A smart camera (sensor) or intelligent camera (sensor) or (smart) vision sensor or intelligent vision sensor or smart optical sensor or intelligent optical sensor or smart visual sensor or intelligent visual sensor is a machine vision system which, in addition to image capture circuitry, is capable of extracting application-specific information from the captured images, along with generating event descriptions or making decisions that are used in an intelligent and automated system.[1][2] A smart camera is a self-contained, standalone vision system with built-in image sensor in the housing of an industrial video camera. The vision system and the image sensor can be integrated into one single piece of hardware known as intelligent image sensor or smart image sensor. It contains all necessary communication interfaces, e.g. Ethernet, as well as industry-proof 24V I/O lines for connection to a PLC, actuators, relays or pneumatic valves,and can be either static or mobile.[3]It is not necessarily larger than an industrial or surveillance camera. A capability in machine vision generally means a degree of development such that these capabilities are ready for use on individual applications. This architecture has the advantage of a more compact volume compared to PC-based vision systems and often achieves lower cost, at the expense of a somewhat simpler (or omitted) user interface. Smart cameras are also referred to by the more general term smart sensors.[4]

The first publication of the term smart camera was in 1975[5] as according to Belbachir et al.[6] In 1976, the General Electric's Electronic Systems Division indicated requirements of two industrial firms for smart cameras in a report for National Technical Information Service.[7] Authors affiliated in HRL Laboratories defined a smart camera as "a camera that could process its pictures before recording them" in 1976.[8] One of the first mentions of smart optical sensors appeared in a concept evaluation for satellites by NASA and General Electric Space Division from 1977.[9] They were suggested as a means for intelligent on-board editing and reduction of data.

Smart cameras have been marketed since the mid 80s. In the 21st century they have reached widespread use, since technology allowed their size to be reduced and their processing power reached several thousand MIPS (devices with 1 GHz processors and up to 8000MIPS are available as of end of 2006).

Having a dedicated processor in each unit, smart cameras are especially suited for applications where several cameras must operate independently and often asynchronously, or when distributed vision is required (multiple inspection or surveillance points along a production line or within an assembly machine). In general smart cameras can be used for the same kind of applications where more complex vision systems are used, and can additionally be applied in some applications where volume, pricing or reliability constraints forbid use of bulkier devices and PC's.

Developers can purchase smart cameras and develop their own programs for special, custom made applications, or they can purchase ready made application software from the camera manufacturer or from third party sources.Custom programs can be developed by programming in various languages (typically C or C++) or by using more intuitive, albeit somewhat less flexible, visual development tools where existing functionalities (often called tool or blocks) can be connected in a list (a sequence or a bi-dimensional flowchart) that describes the desired flow of operations without any need to write program code.The main advantage of the visual approach versus programming is the shorter and somewhat easier development process, available also to non-programmers.Other development tools are available with relatively few but comparatively high level functionalities, which can be configured and deployed with very limited effort.

The girl with the cat draws the attention of the child with the spoon, who spins around on the stool. As she prances with her toy off to the left, the SmartCamera automatically pans to follow, keeping her in the shot. The camera refocuses with the girl and cat in the center of the shot, revealing a rustic picnic table in the kitchen and exposing the rest of the large living room in the background.

The girls have an animated conversation as the camera focuses on the activity, smoothly sliding between them both while keeping everyone in view. The child with the cat walks backwards toward the living room and the other spins around on her stool as the camera automatically refocuses.

The girl finishes her snack and climbs down from the stool. As the girls approach the camera on the way to the dishwasher, the shot zooms out to encompass their path beneath the lens. The girls exit the scene and the camera stays focused on where they were.

After rigorous testing and research, we put together a list of the best security cameras you can buy right now. Keep reading and check out the video below, or if you want to put these cameras head-to-head, read our security camera comparison.

Although it works as a standalone security camera, the SimpliCam works best as a part of a SimpliSafe system. Together with SimpliSafe security sensors, the camera can monitor your home and give you visual access in cases of emergency. Moreover, SimpliSafe usually bundles the camera ($99 value) with its security system for free.

Ring jumpstarted the video doorbell market in the early 2010s, and after being bought by Amazon, it continued to produce innovative security cameras. Today, it has a completely separate line of home security cameras, divided into these models:

Other Ring camera models include motion detection, two-way voice, and Amazon Alexa and Echo integration like the doorbell cameras. Smart integrations let us control our home alarm system with voice commands and send our security video to various in-home displays of our choice. Ring cloud video storage costs $3.99 per month for one camera or $10 per month for an unlimited number of cameras installed in one address.

ADT offers a trifecta of security cameras: An indoor camera, an outdoor camera, and a doorbell camera. Together, these three cameras can watch over your home with their 1080p HD resolution, two-way talk feature, and smart capabilities that help them distinguish between important and unimportant events.

So far, those are pedestrian security camera traits. The very best aspect of ADT cameras, though, is that they come with the ADT home security system. These are not standalone cameras, so you can buy them only if you also buy a security system.

On top of that, ADT has a solid professional monitoring service, which includes video verification through ADT-connected cameras. Video verification occurs during emergencies. Rather than simply alerting the police that there might be a break-in in progress, ADT monitoring centers can briefly access security camera feeds to confirm the alert. That way, they can assist the dispatchers in identifying the intruder and also speed up police response.

With prices that start at just $29.99, Wyze makes some of the most affordable indoor security cameras with mobile app integration. Cloud storage is free for motion-triggered events, which makes Wyze a very affordable home security solution overall. Wyze makes its cameras for DIY monitoring.

Special features include geofencing (motion detection zones), Alexa compatibility, and the ability to detect specific frequencies. For instance, the camera sends mobile alerts in response to a smoke alarm.

Despite being a budget security camera brand, Wyze has been making a lot of high-tech cameras. They now have indoor and outdoor cameras, cameras that can pan and tilt mechanically, and even cameras equipped with a spotlight or floodlight for scaring intruders. And the best part? They are all more affordable than what we normally see in the industry.

The standard for high-definition security video is 1080p resolution. Arlo pushed the envelope with 4K ultra-high-definition on the weatherproof Ultra security camera, which costs $299. During our evaluations, the Arlo doorbell cameras, indoor cameras, and outdoor cameras automatically lowered their resolution if they detected low bandwidth.

Multiple setup options made Arlo cameras famous, too; cameras plugged in or operated wire-free, and magnetic mounts made setup hassle-free. The video was saved locally on a USB or to the cloud, free for seven days. Arlo cameras work best when grouped together to create an integrated network of security cameras.

Heads up: The latest from Arlo is the Arlo Pro 5S, a 2K spotlight camera with an extra-wide 160-degree viewing angle, dual-band Wi-Fi, and extended battery life. This latest camera works exceptionally well with the Arlo Home Security System.

The Nest Cam options include the plugged-in indoor model, the battery-powered weatherproof model, and the floodlight-equipped model. There are also wired and wireless video doorbell options. All these cameras share the same core features, including motion detection, person detection, and activity zones. Each can also be added to a Nest Aware subscription, which enables cloud recording plus up to 10 days of continuous recording at the highest tier. But even without Nest Aware, we still enjoyed mobile notifications from the cameras and three hours of event history with snapshots. That being said, we chose to keep our Nest Aware subscription because of facial recognition.

New Feature: You can now view live footage from the latest Nest Cams on Alexa-enabled smart displays and smart TVs. In addition, Alexa can now announce motion detection and doorbell ring alerts, as well as deliver two-way audio.

Blink sells easy-to-use wireless cameras for indoor and outdoor use. These are low-priced at $35 and up, yet excellent quality. Special features on Blink cameras include one-way or two-way audio, a motion sensor, customizable motion zones, a temperature sensor, and the option to use Amazon Alexa for arming and disarming by voice. 17dc91bb1f
