Check the cable before you buy the drill bit

Measure the tails before you mark the wall. On the one-monitor TMEZON, United Kingdom reviews describe the supplied tails as about four inches, and the extension cable is not included. The two-monitor TMEZON includes a 1 metre test cable, two monitors and two power supplies, and still omits the extension to a real front door. Two doorbell wires are not that extension. TMEZON, the V168, LUCINE, JASAG and ReaIOKbii need four cores. The EZVIZ CP5 claims a 2-wire installation and 4-wire compatibility. One UK review said two wires indoors were required, found no diagram, and returned the kit. If the cable is in a block and you do not own it, stop. The choice of link is the wired or Wi-Fi video intercom page.

Check the plug, then test on the floor

The V168 is the only listing here that names a 3-pin UK adapter, and another bullet says the power supply is not included. EZVIZ’s included line says 36 EU, which does not confirm a BS 1363 plug. JASAG prints 230 volts and does not confirm the plug form. A European plug is a return or a proper adapter, not a reason to chase cable. Prove speech and picture on the floor with the short lead. TMEZON mounts with screws. Winnes can use adhesive or screws, and the link should be tested before the outdoor unit is fixed. Drilling, or sticking the pad, is the point of no return.

When the job is not a plug-in monitor

A plug-in extra-low-voltage monitor supply is a different job from work at the consumer unit. In the Building Regulations 2010, extra-low voltage is not more than 50 V AC or 120 V DC. Approved Document P is the England publication. Notifiable work includes a new circuit, a replacement consumer unit, and work in a bath or shower zone. Fixed equipment on a 13 A plug can still sit inside Part P and be non-notifiable when it is not that work. Part P in England is not the rule you quote unchanged in Scotland or Northern Ireland. Stop and call an electrician in four situations. You need a new mains circuit or a consumer-unit change. The lock is on a door people would use to escape. The cable runs through a block you do not own. The kit is the Hikvision DS-KIS603-P (B) and network setup is new to you. UK reviews describe hard wiring or Power over Ethernet, poor documentation, and a setup that is not for a beginner.

If it fails after you have fitted it

A unit that is dead the next morning is a fault, not a reason to chase more cable. Under section 22 of the Consumer Rights Act 2015 you have 30 days to reject goods that are not of satisfactory quality, then repair or replacement, with a six-month presumption against the trader. A missing strike is not that fault when the listing never included a lock. TMEZON, ReaIOKbii, KurDunly, EZVIZ and Hikvision claim a release and omit the strike. A kit that will not show a picture on the short lead, before any drilling, is the one to reject while it is still a parcel.

Common questions

Can I reuse the two wires from the old doorbell?
Only if the kit you bought is specified for two wires. The four-wire kits in this set are not. Two bell wires leave you short of two cores, and a four-inch tail from a TMEZON box does not become a hallway run. The EZVIZ listing claims two-wire and four-wire compatibility, and a UK review still found no diagram.
Should I drill before the picture works on the bench?
No. Connect the short lead, match the cores from that kit’s sheet, and get speech and a picture before you mark brick. Winnes should be tested before the adhesive or the screws go in, because one review unit stopped after five minutes and the range line is open spaces.
Does plugging a monitor into a socket need Building Control in England?
A plug-in extra-low-voltage monitor supply is not the same as a new circuit or a consumer-unit change. Approved Document P makes a new circuit, a replacement consumer unit, and work in a bath or shower zone the notifiable examples to plan around in England. A 13 A plug can still be within Part P without being notifiable. Scotland and Northern Ireland are not this paragraph. If you are opening the consumer unit, call an electrician.
Who fits a Hikvision IP kit?
Someone who already configures IP cameras, or an installer they hire. UK reviews of the DS-KIS603-P (B) say the setup is not for a beginner, the documentation is poor, and retail support was refused without a trade account. The box lists two power supplies, and reviews describe hard wiring or PoE, which conflicts with any easy-wireless sentence on the page.
What if the unit is dead the next day?
Stop drilling. Section 22 of the Consumer Rights Act 2015 gives you 30 days to reject faulty goods, then repair or replacement. A LUCINE review describes a unit that failed just as the buyer thought that window had closed, and another describes support that did not help.
