When shopping for surveillance security systems (recorders or cameras) you’ll definitely stumble upon H.264 and H.265. What those terms mean? Many people might associate H264 to security camera system. Many of the DVR and NVR we sell have H264 printed on the box or displayed at the system’s initial boot. But in reality, many of the higher quality videos, streamed online, uses H264 compression. H264 is the method of video compression that compares the motion in encoded image vs the stationary objects.
H264, Advanced Video Encoding, provides a good video quality at considerable lower bit rate than previous standard video protocols: MPEG-2, H263, and MPEG-4 part 2. There two things needed for H264 to work appropriately. 1) the devices capturing the video must be able to properly encode videos. 2) the playback device must be able to also decode the H264 videos back to playable video format. Since there is no standardized format for H264 and many different companies hold different patents, each security camera system might encode their H264 in various ways. That is why, each security system has generic files for their H264 compress videos.
H265 or High Efficient Video Coding, is new standard video compression that provides even more improvement than H264. H264 provides improved bit reduction of 57% at 1080p and 64% of UHD or 4K compare to H264. Since all our devices, smart phones to smart TVs, are recording or displaying at much higher resolution, it is even more important that we have HEVC compression. Many of the popular streaming website have encoded all their videos to HEVC or H265.

Both codecs work by comparing different parts of a video frame in order to find the ones that are redundant within the subsequent frames. These areas are replaced with a short information, describing the original pixels. What differs HEVC/H.265 from H.264 is the ability to expand the size of these areas into bigger or smaller blocks, called coding tree units (CTU) in the HEVC/H.265. The pattern CTU sizes can be from 4×4 to 64×64, whilst H.264 only allows a maximum block-size of 16×16 (CTU is particular feature of HEVC). An improved CTU segmentation, as well as a better motion compensation and spatial prediction require much more signal processing capability for video compression, but has a significantly less impact on the amount of computation needed for decompression. Motion compensated prediction, another great progress in HEVC/H.265, references blocks of pixels to another area in the same frame (intra prediction) or in another frame (inter prediction).
To conclude this article, we come to the most important question: What’s recommended for the CCTV systems? If your security system supports H.265 than that’ what you should use. For the same hard drive you’ll get more days of recordings compared to the H.264 compression. Make sure the camera and the recorder support H.265.When it work with video wall together in security room,Please choose the video wall controller can be support both format,iSEMC NP pro controller work well with the function like Recording & Playback Function,Multimedia Storage And Publishing,Electronic Map,KVM,Super Long Running Time,Linkage Alarm...That’s will help you a lot in Security project!
If you’ve started researching display types, you’ve probably encountered some terms like LCD, Projection cubes, Direct view LED and so on. So, which one is right for you? Well, that depends. Every display technology has unique strengths and weaknesses, and will be better-suited to some applications than to others. To help you get started, we’ve created a quick guide to the four leading display types.
LCDs (liquid crystal displays) are one of today’s most popular display options. You’re probably already familiar with LCD technology due to its widespread use in consumer electronics like smartphones, computer monitors, and television screens.
LCDs Work
An LCD is a flat panel display composed of a layer of liquid crystal between two pieces of polarized glass. When an electric current is applied, the liquid crystals shift, allowing light to pass through to create an image. Liquid crystals don’t produce their own light, so backlights are arranged behind the glass to illuminate the display.
Direct view LED, also simply called “LED,” has recently emerged as an exciting new indoor video wall display type. Direct view LED isn’t actually a new technology: it’s been used for decades in large, outdoor signage, but has traditionally lacked the resolution needed for close-proximity indoor displays. All of this changed with the recent development of very small LEDs, which have allowed manufacturers to produce much higher-resolution LED displays. Today, direct view LED is one of the most desired display options for indoor video wall systems.
Direct View LED Works
An LED display consists of hundreds of tiny LEDs (light emitting diodes) mounted directly on a flat panel. Each LED is essentially a miniature lightbulb that emits colored light when a particular voltage is applied to it. Clusters of red, green, and blue LEDs are grouped to create the full-color pixels needed to produce an image. Displays with very small LEDs and a fine pixel pitch will produce higher resolutions than displays with bigger LEDs and a large pixel pitch. However, these higher-resolution displays are also dramatically more expensive.
Common Applications of Direct View LED
Large scale architectural and signage displays
Control room operations
Blended Projection Systems
Blended projection systems combine the output of multiple projectors to produce an image that is larger or higher-resolution than could be generated by a single projector. Blended projection systems can display high-resolution images on a completely seamless surface of virtually any size and shape.
Blended Projection Works
Blended projection works by overlapping two or more projected images and gradually cross-fading their edges to produce a single, seamless image. A blended projection system can be designed with rear or front projection. In a rear blended projection system, the projectors are placed behind the screen in an enclosed room, where they either project light directly onto the screen, or onto mirrors that then reflect it onto the screen.
The full name of RS232 interface is "Technical Standard for Serial Binary Data Exchange Interface Between Data Terminal Equipment (DTE) and Data Communication Equipment (DCE)". The standard stipulates that a 25-pin DB25 connector is used, the signal content of each pin of the connector is specified, and the level of various signals is specified. The DB25 serial port generally only uses three pins 2 (RXD), 3 (TXD), and 7 (GND).
With the continuous improvement of the equipment, the DB25 pin is rarely seen now, and the DB9 pin is used instead. For the interface, the pins used by DB9 are different from those of DB25. They are 2 (RXD), 3 (TXD), and 5 (GND). Therefore, the RS232 interface is now called DB9.
Since the RS232 interface standard appeared earlier, it is inevitable that there are deficiencies, mainly as follows:
(1)it is incompatible with the TTL level, a level conversion circuit is needed to connect with the TTL circuit.
(2) The transmission rate is low. In asynchronous transmission, the baud rate is 20Kbps.
(3) The interface uses a signal line and a signal return line to form a common ground transmission form, which is prone to common mode interference, so the anti-noise interference is weak.
(4) The transmission distance is limited. The standard value of the maximum transmission distance is 50 feet. In fact, it can only be used at about 50 meters.
RS485 has several advantages over RS232:
(1) The electrical characteristics of RS-485: Logic "1" is represented by the voltage difference between the two wires as +(2-6) V; Logic "0" is represented by the voltage difference between the two wires as -(2-6) V Said. The interface signal level is lower than RS-232, it is not easy to damage the chip of the interface circuit, and the level is compatible with TTL level, which can be easily connected with TTL circuit.
(2) The highest data transmission rate of RS-485 is 10Mbps.
(3) The RS-485 interface is a combination of balanced drivers and differential receivers, with enhanced anti-common-mode interference capability, that is, good anti-noise interference.
(4) The standard value of the maximum transmission distance of the RS-485 interface is 4000 feet, which can actually reach 3000 meters, and the RS-232 interface only allows one transceiver to be connected on the bus, that is, single station capability. The RS-485 interface allows up to 128 transceivers to be connected on the bus. That is, it has multi-station capability, so that users can use a single RS-485 interface to easily establish a device network.
Because the half-duplex network composed of RS485 interface generally only needs two wires (we generally call it AB line), the RS485 interface adopts shielded twisted pair transmission.
A video wall is a collection of screens that are combined/tiled together to create one large display. Typical display technologies used include LCD, direct LED tiles, rear-projection and laser displays. It can be used in control rooms, meeting rooms and as a digital signage display. Industries include corporates, hospitals, retailers, government offices, churches, schools, casinos and hotel receptions.

This article will define what a basic video wall is, the components you need to buy and tips for designing appropriate content.
What are the benefits?
Grab’s attention
Because of their large size, video displays are able to command attention. They are hard to ignore by customers, employees, or visitors, which makes them an ideal tool for an organization’s branding or informational campaigns.

Employee Time
Video walls can help perform tasks an employee normally would. It can free up employee time so they can work on more pressing tasks.
Large malls can display maps on video display
Parks and stadiums can display frequently asked questions
Hospitals can display services offered online
Different Types of Content Simultaneously
A video wall that is powered by content management software is designed to display different types of content simultaneously. For instance, a campus can use a video wall to display maps, school events, and useful information like weather, news and social media.

Video Walls across Industries
Traditionally, video walls especially LED ones, have been used in retail for advertising and at events. Costs were high and content management wasn’t as evolved. Today, video walls are cheaper and more affordable for small and medium businesses. They are so diverse and thus are used across a large range of industries.

Support Content Customization
The content management software enables businesses to customize and personalize the content displayed on the screens.
Different content can be displayed at different times of the day e.g., a restaurant video wall can show different breakfast, lunch and dinner menus.
Can Increase Sales
Retail businesses that use digital signage can improve their sales by 32%. Retailers can use a video display system to alert thousands of target customers.
Can Improve the Customer Experience
Visual displays can combat customer dissatisfaction resulting from unpredictable waiting times. Leading service providers have been using this trick to keep clients waiting patiently.
Consumers prefer Shopping in stores with Video Displays
The video displays give customers more information about the products, help to upsell complementary products and overall improve the ambiance in the store.

How to Design Content for a Video Wall
Video walls display information. Ideally, this would be to the right target audience at the correct time. Otherwise, this communication and advertisement channel will be less effective.
So how does one make sure that their video wall system plays its role effectively? Below are some design tips:
Use high-quality realistic images/videos
Like any visual, high-quality images and videos will easily command anyone’s attention than poor quality visuals. Even so, one should refrain from using heavily filtered pictures or videos.
Keep text short and to the point
As a rule, any text on a display wall system should be as concise as possible. A single line should contain a maximum of 5 words. Anything above five words will look cluttered and harder to read. Also, texts should be large and colorful enough for anyone to read without straining.
Use the right screen brightness
Lighting affects the visibility of the content displayed on the video wall’s digital screen. As an example, target viewers can hardly see content on a dim screen during a bright day. It’s important to adjust the screen’s brightness according to ambient light.
Do not clutter the video wall
While a single video wall system can display multiple types of content, it isn’t advisable to stuff it. A professionally designed video wall should contain an adequate white space to let readers view or read through the content easily and quickly.
