Ip And Analog Mix And Match

Since when were IP cameras expensive?

I could buy 4 1080hd IP cameras for that kind of money. Someone's making some money at amazon.

What 1080hd IP camera?

AXIS?

 

Anyway your £200 IP camera is still at least double the price of a reasonable analogue one isn't it?

Who would use HD-SDI if IP were the same price range

I'm going down the sdi route. Long term id say ip will rule but not for a few years Imo. But who knows how high sdi will go. Cheap ip cams have huge issues currently imo

You haven't looked at the other end. It's ok saying analogue is £100 per camera but you have forgotten that something needs to record these cameras. Quite often IP works out cheaper in total cost ownership terms than analogue.

IP signalling is far cheaper than analogue but the market is full of analogue so if your argument above held water Redcare and Dualcom would be bust by now.

The main reason IP devices are not used IMO is because them majority of the people in the industry are too thick to understand it.

Can you elaborate further on solution to a problem, please.

 

We are talking typical scenario: driveway, garage, shop, warehouse, vandals, thieves

not industrial espionage, casinos, banks, nuclear power plants, terrorists, drons

Others are much more experienced on the practical side, I'm more technical/theory orientated. What I mean by "solution to a problem", is a system proposal to secure your premises. First thing would be a site survey, to identify weak points, points of attack (so to speak), lighting, etc., then what type of camera is best suited to cover an area from which mounting point, etc. After this is done, is when you would look at your options such as transmission method (analog, IP, HD-SDi), recording, etc, while taking into consideration which functions you may like to have (phone access, storage times, etc) and ofcourse your budget.

The point is that the first steps above, apply to all cameras whether IP/analog/HD-SDi and apply whether you want Internet access or not. Concentrate here first especially if your on a tight budget as it will end up costing more to put right.

I would ask this another way, on a installation where both IP and HD-SDi are viable options, why would you over complicate it with IP? While IP may not be a challenge for most, it does introduce more opportunity for failure with no real benefit (in such an install).

Besides, the only thing HD-SDi is missing is volume, at the same volume, equivalent quality HD-SDi and IP cameras, the HD-SDi camera would be much cheaper, infact some have said a HD-SDi camera would be cheaper than an analog camera (negating the cost of the higher res sensor ofcourse) because a HD-SDi camera does not need a digital to analog converter.

The reason it hasn't got the volume yet is the pace at which analog prices dropped, making the jump to HD greater and less appealing but IMO it will happen.

Something needs to record IP cameras as well doesn't it?

If you want to use an existing IT infrastructure, software doesn't come for free

I might be wrong but I don't think so. Sometimes, but not quite often. Not yet. Give it 3-5 years

I think you are too harsh. They may be too lazy to learn new stuff, though

It's irrelevant here.

I do not want to secure my premises at this stage, I want to test available configuration, settings, networking.

Everything will be installed inside/outside my garage, temp. mounting points etc. 

 

 

Besides, the only thing HD-SDi is missing is volume,

 

HD-SDI missing upgrade options.

In theory IP has no limit to resolution in future

Then is not CCTV you wish to learn, why understand what WDR stands for but not interested in why or where it's used? Just trying to understand what exactly you are looking to learn, I'll explain the abbreviations very quickly if that's all your looking for.

In theory, possibly but IP has limits mainly that are based on your existing infrastructure when it comes to upgrades but yes more leeway than HD-SDi but remember IP had been around in security for 15 years iirc.

IMO HD-SDi Vs IP is a pointless argument, they have very little in common, if you need what IP can offer, you need IP! HD-SDi is competition for analog not IP, comparing analog to HD-SDi and HD-SDi has many benefits.
