1. Whether it is a formal authorized dealer of the manufacturer, the general formal channels can often provide more favorable prices, high-quality services and high-quality products.
2. Product packaging: Does it include the manufacturer's name, address, trademark, and contact information? If there is no or lack of it, please draw your attention to whether it is a Sanwu product or a fake and shoddy product, because the product packaging produced by regular manufacturers must have the above content .
3. Whether the alarm host, infrared detector and door sensor have passed the national mandatory 3C certification. 3C certification is a certification that security products must pass, and it is also the primary factor to ensure product quality.
4. Whether the transformer of the alarm host is built-in, the national 3C stipulates that the host transformer must be built-in, and it is impossible for the external to pass the national 3C test.
5. Is the alarm siren built-in? If the siren is external, the security of the siren is relatively low.
Does the alarm host and infrared detector have anti-disassembly and anti-closure components? Without this, the self-protection ability 6. The report is poor, and it is easy to be maliciously destroyed.
7. Does the infrared detector have anti-glare function? See if there is this hardware, this component can prevent the false light of strong light.
8. Does the infrared detector have its own temperature compensation function? See if there is this hardware, this component can prevent false alarms caused by temperature changes.
9. Does the infrared detector circuit board have a frequency stabilizing element? This element can prevent false alarms caused by signals such as magnetic fields, pulses, co-frequency, high frequency, and sound.
10. Is there a low-power prompt function and related components? This function can prevent false alarms caused by unstable voltage or low power.
11. Is there a micro power consumption design? Does it have a power saving mode and a standard mode? This function can be used to charge the battery. 12. Does the infrared detector provide a 9-12V DC input interface, and has a dual power supply mode to ensure that the detector can not be used? Work intermittently to reduce the trouble caused by replacing the battery.
13. The type of battery used by the infrared detector? Generally, the ordinary AAA battery is easy to replace. The type has a large choice, and the block battery is not convenient and has a small amount of power.
