The outer high-gain antennas of the vsee box (e.g., Taoglas MA950) are capable of amplifying the strength of signal receipt to 28dBi. In the Amazon jungle live test, the 4G/5G network packet loss rate decreased from 12% to 2.1%, and the uplink speed flattened at 45Mbps (19Mbps for standard antennas). The 2023 Volcano live streaming scenario in Indonesia shows that the gear with this antenna still recorded a 1080p/60fps live stream when the base station was 38 kilometers away, whereas the standard configuration dipped to 720p at 22 kilometers. But extending the antenna increases overall power consumption by 18%. It has to be paired with a dedicated battery module for vsee boxes (20,000mAh/129Wh) to support a 12-hour battery life. The weight and cost are accumulated by 420g and ¥880 per instance.
Active cooling solutions (such as Cooler Master XG850) reduce the highest core temperature of vsee boxes by 14°C (from 71°C to 57°C) when hot, preventing rate changes due to thermal throttling of H.265 encoding chips. The measured data from the Egyptian desert shows that following the installation of the radiator, the performance degradation rate of the equipment after long-time continuous working for 8 hours is just 3%, while that of the unconfigured group is 19%. This accessory employs double turbo fans (with an A rotational speed of 6500RPM±5%), and the noise is limited to 32dB(A). But it increases the overall power consumption of the device by 7.2W. It has to be used with a PD 100W quick charging head (with 94% efficiency). The cost is locked in at ¥1,299. It can extend the MTBF (Mean Time Between Failures) of the device by up to two times to 18,000 hours. Payback period of the investment is around 14 months.
The multi-channel storage expansion dock (SanDisk Pro-Expand 4TB) enables vsee boxes to capture 8 4K streams simultaneously to the RAID 0 array, with a maximum write speed of up to 980MB/s (the single card slot default is limited to 250MB/s). In the 2024 Tour de France cycling sequel production project, this design facilitates 12-hour 8K/30fps ProRes RAW recording without interruption, and the volume of material can go up to 14TB per day. ¥0.38/GB storage cost is saved compared to the traditional method. However, the working temperature of the SSD has to be controlled between 0-70° C. In case the shooting is done within the Arctic Circle, a 15W power consumption heating protective case will have to be used, increasing the total weight of the device to be more than 1.2kg, 36% more than the base model.
The leading Power management system (vsee Power Grid) has increased the proportion of equipment energy efficiency to 92.3% (compared to the industry average of 82%) through the technique of dynamic voltage regulation technology. In the journey to the Congo rainforest, it achieved off-grid operation for 72 hours together with solar panels (with 23% efficiency). The module has a wide voltage input of 16-60V and CAN be connected in parallel by 4 groups of batteries in order to achieve a constant output of 200W. However, the BMS CAN bus protocol is an additional ¥1,280, so the overall cost is 2.7 times higher than the initial power supply solution.
The protective kit military-grade (IP68/MIL-STD-810H certification) increases the impact resistance of vsee boxes to a 3-meter fall without damage. During the Alaska glacier venture, the initialization time of equipment was delayed by as little as 0.7 seconds at a temperature of -40°C (the standard version experienced a 32-second delay at -20°C). Pressure test indicates that, after the titanium alloy frame is installed, the machine possesses a static pressure capacity of 150kg (normal shell limiting value is 50kg), even though the weight accumulates by 280g and the efficiency in heat dissipation is compromised. The air duct needs to be redesigned (there is an increase in cost of ¥1,450). Actual measurement of the 2023 Antarctic research team shows that the protective kit reduces the rate of equipment failure in a 98% humidity environment from 17% to 1.3%.
Audio extension professional quality (Rode Wireless Pro) expanded vsee boxes’ dynamic range to 129dB by 32-bit floating-point recording. During live telecast of New Year’s Eve in Times Square, New York, the signal-to-noise ratio was up to 78dB (the integrated microphone was down to 62dB). The kit is capable of 4-channel TWS transmission with a delay adjustment of 11ms (the standard 26ms of the industry), but its individual power supply (2 AA batteries for 8 hours) contributes to the overall weight of the sound system, bringing it to 310g. The microphone sensitivity parameter (-36dB±1.5dB) needs to be carefully tuned to the device’s DSP algorithm. Package debugging is time-consuming and takes 4.2 hours of time per project.
The AI computing power expansion card (NVIDIA Jetson Orin) provides 40TOPS of local computing capacity to vsee boxes through the PCIe 3.0 x4 interface. In real-time 4K HDR-to-SDR live streaming, processing delay is compressed from 210ms to 28ms. During live streaming of the 2024 F1 Bahrain Grand Prix, this configuration made smart composition changes 120 times a second and increased the click-through rate of product placements by 19%. However, the peak power consumption of the expansion card is 35W. The cooling system of the machine needs to be tuned (there’s an extra ¥2,300 expense), and the level of CUDA core utilization needs to be optimized to more than 85% to prove the cost-performance advantage.
