From passive to active video surveillance : Traffic monitoring
RIVA IP cameras with special analytic filters help to improve traffic situations. Worldwide traffic increases constantly. Traffic jams, accidents, lack of parking spaces and environmental damages are the consequences.
At busy crossroads in Serbia, RIVA cameras with onboard video analytics are already used for adaptive traffic control. For that, traffic light systems are adjusted to the actual traffic demand to significantly improve traffic flows especially during rush hours. Thereby, not only the environmental impact is reduced, also time of all road users is saved and fuel costs as well as the number of road accidents decrease.
Only the VCA Presence module, which is already integrated in all RIVA devices as a standard feature at no extra costs, and the dwell filter are necessary. VCA Presence includes a tamper protection (bagging, de-focusing, moving) and the motion detection. Thus, an alarm is triggered if an object appears in a predefined detection zone. Up to 40 different zones per image can be set.
Another often used filter is the speed filter. Therewith, speeds of vehicles can be checked.
Furthermore, RIVA cameras with integrated video analytics can be used to collect data about the daily traffic. For that, the filter for vehicle counting is primarily used. It detects and counts vehicles without any problems also in dense traffic. Furthermore, it supports collecting traffic flow data for statistics. The obtained data can for example support town planning or determining speed limits. Also relationships and dependencies of traffic flows with other factors like weather, holidays or special events can be analyzed.
RIVA's RC6602HD and RC6702HD-6211 bullet cameras as well as RIVA's RC1202HD-6241 box camera represent solutions to continuously monitor traffic flows. RIVA's RC6602HD-5311 with remote/zoom control, is suitable for indoor and outdoor applications. Equipped with 34x IR LEDs, the camera provides images also in low light scenes. The IR range is about 25 meters. Not only VCA Presence, but also VCA Detect is included in the camera. This module includes the classification, direction and dwell filters.
RIVA's RC6702HD-6211 mini-bullet camera is suited for indoor and outdoor as well as day and night usage. The new RIVA camera comes with 12 built-in high power IR LED’s and an illumination distance up to 20m. Furthermore the RC6702HD has a variable focal lens of 3-9mm.
RIVA's RC1202HD-6241 is equipped with a SONY EXMOR 1/2.9” 1080p CMOS-Sensor that features a mechanical IR cut filter and is also ideally suited for the day and night usage.
