularly check the system to maintain optimal performance.
