best security system for business
However, how far out do you really need to see, if the main goal is just to pick up who is at the front door, or who is coming up to the house?Personally, I was very satisfied at
this level of performance. I will also say that I think this camera probably is a much better option to use at ground level. For my next test, I installed this near a second floor window at several different angles. Of course, seeing the window was fine. However, who would put such a camera on the second floor and then just simply aim it at the window?After all, if a criminal is desperate enough to try and get in
through the second floor window, they will probably find a way to do it. But, then again, what kind of stupid criminal would bring a 20 foot ladder with them for this purpose?Or even try this method of entry, when they could do the same thing on the first floor?The night vision feature is also very good. Personally, after having reviewed a number of these cameras, I now think that night vision of some type should really be a requirement. After all, if the camera cannot take an accurate and viewable picture after dark, what good is it?Do you really think that a burglar will come in broad daylight and leave their calling card?I think not!This model has 36 infrared LED lights that provide the night vision ability. I had no trouble seeing anything even in the dead of darkest night. Actually, the viewable range was at least as good at night as it was during the day. I could see faces very clearly up to about 25 feet.

Its feature lineup includes a night
mode that prevents low battery chirps from disturbing your sleep and a humidity sensor that helps the unit tell the difference between smoke and a steamy shower. It forms a network with other Nest Protect units, and can pass information on regarding the location and nature of a detected hazard. It also can communicate with other Nest products, such as the Nest Learning Thermostat Est. $230 for example, to turn off your heating system if CO or smoke is detected. In terms of core performance, most reviewers give Nest Protect a thumbs up. It has only a photoelectric sensor, which normally will mean that it is more effective in detecting smoldering fires rather than fast burning ones and that's exactly the performance that
Consumer Reports found when it tested the first generation model. However, the current, second generation Nest has a unique Split Spectrum sensor that's said to be more effective than the norm for photoelectric technology. However, we did not spot any rigorous testing to verify that claim, so for now, consider this to be a standard photoelectric unit. Likewise, expert testing of the CO side of things is limited. No one has rigorously tested the CO detector performance of the second generation model. Consumer Reports says that the first generation Nest Protect worked well as a CO detector, though it was more effective in sounding an alarm when it spots high CO concentrations than low.
