It's been a long time that typical security surveillance systems only work reactively. It waits until an issue arise and things have gone downhill. For example: a 24/7 monitored alarm system is only activated after a break-in happened or a false alarm triggered. A traditional CCTV video surveillance system is only used for capturing and recording evidence and events. 

Although, sometime a security camera (real or fake dummy camera) could be used to deter the targets, security surveillance systems don’t actively alert before the bad things happen and prevent these events. 

With Active Deterrence technologies in video surveillance, a more proactive or a planned security strategy has been developed. The camera reacts before a situation occurs, therefore preventing an issue from ever arising. 

It can proactively deter intruders outside the perimeter and help prevent potential crimes with built-in features like AI-powered Smart Motion Detection SMD Plus, alarm siren, warning light, two-way audio and real-time notifications. Powered by the manufacturer awarding-winning deep learning algorithm, it provides high accuracy intrusion alarms and sends real-time event notifications. 

WHAT IS H.265?

H.265 video codec achieves a better compression ratio while maintaining high quality pictures at reduced network bandwidths.

H.265, also referred to as High Efficiency Video Coding (HEVC), is a type of video compression which directly affects the rate of streaming (how much or how little delay/glitching/buffering may be happening to a video stream), as well as the amount of space the video file takes up on a hard drive disk (HDD).

H.264 VS. H.265

The most common codec before this was, and to some degree still is, H.264, or AVC.  Most video used in online streaming or downloaded from the internet uses H.264 coding, as well as most security systems, until now.  Comparatively, HVEC (H.265) offers users double the data compression ratio (a significantly smaller compression size) without compromising the quality of the video, or a substantially improved video quality or higher resolution at the same bit rate as lower resolutions now.  H.265 supports video resolutions all the way up to 8192×4320, or 8K UHD.

WHAT'S H.265+ THEN?

An intelligent algorithm self-developed by the manufacturer Hikvision that can greatly decrease the bitrate of video based on a standard H.265 codec. Hikvision's H.265+ is such an optimized video encoding technology based on the standard H.265/ High efficiency Video Coding (HEVC) format. 

With H.265+, video quality nearly matches that of H.265/HEVC but reduces the transmission bandwidth and storage capacity required, due to three key technologies — prediction encoding, noise suppression, and flexible bitrate control.

It demonstrates incredible improvements in bandwidth reduction, data storage efficiency, and video content analyses. 

WHAT DOES THIS MEAN FOR SECURITY SYSTEMS?

In short, H.265 coding means you can stream an 8 or 12 MP IP camera’s video, or even multiple 12 MP cameras, with much greater ease over your network, and when your footage is stored on your NVR, you will be able to fit a significantly higher amount of footage onto a single HDD.  H.265 gives you better, faster streaming, and saves you money on the amount of storage you need to provide for your data on your NVR.

Motion detection is one of important task in security video processing and scenes understanding systems. It helps to extract crucial information from scenes which is used in many vision applications such as automated visual surveillance systems, object tracking and classification, activity understanding etc. It is a key security technology for effective crime detecting.

One persistent problem of motion detection for video surveillance is the high false alarm triggered by irrelevant objects, such as pets, insects, leaves, branches, raindrops, lights etc. It is not only creating excessive false alarms but also costing unnecessary time and money to deal with them. It also makes video search difficult in object tracking and classification,  and activity understanding.

Empowered by the manufacture's deep learning AI algorithms, Smart Motion Detection (SMD) Plus features built-in independent AI intelligent chip. The camera with this advanced AI function can classify human/vehicles at an accuracy of 99%, and trigger alarm in real time if necessary.

It supports quicker target search from recorded videos since it is capable of extracting and classifying human and vehicles from massive video data. It is easy for end users to trace and analyze historical information for Human & Vehicle. Huge amount of time and labor of event retrieving is saved.

The easy-to-operate interface of SMD Plus allows users to enable the function of classifying Human and/or Vehicle in only one click. The system also supports Real-time Alarm Push in WEB and DMSS.

In addition, there is the advantage of Alarm Visualization. The newly added alarm target classification on NVR/DSS/DMSS shows clearly whether there is human or vehicle intruding. Supported by the real time visual evidence, it is unlikely for users to miss or misperceive the real alarming events.

The functions above are highly practical and cost-effective, making SMD Plus an ideal choice of IP solution for small and medium-sized project customers, distributors and channel engineering companies with general requirements for intelligence.
