Home nas

[Enquiries]

Hi,
Firstly thank for the videos, they are really helpful and hence got me thinking before buying.
I presently have a DS215j running 4 cameras.
I don't use the NAS for data access much as i find it too slow. I have my NAS, PC's hard wired with a simple network switch which has POE that supplies the camera.
I presently have 4 Hikivision "DS-2CD2342WD-I".

At time when reviewing my recording i get stutters and recently missed the vital section of action because the recording missed 1-2 seconds.

I believe it is time to upgrade to hopefully stop the stutter in the recording, but the generally speed up the system, allow me to use the drive for storage better, i.e. windows explorer to show folders instantly rather delayed enumeration.

The biggest improvement would be stop false recordings of the changes to the view, i.e. sunlight and maybe trees moving.

What would you advise please ?

Thanks

Peter

Thanks for reaching out, and I'm glad the videos have been helpful to you!

It sounds like you're encountering a few issues with your current NAS setup, particularly with stuttering in your recordings and slow performance when accessing data. Upgrading your NAS could definitely help with these concerns, especially when it comes to better performance and reliable camera recordings.

1. Upgrading Your NAS for Better Performance:
Faster CPU and RAM: The DS215j, while a decent entry-level model, has limitations in processing power and RAM, which could contribute to the slowness and stuttering you're experiencing. I recommend considering something like the DS223+ or DS923+, which would provide a much more powerful CPU and more RAM, significantly improving speed and responsiveness in managing data.
Solid-State Drive (SSD) Caching: If your current setup involves a lot of read/write operations, especially for video storage and playback, you might benefit from adding an SSD cache (if your NAS supports it). This would help speed up data access and reduce the delay you’re noticing when browsing files through Windows Explorer.
2. Improving Camera Recording Performance:
Higher Video Throughput: With the new NAS, look for one with a faster CPU and more RAM, especially when it comes to handling the video feed from multiple cameras. The DS923+ would be a good choice because of its Intel-based CPU, which is better equipped to handle multiple streams of high-quality video.
Adjust Camera Settings: As for the false recordings caused by environmental changes like sunlight or moving trees, I recommend looking into the camera settings (e.g., adjusting motion detection zones or sensitivity). Some Hikvision cameras allow you to set specific areas to monitor, so you can ignore parts of the scene like trees or bright windows. Additionally, using a software solution like Surveillance Station on a more powerful NAS could help reduce false alarms by giving you better control over motion detection and alerts.
3. Storage and Speed Considerations:
If you haven’t already, upgrading to 5TB or larger drives (if your budget allows) would give you more room for data and improve your overall system performance. Drives like Seagate IronWolf or WD Red are solid choices for NAS storage and should work well with your setup.
4. Windows File Access:
The delay in enumerating folders could be caused by either a slow network or the NAS’s limited processing power. A more powerful NAS will significantly reduce the delay when accessing files via Windows Explorer. If your switch has POE, it might be good to check if your network speed is bottlenecking at any point; upgrading to 2.5GbE or even 10GbE might give you an extra speed boost.
With a £1000 budget, you could definitely upgrade to something like the DS923+ or even the DS1522+ if you want extra bays for future expansion. These models would provide the needed power for both your surveillance needs and general file storage, and they'd handle your network traffic much better.
