What pain point does the home dual lens camera solved?

At the end of 2021 and the beginning of 2022, the security field suddenly has a lot of home binocular (or even multi-vision) camera products, which is a point of interest. I have introduced binocular, and even multi-vision cameras in panoramic cameras. In the field of professional security video surveillance, the use of binocular multi-vision cameras is to cover a wider surveillance area, detect, track foot traffic or improve area management, etc.. There are common types such as multi-sensor, multi-directional and PTZ fish ball linkage. The home binocular multiview camera is exactly these types, technology in the civilian sector to simplify, lightweight applications, and of course slightly different.

Types of products

There are four main types of home binocular and multi vision cameras that can be seen on the market today such as:

1.Binocular fusion, night vision full color

Dual sensor + dual lens, respectively, perceive the color and brightness, the depth of the two images fusion, without the use of any fill light, the night can also present a full-color image. Representative products are fluorite, such as fluorite C3X.

2. Bullet camera and PTZ dome camera linkage

Like the professional class of fish and dome linked panoramic camera, the combination of fixed-focus bullet camera and PT dome camera as a whole device. The bullet camera uses a lens with a smaller focal length to provide a larger view of the monitoring screen, and the PT dome camera uses a lens with a larger focal length to provide details for local or specific target close-ups, while the entire camera as a whole is connected to the network for remote viewing and operation via a mobile app.

Some do more distinctive program, PT dome can move or human tracking in addition, but also can be linked with the bullet camera, in the mobile app click on the bullet camera monitoring screen of any area, PT dome will quickly turn to the area to achieve a close-up of the target (because the PT dome lens focal length is larger), to achieve the monitoring effect of where to look.

At present, in the field of home Camera, The most well-known brand of binocular dual lens bullet and ptz linked camera is isulink Y5 which is 4K dual lens solar powered PTZ camera , bullet and ptz domewith 4X and 10X optical zoom

3.Hybrid zoom

The hybrid zoom is the fusion of optical zoom and digital zoom. Using two or more fixed focal length lenses (one with a smaller focal length, such as 2.8mm; the other larger, such as 6mm) in the same camera with a digital zoom algorithm to achieve a change in lens focal length (zoom in and out) in the same frame, with less pixel loss in the frame compared to full digital zoom, and faster zoom speed with almost no delay compared to mechanical zoom.

This type of product is to apply the multi-eye imaging technology in the field of smart phones and autonomous driving to the monitoring scene. The technology is relatively mature and has certain market demand and advantages. It should be very promising in the future. TPLINK has launched a series of such hybrid zoom products, including binocular zoom (4 megapixel binocular zoom indoor pan/tilt camera TL-IPC44GW binocular zoom version), trinocular zoom (4 megapixel trinocular zoom infrared network high-speed dome camera TL-IPC5420X trinocular zoom version),

ISULINK have also begun to make efforts in this area and launched some products.

ISULINK Y7 Multi-lens bullet and dome linkage camera Will be released soon

4.Splicing

This type of splicing products and professional class of surveillance camera splicing program principle, the use of more than 2 sensors and lenses in a housing, each sensor of the individual picture slightly overlapping, by aligning to provide a coherent panoramic picture of about 180 °. Home consumer security field of such products are relatively few (currently know TPLINK has a TL-IPC568VP-A4)

Pain points solved

Home consumer market is the future for a long time the security manufacturers focus on the field of competition, the market potential is huge. From being able to see, to see well, to see clearly, to see the intelligence is the manufacturers need to consider, but also the consumer concern.

How to do a good job of consumer security products, recognized by the market and consumers? The field of professional security advanced and mature technology applied to consumer security products is a good direction. The above-mentioned four types of binocular (multi-vision) home cameras are attempts in this direction, they solve the pain points of the consumer home cameras, can get the consumer and market recognition?

1. No need to use any fill light (including warm light, infrared light, etc.), the picture is even, the middle is not exposed, not dark around. At the same time avoid the discomfort caused by light pollution and the trouble caused by mosquitoes and insects false alarms (binocular fusion, night vision full color products).
   
2. Panorama and details are displayed simultaneously on the mobile app, picture-in-picture function, multi-angle viewing, without missing any moment (Bullet and PTZ dome linkage).
   
3. Hybrid zoom products solve the defects brought about by mechanical zoom lens such as slow zoom focus speed, easy to defocus when switching between day and night, difficult to move and track, easy to damage the zoom structure, and noise in the zoom process. No delay in the zoom process, fast and accurate focus, no defocusing during night vision, while the lens has no mechanical wear and tear, no noise.
   
4. Binocular splicing, greater monitoring perspective, compared with single-purpose panoramic camera, no distortion of the picture, high picture clarity.

Problems

1.Dual (multiple) sensors and lenses, which are more expensive than ordinary single-vision home cameras.

2. Bullet and PTZ dome linkage type camera to a certain extent does not achieve the role of 1 + 1 > 2. Because of the operation on the cell phone app to watch, cell phone screen size is limited, the meaning and value of watching two surveillance images at the same time is not too big, but brings new problems such as the need for greater network bandwidth, more storage space.

3.At the same, limited by the size of the cell phone screen, it is not very meaningful to watch the panoramic image with a large perspective on the cell phone.

The above four types of dual (multi)-view camera, dual-view fusion, night vision full-color camera technology requirements are relatively high, while only applicable to the fill light sensitive special occasions, general household occasions demand is not large. Bullet and PTZ dome linkage and dual (multi)-eye stitching of these two cameras is completely professional security camera field technology copy, in the field of professional security applicable scenes, powerful, useful. But the home scene, limited by the viewing and management of the back end is just a cell phone, it is difficult to play a great value.

Hybrid zoom should be the four types of dual (multi)-eye home camera is the most useful, the best future prospects. Especially the hybrid zoom + gimbal, applicable scenarios will be a lot. In addition, hybrid zoom + card machine (indoor moving head machine) is also a good application, card machine or moving head machine is limited by the size of the shell, it is difficult to install the conventional electric zoom lens, and hybrid zoom technology to solve this difficulty, making the home zoom camera miniaturization, lightweight is possible.
