Camera selection starts with the view you need: an entrance, a loading area, an aisle, or a broad overview. This VideoSurveillancePA guide supports Northeast Remote Surveillance and Alarm, LLC (NERSA) by helping property teams prepare camera requirements for a site assessment.
Start with the job of each view
For each location, write down what staff need to see and when they need to see it. Note the distance, mounting options, lighting changes, and anything that may block the view. Bring examples of existing footage that is useful and footage that falls short. Ask the designer to demonstrate the proposed view under the conditions that matter to your operation.
Fixed cameras: dome, bullet, and box housings
Fixed cameras are a starting point for a defined view. Dome, bullet, and box describe common housing styles; the housing name alone does not establish image detail, weather protection, or suitability for your site. Compare the proposed lens, mounting position, environmental ratings, and recorded sample images before deciding.
PTZ cameras for adjustable views
Pan-tilt-zoom cameras provide directional and zoom control. Discuss who will operate them, what presets are needed, and which areas need a separate continuous view while the PTZ points elsewhere. The Axis PTZ camera overview provides examples of this category; individual capabilities depend on the model.
Panoramic and multisensor cameras for broader coverage
Panoramic cameras cover a broad scene from one position. Designs include single-sensor and multiple-sensor approaches, with different ways of presenting the image. Review the actual view and the detail needed at its edges, along with how staff will search and export recordings. See the Axis panoramic camera guide for an explanation of these designs.
Thermal and other specialist cameras
Thermal cameras use heat-based imaging. Treat specialist detection requirements as a separate design discussion: define the event to detect, the operating conditions, and how staff will verify and respond to it. Ask for a demonstration of the proposed equipment against those requirements. The manufacturer camera-category reference is a starting point for terminology, not a site specification.
Separate camera shape from system features
Wireless connectivity, analytics, and cloud management are system features to evaluate alongside camera selection. Ask how equipment receives power, where recordings are stored, who can access them, what ongoing subscriptions apply, and what happens during an internet outage. List any required integrations and have compatibility confirmed for the proposed models and software versions.
For analytics, define a specific event and an acceptable review process. Request a trial using representative activity and lighting before relying on an alert. For recording, confirm the required retention period, retrieval steps, and export process with the people who will use the system.
