I learned a bigger sensor is better for low-light situation, so 1:1/8'' should be better than 1/2:8''. But I see: IPC-HDBW5442R-ASE 1:1.8'' 4MP has 0.0007lux PC-HDBW5541R-ASE 1:2.7'' 5MP has 0.0009lux It's not that great difference, is it? So, to quickly identify a low light winner, is it...

who cares of his good/bad days? Only rudeness and nonsense is visible, congratulations. Neither a teenager. Oh fenderman, you, that can spend so much, ohhhhh my, why don't you make a round on apple/google store and buy some 30$ prog at random. "Oh but I don't need it", "Who cares? It's well...

@fenderman Completely unneeded harshness. 30$ or 300$ is common practice always knowing what you are buying. Simple as that. Probably it will worth it, nonetheless it's normal asking to know at least the major differences. But to be honest I did not use ANY of the new features in BI in the last...

Ok, but which are the new features of BI5? Which differences with BI4? I think before talking of $ upgrade, should be necessary talking of the features to decide what to do.

Yes, true. But when you have like 6xstreams recording and you want to see some events triggered, so contemporaneous sequential writing and random reading, well, maybe a 7200RPM could make a better job.

Normally Toshiba is around top quality for HDD, better than WD, maybe equal to HGST-Hitachi that is sadly been absorbed by WD. But I don't think WD will mantain the HGST quality... Of course it depends also on the model, a WD black will be superior than a Toshiba surveillance... Anyway, both...

Hi, I need an HDD for recording about 6 cameras. I found: Toshiba X300 4TB @103€ Toshiba S300 4TB @111€ WD purple 4TB @132€ I know Toshiba (like X300) are great general HDD, but for surveillance I see the purple is a common choice. But I could find a Toshiba for surveillance S300 at lower price...

I'm studying managed switches, so I would ask: if I buy a L2+ (or L3 switch), I know they can do inter-vlan: should I be ok without the router? Or do I need the router also with a L2+ switch? Or if I must buy a router I could buy a cheaper normal L2 switch? I mean: 1) L2 switch + router 2)...

But this way, if I put intercom into a VLAN in the managed switch, I imagine I can't look at the video doorbell into BI for example, as VLAN cannot communicate with pc. Not that so important, but is it correct?

Thank you. 1) in the direct IP connection I could manage only the one port from the Dahua POE switch. So if I put it on a managed switch I should fix it. 2) in the 2-wire connection, I will put the managed switch on the port from the external cable. So, both schemas, only one port to manage: it...

I found a manual install of 2-wire system and there is a pic pag.10: http://www.dahuasecurity.com/asset/upload/download/Dahua_VDP_2-Wire_VTH5222CH_Users_Manual_V1.0.0.pdf So I misunderstood the connection. The external cam will connect directly with RJ45 cables to the router with Internet (so...

I would like to install an intercom on a building with 3 apartments. So I thought of this Dahua VTO2000A-C + VTO2000A-B (3 button module). They must be connected to their POE switch VTNS1060A and to 3x 7'' internal monitors. Both external unit + 3x internal monitors are to be connected to the...

Thank you for the advise.

I think I'm in the situation of tigerwillow1: I can't buy all of starlight cams I need, simple as that. If normal cams are good on daytime, I think I'm not loosing that much. And *maybe* it's better than IR starlight, because of the deterrent led spotlights. I may be wrong, but I feel more...

Yes I understood. But I think I would use them better with led spotlights.
