Four-Camera Wireless Kit for Home Monitoring

The KEHIPI B8-4 pack includes four rechargeable battery-powered bullet cameras and a base station with built-in storage. Each unit captures 2K resolution video across a 110° viewing angle and connects to 2.4 GHz Wifi via Bluetooth-assisted pairing through the O-KAM app. IP65 weatherproofing allows permanent outdoor mounting.

Upgrade from Wired DVR Systems

This kit replaces multi-cable installations that require drilling and mains power at every camera location. The wire-free design suits renters or owners who cannot run cables through walls. The jump is worth it when you need flexible placement up to 50 feet from the hub and prefer battery maintenance over trenching conduit.

Limits of the 2.4 GHz Interface

The system operates exclusively on 2.4 GHz Wifi, so it will not join 5 GHz networks and may contend with other devices on the same band. Local recording relies on a micro SD card up to 128 GB or a paid cloud subscription; there is no onboard hard drive despite the specification flag. Bluetooth is used only for initial setup, not for continuous streaming.

Questions about this item

What size mounting area does each 4.37 L x 2.91 W x 5.2 H inch camera need?

Each bullet camera measures 4.37 L x 2.91 W x 5.2 H inches and weighs 1.601 kg, so a flat surface with at least that footprint and a secure screw anchor is required.

How do I pair the cameras to 2.4 GHz Wi-Fi using Bluetooth and the O-KAM app?

Enable Bluetooth on your phone, open the O-KAM app, and it will automatically discover each camera; follow the in-app prompts to connect them to your 2.4 GHz network.

When will I need to recharge the 5000 mAh battery or replace the micro SD card?

The 5000 mAh battery lasts 2-3 months per charge; micro SD cards up to 128 GB store motion clips and should be swapped when full or if recording stops.
