Hello friends! I need cover the entrance to a ranch with an IP camera which would be located about 400 meters from the main gate. Can anybody suggest me the best camera (no PTZ) for this??? Thanks in advance. BR.

Hi Gaspar,
1) The camera will be 400M away from the gate which it is watching over.
Q1: How much details do you need? Do you need enough to ID someone at the gate?
Q2: Can you place the camera closer to the gate?

Hi @Gaspar
See the Dahua Q3 catalog pages 62-65
Dahua Q3 Catalog for the IP Video Product 201808
This gives you some idea of what Dahua claims for DORI distances.
Personally I think they are being optimistic, for example we typically use 100 ppf ( pixel per foot ) for a guide to determine ID distance, and Dahua iirc uses about 75 ppf
Thus I would expect better performance if you take their DORI numbers and cut the range by 25-33%
At 400M I think you will need to look at the various PTZ models that have better optical zoom.

no power at all...but there is a light pole by the gate (owned by the Electric Company) and maybe I can get current from it so, what if I can???

maybe I can get the camera closer to the gate (solving the power issue) but what about ethernet cable??? is a very long distance...
Instead of the long Ethernet cable, if you have line of sight you could install a Layer 2 Transparent Bridge with a couple of Ubiquiti 5GHz radios, like this below:
thank you very much @TonyR, I was thinking something like that...but here´s the thing: if I can get the camera close to the gate then the distance between it and the NVR is about 1.1 Km (with LOS) so my question is: instead of the PtP link can I use a wireless camera (maybe Hikvision) and a sector antenna with an Ubiquiti radio in the NVR´s side???
how about a solar panel and battery pack as power source for your cam and the wireless backhaul device? a decent U1 battery (think wheelchair-size) is good for 30Ah. If you figure 5w for the cam and 5w for the backhaul, at 12V that's 0.833A x 24hrs = 20ah. Assuming you get 4hrs of sunlight (of full rated output) per day, a 5A panel and a decent charge controller should do the trick. those are very off-the-cuff and conservative numbers, just to get the idea. Of course, you'll need a good PTZ at the house to keep an eye on the equipment down by the gate. ha!
PS: or maybe just a long outdoor-rated extension cord and PLA adapters?
where did that 1.1km come from? i thought you said 400m...

Short answer:
Most likely "No."
The reason:
The radio built-in into wireless cams has nowhere near the transmitter power and receiver sensitivity that the UBNT radios (and radios of it's type) do. You might get a cam to "hear" the UBNT and "talk back" to the UBNT but the UBNT will likely NOT hear the cam from that distance due to the cam's low power.
EDIT 1/9 0722 CT: Additionally, when 2 UBNT radios are set up as a Layer 2 Transparent Bridge using their proprietary communication protocol, it functions as close as you can get to a Ethernet cable without the cable. If one of the devices is NOT a compatible UBNT product, you won't get that function and its advantages.

I'd likely go with it's "non-Loco" bigger brother. The latest one is NS‑5AC.
Why not just run fibre optics stability and introduce media converters at both ends
I see this a reliable, long lasting solution as opposed to Radios
Oh, fiber's great! But I doubt the OP wants to put in over 1 Km / 3,300 feet of it.
you´re right @TonyR!!!Oh, fiber's great! But I doubt the OP wants to put in over 1 Km / 3,300 feet of it.
Have you considered long term needs.Radio getting fried, wireless issues,need for occasional reboots etc.
For me, hardwiring is my option for any project especially when I know its possible. This reduces my maintenance costs greatly

In many areas with extreme lightning storms (such as where I live in SE U.S.), using a UBNT bridge IS installed to PREVENT those expenses caused by ESD due to nearby lightning strikes. I have replaced dozens of Ethernet ports and motherboards, switches and routers damaged by ESD (Electrostatic Discharge) from nearby lighting strikes. Those devices were connected to Ethernet cables that ran outdoors both underground and overhead.....I highly recommend NOT doing that where I live.
ESD "loves" relatively high impedance CAT-5 cables more than secondary power lines. Not that nearby strikes can't or won't affect power lines but where I live and from what I've seen, when lighting strikes nearby the damage from ESD occurs mostly on phone lines, network cables and analog CCTV (BNC) cables and NOT the secondary (120 /240 volt) power lines.
Again, I'm a big proponent of fiber as it's dielectric properties that make it immune to static, lighting, etc. and provides unequalled speed but long distances are not economically feasible and take quite some time to install.
I have installed a dozen UBNT Layer 2 Transparent bridges between houses and guest houses, shops and barns located from 100 to 800 feet and 5 years and dozens of severe lighting storms later not a single issue. And these cost less than $200 to install and can be installed and operational in less than 6 hours.
That's why I use them and will continue to do so unless they are not economically, technically or strategically viable for a specific job.
FWIW, I have had to reboot PC's, modems and even switches from time to time but can only recall rebooting a UBNT bridge on one occasion.
ok, having cogitated a bit on the original question, how about a decent PTZ? I know you mentioned, "no PTZ", but
maybe you only meant to say you don't need to move it once set up? A decent PTZ with 45x zoom should be able to
give you >100PPF at 500m (per IPVM calculator for 2MP cam @150mm focal length.) You'd have to mount that sucker to
something real solid tho... Anyways, this could do it, perhaps:

and i still don't understand where the 1.1km came from when the OP was regarding ~400M...
