Question about 2005 Toyota Corolla
Alarm goes off several times during the night, but only when it is cold (low 30's in SoCa).
When batteries get cold they loose voltage.
The car alarm probably thinks someone is tampering with the vehicle.
Check car battery and alarm backup battery for poor functionality and replace.

I have just had my Toyota Dealer solve this very same problem. I purchased a 2003 Toyota Camry second hand. A great car, except for the car alarm going off when the temperature dropped outside at night. Neighbours were not impressed. The problem was in a electrical relay that talks to the 'Body Control Module' (grrrr.... computers in cars). This is part of the car electrics that controls things like 'auto lights off' when you lock the car, 'power windows' after you switch off the ignition, 'central locking' and a few other important things like 'interior light auto off' (so you don't flatten your battery if you accidently leave it on). The faulty relay cost me $450 to replace, including labour, but everything works great now and most importantly, no car alarm at night. I cannot guarantee that yours is the same problem but my best advice is to take the to a Toyota dealership and get one of their mechanics to test it properly (they plug your car into a test piece of equipment that can check it properly). Shouldn't cost you any more than $100 to find the fault and to get a quote to get it fixed properly with a guarantee.

you can get a replacement at your local Toyota dealer.But in the me time you can remove the fuse to disable your alarm.Some vehicles have the fuse mounted in the engine compartment and some are inside the car.Look in the owner manual for exact fuse and location.If you need more info write back and I will further assist you Thank you.

1994 Toyota Camry is not equipped by the manufacturer with an alarm system. The only suggestion I have is to remove the aftermaket stuff from your vehicle.

No there is no such adjustment. The system has a faulty part, likely a door latch anti tamper switch that is affected by the cool temperatures at night. You will need to contact the dealer for testing and diagnosis
