Home monitoring isn't one purchase for everyone. You may need to breathe new life into a monitor you already own, add a spare camera to a baby setup, cover multiple rooms with new Wi-Fi cameras, or keep an eye on the air you're breathing. The right option depends on what you already have and what you're trying to watch.
The options here span a modest price range, with the least expensive being a used replacement camera for a Motorola baby monitor and the most expensive a new multi-camera indoor Wi-Fi system. Between them sit Xfinity replacement parts and a portable CO2 detector.
Quick take
Need a camera at a lower price? The Motorola replacement camera is the least expensive option here. Want a fresh Wi-Fi system with more coverage? The Sovmiku camera set takes that role. Already own a TCA300 screen? The Xfinity parts can restore it. Concerned about indoor air rather than video? The Cortile detector handles that.

Product notes
Xfinity TCA300 Replacement Parts
This parts set covers the items that tend to wear out or go missing on a TCA300 Xfinity monitor: the battery, charger, back plate, key pad, and desk stand. If you already have the monitor screen, these parts can keep the unit useful without buying a whole new system. The screen itself is not included, so this is not a standalone monitor. The set is used and includes the power supply control alongside the battery. For someone who already owns the TCA300 monitor, this is a targeted, lower-cost way to replace worn accessories. It won't help if you're starting from scratch with no screen.
Motorola Comfort75bU Replacement Camera
This used Motorola camera is the lowest-priced item in this group. It is a replacement camera for the Comfort75bU video baby monitor, with remote pan and scan in the model name. The camera is white, portable, and includes infrared vision and a temperature monitor, so it can serve as a second camera or a replacement in an existing setup. The display type is digital, but this listing is for the camera itself, not the parent unit. If you're missing a camera or want a spare for another room, the price is hard to argue with. Just be aware this is a camera, not a full monitor.
Sovmiku 4-Cam Wi-Fi System
At the top of the price range, this set buys four Sovmiku cameras, making it the broadest coverage option here. Each camera is 3MP with a 360-degree view, and the system records 24/7 through the Vicohome app. You also get motion detection, two-way audio, and a one-touch SOS call. The mount clips into a pre-installed bracket, which simplifies setup. There are limits: it is for indoor use only, not waterproof, SD cards are not included, and cloud storage requires a paid subscription. It also is not compatible with the Hiseeu NVR, so you will use the Vicohome app for viewing. If you want a fresh multi-camera setup rather than a single replacement, this is the complete package.
Cortile Portable CO2 Detector
This Cortile detector takes home monitoring in a different direction: instead of watching for motion or capturing video, it tracks the air. This portable monitor uses an NDIR sensor and gives a 3-in-1 readout of CO2, temperature, and humidity. The display refreshes every two seconds, and the battery is rated for 96 hours of standby. It also has an audible alarm and comes in a green portable housing. It is a single-unit device, so if you need to check more than one spot you may want more than one unit. If your monitoring concern is indoor air quality at home, in an office, or while traveling, this is a useful, compact tool. If you need video, this is not the choice.
Final recommendation by use case
- Need a camera to add to an existing Comfort75bU setup: Motorola replacement camera.
- Have a TCA300 screen and need the accessories refreshed: Xfinity replacement parts.
- Want a new indoor Wi-Fi camera system: Sovmiku Wi-Fi camera system.
- Care about indoor air quality more than video: Cortile portable CO2 detector.
