The ALS assembly 714 optionally
includes a light pipe to direct light entering the lens assembly 704 to an ALS and ALS interface circuit that are optionally located with a distance from the lens assembly 704. In some implementations, the front cover plate 708 is substantially opaque except the button opening 710, the microphone aperture 716, and the camera opening or transparent area 712. In some implementations, the front cover plate 708 includes a substantially opaque area that is distinct from the button opening 710, the microphone aperture 716 and the camera opening or transparent area 712. The microphone 1104 is optionally concealed under the substantially opaque area. Further, in some implementations, an array of IR illuminators 1105 are disposed under the substantially opaque area of the front cover plate 708 and configured to illuminate a field of view of the lens assembly 704 with infrared light in a night mode. In an example, the array of IR illuminators 1105 include a number of e. g. , twelve LEDs arranged in a row. 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.

54. ”Steve Schmit, engineering manager – alarm certificate services with UL’s Building and Life Safety Technologies division, Northbrook, Ill. , also notes this trend. “We are seeing the
industry approach the market with services. Technology is such that users can interact with the security
system in ways that weren’t possible before, which opens up all kinds of opportunities. We see folks not only introducing new security type services such as video, but that same pipeline enables your security system to help out with things like personal emergency response and home automation sorts of things.

The cost of home security
systems depends on the equipment, plan, installation and more. Most of these costs include home security equipment such as security cameras, video doorbells and sensors. Your monthly home security cost can also include 24/7 professional monitoring services, security camera footage cloud storage and the ability to
control your home security system using your security provider’s mobile app. You’ll be able to easily manage your smart lights, thermostat and other home security gadgets. With all of these features, it is easy to wonder, how much is this really going to cost?Today, the average monthly cost for home security monitoring services ranges from $15/month to $35/month. for a plan with additional features and equipment. Monitored home security systems come with professional monitoring services to watch over your home 24/7 to alert you and emergency responders if a sensor is triggered to help protect your valuables from burglaries, fire and smoke detection. The lowest basic ADT plan includes professional monitoring costs $28. 99/mo. It all depends on your home’s security needs. But bear in mind that if danger is detected, professional monitoring services will contact you first if a sensor is triggered.
