	Seismic point (geophone)	Seismic linear (CHE cable)	Infrared passive single-position	Acoustic	Magnetometric	Radio beam (pulse radar)
Detection range, R0, m, on average:
— a person armed with a small arm	5…50 (depending on the soil)	3…30 (with a length of CHE of 200 m)	5…30	100	3…5	5…10
— wheeled vehicles	300	50	50	500	15	30
&#8212 ; goose transport, equipment	500	100	80	1000	25…40	50
Probability of detection P0, typical	0.85..0.95	0.9. .0.95	0.7..0.9	0.7..0.9	0.95	0.8..0.9
Average time to false alarm T, hour, typical	10…30	5…10	10…30	2…5	50…150	50..100
Main sources of false alarms	Strong wind + vegetation, animals, water flows, microseisms	Strong wind + vegetation, animals, water flows	Birds, animals, heavy rain, sunset/sunrise, lightning	Thunder, wind + vegetation, rain, water flows	Lightning, roots of nearby trees in strong winds, power lines	Animals, strong wind, lightning
Classification goals	yes	yes	—	yes	—	yes
Direction movements	—	—	yes	yes	yes	—
Deployment time, sec, typical	10	600 (100m CHE)	120	60	30	30
Consumed electrical power (without radio channel), typically, mW	8…10	10	20	10…15	10…15	100… 150
Restriction on use	swamp	swamp, rocky ground	heavy fog, presence of trees in the field of view	no	no, for an unarmed violator R0 is 2 times less	high snow cover, water flows nearby
Conditions of deterioration of detectability	strong wind (AGC)	none	high ambient temperature (360 C)	strong wind (AGC)	for an unarmed intruder R0 is less, “magnetically clean” is not detected	no
Layout of the sensitive part of the CO	into the ground	into the ground, on the ground	on a stand above the ground	on a stand, branch	into the ground	onto the ground, on rack
Examples of CO (as part of SOS)	DT-562A (IREMBASS)	MA 2772 (CLASSIC)	IF-520 (EIDS)	Auxiliary in DT-562С (REMBASS-2)	DT-561A (IREMBASS)	HELPNCES (REMBASS)
