Troublesome Dahua IP Camera access from OSX
If you're having trouble accessing your Dahua IP camera after recent Mac security updates to Safari, it might be worth trying a camera firmware update to resolve the issue?
This worked for me on two different cameras. The cameras I updated were both IPC-HDB3200C that were running 2.210.0001.0.R, build : 2013-05-17.
The firmware I used that fixed the blank screen issue on the iMAC's was General_IPC-HX3(2)XXX_Eng_P_V2.212.0000.0.R.20131206 which can be downloaded here.

March Networks IP Camera - NAS storage path syntax
If you have a March Networks IP camera that has the ability to write video to a SD Card or NAS, the correct path syntax for both CIFS and NFS when choosing to write to NAS is listed below as the documentation on this is not particularly great.

Dark (noisy) images affect DVR recording rates...profoundly!
DVR not recording as much as it supposed to?
You might want to download a 1 minute section of video during the day and do the same for a period of recorded video from the wee small hours. Compare the two file sizes. You may be very surprised.

Extend your DVR storage by turning on your cameras Digital Noise Reduction (DNR) feature.
A little used feature available on many CCTV cameras these days is digital noise reduction (DNR). Invoking this may significantly reduce the amount of storage required when the camera is put in low-light situations that introduce noise into the picture?
In the sample clips shown below, an extreme low-light situation was simulated by leaving the lens cap on.
The first clip was taken from a MPEG4 NVR and is 1 minute long with no digital noise reduction. The resultant video clip is 36Mb in size due to the noise (snow)!
The second clip was taken from the same NVR and is also 1 minute long but shortly into the recording DNR was turned on. You can instantly see the noise factor improves significantly reducing the overall file size by 30 times! The DNR enabled clip was only 1.2Mb!
If the cameras you use have these features and storage is less than ideal, this maybe a fairly easy fix?
