First of all, we would like to sincerely thank our customers for their loyalty and help. 2022 will be a special year, your support gives us strength and is our best incentive to keep moving forward.
In the past year, we have released both new hardware and software to make the cameras fit for the future. Our progress will also allow us to continue releasing new powerful and innovative products, such as those with 2K video and smart PT features, as well as the mini cameras we show below. This year, we will launch a 4G solar battery camera that can be powered by a SIM card when there is no router nearby.
Last year, we also expanded our external sensor offerings to include radar, water leak, vibration sensors, as well as introduced an external siren box for the A7 Pro. In 2022, we would also like to develop more accessories to make home security even more purposeful and comprehensive with simple and affordable means. .
We are also aware that there are a few important innovations pending that we need to introduce as soon as possible, such as PT support via HiKam PC software for Q8 and A9 and Quad View on the mobile app. We have been focusing on these items since the beginning of the year and will do everything we can to implement them as soon as possible.
Of course, your questions, comments and suggestions are always welcome.
