![]() ![]() In less extreme circumstances, security guards use real-time streaming to react more quickly and effectively to disturbances, conflicts, and potentially dangerous situations. Officers must instead clear room by room, a much slower process. But a person can move a lot in five or more seconds-if there’s a long video delay, the information is too old to act on. With access to live footage, officers and firefighters can navigate dangerous situations much more quickly and effectively-and the more real-time it is, the better.įor example, if a SWAT team has access to real-time live streams, they can pinpoint the offender’s exact location much more accurately and immediately rush to secure that location. Organizations can share video streams with first responders in crises, such as fires or active shooter situations. In emergencies, real-time streaming can help save lives. In real-time security and safety contexts, the delay of a fraction of a second can make a difference in outcome and safety. Latency does matter when you’re using video surveillance for live security purposes. Because you’re looking at old footage, a delay of a second or more will not make a difference in how you use the video and the information the footage provides. This includes many different functions, such as investigating incidents, creating a time-lapse, compiling reports, and more.įor viewing historical footage, you typically don’t need real-time or ultra-low latency streaming. In other words, footage of events that happened in the past. Historical footage refers to all non-live video. This makes low latency an important part of any video security solution. Keep in mind-almost all organizations use video security in both ways. Latency is very important for the former and less so for the latter. There are two main ways that organizations use video surveillance systems: for live security monitoring and for after-the-fact reporting and investigations. When does latency matter for video security? Real-time streaming (also referred to as near-zero latency) is commonly used in video calls and VOIP. ![]() ![]() This typically requires a latency of around 200ms or less. ![]() “Real-time streaming” happens so quickly, you can hardly perceive a delay at all. Real-time streaming (also called near-zero latency) “Ultra-low latency” in a video streaming context is considered under one second, meaning there’s less than a second delay between an event happening and you seeing it remotely on your screen. This is incredibly helpful for interactive mediums or less-passive viewing, such as for two-way video chat and live security camera feeds. Innovations in technology now allow the latency to be brought down even more. HD cable has an average latency of five seconds, and this is typically good enough for viewing footage passively-such as for prerecorded TV programming and historical footage in a video security platform. Traditionally, “low latency” is anything faster than five seconds. The standards for what is considered low latency are in flux as technology continues to improve. The lower the latency, the faster and more “live” it is. Streaming latency is the delay between a camera capturing an event and the event being displayed on the viewer’s device. What are low latency, ultra-low latency, and real-time streaming? We’ll talk about what you actually need for your video security system, what to know about LAN vs WAN, and how you can achieve real-time streaming with remote access. This post will explore the differences between low latency, ultra-low latency, and real-time streaming. If you use IP security cameras for live monitoring, it’s especially important that footage has low latency and it is as accurate and up to date as possible.īut what is considered ‘good’ or ‘bad’ latency when it comes to video surveillance? How does being in ‘the cloud’ affect it? Organizations in every industry use video surveillance to make decisions that affect the safety of their facilities, employees, visitors, and more. When it comes to video security, latency matters. ![]()
