turret vs bullet

A G · 4 Sep 2023 at 14:29

hello,

Hopefully someone can advise, I had an installer come to asses a property I need cctv's installed at, and I wanted a camera quiet high up, at the eves part of the house - and ideally be able to see the driveway and road
The installer claimed, the turret Hikvision cameras I have will not be suitable and I should purchase 1 bullet camera if I insist in having it that high up, he claimed it would only show the head of someone if its a turret camera but a bullet camera would be better. I'm unsure if it actually makes a difference, I already have the turret Hikvision cameras purchased, and although I can return one, curious if what the installer said is valid?

If you mount them on the eaves, assuming a two storey house, then you're not going to capture anyone's face regardless of the camera you pick.

Yes, I thought the same, but curious why the bullet camera would make any difference as the installer claimed?

At a guess it might be down to the different focal lengths available, a camera on the eaves with a wide angle lens on it isn't really going to help much unless the intent is to just capture an overview of an area and you have other cameras for getting details.

Yes, there is another camera, covering 1 side of the house the installer claimed, I needed another camera to cover another angle, the intention was do the wiring through the eaves, so there are no wires showing. And the only way to ensure no wires show, is having this final camera installed at the eaves level.
I was curious on the turret vs bullet if both are 2.8mm, does it actually make a difference on the viewing

I can't see how it would - maybe the turret can't tilt down as far as is needed?

If it helps these are the 2 cameras:

Turret: DS-2CE72KF0T-FS(2.8MM)-BLACK

Bullet: DS-2CE12KF0T-FS

But yes I couldn't understand how 1 would be better than the other from a viewing perspective, but thought I'd check with more knowledge peeps here

The only difference between the two linked cameras is the form factor. It may be that the installer just wants the camera lens to extend out a bit further to clear an obstruction and then it would be valid to quote for a bullet rather than a turret. Other than that, I don’t see it.

Is it definitely that camera he has suggested? There are other Hikvision models that only come in 6mm in bullet form but those are 2.8mm/3.6mm so if it’s those ones they’re pretty much the same. He may just prefer to mount bullets. They’re generally easier to point than turrets.

With the cameras suggested, this would also be correct. For optimum face capture you want them at 2m but then everyone can grab them so 3.4-4m is more common. If you want a decent face image then I would go for a longer focal length camera - 6mm - or a smart zoom that changes it’s focal length when motion is detected in specific areas (zoom in when motion detected at the gate, zoom out when motion detected elsewhere else in front of the house.

Hi

Nope it wasn't the installer who suggested it, although he did say get 2.8mm lense but in bullet, so that's the one I could find through COP.

I didn't see any 6mm but I guess I wasn't looking, with regards to the smart zoom, is that just a feature of only certain cameras?

I'll need to browse some sites I've got access to, to see if I can locate one

6mm is usually special order in the UK. If you have an account with COP they’ll get you whatever you need. They’re also really good on the phone so it’s always worth ringing them and asking.

https://www.cop-eu.com/cameras/ip-cameras/DS-2CD2647G2HT-LIZS(2.8-12)(EF has EPTZ and auto tracking which is what you want to do smart zoom on Hikvision.

I would say Turrets are more discreet than bullet cameras, if both are 2.8mm I would say No.

Thanks, just realised this is an IP camera, I have coaxial RG59 2 core running - although now I am curious, as for these camera being placed at the eaves location, I will need to run a new cable, if I can use a CAT6 with my current DVR then I can explore an IP camera, per your suggestion.

I have 4 cameras which will be using the RG59 cables with, is it worth sharing which DVR I have, or can you simply not mix and match IP Cameras with the cameras I have under 1 DVR?

This is the DVR I have:
IDS-7208HTHI-M2-S(C)-2T TVI DVR 8CH 8MP Acusense 2TB

I have a Hikvision Poe bullet camera, I'm happy with it.
I think I put it about 2m up.
I've had a camera up about 8/9 years in total and never needed them so I'm not sure why I bothered, but then again, you never know.
I periodically log on to it to make sure it's doing its job and check the SD card is still ok.

Hi

COP have come back and said they have "4mm fixed lens if this helps at all?"

Would that be any too much of a compromise from a 6mm as you suggested?

What is it you want to see? Faces at the gate? Then get a zoom camera or buy two cameras. One to do the faces and one to do the general area coverage.

6mm ColorVu cameras are available - https://ssrtrading.co.uk/hikvision-...-colour-ip67-130db-wdr-tvi-ahd-turret-camera/

Like most people have said it’s not admit to mount a camera up too high simply for what it is recording, however there is a trade off to have it mounted up high enough out of the reach of the individuals in question but low enough to get a good picture!
