Question: does this plug in to a wall socket or use batteries? can it be hard wired?
Document: It takes so much effort to get it to work consistantly, it's not woth it. If you plan to use it hard wired it might be easier.
I can't tell if it works: setup is well beyond my capability. The booklet instructions don't offer a handle - they assume too much and are confusing. I bought this to give my iCam a second camera. ICam set up is a two on an easy to hard scale of 10. This is in unimaginable territory. I sent it back by UPS -- there's no Amazon drop box convenience on this item.
Camera is easy to setup and easy to use. Seems to be good quality for the money. Overall a great value and I am pleased with this purchase.
Difficult to setup and doesn't work with all routers. However if you do manage to set it up and have a router that works with it, it works great. Clear picture but you have to pay for software if you want to make use of the mic feature.
Got this camera for home surveillance and spying on our pet cat and dog while we are out of the apartment. I wasn't sure how often we would use it but since my boyfriend and I downloaded the mobile app it has provided both peace of mind and night vision camera pet shenanigan entertainment. Great purchase.
This is a really cool little camera. I was able to quickly set it up to work with my local wifi network, the picture is good, and the ability to steer the camera in every direction (using the computer) is awesome. However, when I tried to set it up so the picture can be viewed via the Internet from any computer, the set-up failed. The Tenvis installation &#34;port forwarding&#34; procedure is designed to work with about 8 brands of router; if you don't use one of those brands, then you are stuck.
Look I even had the very first one outside over winter(AGAIN VERY BAD DECISON! they are not meant for such low temperatures or conditions but I think this shows tenvis cameras are built pretty dang well) and it's the one that still works just doesn't have wifi capabilities lol. The pictures on my devices(laptop, samsung galaxy tab 2 7.0, samsung galaxy exhibit 4g, samsung galaxy s3) are nothing short of incredible. Pan tilt are an absolute necessity for what I use these cams for and once again flawless operation.
For instance browsing the web on my tablet, I can also be listening to the surroundings of where the camera in question is placed so this way I don't need to keep checking on the cam if I hear something on the audio i simply switch over to the app I view the cams with(I won't mention the cam viewer &#60;ahem&#62; I personally use and have found to be best) my cam viewer app and check things out. All in all for the price you really can't go wrong... it was like this, I was going to go buy motion lights for my new residence because of having some prowling problems but all the lights I could find were as much as one of these cams  and lets face it I'd be dumb not to have made this decision again.
would consider buying a few more for home security without having to pay an alarm company.
this will be my 3rd and 4th cameras from tenvis. the first two one still works and the other is kind of in a coma BUT that is due ENTIRELY to ME!!! I was tinkering with making a completely self sustained remote wireless type system and fried the boards. Well to be honest these suckers are pretty resilient because the one I only fried the wifi but the other is in a coma of sorts. At any rate up until the point of my messing with them(obviously voiding all and any warranty and I in no way recommend following my example) they worked FLAWLESSLY!
Answer: It has an AC adapter and can be wireless or wired.
