FIELD: security systems, particularly signaling barriers and detection means adapted to record direct influence of discovered object on the barrier.
SUBSTANCE: netted barrier comprises load-bearing posts, netted web and cable sensing member. Load-bearing posts are composed of three parts having different rigidity due to provision of shape- and dimension-variable transversal section for all parts. Each part has box-like cross-section in lower zone and U-shaped cross-section in central and upper zones thereof. Cross-sectional area reduces in transition from medium zone to upper one.
EFFECT: reduced rigidity of load-bearing posts to prevent intrusion without detection of influence on the barrier.
