What should an investigator ensure regarding their surveillance equipment before use?

An investigator must ensure that their surveillance equipment is fully charged and installed before use because this directly impacts the effectiveness and reliability of the investigation. If the equipment is not charged, it may fail during critical moments, leading to missed opportunities to gather valuable evidence. Proper installation is equally important; if the equipment is not set up correctly, it may not operate as intended, leading to poor quality footage or the inability to capture necessary information. Ensuring that these conditions are met allows the investigator to carry out surveillance effectively and increases the chances of successfully gathering crucial evidence for their case.
