[Data encryption (Batch change)]
Select “On” or “Off” to determine whether or not to activate data encryption.
•
On: Activates data encryption. Encrypts Stream(1), Stream(2), JPEG(1), JPEG(2), JPEG(3), and “AAC-LC” audio.
•
Off: Deactivates data encryption.
[Stream(1)], [Stream(2)], [JPEG(1)], [JPEG(2)], [JPEG(3)]
Select “On” or “Off” independently for Stream(1), Stream(2), JPEG(1), JPEG(2), and JPEG(3) to determine whether or not to activate data encryption.
[Encryption password], [Retype encryption password]
Set the password for data encryption.

Available number of characters: 4 - 16 characters
•
Unavailable characters: " &
IMPORTANT
•
The initial password is displayed in “MAC address” on the [Upgrade] screen. When using data encryption, make sure to change the password.
•
If you set data encryption to “On”, “Stream(3)” and “Stream(4)” become “Off”.
•
When the image capture mode is “3 mega pixel [4:3](30fps mode)” and data encryption is “On”, “2048x1536”, “JPEG” or stream cannot be selected.
•
If you set data encryption to “On”, the upper limit of the possible bit rate for stream transmissions will be limited to maximum 16 Mbps.
•
If you set data encryption to “On”, the snap shot button on the “Live” page will be hidden.
•
If you set data encryption to “On” for JPEG, images cannot be monitored using a cellular phone/mobile terminal. Additionally, the [Refresh interval] pull-down on the “Live” page is not displayed for JPEG with data encryption set to “On”.
•
The encrypted MP4 files and JPEG images cannot be viewed on the image playing screen in the browser. Download it to a PC and use the decryption tool to confirm it.
•
If you set data encryption to “On”, audio on the [Audio detection] screen will become inaudible.
Note
•
In order to view streams with data encryption set to “On”, you must install the viewer software.
•
If you confirm streams with data encryption set to “On” on the “Live” page, password entry for decryption is displayed. If you correctly enter the “Encryption password” that was set, you will be able to view images. When “Mic input”, “Interactive(Full-duplex)”, or “Interactive(Half-duplex)” is selected for [Audio transmission mode], only audio may be played until the password is entered.
•
Streams that have data encryption enabled for them are wrapped in < > in the [Live view] pull-down menu. Additionally, streams that have data encryption enabled for them are indicated by <Encrypted> in the setup menu pull-down menu.

When [Data encryption (Batch change)] is “On”, “AAC-LC” audio is data encrypted (“G.726” and “G.711” are not data encrypted). To encrypt both the image and audio, set [Data encryption (Batch change)] to “On” and set [Audio input encoding format] to “AAC-LC”.
•
For encrypted MP4 files and JPEG images, you can use the decryption tool to confirm the images.
