Safety Plan - Backup Recording your IP camera or NVR to Second Location Automatically

The DVR/NVR is the primary devices people use to record footage from CCTV video camera. Sometime, video just got missing when we try to look back the criminal sense. Do you know we also can have secondary online backup your CCTV video in case the primary recording system go failed. There are three ways to play.

Edge Recording
The camera can keep recording on board as well as streaming back to your NVR recorder. Edge recording requires TF memory card installed in each of the cameras. As the TF memory card has limited storage, like 128G, we need to configure a recording plan to achieve longer recording time in the camera. The motion recording is the most common practical implement. Initial the recording only when the motion is detected on the scene. It can double up even triple up the recording time. The new technology H.264+ compression can help to save 30-40 percentage storage space from the TF memory card. It isolates the background from the sense and receives high compression rate without compromised the image quality. If both setup properly, 128G TF memory card will record over 30 days footage on board. TF memory card is the cost effective and reliable solution to backup the video online. Each of the camera is recording independently. Unless the whole system goes failed, you will have footage on some specific cameras.



FTP uploading
FTP upload requires an online FTP server. Most of the storage devices such as NAS has provided you a FTP server. You can either upload footage from the IP camera or the NVR. One thing important, the ftp upload function normally requires alarm event as trigger. That means the system only will start uploading when one or two alarm events are detected, such as motion detected, external alarm detected. The IP camera or NVR will not continue uploading the snapshot or video to your ftp server. The snapshot or video will keep in your ftp folder, it can be backup for as long as you want.


Email backup
We can simple create an email to receive the notification with snapshot from your IP camera. Remember only the IP camera can send the email with snapshot. The NVR will send the simple text email. Most of the email provider has policy. Too many false alarms will generate too much email sending to your account, which could violate the policy and cause your email account to be locked by your provider. We need to customize the motion detection to make the email notification as accurate as
possible. Another solution is we could connect the camera to an external alarm such as door contact or PIR sensor, the email notification will be more accurate. Only these external alarm devices are triggered will make the camera send you an email.

Redundant backup is your second plan to make sure the footage is available when the criminal case happens in the scene. Like what we said before, you never know how important until you need it.
