Surveillance logs and notes are essential documentation for evidencing surveillance activities because they provide a detailed, chronological account of the investigator's observations and actions during the surveillance period. These logs should include times, locations, activities observed, descriptions of individuals, and any notable events, which are crucial for creating a clear narrative of the surveillance process.

This documentation can serve multiple purposes, such as corroborating videotaped or photographic evidence and ensuring that the findings can be accurately represented in reports or court testimonies. By maintaining thorough logs and notes, an investigator enhances the credibility of the surveillance evidence and demonstrates diligence in their investigative process.

While videotapes and photographs also play a significant role in documenting surveillance, they are often complemented by the richer context provided in the logs and notes, which can clarify the circumstances surrounding the visual evidence. Relying solely on witness statements or client feedback does not provide the same level of thoroughness and direct observation that surveillance logs and notes offer, making them the most critical form of documentation in this context.
