Liquid superplasticizer is the most important admixture for concrete, in which PCE or polycarboxylate is the best performance and most efficient. Base liquid polycarboxylate allows to mix with many other additives to achieve certain admixture to be added on jobsite or concrete plant. High water reducing type and high slump retention type PCE superplasticizer are available to choose.

The video intercom system represents a modern and sophisticated residential service solution that enables two-way video communication between residents and visitors. It combines both image and voice recognition to enhance security, convenience, and overall reliability. This system not only improves safety but also saves time and boosts operational efficiency.
**Current Application Status of Video Intercom Systems**
Video intercom technology has evolved from analog black-and-white systems to color and digital versions. The trend is moving towards networking and smart integration, incorporating various media functions. Early analog systems used coaxial cables for audio and video transmission, while control signals were sent via microcontroller buses. However, these systems had inherent limitations. With the shift to digital networks, video, audio, and all control data can now be transmitted through a single network cable, eliminating many of the drawbacks of traditional analog setups. Moreover, this transition adds significant value by enabling advanced features such as remote access, smart home integration, and real-time monitoring.
In the future, digital video intercom systems are expected to become more deeply integrated with smart home automation, eventually serving as the central control hub for intelligent living environments. These systems come in different types—such as standard video intercom and network-based alarm systems—to meet the diverse needs of single-family homes, villas, apartments, high-rises, and community housing.
The main unit is equipped with a low-light, high-definition camera and infrared night vision, ensuring clear visibility even in dark conditions. Each unit can also support patrol and access control functions. Residents can use either contact or contactless IC cards to open doors, and the system can store thousands of card records for management review.
User extensions can be connected to various sensors like motion detectors, door sensors, smoke detectors, and emergency buttons. Users can arm or disarm alarms using a remote control, an IC card, or a password. The remote control can also function as an emergency button, allowing users to request help instantly without interrupting ongoing calls.
The management center can monitor alarms, access control, and system status across the building. It can record up to 32 events, connect to property management software, and provide real-time updates, search, and print capabilities. Additionally, it can perform round-the-clock monitoring of the building’s entrance, covering some functions typically handled by surveillance systems.
When choosing a video intercom system, users should first define their functional needs and then select a reliable manufacturer. It's essential to verify if the company holds proper technical licenses, has passed relevant inspections, and offers a strong warranty and after-sales support. Successful case studies and system compatibility are also important factors. For networked alarm systems in smart communities, careful evaluation is crucial. After selecting a manufacturer, users should compare different systems, focusing on installation, wiring, and debugging processes. Isolation of user extensions is also a key consideration.
**Troubleshooting Common Video Intercom Issues**
*Floor Platform Not Working?*
The floor platform serves to organize wiring, isolate protection lines, and sometimes includes decoding or video amplification. To troubleshoot:
1. Check all input and output connections for correct wiring, loose contacts, or short circuits.
2. Confirm signal input/output at each port. If no signal is present, check connected devices.
3. If the platform includes decoding, verify the address code is correct. Replace the decoder with a similar model to test.
4. If using IC chip decoding, ensure the chip is properly installed and oriented.
*Unit Host (Door Station) Not Functioning?*
1. If the display doesn’t light up, check the power supply voltage and internal wiring.
2. If the host functions improperly, there may be a microcontroller issue. Contact the manufacturer for MCU replacement.
3. If the camera isn’t working, it may be due to improper installation or quality issues. Test with a compatible camera.
*System Power Supply Issues?*
Most systems use 12V or 18V power supplies, often with over-voltage, over-current, and short-circuit protection. Some now use switching power supplies. Ensure the power supply is stable and supports battery charge/discharge protection. If the power is unstable, consider adding surge protection.
A well-maintained and properly configured video intercom system enhances security, convenience, and overall quality of life in residential settings.
