Im in China next week, but not looking at CCTV, the problem with China and CCTV is you have to see exactly what your getting right down to component level otherwise you end up with a load of tat.Then you have to buy enough of it to make it worth while, and theirs, which means that unless your selling to the trade the kit you purchased is old hat before youve sold it all.
I would never buy a single system of anything from China
Yes, I've found a lot of horror stories during my research so I am restricting myself to vendors which have had multiple recommendations in reputable forums - and I am buying the latest generation kit with the maker's branding, English language and upgradable firmware. There will still be risks - not least if/when something goes wrong with the kit even though it comes with a warranty - but there are also persuasive reasons for taking that chance. After all, the system is made in China so it should be no different in quality to the same kit which has travelled down the global distribution chain.
I intend to start piecemeal so that any initial problems will warn me off continuing with the bulk of my order. Then I'll come back to you, cap in hand.

Its not too far for us we cover upto North London, we have a few jobs in Basingstoke Windsor and Slough which are all your direction from us.
Couple of issues firstly we are Dahua installers not Hik but we can supply and install Hik. We cant install kit supplied by others we are NSI gold ISO 9001 which means everything we supply has to have a trail back to the supplier.
The other problem is that I do the broadlink kit for my house, and as a sort of hobby, we dont install it commercially none of my engineers will be familiar with it.
That said I can preprogram it here, is the gate already automated or do you need that doing too.
Thanks for that. My gate is double automated - control is either via the usual fob remotes or an ancient POE access control system which needs to be replaced. But I was intending to buy my video intercom kit from China so I probably need to find a freelance installer.

You will need the echo if you want to do anything by shouting at it
I suppose Reading is too far from sunny Sussex for you to come and install it for me?
(Hikvision video intercom with 3 monitors, Alexa, Broadlink and that analytic camera)

There are CCTV manufacturers like Dahua and Hikvision that make doorbells and entry systems that link to the CCTV and your smart phone, it wont be long until there is an alexa skill for those too
I will be getting a Hikvision video intercom for my entrance gates. Are you saying that when Alexa eventually acquires that skill I won't need any other device…or would that only dispense with the Echo (or the Broadlink)? Sorry for being a dummy.

No, My Alexa is not connected to any of my security, unless you count that its on the same router, eventually. The Alexa talks to the broadlink, the broadlink is a ir and rf transmitter, that can switch on anything with ir or rf. I have rf light switch's and of course my garage doors are rf. Controlling a gate or just about anything by voice is simple nowadays.
So I need one of these?

Or presumably Alexa Echo would do the same job without Broadlink?
In practice, how does it work? Can a PIR alert or video intercom visitor automatically trigger a camera window on your TV? Does it overlay whatever channel you are watching or do you have to switch AV channels?

I use alexa to to switch stuff on and off via a broadlink, I can control my garage doors from alexa but I rarely do, the timing on pressing the button putting my laptop in the boot and getting in the car is about right. but you can control just about anything now with alexa or google doo daa
Thanks - I'll have to find out more about this. Do I have to pick an NVR which is compatible with Alexa?

Play back recording 2mp my pool on the TV
Heyyyyy, nice pool! That picture looks pretty darn good but it must be upscaled to fill that screen estate.

A 4 or 8mp camera has the pickup to support but may have poor lens, chipset etc. You mention your 5k screen I'm assuming this has a price point etc. Buying cctv on frontend pixel count is like buying a car based on bhp alone,meaningless. A decent 2mp camera will give a better image than a cheap 8mp etc etc. Many people compare phone pickups to what good dslr can do. Just bear in mind it's never about pure specs
Understood James. I hope that Hikvision is a reputable, if foreign, make and that any of their cameras will be good quality.

Just now, PeterJames said:
Really? I have a 4k 65" tv in the lounge and 2mp camera full screen looks great
Full screen? That doesn't compute unless your video is being upscaled - in which case it should lose some clarity.
Do you have any functionality/interactivity on your TV feed? I would love to be able to bring my video intercom feed to the TV and then shout commands at it like "open the gate"...or even click a wireless USB mouse.

More to the point would you need that higher res? Its about the digital zoom and it really depends on the view that your looking at. We quite often come up against people installing much higher res cameras than us. But there is no point in putting a 5mp camera to view a small area all you are doing is using up your bandwidth and filling you HDD up with information that would not really be needed, a 2mp camera would identify an unknown person at around 10 metres easily in a small area like a corridor or hallway, or by your front door. A 4k camera would tell you how many hairs on their chin using digital zoom but why would you need that much detail when you have enough to identify them already?
I find that 4mp is more than enough for most projects unless your try to protect a football pitch
Thank you Peter. I do need good resolution as my monitor is a 5k screen and if I view a low res video it's the size of a postage stamp. But I will rely only on optical zoom cameras and up to 4MP. The zoom is for the cat - and for the one time in every decade or two when I might spot an intruder while watching live...

One issue would be the bandwidth of your network when it comes to planning out a system.
If the scene is the same size then 2MP vs 4MP is double the data, double the pixel density but also double the bandwidth on your network.
You can imagine how this increases exponentially as you increase camera res. It can be useful for a better image if you need to zoom in on recorded footage when looking at an incident.
This all depends on what the coverage is tho, many instances a 2MP is more than enough pixel density to cover the scene so that it out ways the bandwidth and cost of the cameras.
As for the monitor aspect of the question (pun intended), you need to consider if the output will support higher resolutions. You can also have issues with aspect ratio if the camera image is becoming stretched on the screen the image will look less clear even at a higher res. Monitors are sold by there graphics display resolution and ratio whereas cameras are most often sold as megapixel which is a different measurement.
Thanks for these good pointers but I won't be having any bandwidth worries with 1000Mbps up and down to the inter web and across my LAN plus Gigabit cabling around the house and probably only 5 cameras - a couple of which will indeed be 2MP but if I can find the right NVR to deliver 4MP I'll get a couple of those too with zooms as I like to interact and I need to find my cat!
My monitor is a big 27in 5k iMac and I'm running with a 4TB SSD drive plus 40GB of RAM so I could view almost anything on it.

I suspect he didn't know about 4k NVRs. Can you recommend one, eg Hikvision?I
-
I was asking a pro installer today about fitting a new POE CCTV system to coincide with my new 1000Mbps fibre broadband/LAN and when I told him that I would like to see 2560 x 1920 4MP video footage on my 5k PC monitor, he told me not to bother and choose instead 2MP cameras because my system would never be able to display video at higher than 1920 x 1080 without upscaling/interpolating it.
If this is true, why are people buying 4/5/8MP cameras? Is the NVR the bottleneck? Are there no NVRs capable of receiving/processing native 4MP+ video and sending it to the LAN without dropping data? For sure, I have seen 2560 x 1920 CCTV video on my monitor from a 5MP camera but when I looked more closely, it was less sharp than when viewed at 1920 x 1080 which suggested that it was simply being upscaled. Or is proprietary client software a bottleneck?
I can't believe that my system is the problem since it can play 4k Youtube H264 or H265 video very smoothly and it looks great.
Grateful for your thoughts.

Talking to myself but I have been assured elsewhere that this system will pick up non-Hik camera feeds (via rtsp) but only the sub-streams.
-
I'm about to install the HIK system (2nd generation) with 4 of their little monitors which do this out of the box, allegedly. They're not cheap but possibly more effective/efficient than keeping iVMS running all the time.

Cool dude of course
so get some extenders that allow hdmi and IR on one unit , if the distance is short like 10m then use a hdmi cable and separate cable for mouse and ir extender with it and your done
Ultimately it costs a small budget to do these things with extra bits and bobs
Thanks, I'll try that. Should have thought of it myself as I'm already using HDMI extenders to transmit my Sky feed to a remote TV and it works very well.

Then I would say you don't really know what your doing
Again put the NVR somewhere else and make whatever you need remote
:-) If I knew what I was doing I probably wouldn't be here asking questions.

Is the client or you not fussed about theft of device in that location?
The "client" is my dear old mum who has no security problem as she lives in a gated community. The system is to enable her to see her garden and the birds.

Y you need access ? To front ?
For mouse or IR remote control.

Use non Poe NVR and put it somewhere else?
Yes, I did consider that - but ongoing access to the front panel of the NVR is needed so there would be no escaping the disk chatter.
-
Thanks. I assume that SSD would have a shorter life but if noise limitation is paramount, might it be a price worth paying? Can you recommend an NVR which under typical light domestic load of, say 4 cameras, would be liveable with? Of course, ideally it would be removed from the living area but in this instance it is required to be close to the TV and accessible via remote control or mouse.
-
Hi, I'm about to order this system for residential use and wonder whether the monitors can pick up feeds from non-Hikvision ONVIF cameras on the same LAN? TIA.
-
Hi, looking for the quietest 8/16ch PoE NVR for installation in a residential living area. Any recommendations? Fanless? Solid state SSD drive? TIA.
Pro installer told me I'll never see extra pixels

I would take it on the chin. But I imagine a lot of people try to get the job done cheaply before realising that it was a false economy. If you're going to turn them all away, that's likely a big chunk of the market.
