What is 4k CCTV?

moemoe — Wed, 10 May 2023 15:48:51 +0000

4K CCTV is a complete closed-circuit surveillance system with cameras and recorders working independently from computer networks which reproduces UHD quality video. The acronym stands for “Closed Circuit Television,” but some variations exist. A 4K CCTV system is rated at UHD (Ultra High definition) resolution, which is 3840×2160 pixels or 2160p. 4K CCTV can be used on traditional coax systems but is more often found in IP surveillance systems using Cat5 or CAT6 wiring.

4K CCTV technology is one of the most recent and significant advances in the field of video surveillance. The term 4K refers to the number of pixels on a screen, with 4K indicating 4,000 pixels on the horizontal axis. This produces an image with four times the resolution of 1080p, the previous high-definition display standard for TV and video security.

The amount of depth and clarity provided by 4K technology is one of its most important advantages. Images in 4K are extraordinarily crisp and detailed. This degree of detail lets viewers detect more subtleties in images, making it simpler to notice tiny elements that would have gone missing previously. For example, using 4K technology, you may see individual scratches and dents on vehicles or features in a landscape that a lower-resolution system would miss.

Another benefit of 4K technology is the expanded image size and coverage. More pixels allow for more information to be displayed on the screen, making it simpler to properly cover a large area. An integrator working on a huge project can deploy fewer IP cameras in areas, each with a clear and detailed reproduction. Furthermore, users can benefit from 4K technology since it provides a more immersive experience by displaying more detail.

While there are still obstacles to overcome, such as the bandwidth required and storage availability, the future of 4K technology is bright. As technology advances, we may expect to see even more spectacular and detailed video surveillance systems that assist in reducing crime and preventing repeat offenders.

moemoe — Wed, 10 May 2023 03:24:53 +0000

With the advent of UHD 4K technology in the surveillance industry, user experience has improved exponentially over the last decade. Most users enjoy crisp and clean images generated by the recorders that can output 4K UHD on the HDMI connection. Many of these recorders can also convert lower-resolution images into 4K with upconverting technology. With all this new technology, user experience is at an all-time high, but there are still many items on the market that failed to meet the UHD requirements. Many of the items that are deployed in the field use inferior components like poor quality lenses and chipsets that create noise on the image. Much like everything else in electronics, you get what you pay for.

moemoe — Fri, 06 Mar 2020 01:23:56 +0000

Some of the key features to look for when shopping for a network video recorder are fairly basic. However, some manufacturers add additional performance and functionality that will come in very handy when performing daily tasks or attempting to play back video. For many of the lower cost 4K NVRs on the market, even reproducing live images can be a daunting task.

CORTEX 4K NVRs

Cortex security offers unique features like complete image control, analytics controls and full PoE power output for many of their premium models in the Medallion series. The cortex 4K NVRs are completely plug and play with medallion series IP cameras as well as capable of integration with Onvif models.

Users enjoy the high-performance capabilities of reproducing 4K images directly on live screens and remotely through software dedicated for PCs and smart phones. Unlike many units that are choked by lower performance bandwidth, these units have full capabilities that can connect to outdoor security cameras and can handle main stream the full resolution.

Fort Tampa security cameras and other areas in Florida weatherproofing is a vital feature in any model. Specific needs and requirements are necessary for outdoor security camera. Not only are the cameras exposed to high humidity and extreme rainy conditions, on many occasions the bright sun can distort the images and create issues with color and contrast balancing. Because of the encoding compression technology utilized by IP cameras its important to deploy a Network video recorder that can handle the stream fluctuations and larger package sizes.

How many sensor and DSP combinations are available for 5MP surveillance cameras?

IP bullets in 5MP

We know of at least 10 combinations for 5MP sensors with DSP chips that provide OSD controls and web-based settings. These IP camera components can mean the difference between easy installs and impossible headaches. Sony semiconductors manufacturers some of the best CMOS sensors for IP cameras that money can buy. Sony Cmos sensors come in a variety of performance models with some top tier models capable of keeping color in very low lit areas. Sont IP camera CMOS components can be called “Starlight” at the top end of the spectrum since the required light source is moonlight and starlight. At our Cortex QC6 testing labs, we often come across IP cameras that require very specific and confusing steps in order to setup network interconnectivity, making install much longer than necessary. Since 5MP IP cameras are so popular now, finding models with the same old problems and inconsistent performance is fairly easy in the worldwide market place.

5MP is also known as 2K (4MP is also 2K) or roughly half the size of 8MP images produced by 4K cameras. However, 5MP has many mainstream advantages like lower price and lower bandwidth requirements than 4K UHD. The analytic features and capabilities in many 5MP IP cameras are very accurate due to the high density of pixels. Installers throughout the United States and the Caribbean are currently installing the new five megapixel cameras in both network systems and traditional coax with great success.

One of the most popular analytic functions as line crossing. Line crossing on five megapixel IP cameras permits users a specific scheduled alert that can be programmed to notify via phone app or email when a person or object crosses the line and a specific pattern. Another very useful analytic function is perimeter protection. Perimeter protection can be installed to trigger specific events and alerts when a person or object enters a designated area. The cortex has integrated many of these basic analytic functions to their advanced IP cameras.

Folks tend to forget that 5MP resolution is much bigger than 1080p (which is actually 2MP in resolution). This means that connecting your 5MP IP or 5MP AHD cameras to a standard Full HD TV or monitor will not provide all the definition that you paid for in your CCTV system.

5MP IP cameras and 5MP AHD coax camera

The security camera industry is now jam-packed with five-megapixel offers in analog coaxial based technology and digital IP. Soon to come will be digital over coax in the way of EX-SDI 4MP and EX-SDI 5MP CCTV Digital camera models.

4K CCTV monitors are not really a thing since most UHD TVs can handle the UHD resolution and continuous abuse that is necessary for surveillance systems. However, using UHD computer monitors with higher refresh rates and higher levels of brightness ( like IPS) can sometimes make a huge difference in how surveillance video at eight megapixels is displayed. Regardless, when installing or deploying a new 4K surveillance system always make sure to compare scaling and aspect ratios and keep everything in line and paired-up properly to avoid distorted video.

At higher resolutions frame rate can also suffer or must be sacrificed in order to process a higher resolution image. Another key aspect of surveillance video in the UHD level is sensitivity in poorly illuminated areas. Cortex surveillance cameras in the 4K category use premium CMOS sensors specifically designed for low light areas and high color saturation during normal lighting conditions.

Why install five megapixel cameras? Prices are coming down dramatically in the five megapixel category and have replaced many of the other lower resolutions for video surveillance. Five megapixel cameras process through IP systems can be installed directly on your network or POE switches. When necessary, AHD and TVI over coax can be installed and when using hybrid DVR’s, you can use both.

4K Sony CMOS Camera

moemoe — Thu, 20 Sep 2018 10:23:43 +0000

Eight megapixel (4K) CMOS Sensors used for network cameras are now trending in the market. 4K network cameras can use many different types of brands for UHD cameras. 4K Sony CMOS sensors are well documented for having a fantastic night time viewing with very little noise and hi levels of light sensitivity. Cortex produces fix lens and motorized varifocal models that use the Sony 4K CMOS in their cameras.

4k Sony CMOS camera

These UHD cameras have advanced features in the software like analytics that can be used for object detection, line crossing, faced detection and Cross counting. The 16 : 9 aspect ratio of these CMOS sensors also provide an amazingly wide image viewing angle.

Cortex network video recorderS and software allow remote management and video recording of the video streams from these UHD network cameras. Additional streams can be managed for video management software like our RTSP on port 554 and substreams for cloud backup.

By integrating 4k Sony CMOS sensor into Cortex Network cameras this manufacturer provided superior night time performance that can be set for continuous color viewing instead of black and white. Color saturation during daytime and full lighting environments is also increased. The option of converting the image to black-and-white in order to take advantage of infrared lighting is a great option used to many times in excessively dark areas.

8MP IP Cameras for low light areas are extremely important and provide extremely wide angles because of their aspect ratio.

2018 brings the latest wave of UHD IP cameras with many different labels like 4K IP cameras, 8meg IPC, 4K IPC, 8MP Cams and many others. One of the key issues that has held back 4K IP cameras is frame rate. Up to now users had to choose between very high resolution at extremely low frame rates like 1-3 FPS because of compression and throughput technology. With the latest release of high-efficiency compression engines including h.265, more information can be sent via networks and processed through network infrastructures. This means much higher frame rates like 15 FPS or even real time 30 frames per second. Prices fluctuate because of processing power and chipsets inside the cameras.

4k IP camera Processors

Along with better compression and increased functionality a new generation of 4K CMOS sensors have also hit the market from famous brands like Sony and others. This has increased the output of 4K into the mass-market and the general distribution channels. Citing reports from statistic gathering agencies, many distributors in the computer and home automation markets have also increased their offers of 4K IP cameras and recorders to their clients.

UHD IP cameras can be found for a variety of prices which reflects the components used and housings that are chosen. Even the finish and painting on the 4K rated housings have a direct correlation with prices since higher quality finishes and polishing delays production which increases labor costs. 8MP rates Lenses for 4K cameras also have a huge influence on final costs with many manufacturers scrambling to find cheap solutions that can increase their competitive edge. Premium sensors like Sony and Aptina have an effect on the cost of production and engineering.

4k IP cameras and NVRs also benefit from the mainstream branding of 4K TVs and household appliances. This mainstream resolution is now a must-have for any new video product on the market and will soon be dominant in the CCTV and surveillance world as well.

Another advancement in technology that has also increased UHD penetration into the markets is storage size. Western digital and Seagate have both introduced 8 TB and 10 TB hard drives that are dropping in price very quickly. There is even a display for a 12TB HDD visible in the pictures from the last CPSE security trade show in China. These new mega storage hard drives allow simpler cased designs with smaller power supplies which in turn lowers the cost of recorder manufacturing. With so many affordable storage options and low-cost hybrid recorders, there is little doubt that 4K CCTV will make a big splash in 2018.

Be sure to shop the latest line of Cortex IP cameras and NVRs that will provide your clients with great value and long term performance.

New 4K CCTV Cameras

moemoe — Thu, 16 Nov 2017 04:21:48 +0000

The latest 4K CCTV cameras were on display during the China public security expo hosted in Shenzhen this year. Many new chipsets are available for UHD security technology which have dramatically dropped the market prices and created a whole new segment for video surveillance.

China public security Shenzhen 2017

2160p UHD CCTV was the most common ultra high definition option available during the show since many of the component manufacturers have really focused on producing affordable solutions for 4K. These components include the sensors but also items like lenses that are very difficult to manufacture in such high resolution. Up to just a few months ago, it was very difficult to find low-cost lenses in the category suitable for 4K. During our visit we noticed at least seven lens manufacturers with a heavy focus on UHD CCTV offers. Now that lenses are available in fixed wide-angle formats and varifocal for 4K CCTV cameras, it easy to assemble affordable, high value 4K systems that can be deployed throughout every industry that utilizes video surveillance.

A word of warning: with so many component manufacturer is fixated on delivering price driven 4K cameras and 4K recorders Byers must be extremely careful not to indulge in their price oriented decisions and test everything thoroughly in order to achieve a true 4K experience for consumers. An interesting point to focus on our the number of CMOS chip producers and have entered the market and are not competing with famous names like Sony, Panasonic, and Aptina. Although it will be sometime before these smaller CMOS chip manufacturers can perfect their technology and create the stability necessary for infield deployments, there will still be many buyers and manufactures that will attempt to prematurely use these 4K components and create the damage commonly seen during infield testing of new technology. A common word is “guinea pig” which is something that no integrator or installer wants to be. On the bright side, this means that very soon price competition in 4K will reach a boiling point which will create a standard for every day projects.

Like many security shows around the world, large format drones equipped with video imaging and UHD recording devices have a heavy presence. Many of the manufacturers or targeting military and government uses but also can be very helpful for commercial and industrial applications like land surveying and hazardous area surveillance. The price tag for many of these high tech toys can be astronomical but many times extremely worth it for commercial users. We noticed that firefighting and fire detection are a fantastic use of these military grade drones.

Drone based video surveillance is growing in popularity very quickly. Although it requires custom programming and some levels of artificial intelligence in order to achieve the desired results, we will soon see border patrol and seen awareness performed by unmanned drones.

Face detection in video surveillance is it common function which so far has served a little purpose but when used correctly has been useful for storage space saving and alerts of unauthorized individuals in a timescheduled zone. Using many new chipsets that provide additional processing power for artificial intelligence in CCTV engineering firms have put forth face recognition that can map a persons face. By creating a percentage based analysis, this new AI UHD can plot accuracy and compare the scanned faces to internal databases like blacklists that can quickly alert security forces of a potential threat. This new technology is available throughout the video surveillance world and will soon make its way to the field. Although some countries like the United States and Europe will quickly balk at the idea of giving up one’s privacy in the name of safety, it is highly likely that security concerns will outweigh any justification for shelving this technology. If programmed correctly, we envision a future where these AI CCTV tools are integrated into scanning 4K cameras and can even trigger access control locks and gateways. AI with it’s cognitive capabilities will surely change the landscape of the surveillance market.

Another technology worth mentioning that has also received a boost is the latest generation of EXSDI Which is now capable of 4mp resolutions. This Coax SDI technology is the only interface in the how megapixel range that can do full frame rate at full shutter speeds. This means real time display in the capability of recording at 30 frames per second. 4mp SDI or 4mp EXSDI is available from select distributors worldwide and requires an equally powerful serial digital interface on the recorders.

moemoe — Sun, 02 Jul 2017 03:52:55 +0000

Few people experience nightlife like in Miami. Revelers start the night at around midnight and will many times go past breakfast well into the sunrise. High energy partying is what Miami is all about and has been for many decades. But one cannot leave the party scene in South Florida without talking about Ibiza and Mallorca. These Spanish islands are also world famous for amazing nighttime disco’s and bars. Many of these destinations have no limit as to the length of the night.

ISC WEST 2017

moemoe — Fri, 14 Apr 2017 04:20:03 +0000

This year the Las Vegas security show was exciting for many new attendees. Displaying the worlds most advanced security countermeasures and preventative technology, the show is attended by countless exhibitors from around the world and visitors alike.

The security show in Las Vegas

While attendance was lower than expected, many of the exhibitors were very happy establishing new contacts with resellers and integrators. Speaking too many of the exhibitors about future plans, many said that they would repeat their attendance in future events.

One interesting technology that was added this year was drone warfare. With so many new UAVs out and ready for deployment countermeasures are hard to find and highly sought after by corporations and government officials.

UAV in ISC West 2017

Many devices and technologies were available on display to either incapacitate or completely take down drones that are trespassing and illegal airspace or pose a security threat. The technology ranged from radio frequency jamming to Nets that can be deployed.

drone killing rifle

As expected many of these new technologies Drew great crowds and fascinated spectators. In most cases some sales or future purchases were discussed. One conversation about drone take down veered off into trained eagles that are being trained to quickly attack and take down drones that enter secure areas.

Many manufactures backtracked from IP VIDEO to analog technology in the high definition form. Technology like AHD and TVI were prevalent throughout the convention and displayed by many famous name brands. Dahua also displayed their latest generation of CVI, another analog high definition format.

New resolutions throughout the show which generated the most buzz included: 3 and 4 MP AHD, 3-4MP TVI, 4K IP using H265 compression which allows increased frame rate and lower bandwidth requirements.

The theme for this year in the video category was definitely fisheye. With 180° and 360° views, many 4K Ultra HD IP cameras could be found with the dewarping technology built-in or on the accompanying NVRs. Multi sensor cameras in the four, eight, and 12 megapixel categories could also be found throughout the show. Many of these models require specialized software that can stitch the video images together to create one large panoramic view. Another option for these multi sensor cameras is individual use while utilizing only one housing.

In the access control arena, many companies displayed the latest in biometric technology. Radio frequency readers combined with fingerprint and retina scanning technologies were available. In many cases prices and availability fluctuated depending on the brands and country of origin.

In summation, this years ISC West show was not as exciting as we all hoped, but definitely did a great job in displaying new technology. We hope to see everyone again soon at ASIS EXPO.
