1. Residential Security Cameras What is Legal?If you are installing a video surveillance system to monitor your home, it can be difficult to place the cameras legally. As a general rule, monitoring someone without their knowledge or consent is illegal when they are in an area that provides a reasonable expectation of privacy. This includes but may not be limited to bathrooms, bedrooms or changing rooms. It may also be illegal to record video or audio in public areas without a sign designating that you are doing so. These laws vary by state, so be sure you're familiar with the laws regarding covert video recording in your state.

Even if humans aren’t home, the sounds of the dogs barking could alert neighbors and the entire neighborhood of a problem. Simply having a “Beware of dog” sign could send a burglar on his way. They sound false alarms Dogs, however,… Read moreIt’s only natural to feel like your safety is compromised while your home is being gutted for renovations. Ironically, the construction your home is undergoing might even enhance its security, like the addition of a carport that conceals high end vehicles or a guest house that doubles as a storage unit for valuables. But the process of making these changes can cause inherent safety risks. Your walls are being torn down and your property is being swarmed with strangers each day. That’s why adding security cameras during construction, or re positioning your current ones to monitor the work area, can be very helpful. Here are 7 reasons you should use surveillance cameras during construction. Finding safety issues Reviewing the surveillance footage from the construction area can help you identify safety weak points caused by the work. If there is a massive hole in the wall facing the street, that can be an enticing entryway for potential burglars. Ask workers to cover this hole up at the end of each day, and arm that area with extra motion sensor alarms and lights.

The row of IR illuminators 1105 provide adequate illumination without producing a bright red/visible glow that would result from fewer and more powerful IR illuminators. In some implementations, the lens assembly 704 is supported by a lens holder 1120 within the device housing 702, and the lens holder 1120 has a top edge raised towards the front cover plate 708 for blocking the infrared light generated by the array of IR illuminators 1105 from entering the lens assembly 704 directly. In some implementations, the IR illuminators 1105 include IR LEDs having a wavelength of 940 nanometers. In some implementations, the IR illuminators 1105 include IR LEDs having a wavelength of 850 nanometers. In some implementations, the image sensor for the doorbell camera 106 is less sensitive to 940 nm light than it is to 850 nm light. Therefore, IR LEDs having a 940 nm wavelength cause less interference with the image sensor than IR LEDs having an 850 nm wavelength.
