ELAN, the home control brand of Nortek Security & Control (NSC), announces a range of surveillance cameras, an NVR and a selection of compatible accessories are on show at ISE 2020.

The range features built-in advanced IntelliVision analytics, allowing for more precise person and vehicle classification, as well as personalised information alerts to homeowners. Deep software integration allows for a single security system complete with advanced privacy features.

The August smart lock collection gets an update at CES 2020-- the Wifi Smart Lock features a design by co-founder Yves Béhar 45% smaller in volume and 20% slimmer than the Smart Lock Pro, plus a number of "key new design changes."

Available in either matte black or silver finishes, the smart lock update carries built-in wifi, meaning it does need pairing with an August Connect hub. The result, the company says, is an instant connected upgrade for any front door. Setup should be simple, since users simply need to pair it with the August Connect companion app providing remote access management.

Legrand-owned smart home company Netatmo takes on connected security at CES 2020 with the imaginatively named Smart Door Lock and Keys-- a home security system replacing the regular key with an NFC-based Smart Key.

Customers can install the Smart Door Lock as a replacement to any cylinder door lock. It does not use wifi, meaning it cannot connect to the internet. Instead, connectivity is based wholly on Bluetooth, and key data is stored on the lock itself, making it more secure against electronic attacks. In fact, Netatmo claims the lock has three certifications against both physical and electronic attacks, A2P*, BZ+ and SKG***. Powering the lock is a battery supposed to last for two years before replacement is required.

Connected security product maker Wyze announces a take on the smart lock-- the Wyze Lock, a wifi- and Bluetooth-connected lock customers can use with existing cylinder deadbolts, making it easier to install.

Compatible with most, if not all, cylinder deadbolt locks, the Wyze Lock requires connection with the included Wyze Lock Gateway wifi bridge for remote door locking and unlocking via companion Wyze app. In case the wifi is dead, Bluetooth connectivity allows customers to open the door via smartphone and Bluetooth, and in any case the door retains the regular key.
