What is the depth of field? I am looking for a wireless to mount on a model train and go around the track - seeing what the "engineer" sees.

This is not the product that would for you then. It has a very grainy picture and if the camera is moving it loses video, and it only has a range of about 5 feet. I have two different versions of this device and neither are what I would call solid. But hey if you buy things at a cheap price, you usually get a cheap product.

Hi. I have a British friend I met backpacking on the US west coast. We were on the Pacific Crest Trail, extremely remote and 4 to 7 days between towns. She listened to the BBC every night on a very small radio powered by one AAA cell and having a 4' wire antenna. Whatever it was she used was almost primative and it still functioned very well all the time. She used one ear bud.

You are better off using live view. Why? At f/1.4 the depth of field is razor thin for portraits.

What you want to look for is the gain on the antenna. In most cases, the outdoor antenna will provide between 2 and 3db gain. but you can find higher. Be sure you're looking at an antenna for the right frequency ranges (700 mHz, 800, mHz and 1900 Hz)

Range is good 15 yards line of sight but it is very sensitive to interferiance from wifi Bluetooth etc... Nice toy but impractical... A long cable is much cheaper and more efficient.

Much better than described. I started thinking it must be bluetooth rather than rf. I can use it through walls. Clear line of distance not required in my case as mine is hidden behind subwoofer and easily works from at least four meters (that's 12 ft).

The Trifield does a great job at measure magnetic and electric fields from wired devices. However, it has a lousy RF (wireless microwave) measurement. Try the Acoustimeter or the Acousticom 2 which measure microwave frequencies in the 200MHz to 8 GHz range. It tells you the amount of radiation from cell phones, iPads, wifi, bluetooth, game consoles as well as Smart Meters.

I haven't actually checked the range of the wireless but I installed a wired back up "PYLE" on my truck and with the truck in idle them shaking made it impossible to see.I would try to find a much better brand than PYLE .

It will not work over 3 meters, no matter how I tried. Basically, it is just a wireless display limited to desktop area. Only useful when you have a device without any display output ports and you need to connect to an external screen.

I would not recommend this product. It gives very little distance. I returned my device.

I can put it in my pocket and have excellent reception! It's good for about 20-25 feet. This is an estimate only! Hope it helps.

It detects pretty far out, I have animals 30' away in a pasture and it will often pick their movement up. I don't know about 200' away, would be better if you could mount it closer to the activity. Also, it doesn't pick up 'wide angle' but only straight out in front of the detector. The 1/2 mile transmit claim is valid though!

Yes, that might beyond the edge of possible, actually, due to Z-Wave's typical range being about 300 ft, and this particular device's manufacturer's stated range of "Up to 100 feet line of sight between the Wireless Controller and /or the closest Evolve ReceiverModule"So unless you have a power post every 100 ft between controller and the boat house (where you can install a light or outlet module to function as a repeater), I would not expect this to function particularly well. Z-Wave's 900MHz radio wave and bodies of water don't always behave predictably either. due to some signal dissipation, absorption and reflection... At any rate: I would only give this about a 20-25% chance of functioning without a repearter.

Sorry. I'd like to help you out, but I bought this for my some who lives out of town. I'm not sure what range he gets with it.

There are too many variables to authoritatively answer any questions about the range your installation will get. It seems to be the best short antenna out there. Set it up (for SWR) according to the directions and vary the mount position and you will get the best range available with anything other than a permanent mount 8' whip!

I returned my unit for a refund. The range of any radio will basically depend on the terrain in which you use it. Hilly/mountains etc. about a mile or less. Flat or low-rolling land about 1-3 miles. This radio just didn't perform as I had expected. I bvought a Midland unit which was three times better.

It depends on the distance. This device is nice but will only give you clear image in the range of up to 50 yards. Beyond that things will not be clear and recognizable.
