How natural language search works in Security Center SaaS
2026-03-04Last updated
Natural language search in the Investigation task enables users to find relevant video clips by entering search terms in plain language.
You can use natural language search terms to describe what you are looking for. For example:
- "person wearing a red top near the loading bay around 3 pm".
- "person wearing a red top and blue pants yesterday afternoon".
- "person wearing a white dress".
- “white truck entering the car park yesterday afternoon”.
- “blue sedan parked outside HQ entrance last night”.
- "vehicle outside two days ago".Note:Location results are only returned if the location fully or partially matches one or more camera names.
You can also enter specific descriptors like brands and what people are wearing, carrying,
or doing. For example:
- Vehicle make, model, and color
- "Black Volkswagen Tiguan", "White Honda Civic", or "Red Tesla".
- Text or images found on a vehicle
- "FedEx", "UPS", "Taxi", and so on.
- Person holding an object
- "Woman holding a black bag", "Man holding a laptop", or "anyone carrying a backpack near the restricted area last weekend".
- Vehicles with additional attributes
- "Pick up with silver toolbox" or "Work truck with ladder on top".
- Descriptors going beyond clothing color
- "Man wearing a safety vest", "Woman wearing a toque", "Man in a black North Face jacket and grey hat", or "A person doing graffiti in November".
There are two ways to sort search results:
- Relevance
- Displays 500 most relevant results in order of relevance.
- Most recent
- Displays 500 most relevant results in reverse chronological order.
Note:
You can use filters to apply, include, or exclude some attributes related to
camera metadata, time, and location. You can also use filters on their own without natural
language search.
Investigation does not support searching for terms that include offensive language or
attempts to reveal sensitive information:
- Subjective terms
- Anything that cannot be determined by using an image of a person or vehicle. For example, “stealing”, “stupid person”, “speeding SUV”, “man holding a laptop”, or “woman next to a lamp post”.
- Hate speech
- Search term phrasings based on race, ethnicity, nationality, language, gender, sexual orientation, age, disability, health status, economic or social origin, social status, religion, or political views.
- Unsupported terms
- Searches that include phrases related to emotions, culture, or religion are not supported.
Time references
When time references are displayed in search results from natural language queries or the filter widget, they refer to the user's local time.
Each result is shown in the camera's local time, which includes the seek time in the video
player. For example, if you're an operator on the East Coast who manages sites on both the
East and West Coasts, a search for 4 pm to 5 pm will return results timestamped 4 pm to 5 pm
for the East Coast cameras, and 1 pm to 2 pm for the West Coast cameras. Your descending
results will also look out of order since you'll see results at 4:59 pm, 1:58 pm, 4:47 pm,
and so on.
Note:
For results outside your time zone, a globe icon
(
) is displayed next to the time stamps.
Hovering over the icon displays information about the associated continent and
country.
