Why Switching to Event Recording can Save you Time and Money

For those unfamiliar with the terminology, Event Recording is a camera functionality where it only records footage when something is actually happening. To put it in perspective, the opposite of this would be Continuous Recording, which means that a camera is essentially recording 24/7. 

The core component of what makes Event Recording work hinges upon the camera’s ability to recognize that something is happening. When it comes to security systems, sensors are this key ingredient.  

When you get down to it, there are a vast amount of sensors available on the market, including motion detectors, fire detectors, and glass break detectors, all serving different roles and most with the ability to be connected to and benefit from Angelcam’s cloud-based services. 

For instance, once you have a sensor installed and connected, an event detected by the sensor serves as a trigger for the cameras to start recording. Usually, they’ll continue to record for a certain period of time (eg. 30 seconds) unless there are more events coming from a sensor. In such cases, the recording time is prolonged.

What are the benefits of Event Recording compared to continuous recording?

  • No need to go through hours of useless recordings where nothing is happening. When using the Angelcam mobile application, you can easily navigate through a list of events for each camera, quickly viewing each respective recording individually.

  • Save internet connection data. In some cases, like when you need to remotely monitor your summer house, the amount of internet data your security system is using might be of paramount concern and make continuous recording an unnecessarily costly option. With Event Recording, cameras only send data when it’s needed. 

  • Lower Storage costs. Event Recording means that much less video, versus continuous recording, needs to be stored. As a result, that means lower fees from your recording provider. 

With Angelcam, there are three individual types of Event Recording: Post-Event Recording, Server-Pre Event Recording, and Device Pre-Event Recording. Each of them has different technical requirements and brings varying features and benefits to customers

Post-Event Recording

Post-event recording is when a camera starts recording after an event has happened. With regards to Angelcam, that delay is approximately 2 seconds.


  • No special hardware required 
  • Post-Event Only Recording is available for any camera that can be connected to Angelcam 
  • Decreases internet data consumption – Data is only transferred when the camera is recording


  • Video before the event is not available 

Server Pre-Event Recording

To help mitigate the aforementioned drawback of Post-Event Recording, Server Pre-event Recording utilizes Angelcam’s on-going connection to the video stream and continually stores a few seconds of what’s being recorded. Thanks to that, in case an event occurs, the video directly before the event will be available as well.


  • No special hardware required
  • Video before and after an event is readily available


  • The consumption of internet data is the same as it is with continuous recording. Since the storage of buffered video is happening in the cloud, our cloud needs to be connected to the camera permanently.

Device Pre-Event Recording

To be able to record what happens before the event, while eliminating the need to be continually using your internet connection, we’re developing a special firmware that is easily installed on your camera and stores the last few seconds of the video directly on the device and sends it to the Angelcam cloud when asked for it. This functionality will also be available on our AngelBox devices. 


  • Video before the event is available
  • Decreases internet data consumption 


  • Currently, the firmware is only supported on select cameras 
  • If your camera isn’t currently supported, the additional cost of an AngelBox is required

At this moment, Angelcam only offers Post-Event Recording but Server Pre-Event recording will be available in Q4 of 2019. Device Pre-Event recording is scheduled for Q1 of 2020.
