- Playback & Firmware Failures
Many users report that device updates fundamentally break features they once relied on:
• One user described how their 4K NVR system, which initially worked fine, stopped displaying full playback clips after installation—only showing 2–3 seconds of video, or remaining stuck on a “loading playback” screen. 
• Another user shared that a firmware update on their 2K battery doorbell caused widespread functionality failures—motion detection, light response, and event recording all malfunctioned. Despite following Lorex’s standard troubleshooting guidance, the issue persisted until the user replaced the device with an older firmware version, which worked fine. 
2. App & Software Instability
The Lorex mobile app and NVR software are frequently described as unreliable and frustrating:
• One user attempted to play back events only to see incorrect or truncated clips. For example, the app would cut off footage just as a vehicle entered view—making the system unreliable for security needs. 
• Several users report that live feeds and timeline playback often freeze or skip, interrupting both automatic and manual recordings. 
3. Poor and Unhelpful Technical Support
Countless complaints highlight unresponsive or unhelpful customer service:
• A user attempting to troubleshoot wireless camera issues was promised a callback that never happened. Another rep simply read a script and couldn’t escalate the issue. 
• At the Better Business Bureau (BBB), many customers describe difficulty communicating with support due to language barriers, repeated troubleshooting steps, and refusal to escalate issues. 
• On copyright, one reviewer noted crashing apps, transparent-looking video—even from 4K cameras—and essentially no support. 
4. Hardware Reliability Issues
Technical faults are not limited to software—hardware has its fair share of problems:
• One buyer recounted a doorbell whose internal battery swelled after warranty expired, causing the case to open and disabling power. Lorex refused replacement absent extended warranty. 
• Another user faced perpetual battery drain and failed motion detection on wireless cameras, followed by Lorex’s refusal to accept a return despite initially acknowledging the defect. 
• For wired cameras, customers report constant freezing, failed connectivity, and NVR issues
