Motion Detection

Motion detection is a way of defining activity in a scene by analyzing image data and differences in a series of images. The functionality be built-in into a network video product.
A multi-zone motion sensor allows you to define areas of a screen where you want to detect any visual changes.
The camera refers to motion detection as an “alarm”. You can select what you want the camera to do once the motion is detected. The factory default setting for motion detection is a single motion detection window covering the entire visible area.
The“Motion Detection”menu allows you to designate up to four separate windows with individually adjustable sensitivity to ensure you don't miss a thing when it comes to capturing important events or action.


After selecting“Motion detection” from the main settings screen, you may need to expand the size of the display window towards the right to see the four controls for individual motion detection windows. Each window can have individually adjustable sensitivity and threshold.


Pre-Record

Most motion-sensitive network cameras experience a delay between motion detection and recording. However, Phylink Camera buffer a 5-10 seconds pre-record stream. This stream can be record to SD card or NAS, it also can be remote playback via RTSP protocol. This feature allows users to review what occurred in those vital moments before the camera was triggered.



As demonstrated in the figure above, moving objects triggered motion detection recording function, but the delay problems caused the loss of data images in the beginning of the event, in some situations, these are very important. The Pre-record will help you catch everything.

Push Notification

Push Notification allows an application to listen for messages being pushed to it from the server. Our apps can provide uses even when they aren't running. It can receive message and alert you that new event had occurred even if you are busy doing other things or the smartphone is in sleep mode.
Apple & Google have worked around these limitations with a push-based design. They have come up with the concept of an intermediate server, namely APNS (Apple Push Notifications Service) and Google C2DM (Cloud To Device Messaging), to handle all push notifications between the device and the third party servers. Rather than forcing your app to remain open and constantly querying for updates, device OS (iOS and Android) itself instead listens for updates and notifies your application as and when they arrive. The result is decreased processor, memory, and battery use.

The camera takes motion detection as an “alert”. If any alert occurs, the camera can trigger an event and send the alert to Push Server. The Push Server generates a push message and sends to the smartphone.

If the camera motion detection trigger an alarm, the smartphone can receive a message push. You can block the alert in event settings of APP for avoiding interruptions.


Power over Ethernet

Power-over-Ethernet (PoE) technology enables switch/router and midspan systems, collectively named Power Sourcing Equipment (PSE), to deliver up to 15W of power over the data cable. The power-receiving system is called a powered device (PD). PoE enables power to be provided to the network device, such as an IP phone or a network camera, using the same cable as that used for network connection. It eliminates the need for power outlets at the camera locations and enables easier application of uninterruptible power supplies (UPS) to ensure 24 hours a day, 7 days a week operation. PoE technology is regulated in a standard called IEEE 802.3af and is designed in a way that does not degrade the network data communication performance or decrease the network reach. The power delivered over the LAN infrastructure is automatically activated when a compatible terminal is identified, and blocked to legacy devices that are not compatible. This feature allows users to freely and safely mix legacy and PoE-compatible devices, on their network.

PoE works across standard network cabling (i.e. cat-5) to supply power directly from the data ports to which networked devices are connected. Today, most manufacturers offer network switches with built-in PoE support. If an existing network /switch structure is in place, customers can benefit from the same functionality by adding a so-called Midspan to the switch, which will add power to the network cable. The following diagram shows how a network camera can receive power over a network cable.
If the camera using PoE connection, you DO NOT need the extra Power Adapter. It is very suitable for the installation locations which is no power outlet and Wi-Fi signal.
