2 vs 3 Receivers Doorbell Chime
Receiver Count
The SECRUI unit includes two receivers, while the SanJie model provides three receivers in the box. This difference affects how many rooms you can monitor simultaneously without needing additional purchases. If you need alerts in three distinct areas, the SanJie setup is ready out of the box. The SECRUI option requires you to buy a separate receiver if you want to add a third location. For larger homes or offices, having an extra receiver included saves time and effort. The choice depends on whether two zones are enough for your current layout or if you anticipate needing a third point of monitoring soon.
Sensor Count
The SECRUI package comes with three sensors paired with its two receivers. The SanJie configuration includes four sensors alongside its three receivers. More sensors allow you to cover more entry points like doors and windows without buying extras. With four sensors, you can monitor multiple rooms or exterior doors right away. The SECRUI unit covers three spots, which is sufficient for smaller apartments or single-family homes with fewer entry points. If you have a larger property with many doors, the SanJie set provides more coverage initially. You can always add more sensors later, but starting with more reduces immediate additional costs.
Chime Selection
Both products offer a variety of chime tones to suit different preferences. The SECRUI door chime features 52 different chimes, including a special Christmas edition. The SanJie model lists 55 chimes in its specifications, though one feature description mentions 26 music options. Both units allow you to select from these tones to find one you like. The SECRUI option clearly states 52 tones. The SanJie data shows 55 tones, giving it a slight edge in variety. You can pick any tone for any sensor on the SanJie unit to identify specific doors. Both include LED indicators to accompany the sound, ensuring you notice the alert visually as well.
Volume Control
Adjustable volume is crucial for ensuring you hear the alert without disturbing others. Both the SECRUI and SanJie units offer five levels of volume adjustment. They both reach a maximum of 110 dB, which is loud enough for large spaces or noisy environments. The SECRUI unit allows you to adjust volume from 0 to 110 dB. The SanJie unit also supports up to 110 dB with mute options. Neither product has a significant advantage here, as both meet the same high-volume standard. You can set them to low volumes for bedrooms or high volumes for living areas. The memory function on the SanJie unit keeps your last setting after re-plugging, which is a minor convenience.
Operating Range
Wireless range determines how far sensors can be from the receivers. Both the SECRUI and SanJie door chimes advertise a 500-foot operating range. This distance is suitable for small to medium-sized homes, shops, and apartments. The 500-foot range ensures that sensors placed at distant doors or windows will still trigger the receiver reliably. You do not need to worry about signal loss in typical residential or commercial settings. Both products perform equally in this regard, providing robust coverage for most standard layouts. If your home is exceptionally large or has thick walls, you might need to test the range, but the specs suggest both are adequate for general use.
Expandability
Expandability allows you to add more sensors as your needs change. The SECRUI product notes that you can use additional SECRUI door sensors or doorbells for more safety. The SanJie unit explicitly states that each door opening chime can be paired with unlimited magnetic sensors. This means you can add as many sensors as you want to the SanJie system. The SECRUI option also supports expansion, but the SanJie documentation emphasizes unlimited pairing. If you plan to monitor many doors over time, the SanJie unit offers clear flexibility. Both systems allow you to pair different ring tones to specific sensors, helping you identify which door was opened.

You need alerts in three separate rooms

You want to distinguish different doors by sound
This unit supports pairing different ringtones to each sensor. You can assign a unique chime to the front door and another to the back. This helps you identify exactly which entry point triggered the alert without checking a display. The system remembers your last selected tune after power cycles.
You prefer a compact starter kit
The SECRUI option comes with two receivers and three sensors. It is lighter at 6.35 ounces compared to the heavier SanJie set. If you only need to monitor two areas, this kit provides 52 chime tones and 110 dB volume. It offers a simple solution for smaller spaces.
