Techson’s product range has expanded with new camera series named EH1, EH2, and MH2. Thanks to AI-ISP technology, these models deliver excellent, full-color images even in low-light conditions, taking surveillance precision and detail to a new level. Read on for more details!
Techson has added three new camera types to its portfolio: the EH1, EH2, and MH2. What they all have in common is AI-assisted imaging, also known as AI-ISP. This enables the cameras to produce perfect, full-color images even under challenging lighting conditions.

But how exactly does artificial intelligence enhance imaging in surveillance systems?
Cameras have long included built-in automation to support the creation of high-quality footage. AI, however, takes this to a more advanced level. It can recognize what is visible in the image — what we call a scene: whether it’s a sunset, a snowy landscape, a human face, food, a document, or even a night-time cityscape.
Based on this, AI automatically adjusts key settings—such as color profile, white balance, exposure time, and sensor sensitivity. It removes reflections, compensates for blurriness caused by wind or vibrations, and intelligently brightens shadowed areas without overexposing them, while also toning down overly bright spots to reveal more detail.
At night, for example, AI compares multiple frames to reduce noise and eliminate motion blur. It also identifies the elements in the image and reconstructs the final version accordingly.
The so-called adaptive noise reduction used by AI ensures that important edges and contours remain sharp. Think of it like this: you’re looking at a photo and say, “It’s a pity this detail isn’t clearer—I wonder what’s there.” Or, “Too bad this part is blurry, or we can't tell what color that area is.” AI leverages the insights gained from processing millions of images and videos to give us clearer, more useful visuals.
In a previous article, we mentioned how advanced technologies are gradually making their way into the entry-level category. This has already happened with object detection, for example—nowadays, even the most basic cameras can distinguish between human figures and vehicles. And the same trend is happening with AI-assisted image processing. Intelligent imaging is no longer reserved for mid- and high-end cameras; it is now a feature in some entry-level models as well. This includes the EH1 and EH2 series, for instance. The third new camera type, the MH2, belongs to the upper mid-range category, thanks to its more powerful hardware and built-in extra functions.
But first, let’s take a closer look at the EH1 and EH2 cameras. The EH1 will be especially interesting for those who are just getting familiar with the system and are curious to see what artificial intelligence can really do.
The TCI EH1 C904 W AM and TCI EH1 E004 W AM cameras are available in bullet and eyeball housings, both equipped with a fixed 2.8 mm lens. Notably, a varifocal version with 4x motorized zoom will also be released later.
Among the three new models, the EH1 has the smallest image sensor. Its light sensitivity is 0.0005 lux—if that measurement even holds relevance at this level. Thanks to AI-assisted image processing, there is no need for infrared illumination; instead, the camera features white LED lights on the front, which can be turned on or off according to a schedule or ambient light levels. While SMD (Smart Motion Detection) is not available in this model, it’s hardly necessary, as the camera delivers full-color images at all times.
In addition to motion detection, the camera includes standard intelligent features such as line crossing, intrusion detection, and people counting—all powered by object recognition. As an added bonus, face detection is also available, although activating it disables other smart alarms like line crossing.
The TCI EH2 C004 W AM and TCI EH2 E104 W AM cameras offer everything the smaller series does, but feature a significantly larger 1/1.79” image sensor—nearly twice the size of the 1/2.9” sensor found in the EH1 models. Accordingly, sensitivity is also substantially higher—specifically five times better—at 0.0001 lux.
Moving beyond the entry level, we arrive at the TCI MH2 C004 W ADM and TCI MH2 E104 W ADM 4-megapixel, mid-range cameras. In addition to the high-sensitivity sensor already seen in the EH2 series, the MH2 models feature nearly double the data processing power. This enhanced hardware opens the door to a range of advanced intelligent functions. Alongside audible alarms, the MH2 offers regional statistics, heat mapping, loitering detection, and illegal parking detection. Most excitingly, object attribute filtering is also available. This means that beyond area monitoring and statistical functions, it’s now possible to search by clothing, hairstyle, age, gender, and other characteristics for individuals. For vehicles, users can filter by color, type, brand, and even detect electric-powered two-wheelers.
Of the three new cameras, the first— EH1—is best suited for those who are just getting started with this type of system, still exploring what AI-ISP actually means, and discovering the benefits of AI-assisted imaging.
The second camera, EH2, is a smart choice for those who want a slightly more powerful device while still staying within the entry-level range.
The third series, MH2, is ideal for environments where high sensitivity, AI-generated full-color night images, robust object recognition, and attribute-based filtering are all required.
