HOW TO RECORD AND PLAY BACK IMAGES TAKEN BY AN IP CAMERA?

Recording of pictures or video taken by IP Recording of pictures or video taken by IP cameras is a very useful feature that may operate in different ways according to your equipment. In this article, we will present the recordings of trigger methods and the media or store these records.

  1. Record triggering methods

The recording of images or movies by an IP camera can be done in different ways depending on your needs and your equipment. The registration may be triggered automatically during an event (alarm, motion detection, and programming) or manually by the user.

Manual Triggering

In live display in the browser of your computer, for example, you can click on the record button on the camera control panel to start a recording session. You can manually stop the recording by clicking on it again. Recording also stops when it reaches a limit on your storage space or limit in the administration of the camera. With manual recording, you control the images you want to save.

Continuous Recording

Continuous recording replaces any predefined trigger event or system settings. The recording continues uninterrupted until it reaches the end of its scheduled session, or when storage space is insufficient. If you are faced with critical conditions of order, the continuous recording is a great way to ensure that nothing is missed. This type of recording requires specific equipment (server, NAS, FTP, NVR, etc.). You can record continuous video feed of your cameras or take continuous pictures at regular intervals (eg every second) and save them on a server. The shelf life of stored data is also adjusted according to your equipment and storage capacity you have.

Triggered by motion detection

Recording is triggered when motion is detected by the camera or a camera video processing software.

Depending on the software you use you can customize a detection zone and adjust attributes such as detection sensitivity, threshold, object size, and trigger percentage to help you identify the target more precisely. Even if your IP camera is natively equipped with a motion detection feature, using an external software motion detection is still a powerful solution that will improve motion detection and security.

Triggered by Alarm

Product provided with an alarm I / O connector via an alarm registration is similar to the recording by motion detection, as both are triggered by an event. It works through an electrical current sent from the alarm to the IP camera. In practice, the electric current can be from an opening sensor connected to your front door for example, and when the door is opened, your alarm sends an electrical signal to the camera via the alarm connector I / O, which triggers recording.

Triggered by alarm and motion detection

You can combine the course record modes to be sure not to miss an intrusion. For example combine motion detection recording and alarm. The time at which recording is triggered depends on the mode that detects the first action.

  1. Programming and archive record

There is a variety of recording software photos and videos from IP cameras exist on the market. You can also customize your recording by defining slots or days in the week on which to record continuously or activate a recording with trigger by alarm or motion detection. For example, you can set the motion detection Day 7:00 to 22h and continuous recording entirely until the next morning between 7 am and 22h. This type of software can also support a rotation of archives to keep your space for new events. That is to say, if you define a data retention seven days during the eighth day, the system will record over the first day offering a rolling seven consecutive days of availability of images as set.

  1. What format to choose for records

Recording on a PC

This solution passes either through the camera’s user interface with a PC running Windows and Internet Explorer, or via software to install on a computer on your local network or on a computer connected to the stream from the camera via the Internet.

The quality and scope of software functions depend on the IP camera model. Most programs offer IP cameras to record video at specific times. The only drawback of this system lies in the fact that the computer on which you installed the management software must be started, which is not always the case. This solution also allows you to capture or save photos or videos of multiple IP cameras simultaneously (from 2 to over 16 times, but the same brand), and therefore is the most scalable solution for professionals.

If you have different cameras, you can turn to so-called multi-brand video monitoring software and thus able to manage multiple IP cameras of different brands.

  • Advantages

Requires no additional equipment, except a computer

Extended storage (disk and drive of the computer)

Multi IP camera management (of the same brand)

  • Disadvantage

Requires that the computer is on

Requires that you start recording if you do not go by software but by the camera’s user interface through the Internet Explorer browser

Memory card recording

This is a very easy function to implement, but reserved for IP cameras equipped with an SD / SDHC card reader. They usually offer the ability to save photos or videos following a scheduling or motion detection.

  • Advantages

Low cost storage devices

Stand-alone recording

Can remote access (via a Windows PC and Internet Explorer)

  • Disadvantages

Limited storage capacity (up to 32 GB)

No multi IP camera management on the same storage medium

No possibility of access via a smartphone to recordings on the memory card

Registration on a remote FTP storage, NAS or Cloud

Some IP cameras offer the ability to export images or videos by via FTP, a PC network, NAS or a Cloud (Dropbox for example). The advantage of this solution, when images or videos are stored on a remote server (online storage space from your ISP or by a service provider), is the security of data. It is impossible for thieves to steal the records if you have them stored online. But these backups on Cloud solutions are more suitable for export of images captured photos, rather than video sequences, often too heavy to be transferred through Internet bandwidth and storage by weight.

  • Advantages

Secure storage of records

Stand-alone recording

  • Disadvantages

Limited video backup capacity

Requested Internet bandwidth

Often requires a subscription with a provider for hosting the FTP if you do not want to have a server at home

Recording on NVR server

The last solution is network video recorders (NVRs for Network Video Recorder). These standalone servers, NAS closely in terms of functions, may therefore acquire and save images from video streams from one or more IP cameras, even if they are the same models or different brands. However, it will thoroughly check the NVR compatibility with IP cameras that interests you. The recordings, configurable directly on the NVR server Web administration interface, can be continuous, or triggered: alerts related to motion detection, schedules (days, hours). Movies recorded on HDD can be secured, some NVR models support RAID 1 capable of duplicating the data on two hard drives or more to avoid losing records in case of failure of the equipment. Finally, the administrative or ancillary functions of the NVR interface can be substituted for those of the IP camera; an interesting process with IP cameras entry does not even benefit from the functions NVR: Advanced configuration of recordings by motion detection triggers with acknowledgments of people, video recording formats, optimized for remote access smartphones, etc.

  • Advantages

Standalone device

Storage capacity

RAID

Multi IP camera management

  • Disadvantage

Cost of the device and hard drives

  1. How to read records

It is possible to read those records in different ways with a computer:

  • Online by connecting to the interface of your camera (often only with Internet Explorer) or storage space you’ve chosen (eg Dropbox).
  • Locally by accessing the memory card from the camera or by having downloaded the videos on your computer.

You have gone through how to record and play back images taken by an IP camera. Remember to be alert all the time to keep your house safe.
