🛠 DIY Pro Tip: The “Speed” Factor
When installing wireless 4K cameras, your Wi-Fi signal is everything. A weak signal will cause lag or “offline” errors.
Expert Advice: Before you drill holes, take your phone to the camera’s location and run a speed test. If you get less than 5Mbps upload, consider adding a [High-Gain Wi-Fi Extender] to ensure your 4K stream doesn’t stutter.
