VIDEO SECURITY

KEY FEATURES

DEPA – making intelligence 
work harder.

Taking surveillance to the next level

Our complete IP surveillance solution, 

Sony Professional’s Distributed Enhanced 

Processing Architecture (DEPA

™

) 

platform, incorporates Intelligent video 

analytics to help your customers identify 

critical events. Unlike conventional 

monitoring solutions, DEPA systems 

provide enhanced intelligence to help 

surveillance operators take quick action 

and provide streamlined workflows. 

Intelligent alarm triggers improved 

performance

With triggers designed to spot motion, 

DEPA-enabled surveillance equipment 

assists security staff in seeing crucial 

events in real-time. 

The Intelligent Motion Detection and 

Intelligent Object Detection functions 

can be used alongside parameters set 

by the user. An alarm will be triggered 

when a virtual line is crossed or an object 

is moved from a specific location. 

This feature can also count how many 

objects enter a predetermined area, 

calculate an object’s size, determine the 

direction in which something is moving, 

and gauge its speed. These movement 

filters can dramatically minimise false 

alarms and target real alarms, so 

improving surveillance efficiency.

The filters can also be used to quickly 

and effectively retrieve images, cutting 

down searching times. For example, 

virtual areas can be set to search for 

items that have been removed or stolen, 

or the system can immediately retrieve 

footage of a vehicle moving the wrong 

way along a one-way street. 

Intelligent processing enhances 

efficiency

Unlike units that use separate image 

processing and costly software, Sony 

Professional’s DEPA design divides 

traditional processing into two tasks. 

Front-end processing is distributed to the 

endpoints of systems within cameras, 

while back-end processing takes place 

at the recorder.

Intelligent recording minimises storage 

and network resources

Users can also choose to stream  

and record only the events that cause 

concern when alarms are activated 

– therefore streamlining storage and 

conserving network resources. And 

because DEPA divides up the analytic 

tasks between cameras and recorders, 

the amount of video data transmitted 

from the camera is reduced. Together 

with the reduction in the storage 

capacity, this creates a far more stable 

and efficient system in comparison to 

conventional surveillance.

Sony Professional’s Distributed Enhanced Processing 
Architecture (DEPA

) platform revolutionises surveillance 

monitoring for almost any application.
