Mistakes to Avoid
1. Underestimating storage needs for 4K video.
Why it hurts: Higher resolution files fill up drives quickly, leading to lost footage if the NVR overwrites too soon.
Do instead: Look for systems with at least 4TB of HDD space for multi-camera 4K setups like the REOLINK RLK16.
2. Ignoring WiFi frequency compatibility.
Why it hurts: Using only 2.4GHz in a crowded area can cause lag or connection drops for wireless cameras.
Do instead: Choose cameras with dual-band WiFi (2.4G/5G) like the realhide 2K for more stable wireless connections.
Jargon Decoder
- PoE (Power over Ethernet)
- A single cable that provides both internet and power to the camera.
- NVR (Network Video Recorder)
- A central hub that stores video from all connected cameras onto a local hard drive.
Why it matters: Simplifies installation by removing the need for a separate power outlet at every camera location.
Why it matters: Allows for continuous 24/7 recording without relying on expensive monthly cloud subscriptions.
