Review on BW 2.4G Wireless Color Video Transmitter and 📹 Receiver: Ideal for Vehicle Backup & Front Car Cameras by Christopher Gonzalez

TL;DR: Yahoo! TO BUY! Otherwise let me entertain you. Last year I fenced my property with a 6 foot high fence that you can't see at all. Our driveway runs between a fence and a small outbuilding into an alleyway behind our house, leaving us with a completely blind alleyway entrance. The problem is compounded by the fact that I have a big pickup and have to reverse - I really have no idea what's going on in the alley. And of course there are a few pranksters who happen to be wandering up and down the alley at a ridiculous speed. The problem was asking for a solution before my truck, which I really like, got a serious hit. I already had a reversing camera and a monitor with two inputs (one input is not used), so here's what I did: I installed two cameras on the side of the outhouse, parallel to the alley, one in each direction. I gave this to an inexpensive video combiner also purchased here from Revain (VideoSecu Office Home Security Camera CCTV Color Surveillance Video Quad Splitter Processor 1EY) which I set to dual split mode combining two cameras in a frame with two stretched images redirects. perpendicular to each other. By the way, it looks decent on a widescreen monitor, if admittedly a bit distorted. This, in turn, I built into the product, a 2.4 GHz transmitter mounted at about head height on the inside of the wooden wall right next to my driveway. Then I installed the receiver in the truck, high up in the back of the cab. I fed the resulting video into a previously unused input on the monitor, made sure the power came from the circuit, which was only heated when the ignition was on, and the installation was complete. Every time I reverse even near the house I parked in, I can see the lane up and down before I even poke an inch of the truck's body out there. My risk of being crushed went from rolling the dice to zero in one round. Just imagine the difference in stress. Did I mention that I really like my truck? So. We also have another vehicle, a car which is usually driven by the lady of the house. I thought it would be nice if she could see what's going on too, although she gets out the front of the car and still sees a bit. So I bought her the same monitor as mine, bought a second 2.4GHz Rx/TX module from this site and installed the receiver in her car. I took the risk that only one channel was involved (so that the 2nd receiver also hears the first transmitter) but it turned out to be the case. So now she can see what's going on too, and our risk is reduced again. I saved the second channel as a backup. I then bought a third set to have an RF monitor in the shed for when I'm tinkering around in there, and tucked the transmitter back in as a spare for spare, so to speak. The only thing that didn't go perfectly was that in her car I had to mount the receiver low and under the dash as she really didn't want wires wired everywhere and I wasn't willing to do headliner surgery. This puts a lot of metal between the receiver and the desired signal, and in fact the signal in your car is not very strong. I'm thinking more of taking a small mini coax and hacking into the antenna on the windshield. I'll update this part of the review when I get around to it. Let me be clear: I believe this problem is in no way a malfunction of the Rx/Tx units, it is simply a problem caused by the receiver being set low. and next to all that metal. Fur. I would like to see slightly thicker cables for the power supply. These wires are thin! Speaking of the power supply, what I used in the annex was a 2.5A in-line power supply that powered the cameras, switch/combiner, shed receiver and transmitter. I'm a radio amateur (ham radio) and really can't stand all the RF noise that typical cheap switching power supplies like the ones that come with security cameras generate during normal operation. So the 2.5A linear power supply handles it all with ease, and there's no RF noise at all. I could not detect any excessive heating on either the three receivers or the transmitter. A little warmth, that's all. Reception (and therefore transmission) is extremely stable and reliable, and signal quality is perfect when within a reasonable range for my application, which is about 20 feet in either direction. I'm using an old CRT video monitor along with a receiver in a shed; However, I rarely have to turn it on. A word to the wise: note that since the devices get a little warm, they know they're using several watts of power even without metering. You really only want to connect them to the +13.8VDC circuits, which are only active when your car is running and the alternator is producing charging current. Otherwise you risk starting your engine after a few days of inactivity and. Nothing. Dead battery. I hate when that happens. I don't think you'll like it either. Either way, these are great, flexible products that can really increase security for you and your loved ones, and I highly recommend thinking about what else you can do other than building a backup camera. wireless, especially since it's pretty easy to connect a video cable for this app. This combiner I mentioned can make a four chamber quad combine and you can feed it to the transmitter. Four cameras, all displayed simultaneously via a monitor input. Do you have any ideas? Hooray!
