currently the signal stops at my garage door.
all I want to be able to do is receive a clear signal in my garage.

... some fourty years ago we made 'enhanced' remote connections with inserting the emitters and receivers in tin-cans and directing them on each other.
So we got radio links with antennas, that normally transmits only up to 2 kilometers, to stable connections between towers and skyscrapers with distances of >30 kilometers ;-)#

Are there in your garage metal covering, roof or wall?

You need a passive repeater -2 antennas connected by a short cable. 1st inside garage, 2nd outside. Hi gain antenna may not help you in your case
Also you can buy a cheap wireless router, install it on the garage wall and run in repeater mode
once again no idea what your talking about, got a link

Outside antenna with cable and SMA male connector
Inside antenna
SMA plug
Tool for wall drilling
You just install 1st antenna outside your garage, 2nd inside and connect them using an SMA adapter

so leave the camera/transmitter alone
many thanks for the advice ill give it ago

Hey Andy
Initially I was suggesting to use something like these
https://www.sparkfun.com/products/9145
https://www.sparkfun.com/products/558
But in your following comments and diagram this would not work, from your diagram the signal needs to go through three wall, one is metal and I'd assume the others are brick
What Bbe has suggested would be the easiest option, however I would use a not-so high gain Yagi for the external antenna as these are very directional (like 7 degrees coverage) as opposed to the panel antenna (around 30 degrees)
Also the inside panel antenna that Bbe linked to is a 5.8Ghz antenna so don't buy that one!
For the external, I'd go with (in order of gain):

For internal:

One thing to note is that this camera is not Ethernet (Networkable) and is just an analogue 2.4Ghz, this means that it will most likely consume 100% duty cycle of the RF space for the frequency space it uses, this may intern create interference for other wireless networks including your own. Some of these cameras are just plain nasty in there design and don't adhere to wireless Ethernet channel spacing.
This also means that network based RF extenders will not work
This is the reasoning behind the lower gain Yagi in place of the panel, the energy is more focused to the receiver and as it's focused you don't need as much gain, unfortunately this is going to be a suck-it-and-see exercise to find your best option in antennas
One other thing to note is that depending on where the "big metal door" is (assuming that it is a garage door) this maybe needed at the receiver end as opposed to the transmitter end (or maybe both ends)
