Security ip camera

[Taff]

We’ve put provision in for 2 camera’s with network cable, front and back of house. Looking for any ideas on type that provide power through cat 5. 

 

Is is it worth it?

or should we just plan for wifi cameras?

Go poe - much more reliable . Hikvision always seem good . 

[PeterW]

Lots of decent POE cameras out there, only issue is getting the cable properly terminated as punch downs etc at height are no fun. Look at HikVision

I've reolink WiFi cameras all over the site. Work just fine and not too expensive. I don't see the point in anything that needs a network cable.

WiFi bandwidth is limited . Not just by your cameras but everything Wi-Fi is sharing it . Common limit is 54mbps . Poe cable will be limited by isp throughput and the tariff you are on .

Does that mean if I only get 38mbps that WiFi would be ok?

[PeterW]

With PoE you get it all on one cable anyway so if you’ve got to run power then it’s as easy to either run power or Cat5.

So how much bandwidth does your security camera actually need then?

 

I can stream boradcast tv over 3mbps so I would not expect a security camera to use even as much as that?

Depends on resolution , bits per pixel . MPEG compression, FPS .

It could all by fine but you only have so much Wi-Fi available . Also if some Wi-Fi is 5ghz range and some the older 2.4ghz  they can run simultaneously with the correct router . Also if you / others are using Wi-Fi for browsing / streaming it all adds up . As @PeterW said you’ve got to get power to the camera anyway so make it poe -then Wi-Fi is ‘free’ for other uses . Need a router that supports poe of course - there are different poe standards aswell ?

[PeterW]

Just 2 cameras I would be inclined to just use injectors next to the router and be done with it.

True . But if he wants to add more at a later date ... 

[PeterW]

Yep agree but a lot of the cameras come with the injector. Can always change to a 4 port PoE switch at a later date. 

[Taff]

Great advice people I will have a look at the suggestions in the morning ?

I've been using IP cameras with passive 'poor mans' PoE injectors/splitters (i.e. they use the same unused Ethernet pairs but that's as far as compliance with the standards goes) for over 15 years now and never had a single issue. I'm sure there must be downsides but if like me you want full market choice of camera and get maximum bang for buck I'd recommend it.

 

I'd suggest WiFi for mobile devices (or very hard to reach places) and wired connections for everything else.

You can use normal analogue HD cameras with baluns on the cat 5 cable and go old school, get a DVR 1TB hard disk away you go

 

old skool rulz 

[PeterW]

Using Cat5 for analogue doesn’t make sense unless you have local power at the camera. You still need two cables to the camera. PoE is now pretty standard and IP cameras are significantly better than analogue. 

[Taff]

The cable has already been installed to the site of the camera’s, so Poe is just 1 cable that can power the unit as well? Soz for being thick ? also do Poe cameras have the ability for an app over Wi-fi?

[Taff]

We choose cable option as didn’t want to steal from the Wi-fi!

Minimal I would presume as hopefully not used much

The 4 pairs in the cat 5 are split,

3 do power 1 pair does data.

that’s what industry has done for decades.

 

So the cat 5 can do IP based camera or analogue HD.  That’s what I have , happy with 1080p resolution.

anyone have experience with the reolink rlc 520

Some sources suggest that slow wifi devices will slow down the access point for other users. If that's true avoid wireless cams at the range limit.

An advantage of cable is that it can't be jammed.  It wouldn't be difficult to jam a WiFi signal by burglars who go equipped to do so.
