SanJie vs METAK Chime Specs
Audio customization
You have more tone options with the METAK system. It offers 58 unique long and short chimes to choose from. The SanJie model provides 26 chimes instead. Both units allow you to adjust the volume across five distinct levels. This means you can fine-tune the sound to fit your environment, whether you need a subtle alert or a loud notification. If you prefer a wider variety of sounds to distinguish different doors or events, the METAK option gives you nearly double the selection available in the SanJie package.
Volume output
The METAK door chime reaches a maximum volume of 120 dB. This is significantly louder than the SanJie unit, which tops out at 110 dB. Both devices are plug-in receivers, so you do not need to worry about battery power for the main alert unit. The higher decibel rating on the METAK model ensures the sound carries further, making it suitable for larger homes or noisy commercial spaces. If you need the loudest possible alert to ensure you hear the door open, the METAK specification provides a clear advantage in raw volume output.
Included hardware
The base package you receive differs between the two brands. The SanJie short name indicates it includes two sensors and one receiver. The METAK package comes with three sensors and two receivers. Having an extra sensor allows you to monitor an additional entry point, such as a back door or a window. The second receiver gives you the flexibility to place alerts in a different room. If you need to cover more entry points right out of the box without buying extras, the METAK kit provides more hardware for your setup.
Operating range
Both the SanJie and METAK wireless systems advertise a 500-foot operating range. This specification suggests that both devices can cover a single-story house or a small commercial building effectively. You can place the sensors on doors or windows that are far from the plug-in receiver without losing signal reliability, assuming there are no significant physical obstructions. Since the range is identical for both products, neither brand holds a technical advantage in terms of wireless distance coverage for your home or business.
Power source
Both the SanJie and METAK receivers plug directly into a standard wall outlet. This means you do not need to constantly replace batteries for the main chime unit. However, the METAK product data explicitly mentions that its sensors use AAA batteries with an ultra-low-power design that lasts one to two years. The SanJie data does not specify the battery life for its sensors. While both rely on plug-in power for the receiver, the explicit mention of long-lasting sensor batteries in the METAK specs provides more clarity on maintenance requirements.
Which Door Chime System Fits You
Users wanting maximum volume and tone variety
The METAK system reaches 120 dB, which is louder than the SanJie unit. It also provides 58 unique chimes compared to the SanJie model's 26 options. This gives you more flexibility to select a sound that suits your environment. The higher decibel output ensures alerts are heard clearly across large spaces or noisy areas.
Buyers needing multiple receiver locations
The METAK package includes two receivers, whereas the SanJie kit comes with only one. This allows you to place alert units in separate rooms or floors without buying extra components. Both systems use the same 500-foot range, but the additional receiver in the METAK set provides better coverage for larger homes or offices.
Shoppers preferring a white color finish
The SanJie wireless door chime is available in a white finish, which may blend better with light-colored walls. The METAK option is only offered in black. If your interior design favors neutral tones, the SanJie receiver and sensors offer a less conspicuous appearance while maintaining the same core functionality and range.
