VIDEO ANALYTICS: Software Based or Camera Embedded?

Today’s security market has many intelligent solutions that help aid security personnel in detecting, analyzing and responding to security events. From a video perspective, the decision often entails the decision to choose between a single device, like a camera, that has all the functionality embedded, or a software-based solution that allows choices of hardware platform and architecture. The decision to choose and “all in one” device is often not the correct path, as highlighted in the following table.

Feature Analytics in the Camera Software Based
(PureTech Systems)
Video analytics on commercially available edge devices and/or server hardware. No - Typically requires custom hardware. YES - Offered as hardened edge device, server-based or combination solution.
Video analytics work with all makes and models of cameras, including high resolution and thermal cameras. No - Brand and model specific camera and generally analytics is performed at 320 x 240. YES - Utilizing 640 x 480 resolution or greater, cameras provides greater area (range and width) coverage.
Video Analytics works on all brands of visible color (including megapixel). No - Choosing analytics in the camera limits selection to that brand. YES - Endless selection of camera models and resolutions.
Easy upgrade of video analytic software and hardware. No - Custom hardware tied to camera. Must replace/upgrade camera. Hardware processing power limited to custom hardware. YES - Runs on Intel processors. As Intel increases CPU power, analytic software algorithms can take immediate advantage for improved performance and more features.
Easy serviceability of cameras. Depends on manufacturer. YES - Replace camera core.
Video analytics works on cameras with fixed and vari-focal lenses. No - Generally only certain fixed lenses. YES - Supports any fixed or varifocal lens.
Easily integrates into VMS and PSIM systems using SDK or simple XML. Depends on manufacturer. YES - Software based solutions include SDI for easy integrations.
Multiple behaviors (zone entry, speeding, loitering, stopped, left behind object). Depends on manufacturer. YES - Software solutions provide you the widest range of behaviors. It also allows for quicker feature updates.
Multiple zones per camera. Depends on manufacturer. YES - No restriction on CPU power, means unlimited number of targets.
Track multiple targets per camera view. Depends on manufacturer. YES - No restriction on CPU power, means unlimited number of targets.
Reliably detect and classify (human, small vehicle, large vehicle, unknown) targets up to two kilometers. No - Max range is 900 M or less, depending on manufacturer. YES - Flexibility in camera choice, lens, resolution and algorithm provides for long-range detection. Distances well beyond a kilometer can be expected.
PTZ tracking of targets detected in a fixed camera. Continue PTZ tracking outside fixed camera view. No - Generally track only within fixed thermal camera field of view. YES - Continue tracking even outside fixed thermal camera field of view. This is referred to a single camera auto follow.
Invoke PTZ tracking on a PTZ camera by clicking on the target in the PTZ video. No – This type of command and control feature is not provided through a camera. YES - Requires use of PureTech client or integration with VMS.
Uses geospatial technology to enhance analytic performance (i.e. target real size, speed, direction, aspect ratio, etc.). Depends on manufacturer. YES - The ability to understand actual location (latitude, longitude, elevation) is available with software solutions.
Pinpoints (GPS location) target tracks on GIS map. Depends on manufacturer. YES - Dynamically providing target position information is available with software solutions.
Video stabilization (low and high frequency motion). Depends on manufacturer. YES - Software only video stabilization, independent of the camera make or model.
