Same issue on our farm. No power at the gate/camera end. Sending video over large distance is power-limiting. Ping to monitor for reference.
you can do a wired system, you need a amp for your system, some systems can’t do it.
We wired up systems with miles of cable, these were commercial systems though. You might not be able to afford a new commercial one as the camera alone can set you back 800 but you can pick up a used one. The commercial cameras have features like night vision and automatic adjustment for headlights. You can read a license plate even if they have their headlights on your camera.
there are residential systems with the range with an amp, but the cameras aren’t very good.
I use 2 raccoons with walkie-talkies. Works great as long as there is dog food in their tray.
How far is the distance? Cause there are ways to do this, sometimes including solar and 900mhz transmitter. It can be done, just not cheaply
Power over Ethernet (POE). That far you made need to step it up with a powered coupler.
Perhaps a camera with along optical zoom nearer the house.
IIRC POE, power over ethernet is good for ~100 meters.
Add an IR illuminator near the gate.
If you need to record, get an NVR (not DVR). It uses cameras which run off of CAT5 wire with network connectors. You’ll still have to run the wire, but you should be OK with power requirements for the cameras.

Sink a weather proof battery box underground with a deep cycle battery, run a line to the camera location. Disguise the battery box using local material, rocks etc. Have a charged up one on standby and swap it out once a month or so with a fresh charged one. Solar cell to charge comes to mind but not as easy to conceal
you need to purchase bnc wire that includes power in the wire bundle its not cheap but it allows you to hardwire a camera and comms to your gate. RG 6 or RG 59
That should be well within the range of Coax with the right camera setup.
I assume you are doing this old-school with coax and NTSC signals. I do not have the details here, but there was a great device which used to do this, and used to be stocked by the company supercircuits, though I do not think they still carry this.
Find them on google and call them up and ask if they remember the device that had variable power supply, and two units, a sender and a receiver, each about an inch and a half square, and a half inch thick. The sender had an input for the camera, a microphone input, and a power output which could be split to support both a camera and a mic. It plugged into a single run of coax which would both send power out to the camera, and then run the video and audio signals back to the receiver unit, IIRC up to 1500 feet. The receiver had the input for the coax run, a Camera signal output, a mic signal output, and a plug which took power from an included variable power supply which could be dialed up to 18 or 21 volts or so, to add oomph to overcome voltage drop.
It was great, but eventually lost favor as IP cameras came online. No idea if it is still made, but Supercircuits might know a name and model number, and you might find it online. Or Supercircuits might know if a new thing you could use.
Actually, I found an old brochure. Hit google and see if you can find it:
Check out ubiquiti networks unifi wifi and cameras. If you can get power out there, you can create a wireless link back to your network. You can run their camera off of the receiver end. I do this to my barn which is 1200’ away from the house.
Cheap solution:
I have been running the following for 4-5 years:
-Old Dell Optiplex 980 (Free found in basement, monitors 4 cams)
-Linux (Free open source)
-“Motion” software (includes motion detection, internet
exposure, command configurations, clip file control, cgi, etc) (Free open source for Linux)
-Existing WiFi system (Free (6-7 yrs old)
-Foreign-made I.P., IR cam (Sricam, $18 on Amazon 4 yrs ago)
-Existing A.C. line (Free, installed for gate opener)
-Unobstructed line of sight between camera antenna and WiFi router in attic provides reliable comm for 300 feet using camera’s antenna (see notes).
Notes:
-Cheap or homemade (see Google,YouTube) directional antenna could extend comm to 700 feet.
-Powerline Ethernet Adapters advertise 900 foot capabilities. (around $50 on Amazon)
-If no AC consider solar.
-I also successfully run two Faleemi cams $25 each and an old usb camera (Free, laying around).
-The cheap cameras are not easy to install, definitely not Plug and Play. But once working, they keep working. I could answer some of your questions. The “Motion” software, also, takes a little effort but does everything the expensive monitor software does. You should have basic skills in Linux. You should also know a little about your Wifi router, e.g. how to create static I.P.s.
-This setup is definitely not secure but running on Linux is a plus in that department. If you don’t want to expose the stream to the internet you can run the whole thing inside your private Wifi with local I.P.s by disabling the internet stream in the software.
