Tips to Prevent Latency in Your IP Security Camera

In the context of network video surveillance, latency denotes the in-between time when the frame is captured and when the frame is displaced. Many refer to it as end-to-end latency or even sensor-to-screen latency.

In words of CCTV security camera installation specialists serving across Sydney –

“Latency is the delay between the time the information is dispatched from the source and the time that information is retrieved in the final destination. The several stages which come in between them include – capturing, compressing, transmitting, decompressing and image displaying!
With every stage having its own time delay, the total of all stages put together is known as end-to-end latency. And this can be divided into 3 chief stages all influencing the whole IP system’s latency!

• Latency produced by the camera (denoted as processing image)
• Latency produced by the network (denoted as transmission latency)
• Latency produced by the retriever’s side (denoted as display latency, decoder latency and client’s buffer)”

What Causes Latency in IP Security Cameras?

• Image rotation 

Setting the rotation screen to stream videos at either 90 degrees or 270 degrees puts on more stress on the camera’s encoding processor. These pixels need to be buffered and rearranging before being sent to the system’s decoder. And that is what results in image latency.

• Resolution 

More resolutions denote more pixels to encode. Plus the processing time is more for a higher resolution and may result in more data per frame. Now if you have a limited bandwidth it could result in more delay in transmitting the information. This will cause longer buffer on the receiver’s end and lead to latency.

• Multiple Streams 

If you have set multiple streams from your IP security camera (like for instance different resolutions or rates), the whole processing time of those additional streams will lead to more latency.

• Latency Also Occurs In Image Compression  

Once an image is processed, it undergoes encoding to compress the data which is to be transferred. These image compression consist of numerous mathematical algorithms and as per the amount of data which is to be compressed, the time taken varies. This delay is referred to as compression latency.

Tips to Reduce Latency

• Always choose a lower resolution for your IP Camera system
• Reduce the number of enhancements like rotating, de-interlacing, scaling 
• Limit the number of streams with different settings as each adds load on the processor individually and causes latency
• Make use of high-frames as it reduces the delays which result in buffers
• Use display with the shortest refresh rate as feasible and also keep the graphic card driver up-to-date
• Also ensure that you possess a quality CPU processor along with ample capacity to simultaneously handle video streaming with other requests
• Ensure your network has good service and also configure it accordingly to meet your video quality demand
