Is there any brand / model of security camera that has no cords ?




darin s


I am trying to find out if there is any security camera that has no cords ( neither video or power ) @ all to it. I know that there are a lot of security cameras that you do not need to run a video cable but I am trying to find one that there is no need to run a video cable or a power cable ? Do they make ones that just run off of a battery and a wireless signal ?


Answer
Yes, there are security cameras that are wireless and battery operated. Most of the time they will be sold as "Spy Cameras".

Here is a few examples:

What is the best security camera for night?




Mike


I live out in the country and have been robbed recently. I currently have security cameras, but they are not the best of quality. I have a 4 channel DVR from Lorex and all the cords are ran already so I would perfer wired cameras. Without spending lots of money, what's the best bang for my buck? I need to see clearly at night about 100 feet. Also too, does having too many lights effect the IR of the camera? Is less or more IR rating of camera better? Thank you.


Answer
This camera is probably one of the best security cameras out there. It has a 65' illumination range, its indoor/outdoor, has 23 LEDs and has high resolution (700 TVL)

The second camera is pretty similiar, same brand and everything, but has a 100' illumination range and 36 LEDs.

The IR switches on when the light around the camera is 0 lux or below. If you leave a light on by the cameras all night they'll never switch over to IR mode, but if it is dark by the camera they should switch over. The light sensitivity or IR rating is how much light there needs to be for the camera to switch modes, the cameras I listed have a sensitivity of 0 lux, which means if there is less light out than a candle would provide, the camera will switch to IR mode.
