Seeing is Believing: How Video Surveillance Tackles Packing Errors and Mislabeling in South African Warehouses
Herbert Voigt GmbH & Co. KG, a logistics company in Germany, used video surveillance, which linked barcode scanners and surveillance cameras to track and monitor the goods in the handling hall. This way, each scanned consignment was automatically assigned to the related camera and its images were stored in a local database. The system helped the company to reduce search times, prevent theft, improve quality control, and increase productivity. The video surveillance system also acted as a deterrent for potential intruders and vandals. The case study shows how video surveillance can enhance warehouse operations and security by providing real-time and historical data on the goods and the site.
While the list of root causes for packing errors and mislabeling is extensive, video surveillance can be a powerful tool to manage and reduce them. Here’s how each human factor, process issue, and external factor can be addressed with strategically placed cameras:
Human Factors:
- Inexperience and inadequate training: High-definition (HD) cameras positioned at packing stations can capture close-up views of staff actions. Reviewing footage allows identification of incorrect product picking, misinterpretations of labeling instructions, or improper packing techniques. This evidence can be used for targeted training interventions.
- Time pressure and fatigue: Pan-tilt-zoom (PTZ) cameras offer wide coverage of packing areas and can zoom in on specific stations during peak times. Monitoring activity patterns can reveal rushed work or fatigued employees, prompting adjustments to schedules or staffing levels.
- Poor communication and information flow: Cameras installed at department interfaces, like receiving and dispatch areas, can record interactions and document information transfers. Analyzing footage can expose communication gaps or misunderstandings regarding product details or order specifics, leading to improved communication protocols.
- Demoralization and lack of engagement: While video alone can’t directly address morale, strategically placed cameras with built-in microphones can capture interactions between staff and managers. Observing positive interactions and constructive feedback can provide evidence for improving workplace culture and employee engagement.
Process and System Issues:
- Inefficient and outdated practices: Video analytics software can be used with fixed overhead cameras to track product movement and packing processes. Identifying bottlenecks, inefficient workflows, or manual errors in real-time allows for process optimization and automation implementation.
- Lack of automation and technological integration: Cameras coupled with barcode scanners at picking stations can automatically verify item selection and label accuracy, minimizing human error and manual data entry mistakes.
- Inadequate quality control: Cameras positioned at conveyor belt exits and final inspection stations can provide visual evidence of packing errors before shipment. This can be used to improve pre-packing checks and implement post-packing verification procedures.
- Poor warehouse layout and organization: Overhead cameras with wide-angle lenses can capture the overall warehouse layout and product placement. Analyzing footage can reveal disorganization, clutter, or inefficient product positioning, guiding improvements in layout and inventory management.
External Factors:
- Supplier-related issues: Cameras at receiving docks can document the condition of incoming goods, capturing instances of mislabeling or inconsistent packaging by suppliers. This evidence can be used for communication with suppliers and improvement of their quality control processes.
- Unforeseen circumstances: Fixed cameras and PTZ cameras covering entry and exit points can document disruptions like power outages, equipment malfunctions, or sudden order changes. Footage analysis can help identify the source of the disruption and inform future contingency plans.
- Limited access to skilled labor: While not directly addressed by video, footage evidence of packing errors from inexperienced staff can highlight the need for additional training or skilled labor recruitment.
Unique South African Challenges:
- Language barriers: Cameras with audio recording capabilities can capture instructions and communication exchanges, allowing identification of potential misunderstandings due to language barriers. This can inform training initiatives or implementation of multilingual signage and instructions.
- Infrastructure limitations: While video surveillance might have limitations in areas with unreliable electricity, solar-powered or internet-independent camera systems can be considered. Additionally, footage captured during periods of stable power can be analyzed to identify inefficiencies or error patterns.
- High import volumes: Cameras at import clearance zones and receiving docks can document the volume and condition of incoming goods. This data can be used to optimize warehouse capacity planning, staffing allocation, and equipment needs during peak import periods.
Remember, effective video surveillance implementation requires strategic camera placement, proper lighting, and integration with appropriate software and data analysis tools. By harnessing the power of the all-seeing eye, South African logistics companies can significantly reduce packing errors and mislabeling, leading to a more efficient, accurate, and customer-satisfied operation.
