Basic functions and features	Iotecno	Other wireless systems	Other wired systems
1. communication between battery sensors and concentrator	2.4G 0db/1mW low power communication doesn’t interfere other wireless monitoring systems	same for all wireless systems	serieal communication bus failure causes lost of communications for all sensors on the same string.
2. redundency of communication between sensor and concentrator	dual-channel redundant communication channel significantly improve cmmunication reliability	only single channel, no redundancy	only single channel, no redundancy
3. CE safety and RED EMC certified	YES	YES	normally Low Voltage Certified, no high-voltage certification on full UPS string voltage
4. power consumption (please refer to explanation in  PPT presentation about battery balance issue)	ultra-low power sensor design allows powered directly from battery (0.6mA@12v) under monitored without affecting battery balance	usually 12-20 times higher than Iotecno which is bad for battery balance	usually 12-20 times higher than Iotecno which is bad for battery balance
5. using sleep mode to savfe power consumption	battery sensor doesn’t go into sleep mode, enable real-time response and fast alarm notification	some design go into sleep mode and only check batteryh conditions every half hour or more and lost real-time response	some design go into sleep mode and only check batteryh conditions every half hour or more and lost real-time response
6. sensing battery temperature	directly on negative pole connector to fastest response	some designs sense only on the surface of the battery casing which is much too slow to reflect internal temperature change	some designs sense only on the surface of the battery casing which is much too slow to reflect internal temperature change
6. fusing the battery connectors	battery cables are fused on every wires on both battery side and sensor inputs	may or may not be fused	may or may not be fused
7. dual communication paths to centralized management systems	concentrator provides RS-485 modbus output and system controller provide both RS-485 and TCP/IP modbus outputs	most are single channel	most are single channel
8. system flexibility	Windows CE (WEC 7) prvoide full compatibility with Windows servers system and networking	proprietory systems	proprietory systems
Additional features:
	easy integration with other wired and wireless sensors: temperature, pressure, power, I/O control, CFD etc.
	3 groups of multi-receivers per group for email alarms
	VNC remote desktop access from PC and modbile, automatic adjustment of different resolutions on mobile phone
	optional SMS alarm notifications
