DP2C pairs 1080p capture with a 4.3-inch colour screen. The store’s DP2 2K adds 2K capture and touch control. EP4 offers 4K capture with a larger 5.5-inch touchscreen. For a Hong Kong front door, check fit and family operation before choosing on resolution. This comparison uses the listed versions, not the older 1080p DP2.
Core differences
| Item | DP2C | DP2 2K | EP4 |
|---|---|---|---|
| Camera resolution | 1080p / 2MP | 2K | 4K / 3840 × 2160 |
| Indoor display | 4.3-inch colour; touch not specified | 4.3-inch colour touchscreen | 5.5-inch colour touchscreen |
| Diagonal field of view | 155° | 166° | 160° |
| Consider for | Straightforward indoor visitor viewing | Touch operation in a smaller screen size | A larger screen and higher capture resolution |
| Check | Do not assume touch support | Confirm the full 2K model name | Allow space for the larger indoor unit |
Camera resolution is not the display panel’s native resolution. The field-of-view figures above are diagonal and should not be directly compared with horizontal figures. A wider view captures more area but makes distant subjects smaller; angle alone does not establish better detail.
Choose around how the household answers the door
Consider DP2C for basic indoor viewing, DP2 2K for touch operation, and EP4 where a larger screen is useful. Ask the person who will use it most to check the controls and mounting height. A product page labelled only DP2 may describe a different version, so compare full model names.
Measure before fitting
Check door thickness, existing peephole diameter, clearance on both sides and the chosen model’s installation guide. EP4 lists a 14–50mm hole and 35–105mm door thickness; do not apply those measurements automatically to DP2C. Using an existing hole does not remove door, tenancy or estate requirements. Read our Hong Kong doorway CCTV privacy and permission guide.
Wireless still needs power and a suitable connection
Rechargeable viewers need a charging routine. Visitor activity, viewing and alert settings affect use, so advertised standby figures are not a household runtime guarantee. Test the actual position with any metal gate closed. Confirm compatible card capacity, Hong Kong CloudPlay availability and the chosen recording mode; cards and optional cloud services are generally separate purchases.
Decide retention separately from picture quality
Do not assume a battery peephole viewer provides continuous 24-hour recording. Check supported modes before planning storage with our CCTV recording capacity guide. These products view and communicate with visitors; they are not automatic door locks.
Frequently asked questions
Are DP2 and DP2 2K identical?
No. A page named DP2 may describe an older resolution version. This article concerns the store’s DP2 2K; confirm the full model before buying.
Does a 4K camera mean a native 4K indoor screen?
No. Capture resolution and display-panel resolution are separate specifications. We do not describe EP4’s screen as a native 4K panel.
Can a metal gate obstruct the view?
Yes. Check gate bars, opening direction and lens position with the door and gate closed. Resolution cannot see through an obstruction.
Can I fit one without an existing peephole?
Do not assume installation without door alteration. Confirm door and permission requirements before arranging a suitable installation assessment.
Browse smart peephole viewers and video doorbells, read the peephole vs video doorbell guide, then review account and family-sharing security.
A doorway camera without drilling: measure the existing opening
For a doorway camera without drilling, an existing peephole does not guarantee an alteration-free fit. Measure opening, door thickness, clearances and gate obstruction, and confirm permission. Review local and cloud recording costs and IP camera offline troubleshooting separately from physical fit.
